The Active Microphone/Line Splitter shall be an eight channel unit in a steel chassis eight inches (200mm)
deep and two rack units high.
Each channel shall have its input and two outputs on the rear panel plus two outputs on the front panel. Each
channel shall also have a 48V Phantom power switch on the front panel with an indicator LED, a headphone
monitoring switch, and a –20 dB pad switch with an indicator LED.
There shall also be front panel switches with indicator LEDs to link each channel, thereby providing a potential
maximum of 32 outputs from one input.
The Input headroom shall be +21dB, with a CMRR of better than 70dB, and the frequency response shall be
10 Hz to 20 KHz, ±0.5dB.
The Output impedance shall be 100 ohms electronically balanced on all four outputs per channel. Additionally
all outputs shall have the option of being transformer balanced.
The maximum Output level shall be +24dB, with a Signal to Noise ratio of –94dB unweighted. Total Harmonic
Distortion shall be 0.008% @ 0dB, 20 Hz to 20 KHz.
Gain through the unit shall be switchable to 0, +10, +20, +30, +40dB via rear panel switches.
There shall also be one male and one female XLR connector on the rear panel to allow multiple units to loop
the headphone monitoring signal.
AC power shall be supplied by a removable 3 pin mains cable, connecting to an IEC connector with integral
fuse and voltage change switch on the unit’s rear panel.
The Active Microphone Splitter shall be the ARX MSX 32.

ON THIS EQUIPMENT
IMPORTANT
- PLEASE READ THIS FIRST
THIS IS A DUAL VOLTAGE UNIT. IT IS ESSENTIAL THAT YOU CHECK THAT THE VOLTAGE ON
THE FUSEHOLDER COVER BELOW THE AC CONNECTOR ON THE REAR OF THE CHASSIS IS
SET CORRECTLY BEFORE CONNECTING IT TO AC POWER.
To change, pull fuseholder out and rotate 180
o
, then push in again. Do not insert power
cable into unit until voltage has been correctly set. Do not connect power cable to AC
power until voltage has been correctly set
