When this button is depressed, power to the unit
will be switched on and the switch will light up.
When depressed again, power is turned off.
₪ Due to the action of the muting relay, no
sound will be heard for several seconds after
switching on the power. This prevents any
transient switching noises from reaching the
speakers.
W Be sure to turn down the VOLUME control
on the control amplifier to minimum before
turning on the POWER switch to guard the
speakers against any sudden loud program
sounds produced after the muting relay time.

These two push-button switches govern the two
speaker terminals A and B. When depressed, the
speaker set connected to the respective terminal
will be connected and the switch will light up.
Depressing the switch again will disconnect the
speakers.
When using both terminals at the same time,
refer to "Speaker Connections" (p. 7) regarding
speaker impedance.
The SPEAKER switches should be turned off
when changing the connection of the speaker
cords, and they can be used in other cases, such
as changing program sources etc., as well.

@ PEAK OUTPUT LEVEL
(PEAK and OVERLOAD INDICATOR)
These peak indicators provide visual indication of
the left and right output levels. They cover a range
of 0.002W to 400W (89) (—50dB to 3dB).
Note: Also that the meters are calibrated accu-
rately for output power into standard 2
speakers, but that corrections must be
applied if speakers with different imped-
ance are used.
Clipping (at about 2% THD) is indicated for the
left and right outputs separately by the OVER-
LOAD indicators. When these light up, turn down
the input level by using the LEVEL controls on
the rear panel.
