Sleeve = Common ground (connect shield
to all three sleeves)
Specialty “Y” cables, developed just for these
jacks, are widely available.
Besides being used for inserting external
devices, these jacks can also be used as chan-
nel direct outputs; post-
TRIM, post-LOW CUT,
and pre- EQ. Here are three ways you can use
the channel INSERT jacks:

At the risk of stating the obvious, this is
where you plug everything in: microphones,
line-level instruments, effects, headphones
and the ultimate destination for your sound:
PA system, tape recorder, etc.
MIC
The CFX Mixer is equipped with rugged, low
noise, phantom-powered microphone pream-
plifiers, providing up to 50 dB of crystal-clear
amplification. Their balanced circuitry rejects
all manner of extraneous interference. Profes-
sional condenser, dynamic, and ribbon mics will
all sound excellent through these XLR inputs.
You can plug in almost any kind of balanced
mic that has a standard XLR-type male mic
connector.
LINE IN
The line inputs share circuitry (but not
phantom power) with the mic preamps, and
can be driven by balanced or unbalanced
sources at almost any level. You can use these
TRS inputs for virtually any signal you’ll come
across, from –25 dBu up to +38 dBu.
INSERT
This is where you connect serial effects
such as compressors, equalizers, de-essers or
filters. The send is low-impedance (150 ohms),
capable of driving any line-level device. The re-
turn is high-impedance (10k ohms) and can be
driven by almost any device.
