8-Channel / 4-Way Splitter, Electronically Balanced Inputs, Transformer Balanced on A & B OutputsSuperb 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 NEW 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 two transformer Balanced splits on the front panel and two electronically Balanced outputs on the rear panel for Main and Monitor. These can be optionally transformer Balanced (Model MSX32 T/ALL).
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 steps A '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 MSX32's 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 and the PSU32 Redundant back-up supply
The MSX 32 uses an internal toroidal transformer based power to get the maximum benefit from the ultra low noise design of the splitter circuitry.
However, for "critical" applications where systems must keep operating, we recommend including the PSU 32 redundant power supply unit. Individual +V, -V and 48VDC rail LED indicators show when the PSU 32 redundant power supply unit is connected to the MSX 32.
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 rack unit device is the answer wherever transparent signal buffering and routing is required.
