- Each channel: Input: female XLR type
- Outputs: 1 parallel male XLR type, 2 transformer isolated male XLR type
- Nominal impedance for inputs/outputs: 200
- Max. input level: + 6 dBu
| 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.

EC-2 Superb Audio Quality Active microphone and line signal splitting has a number of benefits over using passive splitters: primarily these are improved sound quality, noise figures comparable to the best microphone inputs, and increased resistance to RFI. About the MSX 32 With these benefits in mind, the ARX MSX 32 Active Microphone/Line Splitter has been developed to deliver the performance required by the increasing complexity of today?s standards of audio production. The MSX 32 consists of eight channels of actively buffered ultra low noise Microphone/Line Splitter. Each of these channels has four electronically Balanced splits ? two outputs on the rear panel for Main and Monitor, plus two more output splits on the front panel. All 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. A PFL switch and 6 LED metering enables each channel to be easily checked with headphones for signal monitoring, and also for line tracing when troubleshooting. Gain through the MSX 32 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 each channel to the previous one, providing an ultimate maximum of 32 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. Number stickers are provided to give each channel an individual number for up to 40 channels when multiple MSX32s are being used.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 1 as required. Internal Power Supply The MSX 32?s internal toroidal transformer based power supply is triple shielded to get the maximum benefit from the ultra low noise design of the splitter circuitry. An illuminated power switch on the front panel provides visual confirmation of AC power connection to the unit.The headphone output and the 6 LED PFL metering are both mounted on the right hand side of the front panel. Rear panel connectors enable this function to be linked when using multiple MSX 32 units. To sum up, this feature packed two RU device is the answer wherever transparent signal buffering and routing is required.

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
