Modification 3 — AUX SEND

POST-EQ • POST-FADER • PRE-ALT/MUTE

This modification converts AUX Sends into

post-EQ/post-fader/pre-ALT mute Monitor

Sends. You can modify any or all of the

CR-1604’s 16 channels. NOTE: The conver-

sion affects ALL AUX Sends per channel.

1. Remove all cords from the CR-1604 and

place it facedown.

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 trace (c).

7. Add jumper wire (d). Don’t smash the

jumper down onto the circuit board. Let

it “arch above,” if possible.

vary slightly from the drawing. (Engineering sez

channel strips are like snowflakes).

8. Add 20,000Ω (20K), 1/4-watt resistor (e).

9. Replace main chassis cover and reattach

top and side screws.

10. Reconnect main chassis and pod, and

replace side screws.

11. 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 respon-

sibility in the event of improperly performed

modifications or other damages and, in such

cases, may declare warranty privileges void.
