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.
Audio signal distributor with 2 inputs and 8 outputs.
Two operating modes:
1 stereo input with 4 stereo outputs.
1 mono input with 8 mono outputs.
Adjusting Output level.
Balanced LINK output for interconnecting several units.

Dimensions (WxHxD): 483 x 44 x 220 mm.
Weight: 2.75 kg. | 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.

- With improved 192 kHz sample rate for the best sound reproduction.
- Supports uncompressed 2-channel LPCM (Linear Pulse Code Modulation) audio signals.
- Supports compressed 2-channel and multi-channel Dolby Digital and DTS audio signals.
- Ideal for presentation or distribution to another room.
- The optical (Toslink) digital audio splitter can split a single optical digital input to four outputs without delay or loss of quality.
- Supports the S/PDIF and Toslink standard.
Your TV has 1 Toslink output, but you use 2 amplifiers. This requires the Toslink cable to be split from 1 into 2. An additional amplifier could be, for example, a surround set, a sound bar of an amplifier in the kitchen.

| 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.

Guarantee : 60 Months | More sound to your amps and speakers
The secret to making speakers sound great lies with the crossover you use. With the dbx® 234xs 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 234xs 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 234xs 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 234xs 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.
