ADA1500 - Trigger Cable - 06/30/19 08:03 AM

Hi Guys,

I finally pulled the trigger on the ADA1500 (3 Channel). Quick question related to triggers. Does it come with the trigger cable or do I need to purchase one?

Thanks!

You need to buy one. Careful with that thing so you don't go deaf.

Oh...I now understand the need for a 1500. laugh

Ha! Actually, I upgraded my ancient Denon AVR-3806 a couple of months ago to the Denon AVRX4400H (last years model, so I got it for only $800). Although it is rated 125WPC (instead of 120WPC which was the rating of the AVR-3806), it does not seem to have the punch of my older receiver. It's actually significantly lighter too, and gets VERY hot. So I figured now was the time to do the upgrade I wanted to do for years. The ADA1500 will power my two M80s and my VP180, and I'll let the Denon handle the 2 Surrounds, 2 Rears, and 2 Dolby Atmos speakers.

I'm curious if the punch you lack is during music, movies or both.

Both, but mostly music. LFE is handled by the 2 EP800s and they do a great job below 40 Hz, so I notice it more in music. I tried with and without Auddessy. Even the wife noticed it. She gave me the okay for the ADA1500 purchase, so it must have bothered her too.

Be sure the cable you get is mono for the trigger, stereo usually doesn't like to trigger.

Re: ADA1500 - Trigger Cable - 07/04/19 11:25 AM

Really? I heard either would work. I only have stereo, do I need to buy mono?

Re: ADA1500 - Trigger Cable - 07/04/19 12:01 PM

The answer may be called out in Axiom's manual but if not, it's a question for Axiom for sure. It's possible to design the trigger circuit to accept mono or stereo or both.

The trigger jack is stereo, but we only connect the tip and sleeve, so you can use either a mono or stereo cable. smile

Thanks Andrew! Can't wait till it arrives!

The wait is coming to an end, it shipped today.

You will finally be able to hear what the M80 is capable of; more so if you have v4. Just be careful because the 1500 can melt your M80s. Not the M100 though. I tried. smile

It can also vaporize your 180. Poof!

And liquify your cochlea. Bubbly goo!

And if you have a martial arts staff mounted in your living room, it will fall. Go bang!

Okay, now I'm scared...

I won't put it on 11. smile

Congrats SRoode limbo is almost over.

Try it at 11 isn't that the point of such power? With my 1250 I can go reference without any hint of distortion. Plus the ADA barely gets warm even with prolonged use.

Re: ADA1500 - Trigger Cable - 07/28/19 05:42 PM

I can tell you unless you are listening to flutes, the 1500 gets very hot in 2.0 feeding the 100s at full power. A class A or even A/B amp would turn into a puddle without very beefy and expensive heat sinks or less beefy sinks and active cooling.

Re: ADA1500 - Trigger Cable - 07/28/19 09:05 PM

Okay now I'm confused. How does a Class D amp get that hot? My Denon 4400 is HOT, but it's a Class A/B, driving all 9 speakers, 3 of which are the ones the ADA1500 will now power.

Re: ADA1500 - Trigger Cable - 07/28/19 09:06 PM

Oh and anything below 60 Hz is handled by my 2 EP800s

Re: ADA1500 - Trigger Cable - 07/28/19 10:31 PM

If your denon had to dish out 650W a side into 4 Ohms from 20Hz on up, it would turn into puddly goo. At 90% efficiency and at that level, the ADA is still turning about 150W into heat. That's like 3/4 of the power of your Denon. LOL.

Re: ADA1500 - Trigger Cable - 07/29/19 12:26 AM

The Bryston 28bcubed mono amp dumps 6100 BTU/hr at 1000W output into 8 Ohms and 2700 BTU/hr at 166W. 6100 BTU/hr is my heat-rated gas fireplace on low.

Looking at it a different way, that Bryston needs 1800W in to produce 1000W out. And 800W in to produce 160W out. Wow!

The ADA is a tree-hugger and the 28bcubed is a depletist.

Re: ADA1500 - Trigger Cable - 07/29/19 11:55 AM

What's even more amazing about that Bryston, is that at 1000W output, the noise is in the picoWatt region. I'd love to know how Bryston pulled that off.

A 1000 Ohm resistor at room temperature and operating with a 10KHz bandwidth generates noise in the nanoWatt region. That's just thermal noise...at room temperature...which the Bryston is not when it's outputting 1000W. This does not include shot noise, burst noise, flicker noise, intermodulation noise or transit time noise. And I'm probably missing a bunch of noises I'm not familiar with. And that's just one element - a resistor. The Bryston has hundreds of elements. And it's 1000 times less noisy than a single resistor!

I guess that's why it costs $US12K for mono!

It has arrived! Now I just have to wait till I get home from my business trip on Thursday. The Fedex guy told my wife it's very heavy wink

Re: ADA1500 - Trigger Cable - 08/01/19 06:18 PM

Well, I hooked it up and 2 of the 3 channels don't work. The one that does work does not sound like it is putting out full power. I tried all cable combinations (RCA and speaker wire). I can get all 3 of my speakers working on channel 3 but none of them on channels 1 or 2. I've sent an E-mail to Ian to see what's next.

Super disappointed... frown

Re: ADA1500 - Trigger Cable - 08/02/19 12:19 PM

I had a problem with my ADA-1000-3 where channels 1 and 2 were in parallel so it was only working as 2-channel. Ian sent me a new one which has been working flawlessly for over 6 months even after I pushed it way past its limits many times. The 1500-3 has also been a total brute and the only thing that brought it to its knees were stacked M5s which is a 2 Ohm load. But even then, I was able to drive those stacked M5s to 107dB peaks at 13 feet away before it shut down...LOL!

Ian is BOSS!

Re: ADA1500 - Trigger Cable - 08/02/19 02:06 PM

I have no doubt it will rock! Ian (who is one of the nicest guys in the world) is having a replacement built; he thinks it was probably damaged in shipping. So, a couple more weeks. Can't wait.

Re: ADA1500 - Trigger Cable - 08/15/19 06:47 PM

With Andrew's help I was able to get the ADA1500 working. I reseated the amp board and it works perfectly now. I contacted Axiom and told them no need to send a replacement. Toughest part was removing the 22 screws that hold the top on! Anyway, hooked it up to the MP5HPs first to test and it is POUNDING on them and it's hardly even warm. Wife and I will be away for a couple of days but I'll be back on Sunday to hook it into the theatre and the M80s and VP100. Loving it so far!

Re: ADA1500 - Trigger Cable - 08/15/19 06:54 PM

The M5s will take everything the 1500 can throw at them. So will the M80s. Your 100 on the other hand will likely ignite and vaporize.

Re: ADA1500 - Trigger Cable - 08/15/19 07:00 PM

Are you getting the "punch" you were looking for?
Posted by: SRoode

Re: ADA1500 - Trigger Cable - 08/15/19 08:13 PM

Certainly with on the M5HPs! I can't wait to hear the M80s and VP180 (typo above, I have a VP180) being really driven! The amp is hardly getting warm, but the M5HPs are 8 ohm loads. I'm looking forward to it pushing three 4 ohm loads!
Posted by: Mojo

Re: ADA1500 - Trigger Cable - 08/15/19 08:30 PM

The M5 is more like a 6 Ohm load. Yeah, they really have a nice sound. BTW, dont dump the entire 1500 into them in 2.0; only in 2.1. Are the M80s v4?
Posted by: SRoode

Re: ADA1500 - Trigger Cable - 08/16/19 03:03 AM

Oh no, I've had the M80s for 12 years, they have the black dot centers on the drivers. I think they are V2.
