4. Installation
The ideal place for the XTM-300 is in the sound rack or projector console between the audio
processor and monitor or power amplifiers.
Crossover Wiring
1. Power: Connect the unit to the AC power outlet using the standard IEC cable provided.
Any power source from 100-250VAC, 50-60 Hz will be sufficient.
2. Bypass power: Connect the unit to the AC power outlet using the supplied modular power
supply. Any power source from 100-250VAC, 50-60 Hz may be used by changing the AC
pin adapters.
3. XTM input from processor outputs: Use the male-female 25 pin D cable to connect the
output of the cinema processor to the main input of the XTM.
4. Crossover outputs to monitor inputs: Use the male-female 25 pin D cables to connect the
output of the XTM to the main and option inputs of a CM series monitor (CM-8E recom-
mended). Note that the CM-8E provides a spare input which may be routed through the
XTM’s high band terminal block.
5. Terminal blocks are also provided to allow wiring to other monitors that have differing
pinouts. All crossover outputs are balanced. Use two conductor shielded cable to mini-
mize ground loops and hum.
6. Crossover outputs to power amplifier inputs: Use the terminal blocks provided to wire to
traditional amplifiers directly. All crossover outputs are balanced. Use two conductor
shielded cable to minimize ground loops and hum. Connect each of the crossover channel
outputs to the appropriate amplifier input.
7. DB25 connectors are available on the back plane to make installation quick and easy.
Alternatively, terminal blocks allow the use of stripped and tinned wire. They are pluggable
for easy service and troubleshooting.
