Foldback Control (FB)
The Foldback c o n t r o l deter-
mines the level of signal assign-
ed to the foldback mixing buss,
thus s e t t i n g t h e level of t h a t
channel in t h e on-stage m o n i t o r
mix.
High Equalizer Control
(HIGH EQ)
The high EQ control alters the
high f r e q u e n c y response of t h e
i n p u t channel, providing ±13dB
at 10kHz, and ±15dBat 20kHz of
c o n t i n u o u s l y variable a c t i v e
shelving e q u a l i z a t i o n . The "0"
detented position provides f l a t
audio response.
Middle Equalizer Control
(MID EQ)
The mid EQ c o n t r o l provides
±15dB of c o n t i n u o u s l y v a r i a b l e
active peaking e q u a l i z a t i o n at
2kHz. and has a flat audio re-
sponse when set t o t h e "0"
d e t e n t e d position.
Low Equalizer Control
(LOW EQ)
The low EQ c o n t r o l provides
±13dB at l00Hz and ±15dB at
50Hz (of c o n t i n u o u s l y v a r i a b l e
a c t i v e
shelving e q u a l i z a t i o n .
The "0" detented position pro-
vides f l a t audio response.
Reverb/Effects Control
(REV/EFF)
This c o n t r o l d e t e r m i n e s t h e ?
level of signal assigned t o the re-
verb effects buss. R o t a t i n g t h e
c o n t r o l clockwise increases t h e
a m o u n t of reverb e f f e c t in t h a t
c h a n n e l .
Low Impedance Connectors
(LOW Z)
The XLR connectors are low im-
pedance, e l e c t r o n i c a l l y balanced
i n p u t s w i t h an i n p u t impedance
of 1k ohms.
Peak Indicator (PEAK)
The peak i n d i c a t o r l i g h t s when
t h e pre or post EQ signal level
reaches 3dB below c l i p p i n g ,
g i v i n g a v i s u a l reference for
o p t i m u m s e t t i n g of t h e t r i m con-
t r o l .
High Impedance Connectors
(HIGH Z)
These c o n n e c t o r s are u n b a l a n c -
ed, s t a n d a r d 1/4" phone j a c k s
w i t h an i n p u t impedance? of 50k
ohms, and an i n p u t level of
—35dB when t h e t r i m c o n t r o l is
set t o "10". When a plug is i n s e r t -
ed i n t o t h e high —Z i n p u t , t h e cor-
r e s p o n d i n g XLR c o n n e c t o r is
a u t o m a t i c a l l y s w i t c h e d o u t of
t h e i n p u t c i r c u i t r y .
Input Trim Control (TRIM)
The i n p u t t r i m a d j u s t s the gain
of t h e head-amp stage of t h e as-
sociated channel, providing 39
dB of gain c o n t r o l . When t h e
t r i m c o n t r o l is set t o t h e "10"
p o s i t i o n ,
t h e n o m i n a l i n p u t
levels of t h e low-Z and high-Z
i n p u t s are — 55dB and —35dB re-
s p e c t i v e l y . At t h e "0" p o s i t i o n
t h e levels are -16dB and +4dB.
The t r i m of each channel should
be a d j u s t e d so t h a t t h e peak LED
j u s t begins to l i g h t , or only
flashes occasionally. This will
ensure lowest d i s t o r t i o n levels
and o p t i m u m signal t o noise
ratio.
Recording pan Pot
(REC PAN)
This c o n t r o l assigns t h e record-
ing signal from each channel to
t h e recording L and R m i x i n g
busses. At t h e c enter position,
t h e pan pot r o u t e s t h e signal
equally t o t h e L and R mixing
busses. Panning from one side to
t h e o t h e r g r a d u a l l y assigns t h e
i n p u t signal to e i t h e r the record-
ing L or R m i x i n g bus exclusive-
ly!
Recording Level J Control
(REC LEVEL)
This control a d j u s t s the level of
signal assigned t o t h e tape deck
v i a t h e recording pan pot and
stereo L and R recording busses.
R o t a t i n g t h e c o n t r o l clockwise
increases t h e a m o u n t of signal
assigned t o t h e recording L and R
busses and t h u s the level of t h a t
i n p u t in t h e "recording mix."
Input Level Control
(INPUT LEVEL)
The l e v e l c o n t r o l provides con-
t i n u o u s l y v a r i a b l e a d j u s t m e n t
of t h e c h a n n e l o u t p u t to t h e
program m i x i n g buss, t h u s de-
t e r m i n i n g
t h e level of t h a t
c h a n n e l in t h e m a i n sound
s y s t e m m i x . Since t h e reverb/
e f f e c t s signal is "post" t h i s con-
trol, an increase in t h e level of t h e
c h a n n e l ' s o u t p u t w i l l also result
in a corresponding increase in
he reverb e f f e c t of t h a t channel.
The n o m i n a l level of t h e i n p u t
level c o n t r o l is at t h e "10" posi-
tion.
