CHANGING THE POD TO

RACK MOUNT POSITION

It only takes about five minutes and a

Phillips-head screwdriver to change the CR-
1604’s input/output pod from tabletop to
jacks-to-back position.

1.

 Remove all cords and cables from the

mixer, including a lamp if you’ve plugged
one in.

2.

 Place the mixer gently face down on a

clean, soft surface such as a blanket or
very large dog.

3.

 Remove the four #6 screws securing the

small slotted black plate on the bottom of
the main part of the mixer. Keep track of
which screws go where.

4. 

Remove the two #8 screws on each side of

the mixer which secure the pod. Gently
pull the pod away from the main chassis.

5.

 Lift the pod over the main part of the

mixer. Replace the slotted plate but install
it turned around 180˚ with the ribbon
cables in the slot.

6

. Lower the pod back onto the slots.

7. 

Reinstall two #8 screws on each side to

secure the pod. DO NOT press hard while
inserting these screws.

8. 

Install the rack “ears” on the sides of the

mixer. DO NOT press hard while inserting
these screws.

The BNC lamp socket is no longer acces-

sible in this position.

Remove  screws here on each side.

Remove  back plate

Add screws here.

Then add rack rails

Replace  back plate

after rotating 180˚.

Thread ribbon cable

through slot

CHANGING

THE POD

JACKS TO TOP?

You can also rotate the pod so that the inputs

and outputs are on the same plane as the main
CR-1604 controls. This requires our handy dandy

RotoPod

 bracket. It comes with its own set of

extended rack rails so that the mixer can be rack
mounted in this configuration. Consult your dealer
for exciting details.
