The OM series vocal mics from Audix have become standards in the professional audio industry. Although each of the models have been developed at different times, they fall into 3 distinct categories.
- OM2 and OM3
- OM5 and OM6
- OM7
The OM2 and OM3 are cost effective all-purpose microphones with professional performance.
OM3
The OM3 was initially developed in 1989 as an upsell to the SM58. It would outperform the SM58 in output level, feedback rejection, gain before feedback and sonic clarity. It has been popularized by vocalists such as Bruce Springsteen, Shania Twain, and Willie Nelson. It is a very clear sounding mic, especially in the lower mids where the voice tends to be muddy or boomy on other microphones. It is a great all purpose mic and even though a little more expensive than the SM58, it is an exceptional value.
OM2
The most recent addition of the OM series and was created primarily as a result of the retail market demand for a reasonable price microphone that can compete with the SM58, both in price and performance. The OM2 is optimized to sound great on a small to medium size PA.
It has many of the characteristics of the OM3, however the OM2 is given a bit of a bass boost in the lower midrange and has a bit more bass proximity than the OM3. The OM3 has lower handling noise than the OM2 and is noticeably better sounding when youget to larger PA systems.
The OM5 and OM6 are designed for the professional artist looking for the optimum
vocal performance.
OM5
The OM5 was introduced in 1995 and was soon recognized as an award winning microphone and gained popularity amongst a variety of high profile artists such as Alanis Morissette, Goo Goo Dolls, Bonnie Raitt, The Beach Boys, George Strait, and many others. It was also popularized on shows like The Tonight Show, The David Letterman Show, and MTV Unplugged.
The reason for its popularity is simple. The OM5 is a perfect blend of sonic clarity and off-axis rejection of unwanted stage noise. It’s an excellent mic for capturing the natural sound of a vocalist and separating it from the rest of the band, even on extremely loud stages. The mic can take upwards of 140 dB of sound pressure levels without distorting and very roadworthy.
OM6
As good as the OM5 is, it requires the vocalist to stay right on top of the mic while singing. Since not all vocalists are comfortable with this style of singing, the OM6 was designed to give the singer a bit more freedom of movement off the microphone. In addition, the OM6 is a very full and rich sounding mic as it is not attenuated at all in the bass frequencies (responds down to 60 Hz).
The OM6 is not quite as bright in the mid-range as the OM5 and can smooth out a vocalist who tends to get peaky or shrill. Even though the OM6 does not have quite as much off axis rejection as the OM5 in the close field (within 8” of the mic), it has comparable rejection from the far field (all instruments on stage).
OM7
The OM7 has become the ultimate mic when it comes to gain before feedback. The OM7 was designed shortly after the OM5 as an experimental microphone for extremely loud concert level music. It is a completely unconventional mic with an extremely low output level, no transformer and a fairly flat frequency response without any mid-range vocal peak.
The mic had the ability to provide more gain before feedback in the stage monitors than any other microphone (even to date). It was popularized by groups such as Nirvana, Red Hot Chili Peppers, Pearl Jam, Soundgarden, Stone Temple Pilots, and many more. Since it is a low output microphone it relies on a pre-amp or the console for its gain and it also
requires the singer to be right on top of the mic at all times. The OM7 is a “systems” microphone and is a great choice for a sound company or a permanent installation with a professional sound system.
Characteristics of All Audio OM Series Microphones
All Audix OM Series microphones have many great characteristics, including:
- Made in USA
- Excellent off axis rejection
- Natural sound reproduction
- Sonic Clarity
- Dent resistant spring steel grill
- Ability to handle over 140 dB sound pressure levels
- Low handling noise
- Black e-coat finish
- Gold plated XLR
- Each mic includes a sturdy pouch and nylon mic clip
- 1 year warranty

