Thanks for that awesome review.  Very easy to read for newbies like me.  Now I am definitely looking forward to the release of the higher wattage versions.

[James Babcock]

I recently purchased one of these amps and ran it for the first time on a July 1st show. I was using it to run one Peavey PV115M 8 ohm monitor wedge. I wasn't running it loud or pushing it very hard and the DDT kept coming on and the sound out of the wedge was pumping on and off. Even just sound checking it with Ipod music was shutting it down. My mixer is an older 01V and I have that running to a PV215EQ then to the power amp.

Could it be that this amp doesn't like having just one channel driven? Or am I more than likely looking at a warranty return. Any insight is much appreciated!

Rock on,

James

How does an equally sized amp perform in the same circumstances?  My guess is that 300w. isn't enough for your needs.  What were you powering the wedge with previously?

James,
Sounds like yours needs service.

Tim,
Up to now I have been using an old Yorkville SR300 which is only rated at 110 watts for an 8ohm load. All I was running in my monitor mix was lead vocals and my vocal and nothing else. I thought the IPR1600 would be a reasonable step up from that unit as far as power output is concerned. Basically anytime I ran a signal to the IPR1600 the DDT lights came on right after the Signal light lit up. To be honest the SR300 puts out WAY more than the IPR1600 does, I am thinking my new amp has an issue. I also switched to a PV112M alone, same issue. Also connected both the 15" and the 12" wedges and tried it running that 4 ohm load with the same results. Signal light on, turn it up a bit, DDT light on, sound off. BAH! It made for an interesting first set anyways. Just unplugged the damn wedge and played and sang my parts.

For the remainder of the night I used one side of a Crown XLS202 that I usually run bridged for the bass players wedge. Set it back to stereo and had my wedge for the rest of the night. The Crown is a 200W @ 8 Ohm stereo, 600W @ 8 ohm bridged amp, it worked fine.

Marjan,

Thanks for the link, after reading it I am curious as to how you feel that relates to my problem? I must have missed something in that thread and the linked review? The 8 ohm performance in the linked article is  more that twice what my old monitor amp was capable of, and it worked fine with the same wedge.

Thanks so far guys!

Hmmmm.

If you swapped another amp, keeping the same speaker and cable, I think the amp needs to see Dr. Peavey in Meridian.

Before you box it up for a return or exchange, test it outside of gigland, though, and see if you can replicate the failure.  If so, off it goes.  If not, you possibly have an iffy 1/4" connector on a speaker cable.

[James Babcock]

Tim,

I ran it with the same speaker cable as well as swapped the cable. Same with the input cable, as well as running it from a different omni out on the 01V.

I will see what the process is here in Canada as far as warranty goes.

From all the info you provided i can only to the conclusion that you have a false unit. Can you try one more thing?
Connect the signal cable to the amp and put some signal to it without connecting the speaker. Is it behave the same way?
If it does, than you have a problem in the input stage of the amp and i would advice to send it to the local Peavey authorized service.

[James Babcock]

Marjan,

Thanks for clarifying, the amp was still turning off with no speaker load and a signal supplied to it. I had the speaker cable plugged in on the amp end, but not on the cabinet end. The reason for this was when it started cutting out it was driving me crazy coming on and off, so I unplugged the speaker to finish the set! Yuck! Haha! When I got to the rack during set break and turned on my break music I ran it to my monitor channel to see what the amp was doing. Forgetting that I had no speaker load because I had unplugged the speaker I did run signal to it and the DDT lights lit up right away. I plugged the speaker back it while the music was playing and it was pumping on and off as before.

Thanks so much for the replies guys! Now just need to get that darn trailer unloaded so I can run it through some more scenarios in the relative safety of my basement.

James
