Carvin LS1502A manual NON-POWERED Models, Typical Loudspeaker Impedance Configurations

NON-POWERED MODELS

MULTI-WAY CROSSOVER CONNECTIONS (non-powered speakers) Use either 1/4” or Speakon™ cables for connecting to the power amp and daisy chaining to an additional speaker. For high powered and biamp applications, use Speakon™ cables only.

1.1/4” inputs from power amp output (full range input only).

2.Speakon™ input from power amp (full range or biamp). Note: the Speakon pin configuration for biamping is:

1+ LF Positive / 1- LF Negative 2+ MF/HF Positive / 2- MF/HF Negative

3.Full Range/Biamp mode switch

4.Speakon™ through wired in parallel with input Speakon™.

5.1/4” through wired in parallel with 1/4” input.

SUGGESTIONS FOR OPTIMAL PERFORMANCE

•To help control feedback and to correct for venue characteristics, use a graphic EQ.

•For optimal coverage and dispersion, elevate high frequency horn above eye level.

•For optimal headroom, select an amplifier with a power capacity equal to or up to double the rated program power capacity of the loudspeaker system.

•Ensure all amplifiers are supplied and connected to properly rated AC power circuits. Underpowering amplifiers may cause premature clipping distortion.

SPEAKER CABLES Use either Carvin’s PRO50S 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 amplifier is not lower than the amplifier’s minimum impedance.
