4. Volume Adjustment
From either the front fascia of the AM-77 (F3) or the RC-77 (RC4), select the desired volume.
While adjusting volume levels, there is an audible “click” from AM-77 and the speakers. This is the normal
operation of the relays within the
OptiLevel
® direct path precision volume control.
5. Rear Inputs
At the rear of the AM-77, there are 5 inputs for the connection of source components such as the CD-77
compact disk processor or a vinyl source.
Input 1 (R6) is of most consequence because first, while all 5 inputs can be connected via RCA only, Input 1 also
allows for the optional connection of XLR connectors.
Second, in other configurations where the AM-77 is used in single-channel mode, all other inputs are defeated.
Signal input is allowed only through the LEFT channel (white) of Input 1: via XLR or RCA (Please refer to
Section 4 - System Configurations
for a detailed explanation).
6. Speakon Outputs
At the rear of the AM-77 are Speakon female connectors (R2) to allow speaker cables terminated with Speakon
male connectors to be connected to the AM-77.
