Do we have any Audio experts on here??

I've built a cinema room/ night club in my house and have an excellent set up, but I need a bit of techno help with speakers and amps. I currently have an ONKYO tr-626 amp running BOSE 7.1 speakers and it sounds amazing, but I've just built a DJ console as I'm a dj and I'm getting a sound latency when running through the ONKYO amp. I've got Pioneer CDJ 2000's and Pioneer djm 750k mixer all running through the ONKYO amp, my question is how can I add a 2nd amp to use the same speakers as they are all fitted and no wires are accessible.
I don't use a monitor speaker, as the console is right by one of the rear speakers, just want to add a specific amp to run with the dj equipment, while still having the Onkyo amp for the cinema system. Any links to products or help would be great.

Check the AV Sync setting for the input you are using on the amp.

Most AV amps have a built in delay to allow for the video processing, but you can adjust it.

Cheers mate, yeah there is something like that, I remember adjusting tv when lips were out of sync, I'm guessing if I use bypass it may work?

Worth trying.

In an ideal world you'd be bypassing the processor in the amp completely and just using the power amp stage for your DJ gear, but that isn't an option with your particular amp unfortunately. It tends to be a feature of the more expensive amps.

How are you connecting your gear to the amp at the moment?

You might want to check the 'Pure Audio Mode' as well. Also look at using stereo output to cut down on processing.

You have a decent receiver there with the 626, but it isn't really designed for what you are trying to do sadly.

Im using RCA's out of the mixer into the audio on amp, yeah it a ok amp which does a great job with BR and films, but I know I have to use a separate sterio amp for the dj gear, hence the post. I'm looking for a switcher box or something like that so I can use same speakers, I've watched a video too about doing such thing, but not sure it's what I need to do?

Sadly you can't do what they show in that video for the same reason I mentioned earlier, your receiver doesn't allow you to get in the middle between the pre and power amp stages.

This is one of those situations where if you want to do what you are trying to do I wouldn't start with the receiver you've got :(

You can select stereo mode on your receiver to take out a lot of the sound processing, and that may help with the delay as well.

Cheers mark for advise, I may see if there is a different receiver I can get with what I need?

[Mark_T]

I wouldn't give up on what you have there just yet.

I'd be surprised if the latency was that noticeable if you set it for stereo output with no sound processing.

Yeah it is Mark, tried all different settings this morning, only one with an ok level was ( direct) but then the acoustics in the room make mixing with out a monitor hard. I could just get a powered monitor for the booth, but really want to use the system. I've ask a pal of mine in America who does big systems like function one and he's going to look what's best to do, he's come a cross this before with a club once.

Good luck then, hope he can figure out a solution.

If you stay using Onkyo, I think the lowest current model that has the pre-out connections you'd need to follow the What HiFi route is either the 828 or 838.

There are a lot of other options depending on the particular speakers you have fitted and the way the wiring is run at the moment, but hopefully your friend can go through all that with you.
