The distribution of mono and stereo balanced audio signals from a single source to multiple destinations has many applications including multi-zone sound reinforcement installations, live sports events coverage, broadcast studios, video suites, duplication or indeed anywhere high quality audio has to be distributed to a number of locations down long cable runs.
The Drawmer DA-6 is a six channel stereo (or twelve channel mono) distribution amplifier featuring XLR balanced inputs and outputs with optional transformer balancing where remote amplifiers and recorders are fed from separate power supplies.
The stereo Input features individual left/right level controls with LED bargraph metering enabling the correct balancing of stereo material or two mono signals. Each of the six outputs incorporate further left/right level controls and a Mono/Stereo switch providing the selection of either one stereo output or two mono outputs per channel. This feature allows the DA-6 to function as either a 1 x stereo input/6 x stereo outputs or 1 x mono input/12 x mono output unit or any combination of the two.
The output section consists of a Channel Select so that the individual left/right output level of each channel is displayed on the output LED bargraph and can be monitored by the Headphone jack socket. A pair of auxiliary link stereo jack sockets (TRS) are provided via the rear panel for connection to further DA-6 units for the distribution of even more channels. Features: - 1x6 Stereo Distribution Amp with Monitoring.
- 1 set of stereo (2) XLR inputs.
- 6 sets of stereo (2) XLR outputs.
- Input stage has LED level meter.
- Each output channel can be switched to mono.
- Each output channel can be individually monitored.
- Built-in headphone amp.
- Optional transformer balanced outputs.
- Electronically balanced inputs with individual left/right level controls.
- LED metering on input for balancing stereo material or two mono signals.
- Left / Right level controls on each output with a stereo / mono switch.
- Headphone jack to monitor output of selected channel.
- LED metering on output of selected channel.
- Auxiliary pair of balanced 1/4" output jacks for linking multiple DA6 units.
- 1 unit rack space.
- Inputs and Outputs are balanced XLRs at +4dBu.

1231 Dual 31-Band Graphic Equalizer
The dbx? 12 Series were designed to meet the needs of the most demanding sound reinforcement environments, while offering the simplicity of straightforward controls. The 1231 provides standard features like dual-channels, 31 1/3 octave bands, ISO frequency centers, +/- 12 dB input gain range, and switchable 40Hz/18 dB per octave low-cut filters, but also includes other insightful features. These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut range for precise gain adjustments; XLR, barrier strip, and 1/4'' TRS connectors for installation ease; balanced inputs and outputs for quiet operation; and chassis/signal ground lift capabilities for quick hum isolation. The visionary design of the dbx 12 Series makes your job easier.
The dbx 12 Series Equalizers were precision engineered to provide years of maintenance-free operation in any application. The magnetically isolated transformer, electronically balanced/unbalanced inputs and servo balanced/unbalanced outputs, RF-filtered inputs and outputs, and power-off hard-wire relay bypass with 2 second power up delay were steps our engineers took to ensure compatibility for all installations. Only the best components were utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR (ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail is contained in a 3U steel/aluminum chassis.

About the DI6s It's a fact of audio life that a lot of equipment that has to be connected to professional audio systems isn't impedance or level compatible. Interfaces Unlimited Tape/cassette/DVD/CD decks, audio for video, drum machines, synthesizers, bass guitars, computers; at some stage all these need linking up to Balanced inputs, whether the application is Live sound, Studio or Broadcast. To solve these problems, we've developed the DI-6s:
Six active D.I. (Direct Injection) boxes, plus a 6 into 1 Line Mixer, plus a 1 to 6 Splitter, All of this in a compact, all steel 1 RU package.
A Pro Audio Toolbox This unique and flexible audio toolbox allows Six independent unbalanced audio sources to easily and quietly interface with Balanced pro audio systems, either to individual channels or summed down to one Master output. But that's not all. By pressing a single switch on the rear panel the DI6s will change from being Direct Boxes and a Mixer to being a 6 way Splitter (line distribution amplifier). Now it will split an incoming signal to 6 individual outputs or zones. On the front panel, each channel has 2 IN/OUT jacks, a level control from infinity (off) through 0dB to +15dB gain, and a Clip indicator LED.The Master section has a Master volume control and status LEDs indicating whether the unit is in DI or Splitter mode. In addition, as on all ARX single rack unit equipment, each channel has a numbered marker panel ('scribble strip') you can write on for easy confirmation of channel assigns. Balanced Outputs On the rear, each channel has an XLR Balanced output, with associated Ground lift switch and status LED, to isolate the chassis and electronic grounds. The Master section has both Balanced XLR and Unbalanced Jack outputs. In addition there is a Balanced XLR input with a switch to put the unit in either DI or Splitter mode. Universal AC Power AC power range is a universal 100 to 120V or 220 to 240V AC, and is connected to the unit via a removable power lead and standard 3 pin IEC connector, with built-in fuse and voltage change switch. With so many handy functions, plus a true 'user friendly' layout, it's no wonder people call the DI-6s 'A total Audio Patching System in 1 RU!' You'll never compromise on Quality when you choose ARX

| The PRMMS8 is an ultra low noise 8-channel microphone splitter providing a direct output and a transformer isolated output for each balanced XLR input. For extra flexibility, four front panel switches enable channel linking which permits routing a single input signal to multiple outputs feeding FOH, monitor, recording and broadcast mixing consoles, or merging two input signals into a single output. For use with condenser microphones, the direct outputs serve as a path for phantom power. Each channel includes a ground lift switch to eliminate hum and interference caused by ground loops between electronic equipment connected to the PRMMS8.332.
