ARX Signal Processing: Superb
Audio Quality About the
MSX 32 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. 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.
The PFL busses of multiple MSX32 units can be linked by
connectors on the rear panel. Gain through the MSX 32 can be set
individually by adjusting the rotary Gain control on the
front panel 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. Each channel also has a rear
panel switch hard-linking the Input to the Main
output. 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. Internal
Power Supply and the PSU32 Redundant back-up supply However, for
“critical” applications where systems must keep
operating, we recommend including the optional PSU 32
redundant power supply unit. An illuminated power switch
on the front panel provides visual confirmation of AC power
connection to the unit. To sum up, this feature
packed two RU device is the answer wherever transparent
signal buffering and routing is required. Signal / Noise Ratio

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.
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
uses an internal toroidal transformer based power to get the
maximum benefit from the ultra low noise design of the
splitter circuitry.
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.
