4. MIXER INPUT SECTION.
Each channel shall include 1
rotary Trim 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 (Pre-
Fader 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 Trim 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
indicate a solo condition.
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 CONFIGURA-
TION. The mixer shall be
made of steel, painted dark
gray with light gray graphics.
The mixer’s dimensions
shall be 3.3" (84mm) in
height, 11.8" (300mm) in
width and 11.2" (284mm)
in depth, as viewed hori-
zontally. The mixer shall
weigh 6 lbs, 8 oz (14.3 kg).
Optional rack-mount
brackets shall allow the
mixer to be mounted in a
rack system, with either the
chassis top or the control
knobs’ tops to be flush with
the rack rail.
8. SPECIFICATIONS. In
addition to specifications
already cited, the mixer
shall meet or exceed the
following specifications:
Frequency response:
microphone input to any
output, 20Hz to 60kHz,
+0dB/–1dB; Total Har-
monic Distortion (THD):
any input to any output,
+14dBu, less than 0.005%;
Equivalent Input Noise
(EIN): microphone input to
insert send, –129.5dBm:
Common Mode Rejection
(CMR): microphone input
to insert send, maximum
gain, 1kHz, –85dB; Typical
Main Output noise: all
channels assigned, channels
1 and 3 panned left, chan-
nels 2 and 4 panned right,

control down, –85dBu;
channel Mute engaged,
–84dBu; channel Gain
control down, –83dBu;
Input impedance: micro-
phones input, 1.3 kilohms;
channel Insert return, 2.5
kilohms; all other inputs,
greater than 10 kilohms;
Output impedance: Tape
Out, 1.1 kilohms; all other
outputs, 120 ohms.
The mixer shall be a Mackie
Designs MicroSeries
1202-VLZ, and shall alterna-
tively be referred to as an
MS1202-VLZ.
Because Mackie Designs
constantly endeavors to
improve its products with
