INSTALLATION: COOLING & AC MAINS REQUIREMENTS
Fan Cooling
The CX168 amplifier draws cool air into the rear of the amplifier and exhausts hot air from the front. This is done so the equipment in the rack stays as cool as possible. This method of cooling gives the operator “direct” air tempera- ture feedback at the front of the rack, where it is the most convenient. The front panel’s temperature indicates “how hard” the amplifier is working.
The fan varies speed automatically to maintain safe internal temperatures and minimize noise. Keep the front and rear vents clear to allow full air flow.
Air flow in QSC amplifiers
Do not obstruct the front or rear air vents! Make sure that plenty of cool air can enter the rack, especially if there are other units which exhaust hot air into it.
AC Mains Connection
The correct AC line voltage is shown on the serial number label. Make sure the AC mains is the correct voltage. Connecting to the wrong line voltage is dangerous and may damage the amplifier.
Connect the AC line cord by orienting the IEC plug correctly and pushing the plug firmly into the IEC receptacle. It should seat tightly. It can only be inserted when it is properly oriented.
Use the cord supplied with the amplifier, or an equivalent. Insure that the wire gauge of the cord is #14AWG. Use of #16 or #18 AWG can be dangerous and is not recommended.
Use the best possible connection to the AC power source. Avoid extension cords as they will cause some voltage drop between the AC source and you amplifier. If the use of an extension cord is required, ensure that it is the shortest length possible and is at least #14 AWG. Ensure that all grounding connec- tions are maintained.
NOTE: Excessive length or inadequate gauge may result in short muting episodes if all channels are driven to full power.
The correct AC line voltage is shown on the serial number label.
Connecting to the wrong line voltage is dangerous and may damage the amplifier or constitute the risk of electric shock. Verify the correct AC line voltage by checking the specification printed on the serial number label on the rear panel.
