If your 2100ES has a selectable INPUT AND OUTPUT and if you're intending to send all signal to the power amp, i.e. not bi-wiring or using the 2100ES to run mid-range or treble then you simply send Left & Right audio (White & Red cable) from a 2100ES output, probably AUX OUT ( it doesn't really matter apart from Phono on some units) straight to the power amp on AUX IN.
We should be just dealing with audio here, so connect the NAD audio output to CD or DVD IN. Select CD or DVD IN on 2100ES input switch and switch output to AUX OUT (whatever you decided goes to the power amp) on the 2100ES. Turn power amp to AUX IN and it will now get an audio signal from the 2100ES for amplification.
Speakers connect to the power amp as a normal amp, so pos and neg etc. The 2100ES now only acts as a signal feed, the power amp does all the work.
So, summary - switch on the NAD, press play - video goes separately and audio goes to the 2100ES. Turn 2100ES to INPUT for NAD. Turn 2100ES to OUTPUT allocated for power amp. Turn INPUT on power amp to allocation for 2100ES.

I have seen the higher power cb's fry the fm front end sectioon of the tuner section....did you try to put it on an aux input?....the click you hear is the amp protection relay and it sounds like it is working ok....if it were the output side of the power amp, then the relay wouldn't click after power up...it is probably the front end...this is the entire fm tuning section usually contained inside a metal box near where the antenna comes in
I don't think you can. The port will be for a powered subwoofer. However you simply connect the one or both main speaker channels via your sub speaker terminals and the main left or right (or both) speakers to the other terminals on your subwoofer. It all depends on how many speaker terminals there is on the sub. If there are two- one input & one output- connect just the right main speaker etc.
Remember the the speaker out of the amp go to the imput of the sub. And the sub outputs go the loudspeaker.
You can pull the Left and Right stereo program from either MD/Tape or Video 2 Audio OUTputs. Run a pair of RCA cables to the Active EQ's Line IN; then the EQ's Line OUT to the Cavalier's Line IN.
If the Tape output you're borrowing the program from is already connected to something, use RCA-cable splitters.
Remember to NEVER activate the monitor for that Tape function during playback of any digital audio source - it disables the digital input; or if the 901's are being used - it will remove the signal to the Cavalier.
Now if you wanted to use the 901's in your movie listening this will work with two limitations
Your receiver doesn't have preamp outputs for Front Left and Right out so you'd be extracting only the mixed-down 2-channel version of whatever the Sony is processing.
You'll have to manually control the Cavalier's volume because the pre-out you're using is BEFORE the Sony's volume control.
It might still be an improvement over what you have now.
There could be a number of issues wrong with this unit. If you have removed all inputs and speaker outputs and the unit still goes into protect you could either have a problem with the switching power supply or a shorted output stage. Both would require a trained technician to troubleshoot and repair.
protection is designed to protect the output transistors from, shorted speaker wires, shorted speakers, too low speaker impediance,make sure the amp is well ventilated.
turn the amp off for 1 to 2 hours to allow thermal reset if this fails most likley some internal damage has occured and the unit will need to be serviced
Connect a sub cable to the amps sub OUTPUT then to the sub input turn the volume up half way on the sub then go to the amp setup menu and make sure the sub is switched on then set the cross over to suit your speakers,if your not sure set to 80hrtz.
The easiest solution to use your subwoofer is to buy an amp for it. Any old stereo receiver from a garage sale will probably do just fine.
Connect the mono RCA subwoofer output from your Sony with a 1xRCA-to-2xRCA splitter to both the left and right input of the cheap reciever's tape or aux input
connect both speaker outputs of the cheap reciever to the speaker input on your subwoofer. make sure both black (-) outputs on the reciever connect to the black input on the sub, and the red outputs (+) on the reciever are both connected to the red input on the subwoofer.
make sure the cheap receiver's volume is all the way down. turn your Sony up to about the loudest you'll listen to it. turn up the subwoofer amp until it's loud enough to sound good.
leave the subwoofer amp alone, the Sony volume will all you ever need to touch from now on.
You can even now turn off your subwoofer / adjust the volume easily now!
I have experienced a similar problem with my Sony STR-GX57ES and took it to a certified tech only to find it needed the power supply replaced. I opted to hunt down a compatible power supply but have been unsucessful thus far. That being said I picked up an STR-D665 for next to nothing and found the power supplies to be quite different (you would hope so any, with the ES meaning Elivated Standard and all) but with the D665 working flawlessly I'd rather have something working than nothing. Good luck!
