III.  Installation

PRE-INSTALLATION PREPARATION: ANALOG SIGNAL LEVELS (RAVE 160, 161, AND 188
ONLY)

The RAVE models which handle analog audio inputs and/or outputs require a signal level set-up to achieve

optimum performance. This configuration should be completed before rack-mounting the units. (The digital AES3

models, however, do not require any such adjustment.)

These adjustments are done internally by placing or arranging jumpers on the main circuit board. For access to

these jumpers, you must first remove the top

cover of the RAVE unit as follows.

To remove cover, first detach the AC power
cord, then remove screws from top, bottom,
and sides. The arrows in this picture point
to the 17 screw locations.

Required tools: medium Phillips screw-
driver

CAUTION: Remove the power cord
before removing the top cover.
Dangerous voltages within the
enclosure may be of sufficient

magnitude to constitute a risk of

electric shock to humans.

Then lift the rear edge of the top cover about ¼ inch, or 6
mm, and slide the cover forward about 2 inches, or 5 cm.
Lift the cover straight up to remove it from the chassis.

Re-installing the cover is the reverse of removal.

Be sure to take proper
protective measures, such as
working on an anti-static
surface and wearing a
grounding wrist strap, before
touching any circuitry
inside.
