accommodate 8 microphone signals: mono channels 1-8;
12 line signals: mono channels 1-8, and stereo channels
9-12. The CFX•16 mixer shall accommodate 12 micro-
phone signals: mono channels 1-12; 16 line signals:
mono channels 1-12, and stereo channels 13-16. The
CFX•20 mixer shall accommodate 16 microphone signals:
mono channels 1-16; 20 line signals: mono channels
1-16, and stereo channels 17-20. The CFX Series mixers
shall have 2 stereo pairs of Aux Return inputs, a Send/
Return channel Insert for each mic/line channel, 2 stereo
pairs of Main Mix outputs, 1 stereo pair of RCA-type Tape
Inputs, 1 stereo pair of RCA-type Tape Outputs, 1 stereo
pair of Utility outputs, 2 Aux Send outputs, 4 Submaster
outputs, and 1 stereo headphone output. The mixers shall
be fitted with 1 rocker-type Power switch, one 3-pin power
receptacle, 1 BNC socket providing 12 VDC for fitting an
external lamp (not included), 1 EFX Bypass footswitch
jack, and shall be entirely self contained.
2. MIXER INPUTS.
MONO CHANNELS: Each monaural input channel shall
have an electronically balanced microphone-level input
using XLR-3-F-type connectors, accepting nominal micro-
phone levels between –50 dBu and +4 dBu via rotary
Trim controls. 48 V phantom power shall be available via
a globally-controlled switch. Each monaural input chan-
nel shall also have an electronically balanced line level
input, accepting a nominal line-level of between –10 dBV
and +4 dBu, using 1/4" TRS phone jacks. In addition,
each monaural input channel shall include an unbalanced
insert connection using 1/4" TRS phone jacks (tip=send,
ring=return, sleeve=ground), delivering and accepting
nominal levels from –10 dBV to +4 dBu.
Each stereo input channel shall have left and right elec-
tronically balanced line-level inputs, accepting nominal
levels from –10 dBV to +4 dBu. These jacks shall be fitted
with internal switching contacts to accommodate monau-
ral configuration.
OTHER INPUTS: Each mixer shall include 4 bal/unbal
Aux Return inputs, forming two stereo pairs, using 1/4"
TRS phone jacks and accepting nominal levels from –10
dBV to +4 dBu. The mixer shall include 1 stereo pair of
Tape In jacks, using unbalanced RCA-type phono jacks,
accepting nominal levels from –10 dBV to +4 dBu.
3. MIXER OUTPUTS.
MAIN OUTPUTS: The mixer's Main Output stereo pairs
shall be fitted in three ways: Using XLR-3-M-type connec-
tors with a maximum output of +20 dBu; using bal/unbal
1/4" TRS phone jacks, delivering nominal levels from –10
dBV to +4 dBu; and using unbalanced RCA-type phono
jacks (labeled TAPE OUT) delivering nominal levels from
–10 dBV to +4 dBu.

CFX SERIES 12-, 16-, and
20-Channel Mic/Line Mixers
OTHER OUTPUTS: Each mixer shall include 1 Subwoofer
Output using an XLR-3-M-type connector that includes
a built-in 18 dB/octave 75 Hz crossover. The mixer shall
include 4 Submaster outputs, using bal/unbal 1/4" TRS
phone jacks, delivering nominal levels from –10 dBV to +4
dBu; 1 stereo pair of Utility outputs, using bal/unbal 1/4"
TRS phone jacks, delivering nominal levels from –10 dBV
to +4 dBu; 2 Aux Send outputs using bal/unbal 1/4" TRS
phone jacks, delivering nominal levels from –10 dBV to +4
dBu; 2 EFX Send outputs using bal/unbal 1/4" TRS phone
jacks, delivering nominal levels from –10 dBV to +4 dBu;
and 1 stereo Headphones output, using an unbalanced 1/
4" TRS phone jack (tip=left, ring=right, sleeve=ground).
4. MIXER INPUT SECTION. Each monaural channel shall
include 1 rotary Trim control, 1 Zero Level LED that is trig-
gered to glow when an audio signal at or above 0 dBu is
passed through the channel, Low-Cut filter (HPF) providing
an 18 dB per octave curve at 100 Hz, 2 rotary Aux Send
controls providing up to 15 dB above unity gain, 1 Pre-
Fader switch assignable to Aux Sends 1 & 2, and 2 EFX
Send controls, providing up to 15 dB above unity gain.
Each monaural channel shall include 4 rotary equalization
(EQ) controls: +15 dB fixed 12 kHz shelving gain, +15 dB
midrange peaking gain, 100 Hz-8 kHz midrange frequency,
and +15 dB fixed 80 Hz shelving. Each monaural channel
shall also include 1 rotary Pan control, 4 dB attenuation
panned center, and 1 Mute switch. Each monaural channel
shall also include 2 output Assign switches delivering the
channel's signal relative to its Pan setting to Submasters
1-2 and Submasters 3-4, 1 channel Fader providing up to
10 dB above unity gain, and 1 Pre-Fader (PFL) Solo switch.
5. MIXER OUTPUT SECTION. The mixer shall have 1 Main
Mix stereo fader providing up to 10 dB gain, 4 Submaster
mono faders, (each providing up to 10 dB gain), indepen-
dent left and right Assign to Main Mix switches for each
submaster, 1 Utility Out level rotary stereo control, provid-
ing up to 10 dB gain, and 1 Phones level rotary stereo con-
trol providing up to 10 dB gain. The mixer shall also have 1
Break switch that mutes all input channels to Main Mix, 1
