QSC Audio S series user manual Required tools #2 Phillips screwdriver

Installation: Pre-Installation Level Setting (RAVE 160/161/188 only)

PRE-INSTALLATION PREPARATION: ANALOG AUDIO SIGNAL LEVELS (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.

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.

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.

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.
