INPUT SENSITIVITY (1)
Maximum luput ksud (minimum
sensitivity rating) is achieved at the
fuJI clockwise setting, A setting of
le£s than full dockwiee will yield
lower system noise atthee^epense of
headroom. Cslihratinn indicates
sensilivjiy m volw/dBV necessary
to attain full available output
OPERATION NOTBr
The input sensiilvit.v rating of a
power amplifier is the voltage level
req uired to dri ve the eun plificr W ful I
output. Calibration in dBV allows
the mixer operator to ‘'monitor” the
power amplifier status by observing
the dRV level of the mixer l.RD
arrays (on mixers so equipped)
LKI) LEVEL IN LOCATOR (2)
A mlihrated LEI) array is provided
to visually indicate both the power
utilized (in percent^e) and head-
room remaining (in dB).
The bottom L£D is illuminated
whenever AC powor is applied as a
pilot indicator.
DDT* COMPRESSION
Each of the two internal p^wer
amplifiers is equipped with Pea-
vey’s DDT"* CcimpTession (U.S.
Patent 4318,003). The DDT circuits
will automatically engage to pre¬
vent dipping distortion mthin the
power ampliPera.
DDT~ ACTIVE LED (3)

OPERATION NOTE:
It is D orm al for the DDT' LBD<a) lo
flash occasionally during ampUCec
operation. If the LED(s} remain on
continuously, additional headroom
is needed. In sooie cases, this may
mean that the particular applica¬
tion requires a more powerful ara-
plifier.
