PRE-INSTALLATION PREPARATION: ANALOG AUDIO SIGNAL LEVELS (RAVE 160/161/188  ONLY)
CAUTION: Detach 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.
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: #2 Phillips screwdriver.
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.
Reverse this procedure to reinstall the cover.
Be sure to take proper protective
measures, such as  working on an
antistatic surface and wearing a grounding
wrist strap, before touching any circuitry
inside.
Installation: 
Pre-Installation Level Setting (RAVE 160/161/188 only)
The RAVE models supporting analog audio inputs and/or outputs may require signal level setup to
achieve optimum performance. Level setup must be configured before rack-mounting the units. The
digital AES3 (digital audio) models do not require any adjustment. Level adjustments are made by
configuring internal jumpers on the main circuit board. For access to these jumpers, you must first
remove the top cover of the RAVE unit as follows.
NOTE: If synchronizing to an AES3 (AES/EBU) source, see page 18 for AES3 jumper settings.