Direct Pro Audio is proud to be the sound system provider for the Durham Museum in Omaha, Nebraska. Join us for Christmas at Union Station 2010!
Direct Pro Audio has provided 4 Renkus-Heinz ICONYX IC-16 speakers and a wireless head end consisting of Audio-Technica 5000 series wireless microphone systems. The ICONYX digitally steered system provides beautifully clear sound for the entire Great Hall museum space, an extremely challenging acoustic environment.
As the home to Omaha’s largest indoor Christmas tree, The Durham Museum’s Christmas at Union Station is one of the region’s most cherished traditions. Union Pacific Railroad began the tradition over 75 years ago by cutting down a Christmas tree from along its right of way in the Pacific Northwest and transporting it to Omaha’s Union Station. The tree greeted the thousands of passengers arriving on trains during the holiday season in the heyday of passenger rail service.
The Durham Museum, with the assistance of many community partners has continued the tradition by accepting donations of trees from local homeowners and putting it on display during the holiday season. Each year, Union Pacific employees cut down the tree and place it in The Durham’s Suzanne and Walter Scott Great Hall. Then the talented design team from Mangelsen’s decorates the tree.
Tree Lighting Ceremony Friday, November 26, 4-7PM
The annual Tree Lighting Ceremony is a holiday favorite! Renowned vocalist, Michael Lyon will give a live performance in front of The Durham’s beautiful Christmas tree. His Frank Sinatra style of music is certain to put you in the holiday spirit. During this family-friendly event, you can also take part in cookie decorating, create holiday crafts in Mangelsen’s Craft Corner, and children can share wish lists with Santa and Mrs. Claus under the glow of the tree.
The Bow Truss Room is a large open gallery space that’s described as “not a museum, gallery, library nor research center, but an open space for open minds that nurtures and promotes creativity in the arts, sciences and philosophy.” The space hosts a wide range of programs, performances, exhibits and presentations, ranging from artists’ exhibitions and lectures to music and dance.
The space, designed by Los Angeles architect Mark Mack, joins three warehouses together via a glass and steel atrium, creating a light and airy environment that is exceptionally conducive to the arts. One of the buildings, a former truck garage, has been converted into the Bow Truss Room, a large flexible 92,000-square-foot space with concrete floor and walls and a high, curved ceiling. It’s an acoustically live space with more than enough reflective surfaces to make intelligibility an issue.
Audio for the hall was designed by Chicago-based Threshold Acoustics LLC, who specified four Renkus-Heinz PN82 self-powered two-way loudspeakers to cover the space. The system was installed and commissioned by Direct Pro Audio of Omaha.
“The room is exceptionally challenging, acoustically, with lots of hard, reflective surfaces,” says Direct Pro Audio’s John Manhart who, along with DPA’s Dan Allen, performed the installation. “The PN82′s tight focus contributed to the overall even distribution of sound, and the built-in amplification and RHAON processing let us precisely tune the system to meet the challenging requirements of this room. The Renkus-Heinz speaker voicing sounds amazing, and there is plenty of headroom and clarity in the system.”
The space and the system made their debut with a night of music and conversation starring musician Roseanne Cash and noted musicologist Dr. Daniel Levitin.

