I suspect you have your system wired up in such a manner that the amp is seeing too low an ohmage from your speakers. Check what the minimum ohms your amp will push and wire your speakers up so the load doesn't go below that figure.

How do you change from 4 to 8 ohm output on a phonic 1860 mixer


Stereo and bridged mode selects automatically. Stereo mode gives 4-16 ohms per side. Bridged mode is only from 8-16 ohms. This impedance match is created by the combination of speakers you use. If you link any speakers, the wiring is usually going to be in parallel because of the sockets wiring in the cabs. Any time you link 2 speakers in parallel, it cuts the impedance in half. Remember that in bridged mode, do not link 2 8 ohm sets together because this will create a 4 ohm circuit which it will not allow. This can only be done in stereo mode. It is ok to use speaker combinations of higher impedance, but never go lower as it would cause damage to the power amp.

My peavey amp pv 2600 only plays on channel A. No output on the B side


Hello,

Check the "BRIDGE" switch position, "IN" for "BRIDGE", "OUT" for "STEREO", and clean ALL back switches with a cleaning spray and then run the amp again, also check the two green lights activation at front, if they activate, then amp is certainly working, let me know further.

How do I wire up my 4subs in bridged to my peace 2600


Hi,

Please state the subs impedance, but assuming 4 subs with 8Ohm Voice Coil you CAN'T run them in parallel in Bridge Mono because this amp's minimum impedance is 4Ohm in bridge and 2Ohm stereo, maybe a series/parallel connection work, but what's the advantage to run them in Bridge mode? This amp delivers 900W per channel at 4Ohm, you can run a pair paralleled for each channel in a safe way and without the high-risk of your amp being destroyed, besides, amp power at 4Ohm Bridged is NOT recommended for continuous use, let me know your results...

Speaker daisy chaining , am I going to damage my amp etc.?


The Peavey CS4080HZ is intended to place 2,040 watts
per channel into four-Ohm-rated speaker
impedances. The "HZ" suffix is intended
to state the amplifier has a relatively high
impedance output and is optimized for no
lower than four-Ohm loads. Are you strapping in Bridged or Stereo Mode? Bridged Mono Operation
Both amplifier channels can be bridged together to make a very powerful single-channel monaural amplifier. Use
extreme caution when operating in the bridged mode; potentially lethal voltage may be present at the output
terminals. To bridge the amplifier, depress the rear panel Bridge switch to the IN position. Direct the signal to channel
A's input and connect the speakers across the hot outputs (the "+" binding posts) of channels A and B. Only channel
A's input attenuator is active while in Bridge Mono mode. Both connectors are strapped together, so either connector
can be used with a patch cable to drive the input of another amplifier.
Unlike the stereo mode, in which one side of each output is at ground, both sides are hot in bridged mode. Channel A's
side is the same polarity as its input with the minimum nominal load impedance being 4 ohms (equivalent to driving
both channels at 2 ohms) in bridged mode. Driving bridged loads of less than 4 ohms will activate the DDT
circuitry, resulting in a loss of power, and may also cause a thermal (overheating) overload.
Therefore, check the impedance of the cabs for each mode. Remember, if you connect two individual speakers in Parallel (+ to + and - to -) you cut the impedance in half. Two 8 ohm speakers in parallel now have a load of 4 ohms. Series connection + to - to + to -, will double the impedance. Two 8 ohm speakers will have a load of 16 ohms.
I have actually taken a two speaker cab with a 4 ohm impedance and opened up the back to re-do the wiring. I rechecked the impedance with a ohm meter. So yes, be careful. Whatever you do, keep the speaker lengths as short as possible. Buy really good speaker wire or if you make your own, go with 10 gauge wire.

Want to run 2 subs of 1 amp ep 4,000 in bridge mode.


You can do that but your subs will have to be monsters or you will blow them out as bridged mode will drive 2400 watts RMS into 4 ohms. Many speakers are rated in peak or program power... these are FAKE specifications. with this amp in bridged mode each of two identical speakers would have to be rated at 2400 watts program or about 3600 watts peak each to survive... When rating speakers and amps ALWAYS compare RMS values... and for safety use an amp of 80% of the RMS rating of the connected speaker or speaker system.

One chanel of my pv 2600 amp is playing very low


As a starting point clean ALL switches on the back of your amp, including the Stereo/Bridge switch then re-check functionality, good luck.

I have a peavey power amp PV2600. of late after powering, it keeps on cutting off for seconds before working again. My tech tells me it might be dying off. Please advise problem and how to fix. Thank...


"Dying off"... Time for getting a new tech... that is NOT a professional definition. It has an intermittent problem. These can be hard to catch in the act. This amp is incredibly complex in the output power amp section with many components to reach the power level they do. There is over-current protection and if you drive it too hard such as putting LARGE BASS pulses into it OR putting too many speakers on it, the over current protection will be fired and it will briefly shut down. Do this test: When the unit does this, cut the mixer driving it down by 3 to 5 DB and see if it behaves. If it does, then you are exceeding the trip point of the protection circuit. This can be ALSO caused by a failing speaker OR if the speaker is being driven too hard and the voice coil moves too far. This reduces the back EMF and current spikes. Your speakers should be rated TWICE the power capability of this amp to be safe.

Wat does the peavey 2600 do in a 2ohm stereo & a 4ohm bridge


It burns up...You are allowed no less than 4 ohms stereo or 8 ohms bridge mode.

I have 2 peavey 900 Power Amplifiers i would like to link them together was wondering what is the input wattage it can handle?? not wanting to mess anything up!


You CANNOT link the outputs of the amps. They need to drive seperate speakers.

You can tie the inputs together so they will send the same sound to their seperate speakers.

Max power for the Peavey 900 is 900 Watts RMS into a 4 ohm speaker in Bridge mode... That is enough to blow many speakers.

I think I blew out the woofer...low frequency rumbling...is that something that can be easily switched out?


The woofer would only blow if it was overloaded with too much signal. The common cause of this connecting a speaker of lower power than the amp or ohms than it. The simple way to cut out rumble is at the amp by reducing the bass, however most amps will cut all the bass and not what you want. Another way is a filter designed to cutt bass or low sounds. However your best bet is to use a Graphic Equalizer to control the tone, most have a 31khz control which will cutt the rumble you describe, but keep the wanted bass sound.
