In conjunction with the Mode Override button, the input buttons are used to
mute all
outputs (see page 10).
The input buttons are also used to enable or disable front panel security lockout
(executive mode). For more information, see page 12.
In conjunction with the volume adjust knob, the analog input (Input 5) is used to set
analog input gain level for the analog source (see page 11).

Inputs 1 and 2 accept digital signals through S/PDIF optical cables. The optical
cable supports TOSLINK or TOSLINK-compatible optical connectors that conform to
IEC-958, S/PDIF standards.

Inputs 3 and 4 accept digital signals through S/PDIF coaxial cables.
All four digital inputs accept 16-24 bits PCM audio at 32, 44.1, 48, 88.2, and 96 kHz
sample rates. They support Dolby Digital and DTS source formats.
NOTE: For digital inputs, if there is no valid clock signal at the input and no lock is
achieved, the LED associated with the source blinks twice per second.

Input 5 accepts a balanced or unbalanced analog input through a 5-pin captive
screw connector. The unit can be configured to accept:
