.... or at least without buying a new amp/spending a lot of money.....
Basically, I have a DJM800 on one side of the room hooked up to a pair of KRK RP8s. Works very well.
Then on the other side of my living room I have a Marantz SR7001 amp attached to some Monitor Audio BR5s. They also work like a charm for my home cinema.
What I've tried is to route the booth (or master - it makes no difference as far as I can tell) out from the DJM800 to an input on the Marantz amp, so that if I'm mixing and there are some people in my living room they can hear the sound through the cinema setup. What happens is that the sound from the Marantz amp is very very slightly delayed, causing a slappy echoey effect, a little like two tracks that don't quite have their beat locked.
The only thing I can think of doing is to put some sort of slight delay on the KRKs, however I wouldn't want to do that cos it'd affect my mixing and timing etc, and also I wouldn't know how to do it.
The marantz amp has a lip sync feature, but this delays the sound further, rather than advancing it to the point I need.
Anyone have any suggestions? I don't think this problem can be solved! |

I have the same problem trying to power 4 speakers from 2 different receivers, and I haven't found a solution yet!
What I did is switched to one receiver... you could just get some cheap passive speakers to put near your booth and run all 4 speakers from the Marantz. |

There are two possible problems here and I can't tell from your post which (or both) is affecting you.
1, The amp is taking time to process and output the signal, either intentionally (delay for surround specifications, see below) or unintentionally (just from having to process the signal etc. like with power amps in clubs)
2, Arrival time differences between the two systems. Basically the speakers in your living room are further away so it takes longer for the sound to reach you meaning there is a slight delay, manifesting as a small slappy echo.
If the problem is the first one, that amp should have a direct output option (called non surround or surround off) but that might only be for a stereo pair (not the full set of surround speakers). Most surround amps have configurable delays (usually surround modes) for the speakers to adjust arrival times for the sound coming from each (or groups of) speaker(s). You need to set this to nothing (surround off) otherwise there will be a delay. Typically the delay is something like 30 ms for rears (dolby surround etc.). Sometimes these surround settings also include delays between front and rears to mimic room types such as halls etc.
If the problem is the latter issue (2), then unless you move the dj'ing/listening position to be equidistant between the two sources then your screwed, and are not going to be able to get rid of the echo effect. Even if you do make it equidistant, if there is a processing lag difference between the two systems then you will get an echo or phasing.
Hope this helps.... |

Cheers guys.
Mr Rann - I'm going to take a look at some of the settings on the Marantz amp tonight - I'm keeping my fingers crossed that there's something I can set on the input I am using from the mixer - this sounds like the most likely way I can solve the problem.
I don't think it's acoustics - My living room is about 3 x 4 meters! |
