This is kind of an ambiuous question. Are you looking for barrier strip inputs and outputs? Are you looking for 70V output lines? Or are you looking for a standard 1/4" TRS input with either 1/4" or speakon outputs? If you can describe your application requirements, I can provide you with a recommendation.

Thanks,
Dan

Am a technician, i havent dealt with crest sound before. my client's amp has lit the clip light, control light but not the signal light. initially it was ok but all of a sudden, they went to operate it and...


The signal light is triggered by the presence of an audio signal on the input side and should be visible. With the clip light on without any input signal, suggests a problem in the front end. This is not an amp to be worked on without a schematic. Try getting the prints for this from Crest (Peavey owns them now).

How to activate 70v line of crest audio cki 800v


First of all the 70 volt line is used when we are dragging long lengths of speaker wires. hence to counter the drop we use a high voltage line brring it further down without any remarkable drop and use a step down matching transformer to power the speaker according to the impedance of the speaker to the secondary of the transformer. Connect the 70 volt to the 70 volt output in the amplifier. Now connect the other end of the wires tto the primary of the 70 volt transformer. Use the secondary output to connect to the speaker using the tap most suitable..2, 4,6,8 ohms . Check the phasing when you connect or reverse if the bass quality is less.
Hope this helps. Good day

Every time I turn the amp on it shuts its self off.


disconnect all speakers and test if the problem corrected you will have a problem in your speakers(either wire or speaker itself)-try to connect the speakers one by one until you find the bad one and change it--if all above does not work send your amp to service center near you

No power


These amps are very compact and are not the easiest to work on. If you are not experienced at repair, I would not recommend you start here. Where are you located?
