3 Adjustment selector button and LEDs — Press and release this
button to select volume, bass, or treble adjustment. When an
adjustment is selected, the corresponding LED lights. If after 10
seconds you do not make any other adjustments or selections on
the front panel, this selector will default to volume.
The adjustment selector button will not function unless
you have first selected one or more channels (see

,
above).
4 Adjustment knob — Turn this knob to adjust the volume, bass,
or treble for the channel(s) you selected using the channel
selector buttons. When you reach the upper or lower limit of
the allowable adjustment range, the adjustment selector LED
flashes three times. (See chapter 3, “Remote Control”, for
instructions on setting volume and tone limits.)
The volume adjustment is speed sensitive. Turn the
knob quickly to make coarse volume adjustments or
slowly to make fine volume adjustments.
Channel ties
The user can tie the two channels in a group together for stereo
audio.
Creating a tie
To tie channels together:
1. Press the channel selector button until both LEDs are on.
2. Press the adjustment selector button to select either
volume, bass, or treble and turn the adjustment knob in
either direction.
The RAC 104 automatically sets both channels to the same
volume or tone level using the following criteria:
For volume — The unit changes the volume setting for the
channel with the highest volume to match that of the other
channel.
For example, if the volume on channel 1 is set to 85 and
the volume on channel 2 is set to 50, the unit will change
channel 1’s volume setting to 50 when the user ties them
together.
Channel 1 Channel 2
Volume before tie: 85 50
Volume after tie: 50 50
For bass and treble — The unit changes the tone setting
for the channel with the tone setting farthest from 7 (0dB)
to match that of the other channel.
