Carvin 1542 manual Typical Loudspeaker Impedance Configurations, Speakon & 1/4 inputs

NON-POWERED MODELS

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.

742	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
PRO SOUND REINFORCEMENT	the OUTPUT connector. Be sure the total impedance to the amp is not lower than the
IMPEDANCE: 8 Ohms	amp’s minimum impedance.
