unpacking
Upon unpacking, inspect the amplifier. If you find any damage, notify your supplier
immediately. Only the consignee may institute a claim with the carrier for damage
incurred during shipping. Be sure to save the carton and all packing materials. Should
you ever need to ship the unit back to Crest Performance, one of its offices, service
centers or the supplier, use only the original factory packing. If the shipping carton is
unavailable, contact Crest to obtain a replacement.
mounting
CPX Series amplifiers will mount in standard 19" racks. Rear mounting ears are also
provided for additional support, which is recommended in non-permanent installations
like mobile or touring sound systems.
connecting power
CPX Series amplifier power requirements are rated at 1/8 t power (typical music
conditions) and 1/3 r power (extreme music conditions). The maximum power cur-
rent draw rating is limited only by the front panel circuit breaker. Consult the speci-
fications in the Appendices section for figures on the current that each amplifier will
demand. Make sure the mains voltage is correct and is the same as that printed on
the rear of the amplifier. Damage caused by connecting the amplifier to improper AC
voltage is not covered by any warranty. Unless otherwise specified when ordered,
Crest amplifiers shipped to customers are configured as follows:
Option 1
North America 120VAC / 60 Hz
Option 2
Europe, Asia
230/240VAC / 50 Hz
Option 3
Australia
