Martin Audio linking two amps to run 4 subwoofers

[Kenlite79]

Hello there

 

First of all I'd like to apologise for my lack of knoledge with sound equipment, I'm an electrician who happens to have a mobile disco business so I know the real basics when it comes to connecting up a sound system.

 

I've recently been asked to do some installation work in a bar and they want me to run new speaker cable to the existing subs and another pair to another set of subs that they want to install.

 

here's the equipment list: there's 4 Martin Audio ICT 300's (300W) full range speakers running from a Citronic V12 amp

4 Martin Audio ICS 300's (400W) subwoofers running from a Citronic V9 amp

These run through the Martin Audio cross over unit of course, I have been asked to install another pair of ICS 300 subs and they are going to buy another amp to run them. Here's the killer question!! how do I interlink that second amp to run the same signal and get the full potential of the subs.

please remember I'm a novice guys so if you start talking about using the amp in paralel mode please explain in detail the actual connections from the incoming left and right channels of the mixer, if you can help me at all I'd really appreciate it many thanks. ken

Oh dear! your post got cut off in it's prime!

 

I'm second guessing you want to have 2 amplifiers with 2 speakers each, i.e. one speaker per amp output (channel). You want to send the same signal to all. Yes you can.

If you send the signal to the first amp, as you probably currently have, then you can (usually) just loop out of the first amp in to the second amp.

Many amps have a pass through on the input connectors, although they may be physically different connectors. Just don't take a speaker out to an amp input!

Althernatively, you may get away with using Y spiltters, which physically split the cable from one socket to two plugs.

 

HTH, if not just ignore me!

Ha! Just answered that in your 'incomplete' post..

I believe there is more to this.

 

The topic title states subwoofers.

 

I'm going to guess (this is fun) that the OP has the 4 ICT300's from the 1 amp and is happy with that, but was also going to get round to saying that he has 4 subs and 2 amps.

From the output on the controller do a Y split to the 2 amps for the subs.

 

You are using the correct controller for the ICT300's? They sound very muddy without.

 

Moderation: Shortly after Rob posted this, we got the original post sorted out. So no need to guess now.... sorry for spoiling the fun!

WOOOO I win...... sort of.

 

To clarify A y split from the controller outputs into the 2 amps for the subs.

I'm hoping the whole post is showing now, thanks for the quick reply guys and you nailed it ** laughs out loud **, I want to connect four ICS 300 subs where's there's only two at the moment, I've never connected multiple amps and speakers before just a simple left and right out of the mixer to an active cross over then the high and low to the inputs on the amps.

 

I can only assume the right controller is being used for the martin gear as it sounds amazing very tight base and cyrstal clear highs and LOUD!!! they just want more base around the dance floor :D

So to clarify this for my sake there is NOT parallel inputs on the amps?

Thanks for that, so the martin controller uses standard quater inch jacks and I just need to get a y splitter, wow that was easy now lets hope it all works thanks again ken

To quickly answer John I believe some amps can be switched between Stereo and Parallel input mode via dip switches but these amps are just set up in stereo with the signal being sent to both channels as normal so I'm guessing Y leads should do the job

I think what John was actually asking was whether the amp has two input connections on each channel, which are connected together in parallel. This is very common on pro amps as it allows you to connect the inputs of several amps together in a daisy chain fashion without the need for any splitters.
