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.
REAR CONNECT PLATE
Two standard 1/4” phone jacks and two Twist Lok™ connectors are featured.

INSTRUCTIONS
1283
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.
