Kramer Electronics has released both an iPhone App and PC based control software for Kramer’s popular VP-729 ProScale Digital Scaler/Switcher. The new iPhone App and the PC based control software provide easy-to-use interfaces to control both switching and operation of all menu features of the VP-729.

Kramer has created an iPhone App called “VP-729” that allows users to conveniently operate Kramer’s popular VP-729 scaler/switcher. The VP-729 App provides an intuitive and easy-to-use interface for the most necessary functions of the VP-729. To operate, enter the IP address of your VP-729 and press the connect button. You can switch inputs, increase and decrease the audio output volume and adjust all menu items over your wireless network. There is no need to manipulate the front panel buttons or look for the wireless IR remote control. Just grab your iPhone and start working.

The new iPhone App can be found in Apple’s App Store within iTunes®. Once in iTunes, search for “VP-729” and download the app. There is a video posted a video on YouTube demonstrating how to use the VP-729 App.

Kramer has also created new PC-based software for the VP-729 that also works with the VP-728 via the RS-232 port. This freeware switching and control program can be obtained from the Kramer Web site via the “Downloads” tab on the VP-729 or VP-728 product pages. After the program is installed on a local computer, it connects via Ethernet to a Kramer VP-729 or via RS-232 to either a VP-729 or VP-728. All the switching and menu functions of the VP-729 and VP-728 can be set and controlled remotely from the connected computer.

The PC-based control software emulates the appearance of the front panel of the Kramer VP-729/VP-728 scalers on the computer screen so that the user can control switching by clicking on the inputs buttons. If menu control is selected, the VP-729/VP-728 menu appears on the computer screen. The on-screen menu is visually identical to the menu generated by the scalers on a connected display and the user has full control over all features including the ability to define and set custom resolutions.

The new VP-729 and VP-728 PC-based switching and control software can be found on the VP-729 or VP728 product pages via the “Downloads” tab or under the heading “Software” on the “Software Firmware Updates” page on the “Support” tab of the Web site at . It is available at no charge as a value-added freeware program.

FCC Consumer Alert on Wireless Microphone Issues

AddThis Social Bookmark Button

As of February 28, 2010, we are required to post the following announcement to every single page of our website where wireless microphones are for sale.  We've complied with that request delivered to us via U.S. Mail as of February 25, 2010.

You might want to take a look at the notice.  Of course, you'll see it on every page of the site where wireless products are for sale.  Take a minute to read the notice and if you have questions, please feel free to call us.



Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at


What does this mean?  In a nutshell, it means that if your wireless microphone (any unlicensed wireless microphone) may not interfere with anyone else's licensed wireless microphone or other radio system and that, as an unlicensed user, you have no assurance of reliable wireless microphone performance.

That said, today's wireless microphone systems are the most advanced and best sounding systems ever made.  They are reliable and will work well for you in the current radio climate.  You can expect good performance.  If you have 700MHZ wireless systems, it's time to get new ones.  The FCC has ruled that all units operating between 698-806MHZ be phased out effective June 12, 2010.

We can help you make the best decision for new wireless microphones going forward - whether or not you have existing microphones that need to be replaced.



Audio-Technica Sounds Off at the Grammy Awards!

Los Angeles (February 2, 2010)--For the 13th year in a row, Audio-Technica supplied more than 250 microphones for the annual Grammy Awards Show.

2010_grammysThe 52nd Annual GRAMMYs, held January 31, 2010 at the Staples Center in Los Angeles, placed an emphasis on live performances. For the live show and broadcast, Audio-Technica supplied hard-wired mics and Artist Elite® 5000 Series UHF Wireless Systems, as well as its new AT4050ST Stereo Condenser Microphone and AT4081 Bidirectional Ribbon Microphone.

The sound system was provided by ATK AudioTek with FOH (front-of-house) Engineers Ron Reaves and Mikael Stewart, with the house audio supervised by Leslie Ann Jones, a prominent member of the Producers & Engineers Wing of The Recording Academy. New Jersey/California-based remote facilities company Music Mix Mobile were onsite with their M3 trucks to create the music mix, facilitated by Broadcast Music Mixers John Harris and Eric Schilling, while Tom Holmes was responsible for the overall broadcast mix. The broadcast audio was supervised by Phil Ramone and Hank Neuberger, also leading members of the P&E Wing. Michael Abbott returned as Audio Coordinator, and Music Mix Mobile’s Joel Singer served as Engineer-in-Charge.

For the home audience, CBS delivered the most advanced form of HDTV, with 1,080 lines of picture resolution and 5.1-channel surround sound. To meet the sonic demands of this format, the audio engineers and music mixers employed a wide range of Audio-Technica microphones for the GRAMMY Awards.

