Modification 1 — AUX SEND PRE-EQ• PRE-FADER • PRE-ALT/MUTE

This modification converts AUX Sends into pre-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.

8.Replace main chassis cover and reattach top and side screws.

9.Reconnect main chassis and pod; replace side screws.

10.Gently nudge any slack ribbon cable into the main chassis and replace ribbon cable cover.

Any internal modification of the CR-1604 must be performed by a competent electronic technician. Mackie Designs accepts no responsibility 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).
