shorting plug supplied.
The sound has cut out
The 505 Mono Power Amplifier includes a thermal shutdown,
which mutes the output if the amplifier becomes too hot.
❍ Leave the amplifier for a few minutes to cool down, and the
sound will come back on.
The 505 Mono Power Amplifier also includes a power circuit
breaker to protect the loudspeakers.
❍ Check the system for the cause of the cut out.
❍ Switch off, wait 5 seconds, then switch on to reset the power.
