Signal distributor. 1 stereo input / 4 stereo outputs or 1 mono input / 8 mono outputs
This audio distributor is very useful to supply several audio devices with only one audio source. Its 2 operating modes allow to work with mono or stereo signals. Output level can be controlled independently.
WD 421 adapts itself to work with different impedances, ensuring that output signal level is at least equal to input signal level. It avoids any undesired attenuation and features a LED vumeter to visualize the input signal level.

| 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
