Mackie CR-1604 Owner's Manual page 27

The channel should be set up as if it were
receiving any line input signal. This means set-
ting the proper input trim level with the fader
at unity and setting the pan control (stereo or
mono). Next you would MUTE the channel
which would send the auxiliary returns out the
ALT 3/4 Bus.
(3) Q: How do I set up a monitor or
auxiliary send master?
A: There are two ways:
1
1) Insert a mono ⁄ " cord into the auxiliary
4
(monitor) output jack and return the other
end of the cord to the line input of an unused
channel. Engage the MUTE button on the
channel which will send the signal out to the
ALT 3/4 bus. Pan the channel hard left or
right depending on which bus (3 or 4) you
want to come out of. Connect another mono
1
⁄ " cord from the corresponding ALT bus 3 or
4
4 output to the input of the monitor amplifier.
or
2) Insert a mono 1 ⁄ " cord into the auxiliary
4
(monitor) output jack and return the other
end of the cord to the line inputs on either of
the channels 1–8. Connect another mono
cord from the corresponding channel access
jack to the input of the effect device or moni-
tor amplifier. Make sure to insert the plug all
the way into the access jack on the mixer so
the signal will not go to the main L/R outputs.
Either of these 2 ways will allow you to con-
trol the overall level of the auxiliary or monitor
sends by using the channel fader as your mas-
ter. Treat it as if it were any signal but be
careful when you increase the individual chan-
nel send levels because this may eventually
clip the input stage on the master send chan-
nel. If this happens, simply turn down the trim
on the master send channel a little bit.
(4) Q: What modifications can be done to the
mixer?
Auxiliaries:
Option #1: Pre EQ, Pre Fader, Pre Mute/ALT
Option #2: Post EQ, Pre Fader, Pre Mute/ALT
Option #3: Post EQ, Post Fader, Pre Mute/ALT
(STOCK: Post EQ, Post Fader, Post Mute/ALT)
Channel Access:
Option #4: Pre EQ, Pre Fader
Option #5: Post EQ, Pre Fader
(STOCK: Post EQ, Post Fader)
(5) Q. How do I perform the modifications to my
mixer?
A: Boy, are we glad you asked! Due to
overwhelming demand we have included a
section especially for Propeller-Head-Types
on the next few pages called "MODIFICA-
TIONS-O-RAMA".
(6) Q: Can I use the Bal/Unbal Main Outputs and
Mono Output at the same time?
A: Yes! This will not degrade the signal in
any way. Remember the polarities on the main
and mono outputs when running balanced
lines (see page 14 of the Owner's Manual).
This configuration can be very useful when
an extra monitor send or a mono recording is
needed. The mono output will be the
summed output of the L/R Main Output.
It is important to remember that the Mono
Output will be the same level as the Main
Output but can be controlled at the monitor
amplifier. It can also be controlled by con-
necting the Mono Output to the line input of
an unused channel and Muted to the ALT 3/4
1
⁄ "
4
Bus and then connected to the monitor am-
plifier — this can be a little tricky because
when the main output fader levels change so
do the monitor levels.
(7) Q: Can I split the signal at the Main
Outputs with Y-cords?
A: Yes! There is more than enough signal
strength available at the Main Outputs to drive
the high impedance inputs of two devices with
no quality loss of the original signal. For ex-
ample, if you wanted to record the Main
Output to a cassette deck as well as a DAT, two
Y-cords could be used to send an identical sig-
nal to both devices. This type of configuration
could be very useful for many applications.
