Notes:
1. The 255R may be utilized as a subwoofer amplifier with
the low pass filter set to “SUB” When using the amplifier for
full frequency range speaker powering, set the low pass filter
switch to “FULL RANGE”.
*2. When the 255R is connected to a speaker level volume
control as a source feed, the 255R volume will track the
speaker volume control settings.
3. Use convenience pass-through outputs on 255R to feed
additional devices
