Modification 3&4
Modification 2 — AUX SEND
POST-EQ • PRE-FADER • PRE-ALT/MUTE
This modification converts AUX Sends into
post-EQ / pre-fader / pre-ALT/mute Monitor
Sends. You can modify AUX 2, AUX 3 and/or
AUX 4 on any or all of the CR-1604's 16 chan-
nels. Converting AUX 3 also converts AUX 5;
converting AUX 4 also converts AUX 6.
1. Remove all cords from the CR-1604 and
place it face down.
2. Remove ribbon cable plate cover (a).
Keep track of what screws go where!
3. Remove pod mounting bolts (b) and
separate pod from main chassis.
4. Remove bottom and side screws from
main chassis.
5. Remove main chassis cover and set it
aside.
6. Cut traces to selected AUX Sends (c).
7. Add jumper wires [shown as grey lines
(d) in illustration] for those AUX Sends
with cut traces. Don't smash the wires
down tight onto the circuit board. Let
them "arch" above if possible.

modifications or other damages and, in such
cases, may declare warranty privileges void.

vary slightly from the drawing. (Engineering
sez channel strips are like snowflakes).
