❍ Check that your AC power supply is connected correctly.
❍ Check that the ON OFF switch on the back panel is in the ON
position.
❍ Check that the fuse on the mono power amplifier back panel
and the fuse in the unit’s power plug have not blown; see To
change the mains fuse, page 14.

balanced lead
❍ Check that the phono input is shorted, using the phono
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.
