ProAudio Review - March 2008 - (Page 38)

BROADCAST | REVIEW by Ben Burns are used for the computer bit, which uses RS485 to communicate with a PC up to 1000m away over twisted pair cable. By connecting adjacent racks in a daisy chain, up to 48 receivers can be controlled by the PC. Audio Ltd.’s audio quality, delivered by the 2040 system, does not disappoint. With a 24Mhz switching band, enough information is squeezed down each channel to ensure a high fidelity signal with increased reliability and consistency. By using high quality components throughout the design, like the Sowter transformers on each output, Audio Ltd. has managed to deliver a fantastic sounding system. Of course, the antenna you choose to use and the way in which you set up any radio system will affect performance and range, but with a little advice from the user manual (supplied on a CD) even the novice should have a rock solid system in no time. The review system was delivered with two Audio Ltd. RMS 2040 Series Versatile enough for stage and studio applications. UK-based Audio Ltd. has been involved with audio for film and TV production since the 1960s. It's one of the industry’s leading brands when it comes to wireless audio for film and TV. You can find products like the 2020 radio system adorning the shelves of the UK’s biggest production and rental companies. can be powered from any DC source between 10v and 18v, even a car battery will work. Once you get a power source connected, simply fumble with the very well protected power switch till it clicks, and the unit will initialize each screen in order. There is no hanging about for the system to boot up, it’s ready from cold The new RMS 2040 range, design for both the studio and theater markets, includes a rack-mounted receiver for two to four channels, and a selection of transmitters for specific applications. | FEATURES The heart of the 2040 system, containing two to four receivers in a 1U space, the RK2040 APPLICATIONS Audio for film and television studio; theater audio KEY FEATURES Based on two to four receivers in a 1U space; powered by any DC source from 10 to 18V; includes active antenna distribution with two BNC inputs and outputs; industry leading small size PRICE Priced upon application/configuration CONTACT Audio Limited | ☎ 44 1494 511711 ➲ www.audioltd.com in about six seconds. Each rack includes active antenna distribution with two BNC inputs and outputs, allowing two antennas to be shared between two racks (eight channels in 2U of space). The whole design and concept is optimized for minimum size, the result is a feature rich package at least half the size of just about anything similar on the market. Using the system could not be any easier. A screen is dedicated to each receiver displaying the state of audio and RF levels and also the name, frequency, battery level, and audio output level of each transmitter. The necessary information is displayed clearly in dark conditions thanks to the backlit LCD screens, with adjustable brightness and contrast settings to suit. When you need to change a receiver setting, the four push switches adjacent to each screen provide a quick way to navigate a simple menu system. All the settings for the receiver can be changed from here, and information from a currently tuned transmitter may be monitored here, like the battery level. The RF level and audio level are also displayed. The connection panel on the back includes two antenna inputs and two antenna outputs on 50 ohms BNC posts. The power input is a 4pin XLR connector, for use with the supplied mains transformer or sources like a camera battery pack – anything DC between 10 and 18 volts will work. Two 9-pin D-Sub connectors dipole antennas fixed to a clamp, and two of the standard ‘whip’ varieties. The audio outputs are provided on gold plated XLR connectors, each one being transformer balanced and adjustable from line level down to mic level. This very compact MiniTX Beltpack Transmitter is about the size of a credit card, with enough thickness for two 1.5v AAA cells. The belt-clip can be removed by sliding it off the pack, leaving a smooth oval rectangle that sits in the provided cloth pouch and is very comfortable to wear. This box of tricks is very light, and much easier to conceal than previous systems. The best thing about it has to be the talent-friendly remote control, which means you don’t have to handle the unit until a change of batteries is required. At the top of the pack, you find a smooth ‘dome’ with recessed connectors for the antenna (SMA connector) and microphone (LEMO connector). The dome conceals some LEDs and infra-red ports for the remote control, which is the only way to adjust pack settings. There are really two different types of remote control; the infra-red version is like a car alarm key fob with four buttons to navigate through each menu, while Control-X uses magnetic induction (like a hearing aid) to transmit through clothing and switch transmitters on or off, and display other information like frequency. The battery compartment is hidden under the end of the pack, which pivots in the middle like a swinging bridge to reveal the two AAA 38 | ProAudio Review | March 2008 Subscribe to the Digital Edition of Pro Audio Review http://www.proaudioreview.com/subscribe www.proaudioreview.com http://www.audioltd.com http://www.proaudioreview.com http://www.proaudioreview.com/subscribe
