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.

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.

Flawless performance in any audio environment
Today?s venues face a growing need to provide a multiplicity of audio feeds
from presentations, conferences, orchestral performances and lectures. The
advent of digital broadcasting, the growth of webcasts and direct-to-CD
archiving highlight the deficiencies in audio splitting systems more than ever
before. Whether the final product is a broadcast feed or CD sales of an unrepeatable
lecture, performance or event, end-users? expectations of audio quality are
higher than ever.With these requirements in mind, ARX has developed the
MSX 8 Active Microphone/Line Splitter to deliver the performance required by
today?s standards of audio production. Active microphone and line splitting has
a number of benefits over passive splitters: primarily these are improved sound
quality, noise figures comparable to the best microphone inputs, and increased
resistance to RFI. All of which translate into superb audio quality for your clients.
About the MSX 8
The MSX 8 consists of two channels of actively buffered ultra low noise Microphone/
Line Splitter. Each of these channels has four electronically Balanced splits ? two
on the rear panel, plus two more on the front panel. All four output splits have the
option of transformer balancing if so specified.Each channel has a ?20 dB pad switch
plus silently switchable 48V Phantom power with indicator LED.Gain through the MSX 8
can be set individually by the small DIP switches on the rear of each channel, from 0dB
through to +40 dB in 10 dB stepsA ?Link? switch links Channel 1 to Channel 2, providing
an ultimate maximum of 8 Outputs from a single input. An indicator LED shows when this
is active. A Clip LED indicates imminent signal overload through the channel, and a
numbered marker panel on the front provides a space where individual channel connections
can be noted.For remote or mobile applications a 5 pin DIN connector on the rear panel
provides an access point to connect a 12V DC power supply
Inside Information
Internally, powerful RF input filtering removes both common mode and differential interference
at ultrasonic frequencies and above. High CMRR is achieved by the use of precision components
throughout.Advanced user options include internally jumper linking Inputs to Main outputs, and
Ground lifting Output Pins 1as required.
Internal Power Supply
The MSX 8 has a low noise transformer based power supply to obtain the maximum benefit from
the ultra low noise design of the splitter circuitry.
Summing up, the feature packed MSX 8 is the answer wherever transparent signal buffering and
routing is required.

| The MX225 is designed for remote volume control of multiple amplifiers or powered speakers in a distributed audio system. Two stereo sources are available to each of five output zones. Each source input pair handles separate left and right balanced line level signals. Each output zone features independent level control from inputs 1 and 2, stereo/mono selector with mono indicator, LED level metering, and left and right balanced line level zone outputs. All audio connections are balanced XLR. The built in power supply and single high 19″ rack mount format allows for easy installation and reliable operation.
