@ POWER Switch
Turns the operating power on or off.
The PEAK POWER
LEVEL in-
dicators will light when the amplifier is turned on.
@ PEAK POWER LEVEL indicators
These two rows of LED indicators, calibrated in rms watts with 0 dB
equal to 10 watts, indicate the power output of each channel of the
amplifier over the range of 0.01 to 130 watts into an 8-ohm load with
accurate
reading
of
the
program
peaks.
When
connecting
speakers
with
other
than
8-ohm-impedance
loads,
indicator
readings
do not show
the actual
power
output.
For a 16-ohm
speaker, multiply the indicator reading by */z.
@ When the POWER
switch is turned on, the far left LED indicator
of each channel serves as a pilot light, even without a signal pre-
sent.
© SIGNAL PATH Switches
When
the DIRECT
switch is depressed, the bass and treble tone
control circuits are completely disconnected
from the signal path
and an absolutely flat frequency response®* is obtained, regardless
of the BASS and TREBLE contro! settings.
When
the TONE switch is depressed, the BASS and TREBLE
con-
trols work normally.
The light corresponding to the depressed switch will then come on.
* The response is still subject to the action of the LOW FILTER switch, and this must of
course
be in its OFF
position for a flat response.
