Features
DC OFFSET:
The KEY500.1 automatic turn-on
mode uses DC Offset detection, which can be
selected on the end panel. Using the DC Offset
mode causes the REM wire to have +12V out for
turning on additional amplifiers. DC Offset turn-on can
only be used if speaker-level (hi-level) audio inputs are
being used. The DC offset mode detects a 3V DC
offset on the speaker wires when the source unit has
been turned on.
INPUT LEVEL:
The RCA inputs are capable of
receiving either Hi or Low-level signals from your
source unit. If the only output available from your
source unit is a Hi-Level signal, simply press in the
Input Level switch on the amplifier. Refer to the wiring
section of this manual for additional instructions.
