Quick Change Transistors

Visitors of NAB ’13 were impressed with BW Broadcast’s commitment to make the most reliable and easily maintained FM transmitter possible.  As was Radio’s panel of engineers who awarded the new V2 transmitter range a Pick Hit award. One example of this design principle is BW Broadcast’s unique Gold Clamp Transistor Technology found on the TX600 V2, TX1000 V2 and TX1500 V2.

How Does it Work?

Gold Clamp allows MOSFETS to be changed in minutes with only a screwdriver and without needing a soldering iron. Should a transistor fail, several screws are removed, a new transistor dropped in place and then the clamping PCB replaced over the top. It’s as simple as that! This greatly reduces the time and tools required should a device fail, and prevents damage to surrounding components as a result of the high temperatures required with traditional soldered transistors. The clamping mechanism also ensures optimum thermal conductivity to reduce transistor temperature and extend service life.

There’s more…

Visitors of NAB ’13 were also impressed with V2 Transmitter’s slide in power supplies which make replacement a breeze. A truly innovative heatsink design ensures ultra-long life thanks to ingenious airflow. Carefully chosen fans rated with over 10-years life at 120°F are another sign of BW Broadcast’s commitment to service life. All of these design considerations combine to make one of the most reliable, and easily maintained transmitter to date.

BW Broadcast’s Chief Service Engineer William fears the ultra-reliable V2 will put him out of a job “I don’t have any work to do, these transmitters just don’t fail. Even if there is an issue due to lightening it’s usually fixed in the field with a slide-in power supply or quick-change module. I won’t have a job next year.”

Ariane Relaunched

Anyone who owned an FM radio station and was passionate about audio processing in the 90s or Naughties will have heard of the Ariane – the original and award winning – windowing automatic gain control (AGC) utility processor that became popular in New York City and beyond.

The original analogue version of this amazing audio processor was designed by David Reaves, a respected audio processing guru and veteran chief engineer in the major US markets. Together with Jim Huste, their company TransLanTech built, marketed and sold their Ariane processor to some of the world’s leading radio stations.

David reaves Impressed with the Ariane and the DSPX

In 2005, David and Jim were introduced to BW Broadcast’s digital ninja CEO Scott Incz through their common friends, Pyers Easton and Marcus Bekker of SBS, who at the time were assisting TransLanTech with the manufacturing the original analogue version of the Ariane. David wanted to revamp his Ariane concept, and to add some new features that were only possible by employing digital signal processing techniques. BW Broadcast’s experience and expertise in DSP audio processing and success with their DSPX processing platform resulted in a corroboration that brought the Ariane sequel processor to market in less than 12 weeks from their initial meeting. The rest they say is history.

Fast Forward To 2013

BW Broadcast not only continues to manufacture the Sequel, but has taken over the rights to the Ariane products and brand. The agreement between BW Broadcast and TransLanTech ensures the continued manufacturing and support of this iconic brand.

Scott’s glad to report -

“We are pleased  to have sole ownership of the respected and iconic brand. We are looking forward to marketing the amazing Ariane sequel to a larger audience, and at a new lower price point, that we are sure will prove popular with radio stations around the world.”

David Reaves had the following to say -

“In the original analog product that became known as “Ariane” (named after my wife, violinist Ariane Reaves), I pulled together a combination of a number of concepts that at the time had already been well-known in the realm of processing for broadcast. These included such ideas as RMS detection, subtractive crossovers, and release gating. Most important, however, was using ‘hysteresis gain control,” an idea patented by the late Emil Torick at CBS Labs who had called it “gain platforming with gated gain stabilization” for their 1960′s-era ‘Audimax’ products (and which Glen Clark had adapted with his 1980′s era ‘Texar Audio Prism’ after the CBS patents had expired).

In 1990, when I was the Chief Engineer at Z100 radio in New York, I was introduced to a ten-band monster AGC processor (analog, of course) called “the Tailor”. It used basic dbx RMS processing control in conjunction with an octave equalizer. After using it as a pre-processor on the air for a while, I concluded that it was a bit TOO much control. I decided to add some sophistication that would trade off a bit of this brute power in exchange for a more finessed, reduced-audibility means of control. I interrupted the control circuits for each band and inserted my own version of the Audimax/Texar hysteresis release system, modeling it as close as I could get it to the Audimax methods.

At Z100 I also played with processing in a stereo matrix, and toyed with enhancing low-frequencies with resonant high-pass filtering and using low-frequency mono-summing to reduce multipath-induced reception distortion. These concepts, too, later became part of the original Ariane.

Jump ahead about 15 years…the analog Ariane was a success in the sense that its control methods had become much-admired within the Broadcast industry and it had found customers in radio and TV stations in dozens of cities around the world. But being an analog product in a now-digital world, it was at a serious disadvantage, both in function and marketing opportunities.

In what has to be one of the fastest product-development cycles ever, Scott took my Ariane concept description, embellished it to include programming and remote control features I had only dreamed of, and had a functional, all-digital demo product built in about three months. The Ariane Sequel was born!”

The Ariane sequel is available now from BW Broadcast dealers around the world.

V2 FM Transmitters

BW Broadcast is proud to announce the launch of V2, the next generation FM Transmitter line. Lucky visitors of NAB ‘13 will be the first to see the new range and learn how it will benefit their station at the BW Broadcast booth C3322.  If you are attending NAB come along to our drinks reception at 4PM on Tuesday.

BW Broadcast’s renowned transmitters have been getting stations on the air for over 15 years, and have been LPFM certified for 12 of those. The tried and tested platform is now being taken to a whole new level thanks to years of experience and feedback.

Sound Great

All BW Broadcast equipment is designed and built with three mantras, performance, reliability and ease of use. The inclusion of multi-band DSPX audio processing means stations without a dedicated processor sound great, right out of the box. Those who already have external processing benefit from BW Broadcast’s unique dual-loop virtual VFO exciter and field proven ultra-low distortion modulator integrated into a great performing, highly stable FM transmission system.

Simple Maintenance

Engineers responsible for service and maintenance will fall in love at first sight. “Gold clamp” transistors on the TX600 V2 and above can be changed in minutes with only a screwdriver and without needing a soldering iron. Slide-in universal power supplies on 2U models make replacement a breeze and a truly innovative heatsink design ensures ultra-long life thanks to ingenious airflow. Carefully chosen fans rated with over 10-years life at 120°F are another sign of BW Broadcast’s commitment to service life.

BW Broadcast’s Chief Service Engineer William fears the ultra-reliable V2 will put him out of a job “I don’t have any work to do, these transmitters just don’t fail. Even if there is an issue due to lightening it’s usually fixed in the field with a slide-in power supply or quick-change module. I won’t have a job next year.”

Advanced Control

Added to this is an Ethernet connection on every V2 with smart phone apps for simple remote management. Intelligent alarms and email alerts ensure busy engineers can manage their stations with minimal intervention. A real time clock and comprehensive logging is available for those who like to see more detailed status. A high resolution OLED display for metering processing also makes setup simple. Experienced engineers will love how much control they have at their fingertips, and will find themselves eager to install their next V2 transmitter.

Available from 5W-1500W, the first models are shipping following NAB. To be one of the first to see the V2 transmitter range, contact your local dealer now.
