REAR CONNECT PLATE
(non-powered speakers) - Use either 1/4” or
Speakon™ cables for connecting to the power amp and daisy chaining to an addi-
tional speaker. For high powered applications, use Speakon™ cables only.
SUGGESTIONS FOR OPTIMAL PERFORMANCE
To help control feed-
back, use a graphic equalizer. Keep the speakers in front of the microphone. Never direct
the microphone towards the speaker. For greater coverage, add additional speakers.
Doubling the speakers adds four times the acoustical power which is more advantagious
than increasing power.
SPEAKER CABLES
Use either Carvin’s PH50 speaker cable for up to 50’ or high-
current 12GA Speakon™ cables for lengths up to 150’. 18GA cables are not
recomended. You can DAISY-CHAIN up to one additional speaker per cable by using
the OUTPUT connector. Be sure the total impedance to the amp is not lower than the
amp’s minimum impedance.
