Port lights come on almost immediately after power up with or without input source connected. Amp is being used to power small monitor speakers. Audio source is my laptop itunes library connected to a 12 channel Yamaha mixing board. Mixer sends signal from monitor out L/R to input jacks L/R on amp. Port lights shut down all audio when they come on right after power up. If I power off the amp and let it reset it will come on for a couple seconds, then port lights come on both channels and audio shuts down.

Looks like it takes regular home theatre speaker wire. If this is a powered speaker (like a JBL eon g2), then all you need is a passive mixer, and connect the speakers to the mixer. If this is not a powered (amplified) speaker, then you will need an amplifier to boost the sound source and drive the speakers, so you would connect the mixer to the amplifier, then the amp outs to the speakers.
Pleae check to see if you have over loaded the output with a wrong impedance . If so try to test the speakers and connect accordingly.
Next please check if the input source is bringing in poor signals with noise. try to cut off the hig and low freq to set the treble and bass in mid position. next use a ggood ground to take off any transcient voltage on the body due to any leakage in the power circuits. next you can disconnect and opne the panel and check for dry connections, loose connectors or poor filtering in signal processing or power circuits. If you notice any hum check this out. I hope this helps. Good day
Hook the signal source to the equalizer input and the equalizer output signal to one of the signal inputs on your amp. This is one way, but this way only one signal source will go through the equalizer (unless it has several signal inputs and a source selector switch).
The other way (inserting the equalizer between the preamp and the main amp) is:
If your amp has RCA connectors on the back named "preamp out" (or similar) and "power amp in" (or similar) that have slugs connecting them, remove the slugs, hook the "preamp out" signals from the amplifier unit to the signal inputs on the equalizer and outputs from the equalizer to the "power amp in" inputs on the amplifier.
Basically, what you do is that you insert the equalizer between the preamplifier section and the power amp section of the integrated amplifier so that you can still select the signal source without having to switch any signal cables (however, i can't say if your amp has got this type of "slug" connection feature between the preamp and the power amp on the rear panel, so i'm not sure which way you'll have to hook it up).
Do this, CD audio out jacks to the PRE-AMP INPUT jacks, then PRE-AMP OUT jacks to AMPLIFIER INPUTS then from AMPLIFIER to speakers, This will work similiar with any sound source unit ie. Radio Tuner, Tape deck, etc. Just think of it this way, a PRE-AMP is BEFORE the AMPLIFIER, all the AMPLIFIER is going to do is AMPLIFY the sound to your speakers, HOPE THIS HELPS!
Cables are either shorted, or deck is putting out too much power for input on amp... many new head-units will put out up to 7v on the output jacks (RCA) the amp may only want to see up to 1v will need to consult head-unit manual for adjustment of outputs.
Speaker fuses are generally fast-blow styles 250 volt glass If an amp shuts down, with speakers connected, it sounds like one of the power supply lines does NOT like what it's "seeing" . Probably output transistors bad ( or module)
There are many answers to your questions but Ill have a go with the basics...
Audio connections should be matched.... its called Frequency impedance,.... to get a signal along wires or cables (or Fibre) the Impedance of the cables and wires must be matched to the device they are connected to transfer the signal along the cables without distortion...
Manufacturers provide many sockets on the input side of amplifiers and preamplifiers to allow the consumer to connect various devices of different impedance.
They label these inputs like CD, or Tuner, or PHONO etc etc,
That means if you have a CD player it must be plugged into the CD input socket then the impedance will be correct and the sound will transfer along the CD cables correctly, without distortion..same with the Phono input etc...
You will find on the sound output to the speakers terminals are also labelled 4-6ohm, or 8-10ohm, these are the impedance expected for the coil ratings of the speakers them selves and its important to get the correct speakers to the correct out put terminals...
In your case all you have to do is follow these simple rules and all will be well....you say you have a squeeze box well there probably isnt a port labelled squeeze box so you need to experiment and try out each input port for the squeeze box to see what input gives you the correct sound output...Watch the Phono inputs as these are very sensative to input sound levels and must be treated very carefully as they have a double stage of sound amplification and as such you need to have the volume right down when connecting up the Phono inputs then increase the volume carefully after the cable connections are completed.
If you follow these rules then all will be well,,,,there is no difference if the Pre amp or Power amp is valve or transistor or FET or has IC outputs to the speaker the same impedance rules apply..just treat it as a box with input and output terminals and all the impedance will be taken care of for you...if you read the lables...
You need to connect you signal source to the Preamp inputs the out put from the Preamp connects to the power amp input then the power amp output goes to the speakers. this is a basic configuration for sound systems, there are other variations but are outside this discussion.
You say that the CD player goes well and does not shut the system down like the Live connections. This is a single input configuration...
This means that there is sound levels coming in from the live multiple connections that are too strong (Loud) for the amp to handle...
Its a good amp you have as its shutting down to protect itself instead of blowing up....
So.... set up for the live show then disconnect all but one of the live inputs and start the live session if its OK, then connect another of the live connections, and see if its OK, if it is then connect another live one connecting each one progressively until the problem occurs again...this last live connection is the one that is too loud in signal strength for the amp to handle causing the shut down...
Solution is to reduce tha signal on that last cable source to a level that stops the shut down...I remember that groups of guitar players have volume controls on each guitar and if these are set too high then this can occur....specially if they are all using the same amp without a controlled "mixer man" monitoring each input signal.
Rember the small meters on the mixing panel which have a green painted area and a red painted area the "mixer man" must keep the each meter needle in the green zone for all the inputs otherwise a shut down occurs.
Hope this helps you...
