Modification 4 — Channel Insert
PRE-EQ • PRE-FADER • PRE-ALT/MUTE
This modification moves the CR-1604’s
Channel Access points to pre-EQ/pre-fader.
You can modify any or all of the CR-1604’s first
8 channels.
WARNING: This is an Advanced
Deadly, Expert Level Modification. Don’t try
this one at home!
1. Follow steps 1 through 5 at the bottom
of page 31.
2. Cut traces as shown at points (a), (b)
and (c) in the upper drawing at left.
3. Add jumpers (d) & (e). Don’t smash the
jumper down onto the circuit board. Let
it “arch” above.
4. Add a 22-microfarad/25-volt electrolytic
capacitor as shown (f) — polarity
doesn’t matter. You will need to solder a
wire onto one or both ends.
5. Follow steps 9 to 11 at the bottom of
page 31.
Any internal modification of the CR-1604
must be performed by a competent electronic
technician. Mackie Designs accepts no re-
sponsibility in the event of improperly
performed modifications or other damages
and, in such cases, may declare warranty
privileges void.
* Note: Traces on different channels may
vary slightly from the drawing. (Engineering
sez channel strips are like snowflakes).
