Unlike any other 16-channel compact mixer, the
CR-1604 is part of a mixing
system. The enhancements
presented here give you
unprecedented flexibility in
tailoring a mixer to a job.
Conversely, you need only
specify what is required for
a project without adding
costs for extraneous features that won’t be used.
Then, at any time in the
future, the basic CR-1604
can be expanded, as the
users’ needs change.
XLR10 EXPANDER
The XLR10
adds ten additional
discrete, studio-grade phantom-powered mic preamps
to the CR-1604 16-channel
Mic/Line Mixer for a total of
16 mic inputs.
The XLR10 module
mounts directly to the bottom of the CR-1604 Input/
Output Pod and becomes
an integral part of the
mixer itself. Installation
requires just a few minutes
and a screwdriver. Electronic connections are via
an integral ribbon cable
connector already inside
the CR-1604.
The XLR1 0’s preamps use
the same exceptionally high-
XLR10 docking to CR-1604
quality design that has distinguished the CR-1604 mixer.
In creating both units, we
have developed a rigorous
definition of what a Mic
Preamp should be, based on
the technical specifications
that PA, permanent install
and recording studio applications require of larger boards.
Instead of simple, two-
transistor op-amp
combinations
found in most
other small
mixers, the
XLR10
preamp uses
four conjugatepair transistors with
large-emitter geometry to
reduce distortion at all levels
and deliver extremely low
noise (our published specs
of –129.5 dBm E.I.N. @1 50
ohms, bandwidth of 10Hz to
300kHz and 0.001 % distortion are real and verifiable).

At any gain, both the XLR10
ROTOPOD BRACKET
and CR-1604 mic preamps
deliver the additional headroom and low noise floor
that set professional mixers
apart from semi-pro products: You can handle
acoustical as well as electronic events — from a
podium-pounding orator to
a timid choir hundreds of
feet away across a huge auditorium — with sonic fidelity
and without input overload.
When the XLR10 is combined with the CR-1604, the
added mic inputs can be used
by themselves or, if you’re
starved for inputs, both mic
and line inputs can be used
simultaneously, effectively
adding 16 more total inputs.
The XLR10’s mic preamps
have +48V phantom power
with switch. The XLR10 may
be added to the CR-1604 in
any of the mixer’s possible
configurations including jacks
to top, jacks to front (with
the RotoPod bracket set) or
jacks to back.
MIXERMIXER
The MixerMixer is a combiner that mixes the outputs
from up to three mixers so
they can be used as if they
were one large mixer.
Previously, combining the
outputs of two or more mixers has always been a
difficult task. At best, you
could combine main
outputs by “cascading”
which meant giving up two
inputs on one of the mixers and totally losing
combined AUX sends or
headphone monitoring
functions on all mixers.
mains, AUX and headphone outputs from THREE 16-ch. mixers
The MixerMixer solves this
problem, combining all outputs from up to three mixers
and providing a new set of
combined outputs. For example, three Mackie Designs
CR-1604’s and a MixerMixer
provide 48 line inputs (or 30
line inputs and 18 mic
inputs, 12 stereo effects
returns, 24 direct outs and 3
stereo or 6 mono sub-masters! By adding Mackie’s
XLR10 Mic Input Expanders,
mic inputs can be added as
required in groups of ten.
Since all combining is at
unity gain, no level or head
room is lost — and no
additional noise

Mixer’s noise level is so low

The MixerMixer is designed for tabletop use or,
because it’s just 1.65" thick,
can easily be bolted to the
inside surface of a rack.

CordPack for the
MixerMixer
Connecting all the outputs
and AUXes of three 1 6-channel mixers requires a lot of
patch cords. So we offer an
economical solution: A package of 36 mono and 3 stereo
cables, which provides all
patch cords needed to connect up to three CR-1604’s to
a MixerMixer. T hese are
high quality, low-capacitance cables with molded
construction, plated contact surfaces, flexible
insulation and differentcolored ends to make
identifying inputs and outputs easy.
Contents of Mackie Cordpack
By adding Mackie’s
optional Remote Fader, the
user can control the main
output level of all mixers
that are plugged into the
MixerMixer. With the
Remote Fader, existing master output sliders become
sub-masters. Pan controls
assign each channel to the
appropriate output submaster, then the Fader sets
overall output level.
The MixerMixer’s
optional Remote Fader
comes with its own 6-ft
DIN-plug-terminated connecting cable. The Fader
can be bolted to the side
of a CR-1604, handheld,
set on a flat surface or
semi-permanently
mounted with doublebacked or hook-and-loop
tape (not included).
The Remote Fader is activated by a switch set into
the MixerMixer’s front
panel, right alongside of the
DIN plug hole. It’s recessed
for security, so the user
must deliberately insert a
pencil (or non-conductive
pen) through the small
hole to depress the switch.
MixerMixers are shipped
from the factory with the
switch in the “remote-off”
position.
The Mackie Designs
RotoPod is a steel bracket/
rack combination that
supports the CR-1604
16-channel Mic/Line Mixer’s
jack panel so the connectors
can be on the same plane
as the main controls.
Adding the RotoPod
converts the CR-1604 from
a 7-rack-space mixer with
CR-1604 in RotoPod configuration
rear-facing jack panel to a
10-rack-space configuration
with front-facing jack panel.
Actually, the mixer in
this form is designed to
take up slightly less than
10 rack spaces, allowing
room for cables to pass
through to the back of the
rack (see Dimensions
diagrams on next page).
The rack ears provided
in the RotoPod kit are
designed to provide either
flush mounting, or recessed
mounting for protection of
controls and addition of a
security cover.
All necessary hardware
is provided. The conversion
takes a matter of minutes
and entails no electrical
connections.
The XLR10 Mic Preamp
Expander module may
also be attached when the
RotoPod conversion kit has
been installed.
