• Direct out with no signal interruption to
mains. Push a MONO plug into a CHANNEL
ACCESS jack until you feel it click once. In
this configuration the channel access is acting
as an independent direct out with no signal
interruption to the master.
• Direct out with signal interruption to master.
Push the plug all the way into the CHANNEL
ACCESS jack. The signal will now be inter-
rupted from the master and be available at the
direct out only. Use this mode when connect-
ing to the inputs of multi-track recorders.
• Effects Loop. A stereo plug wired as shown
in the drawing above turns the CHANNEL
ACCESS into a loop that will send and receive
to and from an external device using the same
channel access jack. Use this mode when
connecting to the inputs of multi-track
recorders.
CREATING SUB-MIXES
USING THE ALT 3/4 OUT
Surprise! The CR-1604 really has FOUR buses,
not just two! The following are working examples
of how to effectively use the flexibility of the
ALT 3/4 OUTPUT buses. In the first example, let’s
imagine that you want to create a separate drum
sub-mix. This setup is used to control the level of
all of the various channels that make up the drum
kit via two “sub master faders” (actually input
channels 15 & 16 of the mixer). For purposes of
this example, let’s assume that you have already
hooked up your drum mics or machine inputs to
Channels 1 through 5.
EXAMPLE 1
1. Now press the MUTE ALT 3/4 buttons on these
five input channels (They are no longer part of
your main mix but are now destined for the
sub-mix which in turn goes to the main mix.)
2. Next connect the rear panel ALT 3/4 outputs
back into two other channels of the CR-1604,
for example, Channels 15 and 16. These two
channels become your sub-mix level controls.
3. Pan Channel 15 HARD LEFT and Channel 16
HARD RIGHT, respectively, so that the
panning of Channels 1–5 will be reflected in
your stereo sub-mix. DO NOT engage the
mute/alt on these channels.
4. Adjust individual levels of the five drum
channels that are part of the sub-mix by using
their channel faders (1, 2, 3, 4, and 5).
5 . Adjust the pan position of each drum channel
with that channel’s PAN pot.
6. Control the overall level of this drum sub-mix
within the main mix via Channel Faders
15 and 16.
7. Add effects and EQ to the submix channels
if desired.
EXAMPLE 2
You can also create sub-mixes without tying up
additional CR-1604 channels.
1. As before, press the MUTE ALT 3/4 buttons on
the five drum Channels (1–5). These channels
are no longer part of your main mix.
2. Connect the CR-1604’s ALT 3/4 Outputs to the
LEFT and RIGHT jacks of an AUX return,. In
our diagram we’ve used AUX 1, LEFT. Stereo
AUX RETURN 1 now controls the master drum
sub-mix level.
In either of these two setups, you can
instantly solo your sub-mix into your head-
phones (or monitor speakers if they are
connected to the headphone output) by
pressing the CR-1604’s ALT/PREVIEW but-
ton or soloing the submaster channels.
