This modification changes the functionality of the Channel 7/8 front panel select switch and the busing
of the audio inputs. When this modification is complete‚ the front panel switch will act as a MUTE
switch for all signals connected to the Channel 7 and 8 RCA connectors. In addition‚ both stereo
channels (7 & 8) will simultaneously feed the Left‚ Right and Aux output buses. The Select action of
the switch is defeated.
Refer to Figure 15‚ "Cutaway of circuit board showing jumper location for Channel 7/8 Modification"
while performing the following steps:
1. Unplug the SMR™821a from the AC voltage source.

3. Locate and cut the jumper J905. It is located near the power supply.
