I use the crown xti 6000 for 2 double 18s pd186 for bass per channel

Send a signal from the mixer to the amp directly, seems as if you have a distorted signal from your crossover

Does the input signal to the xti 2002 amp make adifferance balanced or un?

The balanced line input will be used for long runs to eliminate noise. it is low impedance.the high impedance line (unbalanced) is ok for sort runs such as in a rack. if you were say running output from a mixer 50' away you want to use the balaced output on the board and the balanced input on the amp.

I have an elderly (but until now totally reliable) SA-620 amplifier. All of a sudden the left channel isn't working. It is the same whether you use the A or B outlets. Any ideas as to how I can fix this?

You do not mention whether you use one or several inputs on the SA620, but move the selector switch to & fro a few times to clean its contacts. Similarly, unpIug the phono plugs & replug (on Left channel). I aIso assume there is no left channel when using headphones. Also check the two thick wire links at the back are pushed in properly (take out & push back in to make sure), since these link the preamp to the power amp. All the above is done with mains power off.

On these old units, switches sometimes fail due to impurities on their contacts, so operate them all (with mains OFF) a few times to wipe the contacts clean.

It would be informative to find out if the fault is in the preamp or power amplifier section.
To do this, connect signal (eg external CD) to the TAPE 1 'PLAY' input (left) & switch front panel to TAPE 1. This bypasses the preamp section & injects the signal into the volume control. If there is still no left- hand channel, then the fault is likely to be in the power amplifier.

Only if you are technically competent, disconnect SA620 from mains, remove the SA620 lid, and with an insulated object eg a plastic screwdriver handle, tap the loudspeaker relay RL1 to release a possible sticking contact. If this does not cure the fault, then the same can be done with the unit turned on & a signal present.

If there is still no response, further fault finding in the power amp will be req'd.

I have my amplifier connected to my dj system only one speaker of the bass works wich is channel 1 channel 2 does not work and fault button keeps on blinking red?

The XTI 2k has lots of DSP options built into the front panel. If it's your intent to run the amp in bridge mono for subs be sure than you have all settings set correct for the DSP, it's very possible that channel 2 will render in-active.

This also applies in the case if you wanted to run your subs in stereo and the internal settings are set for bridged mono.

Another possibility would be if the DSP was set with a crossover. If you put a cross-over point (Low Pass Filter) on the high side of the sub, if becomes the High Pass Filter of Channel 2. Audio would pass if there was no other filter sets, but would not if you were using a crossover and then hitting the subs.

My XTi 2000 is very distorted intermintently. Sometimes the volume drops by at least half. I tap gently on he top of the amp and it comes back up to normal. I heard Crown has had some issues. What's the...

From your description, I would suspect some poor solder connections inside. If you know how to work on these, check for bad connections near the voltage regulators. That is the mode common area.

Keep blowing speakers

It sounds more like you are overdriving the speakers not clipping the amp. If the output rating for the amp is 1000W into 4 ohms, this is approximately 500W into an 8 ohm load. Your speakers are rated for 400W. If you are running the amp at full output, that is too much power for the speakers and either the speakers are warming up too much and failing or are being extruded too far and failing. Your best bet is to better match the amp/speaker setup. Crown amps have built in clipping indicators and I believe that the xti series also has a compression circuit that would prevent distortion on the output side.

To confirm my suspicions, in what manner are the speakers failing? Are they completely open or do they sound distorted?

I have two xti 2000 amp running with electrovoice speaker 600w

This is most likely to be a heat issue where the amps overheat and shut themselves off then cool down and turn back on. Please check that the amps have proper ventilation and that any air ducts are clean.

Amp cuts off

The amplifier is going into protection. This may be caused by problems with speakers or wiring, or there may be internal problems in the amplifier. Start by connecting a known good speaker with a few feet of wire, and see if it runs without shutting down. If so, check the wiring and speakers. If the problem continues, the amp should be serviced.