>”Which amp should I use to power these speakers?”
It seems that this is a very common question. The answer is relatively easy, once you know the ‘secret’. Before I reveal the ‘secret’, let me take a few sentences to explain power ratings provided by speaker and amplifier manufacturers.
Speaker Power Ratings
RMS? Continuous? Program? Peak? Why can’t they all rate speakers the same way? The answer: MARKETING! Bigger numbers are more impressive. Here is a quick rundown of the terms and what they mean (in general)
RMS (Root Mean Square) – The average power which a speaker is capable of handling. Typically the most common standard professionals use to look at speaker power ratings.
Program – This is usually the power rating at which a given speaker should be consistently driven at.
Continuous – Some manufacturers use this interchangeably with RMS, others with Program.
Peak – The maximum amount of power a given speaker can handle at any given moment. In other words, a very short power spike.
Here is a very general rule of thumb: RMS is the lowest rating, Program is twice the number of watts as RMS, and Peak is twice the number of watts as Program.
Here is an example of a speakers power ratings:
RMS: 250 Watts
Program: 500 Watts
Peak: 1000 Watts.
*** Please note that this is an example, and different speakers may have different ratios on their ratings.***
Amplifier Power Ratings
Amplifier manufacturers typically provide power ratings at a specific impedance rating. HUH? This simply means for a number of ohms, 8 ohms and 4 ohms being the most common, and occasionally, 2 ohms.
Here is an example of an amplifiers power ratings:
Stereo 8 ohms: 450 Watts
Stereo 4 ohms: 650 Watts
Stereo 2 ohms: 1200 Watts
Bridge Mono 8 ohms: 1300 Watts
Bridge Mono 4 ohms: 2400 Watts
***Please note that, again, this is an example, and different manufacturers will have different ratios of power from impedance to the next.***
OK, So how do I pair up Speakers to Amplifiers?
Here is a little analogy to use with speakers and amplifiers.
A worker can lift 200 pounds. During his 8 hour shift, all he does is carry 200 pounds from place to place. At the end of his 8 hour shift, the worker is very tired, as he did the maximum amount of work he can do.
This same worker is asked to lift 300 pounds. He can do it, but after 4 hours he is so tired, he cannot do any more work.
The same worker is asked to carry 100 pounds. The worker can do this easily. At the end of his 8 hour shift, he is tired, but not nearly as worn out as when he carried 200 pounds all day.
In this analogy, the worker is the amplifier, and the weight he is carrying is the speaker.
When an amplifier that is capable of 500 watts is put onto a speaker that is rated at 500 watts, then that amplifier is doing the maximum amount of work it is designed to do. When the same amplifier is powering a 700 watt speaker, it is working harder than it was designed to work, and is very very inefficient. When that same 500 watt amplifier is driving a speaker rated at 450 watts, it is working just as hard, but is more efficient at doing the work.
THE SECRET
Power your speaker with +/- 20% of the wattage it is rated at, using the ‘Program’ power rating.
Example:
For a speaker rated at 500 Watts, power it with 400 to 600 Watts of power from the amplifier.
(500 Watts x 20% = 100 Watts, 500 Watts – 100 Watts = 400 Watts, 500 Watts + 100 Watts = 600 Watts)
It’s that easy! Following this system, and running your equipment properly, should lead to a long, happy relationship between you and your sound system.

 WEST SPRINGFIELD, MA — Jennifer Nettles and Kristian Bush, the country music duo called Sugarland, have been touring North America with their band, using more than three-dozen channels of Sennheiser wireless vocal microphone, personal monitor and instrument systems.
Sugarland’s use of the Command option on the SKM 5200 RF handheld vocal mics, in particular, is “a cool feature that we all love,” said Steve Ledet, monitor engineer for the tour. At the touch of a button, the Command feature re-routes the SKM 5200’s capsule to a second output channel. In Sugarland’s case, that Command channel is sent to all of the personal monitors, as well as to speakers at the FOH position, allowing Nettles and Bush to communicate privately with their musicians and crew. “Jennifer uses it all the time,” Ledet said. “For example, during stadium dates on this summer’s Kenny Chesney tour, she would be out on the thrust in front of 60,000 people and ask for more vocal, more snare drum, or more of Kristian’s guitar in her ears. If they’re running out of time in the set and they need to cut a song she can just tell the band in-between songs. Or she’ll be grabbing a drink of water and she’ll ask them to double up on the intro.” He added, “I have it cranked up so there’s no mistaking between her vocal and that. It really is invaluable, and the audience never knows that she’s dealing with anything. It’s the coolest thing ever as far as I’m concerned because she doesn’t have to look at me or wait for eye contact — she just talks. She has complete communication to me. All she has to do is push the button.” Andy Hujdich, who oversees the 93 channels of onstage patching, calls the new feature invaluable in terms of time saved when an on the fly patch is necessary. Sugarland’s FOH engineer and production manager David Haskell, who formerly toured with Alabama, Keb’ Mo’, and Gretchen Wilson, runs down the list of Sennheiser wireless gear in use onstage. “We’ve got tons of Sennheiser gear out on the road with us — every instrument, all ears, and all the vocal mics,” he said. Nettles and Bush each use the SKM 5200 outfitted with the MD 5235 dynamic capsule. “Those microphones sound incredible,” Haskell said. Additionally, each of the five backing musicians supplies background vocals via an e 935 wired vocal mic. “I also use MD 421s on both of our bass rigs, and as a low microphone on the Leslie,” Haskell added. “I’ve used those things for a hundred years on drums. I’d use a hundred of those things if I could find a spot to stick ‘em.” Haskell had good things to say about the EM 3732 mic receivers that are paired with the SKM 5200s. “That thing is impeccable. I’ve never had those vocal mics drop out. We’ve even taken it to ‘Oprah’ with us, and places like that where RF is not simple.” Ledet also noted how easy it was to learn the operation of the EM 3732. “I’ve never even seen a manual for that thing and it’s just a piece of cake to get around on and change frequencies. It does its own scanning, and to synch it takes about two seconds. That’s real convenient when something pops up all of a sudden; I can pretty quickly find an open frequency and get the mics tuned back in.” Ledet additionally oversees a dozen ew 300 PM G2 units. “I’m only using nine of them at a time,” he said. “I’ve got seven band members, including the principals, my cue mix, and I use one for the guitar techs. We have the extras for guests. The PMs operate in conjunction with AC2 combiners and A 5000-CP antennas.” Guitar tech Steve Castro looks after 10 channels of ew 372 G2 for Bush’s various wireless instruments, plus additional channels for Nettles’ acoustic guitars and for bass player Annie Clements. Jill Hall, stage right guitar tech, handles two units for guitarists, Scott Patton and Thad Beaty. Despite there being just short of forty channels of Sennheiser wireless equipment onstage, says Haskell, “The RF has been like a rock.” For more information, please visit www.sennheiserusa.com.

