CARVIN 1283 Instructions

CARVIN ENGINEERING DATA
Congratulations on your selection of the 1283 loudspeaker. The 1283
vented, 300 watt 3-way speaker enclosure will exceed the power and
output of the competition and it will sound better because of its superior
design featuring a computer optimized cabinet, crossover and the Pro
Series speaker components. We realize that for a loudspeaker to sound
its finest, it must be a system of precisely aligned components. With our
matched 12" woofer, 8" midrange and titanium horn, the 1283 is an
outstanding system for a vast array of applications ranging from clubs to
outdoor use.
RECEIVING INSPECTION
INSPECT YOUR SPEAKER FOR ANY DAMAGE which may have occurred during
shipping. If any damage is found, please notify the shipping company & CARVIN.
SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to re-ship
your unit, always use the original carton and packing material. This will provide the best
possible protection during shipment. CARVIN and the shipping company are not liable
for any damage caused by improper packing.
SAVE YOUR INVOICE. It will be required for warranty service if needed in the future.
SHIPMENT SHORTAGE. If you find items missing, they may have been shipped
separately. Please allow several days for the rest of your order to arrive before inquiring.
RECORD THE SERIAL NUMBER on the enclosed warranty card or below on this
manual for your records. Keep your portion of the card and return the portion with your
name and comments to us.
WARRANTY
Parts and labor are covered for 1 year on manufacturer's defects. Warranty does not
cover burned out drivers caused by excessive power or distortion, or physical damage
caused by general use, moisture or dust. CAUTION: Distortion from power amps can
destroy drivers much faster than clean power. Contact Carvin's Customer Service at
800-854-2235 or returnsrepairs@carvin.com. Customer is responsible for shipping
charges.

SPEAKER CABLES
Use either 1/4" 16 gauge copper wire speaker cable or high-current Twist- Lok™
cables with heavy 4 conductor 12 gauge copper wire. The Carvin PH50 is
adequate for lengths up to 50' under normal use. You can DAISY-CHAIN up to one
additional speaker per cable by using the OUTPUT connector. Be sure to note the
total impedance to the amp so it is not lower than it's recommended impedance.
See Typical Loudspeaker Impedance Configurations.
SUGGESTIONS FOR OPTIMAL PERFORMANCE
Raise the enclosure to the ear level of your audience for greater coverage. To
help control feedback, keep the speakers in front of the microphone. Never direct
the microphone towards the speaker. Use a graphic EQ for further feedback
control. For greater coverage, add a second speaker system 20° to 30° off axis.
