CFX.mkII SERIES
The CFX12.mkII is equipped with 8 mono mic/line channels
and 2 stereo line-in channels for a total of 12 channels (the
CFX16.mkII has 12 mic/line channels and 2 stereo channels
for a total of 16, and the CFX20.mkII has 16 mic/line
channels and 2 stereo channels for a total of 20). Beyond
that, they share the same feature set, with four subgroup
outputs, a stereo main out and a subwoofer out.
Each mono mic/line channel has an input Gain control with
45 dB of gain, a sharp 18 dB/octave, 100 Hz Low Cut filter,
a 3-band EQ with sweepable midrange, two Aux sends
with pre/post switch and two EFX sends, Pan, Mute, Solo,
assign switches, a 60mm fader and a Channel Insert jack for
connecting an external processor.
The stereo line-in channels have all the same features as
the mic/line channels except no low cut filter, an input Gain
control with 40 dB of gain, 4-band fixed frequency EQ, and
no insert jack.
There are two stereo EFX returns with EFX Return 2 being
combined with the internal EFX EMAC digital effects return.
The 32-bit EMAC digital effects processor has 16 individual
effects, two parameter controls, and a wide spatial
expander.
Other features include phantom power, a stereo tape input
and output with input level control, a Break switch to mute
everything except the tape input, Phones out, stereo Utility
Output, stereo 12-segment LED meters, BNC lamp socket,
EFX footswitch jack, TRS and XLR stereo Main Output jacks,
and a 75 Hz low-pass Subwoofer XLR Output jack.
With professional sound quality and all the right tools for
live performances—the CFX.mkII Series is the obvious choice
for small bands, solo performers and anyone who needs a
reliable compact mixer.
