3.1 Power On/Off
Use the rocker ‘POWER’ switch (R6) at the rear of the CD-77 to switch mains power ON to the CD-77.
To switch the mains power OFF, press again and release. Always WAIT at least 30 seconds before switching on
again. This is to enable the OptiMains® circuit to shutdown properly.
The display will light up to indicate the unit is switched on and ready for use. This should take just under 1 minute
as the OptiMains® circuit is verifying the incoming mains and the CD processor is warming up.
3.2 Standby

switch to STANDBY mode.

ance for the next listening session. However, power to the valves will be switched off to preserve valve life.
Standby will maintain
power to the non-
