Operation
Your new CAD-308 SA hybrid power amplifier is ready for operation after the various
interconnect cables and speaker wires have been installed and the unit is plugged into
the household AC mains 120 Volt AC wall socket.
Power Rocker Switch
The power rocker switch is located at the left side on the CAD-308 SA hybrid power
amplifier front panel. The switch operates in the following manner:
OFF (Down position) Removes all AC voltages from the CAD-308 SA power supply.
ON (Up position) Turns the AC voltage to the power transformer primary on. We
recommend that the AC power switch be left in the ON position at all
times. The CAD-308 SA sounds better after an initial 100 hour burn in period
and when warmed up for _ hour in daily use.
Operate LED’s: These blue LED’s light up after the CAD-308 SA is fully warmed up and
ready to operate. The delay time is about one minute.
Output Level Meters
The dual front panel output level meters show the relative output level in watts. These
are average level meters and will respond to ‘longer time constant’ signals. We have
chosen to have average level meters since these more nearly reflect the long term
power levels that are driving your speakers.
WARNING!
MAKE NO ATTEMPT TO PUT THE AMPLIFIER INTO SERVICE WITH
THE TOP OFF OR THE CABINET OPEN. NEVER OPERATE THE CAD-
308 SA WITH THE TOP COVER REMOVED. CONTACT WITH THE
OPERATING VOLTAGES PRESENT INSIDE CAN BE FATAL!