Artists who performed throughout the evening using Audio-Technica’s Artist Elite 5000 Series UHF Wireless System included Jamie Foxx, T-Pain and Doug E. Fresh, performing Foxx’s “Blame It”; Album-of-the-Year winner Taylor Swift and Stevie Nicks, on a medley of recent Swift hits and the Nicks-penned Fleetwood Mac classic “Rhiannon”; double award recipient Maxwell; and Lil Wayne and Drake, who performed with Eminem. All of these performers used A-T’s AEW-T5400 Handheld Microphone/Transmitter, except Swift, who used A-T’s AEW-T4100 Handheld Microphone/Transmitter. Additionally, Elton John, who performed with Lady Gaga, used a hardwired AE6100 Hypercardioid Dynamic Handheld Microphone.

The backline mic complement of A-T wired microphones included AE5400 Cardioid Condenser Handheld Microphone for backing vocals and horns; ATM350 Cardioid Condenser Clip-On Microphone for strings; AT4050 Multi-pattern Condenser Microphone for guitar and bass cabinets; the new AT4050ST Stereo Condenser Microphone for overheads; and the new AT4081 Bidirectional Ribbon Microphone on percussion and guitar cabinets, as well as for Jeff Beck’s guitar amp during a tribute to late guitar legend Les Paul. Audio-Technica’s 5000 Series Wireless was also used on background vocals.

John Harris, Co-Music Mixer, stated, “For high-profile broadcast events like the GRAMMYs, we always turn to Audio-Technica because there can’t be any room for error. A-T gives us an unwavering level of confidence, as I know the mics will work perfectly regardless of the situation. Also, I have been moving away from traditional overhead microphone techniques for cymbals, and instead using a single stereo mic for the whole kit. The AT4050ST has been spectacular in this application.”

Joel Singer, Music Mix Mobile Engineer-in-Charge, stated, “Audio-Technica products always perform flawlessly from a technical standpoint, and they continue to be our company’s go-to mic because of fidelity, clarity, overall reliability and consistency from microphone to microphone. And of course the quality of audio that comes through with A-T's RF is not at all sacrificed because it's a wireless – it's transparent.”




Do You Need More Choir? - Heil PR30

COTR_Choir_2You got it.

Let me be frank. The Heil PR30 Large Diaphragm Dynamic Microphone may be the very best microphone you will ever use for your choir - at least that's what our clients tell us.

This story begins a little over six years ago when one of our clients called with a question. He asked whether I thought that a dynamic microphone would work as an effective choir microphone.  My first reaction was a definitive "maybe" but that a dynamic microphone probably wouldn't be sensitive enough.

Boy, was I wrong.

Heil PR48 - New from Heil Sound

AddThis Social Bookmark Button


December 7, 2009


(Fairview Heights, IL) Heil Sound has introduced the PR 48 large diaphragm dynamic microphone designed for kick drum use.  The PR 48 features a 1.5-inch diameter element, and is mounted in a vulcanized double shock mount, which offers complete isolation within a rugged cast metal housing. The PR 48 metal housing was designed with a slanted entrance to the 3 pin XLR so the cable assembly is easier to connect. A specially designed low pass filter sets the -3 dB hinge points at 30Hz and 8kHz with a +10 dB peak from 50 Hz to 80 Hz.  The response rolls off at 8kHz, which helps control unwanted top end “noise” inside the drum, while keeping frequencies critical to kick drum harmonics found when the beater meets the drum head. The microphone provides a 600-ohm balanced output and can handle over 150 dB of SPL.


Company founder, Bob Heil, made a decision to develop a microphone for the kick drum after talks with many of today’s top drummers and sound mixers. “The kick drum is arguably one of the most important instruments on stage or in a studio when it comes to micing. It is a tricky beast. Just because a microphone shows specs that favor low-end reproduction doesn’t necessarily guarantee good results. The feedback that I received from the pros as well as my own research, confirmed that a microphone can and needed to be developed for this purpose. The PR 48 is the end result and I am very proud of it.”


Originally featured as a part of Heil Sound’s HDK Series drum microphone kits, and now offered as a stand alone product, the PR 48 has quickly become a favorite of top drummers and sound engineers. Kick drums pounded for the likes of the B-52’s, Stone Temple Pilots, Tool, The Wallflowers and Sheryl Crow are using the PR 48 in concert. Alan ‘Nobby” Hopkinson, FOH mixer for Tool had this to say, “The new PR 48 is killer, absolutely loving it, I actually cut right back on the sub bass harmonizer I've used for ever on the kicks, as your mic is giving me all the low end I could ever need, and indeed the system can handle.”


Established in 1966, Heil Sound Ltd. has developed many professional audio innovations over the years, and is currently a world leader in the design and manufacture of large diaphragm dynamic, professional grade microphones for live sound, broadcast, recording, and amateur radio markets. Heil Sound maintains corporate headquarters and manufacturing facilities in Fairview Heights, Illinois.
