OPERATING PARTS

POWER

is turned on. The power meters will be illuminated,
indicating that the power is on. The unit will become
active 3 to 6 seconds later because of the employ-
ment of a protective circuit and relay.

SPEAKERS

This switch is used to select speakers connected to the
A and B speaker terminals on the rear panel. When the
switch is set to the AIS position. both speakers con
nected to the A and 8 terminals are operated at the
same time. Speakers may be connected to the A or B
terminals only, if desired. At the OFF position of the
switch, no speakers will operate.

METER RANGE

sensitivity of the power meters in 4 steps.

120W (at Sohm load).

By pressing the button switches as shown on the turn
panel, the OdB position on the power meters represents
EDW for -6dB setting, 7.6W for -12dB setting and
0.48W for -24dB setting, respectively.

The power meters indicate the levels of left and rig»!
channel output power in dB. Power levels can be red
directly on the meters with the meter range switches
