ILoveC4 Posted October 26, 2019 Share Posted October 26, 2019 So - I’ve got a couple of 500w Episode Amps in my rack that are tied in to my distributed audio system. They’re able to be powered on and off using a 12v trigger. I know I can jump a contact over to a relay to get 12v, but I’m trying to think through how to have the relay automatically trigger when that zone is activated. I guess I could just do it via programming. Is the controller as a 12v trigger standard practice? Quote Link to comment Share on other sites More sharing options...

RAV Posted October 26, 2019 Share Posted October 26, 2019 As stated, add the control4 amp driver and make appropriate bindings. Then it's automatically powered as needed. Quote Link to comment Share on other sites More sharing options...

SMHarman Posted October 26, 2019 Share Posted October 26, 2019 This is perfect! Thanks guys. I asked the same question a few weeks ago. It also supports feedback (of power on - not the squeely type) if the amp provides it. Here is my non C4 amp working on that driver.

ILoveC4 Posted October 26, 2019 Author Share Posted October 26, 2019 Okay, so if what I'm understanding is correct, you guys are referring to the Control4 Power Amp driver, and the fact that it has a 12V trigger. I do have a Control4 Power Amp, but I also have a Matrix Amp and an audio matrix. The 2 zones that have the subwoofers and therefore the amps are connected to the Matrix Amp. And furthermore, I need 2 of them, not just 1. Is there a separate driver that does this, or is just part of that one amp driver? Assuming it IS just part of the power amp driver, is there any reason why I couldn't/shouldn't just use a contact and a relay from the controller to do this? I need 2 of them anyways...

SMHarman Posted October 26, 2019 Share Posted October 26, 2019 You need to add another instance of the pa driver. Virtual bind audio paths. And the relay. Wire the relay. Wire the audio paths. It removes any programming. The room on will turn the amp on. You are overthinking this as I was before I was given this answer. One of the beauties of control4. Removing all this baseline programming. My AMX amp has the baseline programming for the amp in the handbook. It's insane.

Cyknight Posted October 26, 2019 Share Posted October 26, 2019 Hang on there. Am I correct in assuming these are SUB amps for additional subwoofers in certain rooms? Because that changes the situation a little bit. Quote Link to comment Share on other sites More sharing options...
Cyknight Posted October 26, 2019 Share Posted October 26, 2019 You cannot use the same principal as above when using sub amps, because you can't BIND them to the rooms they are in - because there are existing binding required for the 'regular' amps. In that scenario I would just use programming. Simply put: WHEN [room] POWER_STATE_CHANGES IF [room] is on Close relay [room sub] stop Open relay [room sub] Quote Link to comment Share on other sites More sharing options...

Am I correct in assuming these are SUB amps for additional subwoofers in certain rooms? Because that changes the situation a little bit. They are sub amps, that is correct. In 2 zones, I have dual 8" in wall subs, connected to Episode 500w power amplifiers. I have the audio out from matrix split, going to the respective amps (the sub amp and the Control4 amp). These two zones happen to be connected to my Matrix amp. So it goes like this: Audio Source - Audio Matrix Input - Audio Matrix Output - SPLITTER - Control4 Matrix Amp - Speaker Wires to Room - SPLITTER - Episode 500w Amp - Speaker Wires to Subwoofer Right now, I just have the amps on all the time (for the last week). I want to connect the 12v triggers on the amps so that the amps are only powered on as needed. Does that make sense? Quote Link to comment Share on other sites More sharing options...

So in this case, I have Control4 contacts and relays, and I have the 12v trigger in on the amp. Would I make a jumper from the +12v on the contact to the com on the relay, then from the NO on the relay to the 12v trigger on the amp?

It DEPENDS on if the episode amp requires a true 12v signal, or if it generates it's own 12v (easy to test, just short the connection on the sub amp - if it stays off, it needs external 12v) sensor (or external powersupply) 12v to COM NO to 12v+ on amp sensor ground (or powersupply neg) to ground/neg on the sub amp If it supplies it's own 12v, then it's just a default relay connection - sub amp to a relay, one wire to COM, one to NO Quote Link to comment Share on other sites More sharing options...

I’m not there right now, but the amp has a 3.5mm plug out for the 12v trigger. I guess I’ll plug an IR bud in, lop the bud off and test if there’s 12V there or not.

It is quite possible the other amp has a 12v out and this is still overthinking and you just connect the sub amp to the 12v on the avr.

The subs in the theater are powered at the sub and those have a passive connection to the AVR. These are just for distributed audio. Quote Link to comment Share on other sites More sharing options...
ILoveC4 Posted October 27, 2019 Author Share Posted October 27, 2019 Well, classic case of me posting too soon and over thinking things. In digging in, the amps support audio sense. That makes it really easy! Quote Link to comment Share on other sites More sharing options...