According to the National Institute for Occupational Safety and Health (1998), the maximum exposure time before hearing damage at 85 dBA is 8 hours. At 110 dBA, the maximum exposure time is one minute and 29 seconds. If you must be exposed to noise, it is recommended that you limit the exposure time and/or wear hearing protection.
The following are decibel levels of common noise sources around us. These are typical levels, however, actual noise levels may vary depending on the particular item. Remember noise levels above 85 dBA will harm hearing over time. Noise levels above 140dBA can cause damage to hearing after just one exposure.
Points of Reference measured in dBA or decibels:
- 0 – The softest sound a person can hear with normal hearing
- 10 – normal breathing
- 20 – whispering at 5 feet
- 30 – soft whisper
- 50 – rainfall
- 60 – normal conversation
- 110 – shouting in ear
- 120 – thunder

Remember that the decibel (dB) is a logarithmic unit, meaning that you cannot add and subtract dB like ordinary numbers. For example, an increase of 3 dB is a doubling of the “strength” of the sound, and an increase of 10 dB means that the sound is 10 times as loud; i.e., 70 dB is 10 times as loud as 60 dB.

One of the most frequent questions we get is the difference between stereo, parallel, and bridge mono modes in Amplifiers
Stereo Operation
Stereo operation mode is the normal, default mode of an amp. This means that the amplifier provides power to two independent channels. Think of it as two amps in one. Many recent amps can even run two different power/resistance ratings on the two channels at the same time. Usually we run two outputs (left and right) from a mixer, into the two amp channels (left and right), and then into two speakers set up in front of an audience, one on the left, one on the right. This enables an audience to enjoy the stereo effects of music.
Parallel Operation
Parallel operation routes an identical audio signal of one amp input into both channels. You use this to route a mono input (like a microphone, or mono output of a mixer) into both channels of an amp. It is the same as using a Y cable to split a mono input into both channels. After the input, the amp acts exactly like a stereo mode amp.
Bridge Mono Operation
Bridge mono mode combines two amp channels into one mono, much more powerful amp channel. This is most often used for subwoofers. Amplifiers have separate stereo and bridged mono power handling specifications. For instance, the Alto MACRO 1400 amp is rated at 310 W at 8 ohms STEREO, and 900 W at 8 ohms BRIDGE MONO. The advantage of bridge mono is that you have a much higher power rating; the disadvantage is that you have only one amp channel.
Connecting speakers to an amp in bridge mono mode is different from stereo mode. Usually you connect a banana plug to the middle two banana outputs. You must also flip the amp into bridge mono mode, using dip switches on the back of your amp. Consult your amp manual for specific directions on your particular model.

LAS VEGAS — Mark Amundson, the technical editor of FOH, died on Friday, Sept 4 from what appear to be complications after surgery. An autopsy has been requested but not performed at the time of this writing. Mark was not only an integral part of the FOH team, he was a longtime, close friend, a devoted husband, and he was passionate about audio and music in general. He will be missed in ways we can’t even express. Services are planned for Friday Sept. 11 in his hometown of Cambridge, Minn. Fittingly, after a short prayer service, the plan is for lunch and a final jam session in his honor at the local American Legion Hall — a venue where Mark both played and did regular sound gigs.
