Signal Sense On / Off
The amplifier can be enabled and disabled externally by either:
-
Using the Signal sense on the audio input,
-
The Power Link trigger signal (pin 4 in the RJ45 terminal) or
-
12V trigger input.
Signal sense On:
The music signal on Line In RCA will trigger the power amplifier when a signal is
present. When the music signal is off or muted for at least 13 minutes, the
amplifier will go into standby.
The Power Link trigger (pin 4) and the 12V trigger are disabled.
Signal sense Off:
The signal sense is disabled and the Power Link trigger (pin 4) and the 12V trigger
will now power up the amplifier when a trigger voltage is present.
Line in / PL In
The amplifier has a 2-position slide switch for input selection; either the RCA Line
in or the Power Link.
Stereo / Mono Switch
This slide switch selects between stereo or mono mixing. In stereo setting, the two
input channels (left and right) are routed to the corresponding left and right
power outputs. In Mono setting, the left and right inputs are mono mixed and the
same signal is routed to the left and right power outputs.
12V trigger input / Loop out
The amplifier has a 12V trigger input (12V trigger in), which can be used to turn
on the amplifier from a control system or AV receiver. The Signal Sense must be off
for the 12V trigger to work. The 12V trigger input is hard wired to the 12V trigger
output so the trigger signal can be used for other BeoAmp 2.
Speaker outputs
The speaker output terminals consist of a 4-pin terminal (Phoenix Contact
MSTBVA 2.5/4-G-5.08 or similar) having two output terminals, each output
terminal has a + and - terminal.
Gain Adjustment
The amplifier has a gain adjustment for adjusting for different input levels.
-
When the gain is at minimum the output is off.
-
Set the gain to mid for Power Link input. (6.5Vrms input will give max output).
-
Set the gain to max for line input. (1Vrms input will give max output).
