All 8•Bus preamps use
conjugate-pair, large-emitter-
geometry transistors instead of
off-the-shelf integrated circuits.
At any gain setting, you get the
additional headroom and ultra-
low noise previously only found
in far more expensive consoles.
They can handle virtually any
live source — including scream-
ing singers and loud drum kits
— without overload.
The 8•Bus channel strip
The 8•Bus input channels'
physical layout and features are
detailed on the next pages of this
product information sheet. Note
that, although each channel strip
is relatively dense, all controls are
easily accessible. Knobs are large
enough — and sufficiently far
apart — for even the largest fin-
gers. Markings are legible, even
in low-light situations.
The four-band EQ section is
placed lower on the strip than
the AUX sends for easy access
during sessions. Within the EQ
section, the high and low shelv-
ing controls have been placed
next to MIX-B, since their op-
eration can be transferred to
the monitor section. A sharp Hi
pass filter is included for PA
applications.
Within the MIX-B monitor
section, is a Source switch. In
the Channel (down) position,
MIX-B is connected to the
same point in the circuit as the
channel fader input. It provides
a second, independent stereo
mix from the main channel
signal that is handy for broad-
cast feeds, 2-track recording,
routing to another zone in a
church or club, or an extra set
of aux sends.
8•Bus channel and bus fad-
ers are a special design that
provides true logarithmic taper.
These smooth, 100mm faders
use a complex network of addi-
tive resistive elements that
combine at various points
6 STEREO AUX RETURNS
. All have 20dB
gain, Solo and can be used in stereo &
mono. 1 & 2 are pannable & bussable.
3 & 4 are assignable to the phones for
“wet” monitoring.
6 AUX SENDS
with Solo and Solo LED.
TALKBACK
assigns to all submasters,
main mix, AUX 1, AUX 2 or Phones 1 & 2.
SOLO
level adjust and ultra-rude LED.
MONITOR
section with separate Control
Room & Studio levels. Source selection
between L/R mix, Mix-B, Tape & External.
Can be switched to Mono.
TWO SEPARATE HEADPHONE
SECTIONS
can be used totally indepen-
dent of each other. Each features source
selection between Control Room & any
combination of AUX 3/4, AUX 5/6, Mix-B
or External source. Solo allows control
room to hear what musicians are
hearing in their headphones.
MIX B/MONITOR
section can be used as
an independent stereo out for PA
monitor mix, 2-track recording,video/
broadcast feed or assigned to L/R mix.
–40 to +10 bar graph
LED DISPLAYS
for
each sub-master & Solo/Main (with
main L/R +22dB CLIP LEDs).
EXPANSION CONSOLES
let you add
channels in banks of 24 to either the
24
•
8 or 32
•
8. Expanders have their own
internal mix amps so the main board
only “sees” one extra channel per
expansion console.
Trick
BUS SOLO
switches send odd-
numbered buses to the left speaker and
even-numbered buses to the right
speaker — unless you’ve pressed the
respective MONO L&R button. When a
bus has been mono-ed, SOLO sends the
bus to both speakers.
L MIX/R MIX
&
MONO L& R
buttons assign
buses to main L/R stereo bus.
