FRONT PANEL
1. Graphic Equalizer. The graphic
equalizer section divides the audio
spectrum into 9 bands. Each band is
one octave wide and is centered on ISO
standard frequencies. Each control
provides up to 15 dB of boost or cut at
its center frequency. Each mark above
and below the center position indicates a
change of 3 dB.
NOTE: When using
the D60EQ autoformer (for 8
Ω
, 70V, or
100V output) lower frequency filters
(64Hz, 125Hz, & 250Hz) should not be
boosted (see Output Barrier Strip on
next page).
2.
Level Control. The level control
determines the amplitude of the output
signal.
3.
On Indicator. This green LED indicates
that AC power is on.
4. Signal Present Indicator. This green
LED turns on when the output signal is
greater than or equal to approximately
-20 dBu (80 mv) at the 4 ohm output.
5.
Peak Indicator. This red LED turns on
when the output signal is either
beginning to clip or is on the verge of
clipping. The level control should be
adjusted so the Peak Indicator does not
light during normal operation.
6.
Power Switch. Turns on or off the AC
power to the unit.
