PATCHBAY FEATURES

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 MKII mixer is equipped with rugged,
low noise, phantom-powered microphone pre-
amplifi ers, providing up to 50 dB of crystal-clear
amplifi cation. Their balanced circuitry rejects all
manner of extraneous interference. Professional
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
fi lters. The send is low-impedance (150 ohms),
capable of driving any line-level device. The
return is high-impedance (10k ohms) and can
be driven by almost any device.

These unbalanced jacks are confi gured thusly:
tip
This plug connects to one of the
mixer's Channel Insert jacks.
Tip = Send (to effects device input)
Ring = Return (from effects device output)
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 de-
vices, these jacks can also be used as channel
direct outputs; post-GAIN, post-LOW CUT, and
pre-EQ. Here are three ways you can use the
channel INSERT jacks:
(TIP = SEND to effect, RING = RETURN from effects)
