accepting nominal levels
from –60dBu to +14dBu via
4 rotary T rim controls.
Phantom power shall be
available via a globally­controlled rocker-type switch.
4 balanc ed o r unbalanced
(bal/unbal) line inputs shall
be wired in parallel, using

1

/4" TRS phone jacks,

11/12: The mixer shall
include 8 bal/unbal line
inputs, forming 4 stereo
input pairs, using 1/4" TRS
phone jacks, accepting
nominal levels from –10dBV
to +22dBu. O THER INPUTS:
The mixer shall include 4 bal/
unbal Aux Return inputs,
forming two stereo pairs, using

1

/4" TRS phone jacks, accept-
ing nominal levels from
–10dBV to +2 2dBu. The mixer
shall include 1 stereo pair of
T ape In jacks, using unbal­anced RCA-type phono jacks,
accepting nominal levels from
–20dBV to +16dBu.

3. MIXER OUTPUTS. MAIN
OUTPUTS: The mixer’s Main
Output stereo pairs shall be
fitted in three ways: Using
balanced XLR-3-M-type
connectors, delivering
nominal levels from –6dBV
to +28dBu, including 1 Main
Output Level switch to
provide 30dB attenuation
(XLR outputs only); using
bal/unbal 1/4" TRS phone
jacks, delivering nominal
levels from –10dBV to
+22dBu; and using unbal­anced RCA-type phono
jacks, delivering nominal
levels from –10dBV to

2/10/98

4. MIXER INPUT SECTION.

Each channel shall include 1
rotary T rim control; 1 Low
Cut filter (HPF), providing an
18dB per octave curve
starting at 75Hz; 2 rotary Aux
Send controls, providing up
to 15dB above unity gain; 3
rotary equalization (EQ)
controls: +15dB @ 12kHz
shelving, +12dB @ 2.5kHz
peaking and +15dB @
80kHz shelving; 1 rotary Pan
control, 4dB attenuation
panned center; 1 Mute/Alt
3–4 switch, to be used as a
channel mute or to route the
signal to the alternate stereo
bus (Alt 3-4); 1 PFL (Pre­Fader Listen solo) switch;
and 1 rotary channel Gain
control, providing up to 20dB
above unity gain. Note: The
stereo channels (5/6, 7 /8,
9/10 and 11/12) shall not
include the T rim or Low Cut
controls.

5. MIXER OUTPUT SECTION.

The mixer shall have 1
rotary Main Mix control,
providing up to 10dB above
unity gain; 1 rotary Control
Room/Phones control,
providing up to 10dB above
unity gainl; 1 Source Matrix
including 3 switches to
deliver any combination of
stereo signals to the
Control Room, Phones and
Meters, including Main Mix,
Alt 3-4 and Tape, which
shall be replaced by any
solo signals resulting from
the engagement of any
channel’s PFL switch; 1
Assign to Main Mix switch
to deliver the Source Matrix
signals to the Main Mix; 2
rotary Aux Return level
controls, providing up to
20dB above unity gain; 1

rotary Aux Send 1 Master
control, providing up to
10dB above unity gain; 1
Aux Send 1 global Pre/Post
switch; 1 EFX to Monitor
switch, allowing Aux Return
1 signals to be delivered to
Aux Send 1 via the Aux
Return 2 level control; and
1 blinking red Solo LED, to

6. METERING. The mixer
shall include 1 stereo
12-segment LED meter with
points at –30, –20, –10, –7,
–4, –2, 0, +2, +4, +7, +10dB
and Clip. The source signals
for the meters shall be the
same signals selected in the
Source Matrix, and a solo
condition shall replace the
Source selection with the
soloed channel(s). The
meters shall be calibrated
so that a 0dBu signal at the
Control Room output shall
be indicated as 0dB on the
meters, ±1dB.

7. PHYSICAL CONFIGURA­TION. The mixer shall be

made of steel, painted dark
gray with light gray graphics.
The mixer’s dimensions
