AC POWER INLET
The AC POWER INLET contains an AC power receptacle (IEC
standard) and a fuse holder. Securely connect the AC power cable
here. When replacing the fuse, be sure to use the same type and
value specified on the marking label.
➋
MARKING LABEL
The MARKING LABEL is located under the power inlet. It describes
AC main voltage, power consumption, fuse type and value. Make
sure you check this label carefully before the installation.
Remarks: The AMP-51R incorporates an AC voltage sensing circuit
that detects incoming AC voltage and its according DC output to
automatically help select the AC transformer primary inputs, during
the start-up and when it’s running.
This ensures the best performance at any given AC condition, but if
the AC voltage is either too low (less than 10%) or too high (higher
than 5%), the AMP-51R’s protection circuit will automatically turn off
the amplifier.
➌
LOUDSPEAKER OUTPUT
When playing in the stereo mode, you can connect a pair of loud-
speaker cables to the connectors according to + and – markings.
When playing in mono mode (with two AMP-51Rs), the right channel’s
+ becomes its mono + output and the left channel’s + becomes it
mono – output. Be careful not to touch and make contacts between
any of these connectors during the installation, as this would pose a
risk of damaging the amplifier and the loudspeakers.
