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 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.

More sound to your amps and speakers
The secret to making speakers sound great lies with the crossover you use. With the dbx® 223xs Crossover you\'ll get great performance, ultra low-noise, rugged reliability and four decades of dbx knowledge and expertise in building the world\'s finest processors. The 223xs uses precision filters to separate the audio signal and direct the correct frequencies to your loudspeaker drivers. By directing only the specific frequency bands to each speaker driver the 223xs leaves your amplifiers free to use their full power on the usable signal eliminating distortion and giving your PA system a cleaner and better sound.
The dbx 223xs is a dual channel crossover with all the features you would expect from a professional product. It features Linkwitz-Riley 24dB per octave filters, independent output gain controls for level matching, output phase inversion, 40 Hz low cut filter, and optional mono summing of the low frequency (subwoofer) output. Everything in the design exudes great precision from the solid "click" controls to the high quality XLR inputs and outputs

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.
