II: BASIC INSTRUCTIONS
2.1 UNPACKING AND INSPECTION
All QSC Series One amplifiers are fully tested and inspected before they leave the factory. Despite the protective carton
and rugged amplifier design, it is possible for shipping abuse to damage the amplifier. Check for obvious carton damage
while unpacking the unit. After removing the amp from the box, rotate it in all directions to check for loose parts inside.
Please save the carton for return shipment, if required. QSC does not warranty against damage caused by sending
amplifiers back in the wrong carton.
If shipping damage is evident, notify the transportation company immediately. Only the consignee can file a claim with
the carrier for shipping damage. QSC will cooperate fully in such an event. Be sure to save the carton for the shipper to
inspect.
2.2 IMPORTANT PRECAUTIONS
2.21 The power must be OFF when making any connections. If you connect plugs with the power on, especially in dry
environments, static sparks or bad cables can cause pops or hums which can damage speakers.
2.22 When first powering up the amp, have the amplifier Gain controls all the way off, in case of defective cables or
hookups. Turn the Gain controls up gradually until normal operation is verified.
2.23 Check the AC voltage printed on the serial number label to ensure your amplifier is properly configured for the AC
voltage supplied in your area before connecting the AC plug.
CONNECTION TO A VOLTAGE SOURCE OTHER THAN THE ONE SPECIFIED WILL IMMEDIATELY DAMAGE
THE AMP, AND VOIDS THE WARRANTY.
2.24 Never connect the speaker terminals (red binding posts) for two channels together on any power amplifier. The
two channels will fight each other and possibly fail. Do not connect the speaker ground terminals (black binding
posts) to chassis or signal grounds, as the resultant ground loop could cause ultrasonic oscillations. In other words,
keep all speaker wiring separate for each channel, and separate from input wiring.
2.25 Do not remove the amplifier cover, as there are dangerous voltages inside. Do not expose to rain or moisture.
Refer all servicing to qualified personnel. The warranty will be void if the amp is tampered with by non-QSC repair
centers or personnel.
2.26 The QSC Warranty does not cover tampering by unqualified personnel, or repairs made at non-QSC repair
centers. Please call the factory for Service Center information and locations.
