I'm in the market for a new receiver to use as a preamp with my existing amplifier. I'm considering the pioneer 1120, which does not have a 12V trigger. I've read all about the workarounds for this, including using a smart power strip.


However, in thinking through the issue I realized that my Sony HS51 front projector does have a 12V trigger (presumably for use with an electric screen), and that it would be fairly simple to run a mono/stereo cable from the projector to the equipment closet, as I ran conduit when I did the original install.


Is there any reason this wouldn't work? I only use my theater room for movies and TV, so there are very few situations in which I would want the amp/preamp combo turned on without the proector running.


Has anyone else tried this?

Why not get a dedicated pre/pro and most likely have triggers?

@james...


assuming that the amp is happy with the output from the pj, there's no reason why it shouldn't work... the amp doesn't know it's coming from a pj/avr/wherever...


@vitod... if you can name any fully functional pre-pros that you can purchase for anywhere near the price of the 1120, i'm all ears....

Yeah, as ccotenj alluded to, I'm looking to upgrade to the latest feature set, but not interested in spending a ton of money to do so. Would like to keep it under $500 or so.


Was a little surprised that in searching the Pioneer 1120 threads I didn't see any reference to using a projector's 12V trigger, as I would guess that quite a few people interested in using the 1120 as a preamp have a front projector setup.

that's likely a correct guess... anecdotal evidence would suggest that at least 95% of the 1120 buyers are watching little tv's (i.e. under 50 inches)... with any number of them mounted above a fireplace, no less...

to be honest, i never even knew a pj had a trigger, so i'm glad i stumbled on this thread...

What external amp ?

What projector ? Are you sure that the projector is not a 12v trigger to turn on the projector...?


Unless its a huge outputting amp, the smart strip will handle all your needs.... I my Preamp as a startup for a few devices on the smartstrip, just not my amp, which is a dual chord Wyred4Sound.


It works without me thinking about it, set it up 1 time and done. I have absolutely no complaints...

The amp is the Sherbourne 1500a. The projector is the Sony VPL HS51. I'm fairly certain the 12V on the projector is to turn on an external device, rather than the projector, but you raise a good point, and I should check my manual before proceeding.


Which smart strip are you using?

 

[Warpdrv]

One just like this.... http://www.buy.com/prod/bits-scg3-7-...206574207.html


I use the 12v off my Pre-Pro to turn on my speaker amp, but I have a few medium power items powering up off the smart strip.


Hmmm I'm not sure If I would want to power that amp off the smart strip.... 200w x 5


What I would do in this case, is use the smart strip to turn on a 12v wall wart and put a mono end on it to therefore turn on the sherborn..... very simple to do and will be relatively inexpensive. You would have enough power to engage a couple of 12v triggered devices....


This is what I do to turn on the external pro amps I have for my DIY Subs....

The projector's trigger should be an output, as it's usually intended to open a powered screen or retract curtains covering a screen. There's no reason you couldn't use it to trigger a power amp instead, but then you're going to have to turn the PJ on every time the system is powered up. That could become problematic if you also use the system for only listening to music sometimes.

If you are wanting the 12v trigger, go with the Pioneer Elite 32. You should be able to find one for not much more than the price of the 1120 plus some of power strip options. Retail, it is $50 more.


The other option is to use your favorite finger and push the power button. Anytime I'm starting a movie I am standing in front of all of the electronics. And when I'm done with a movie, I am back within arms length of all of the buttons. In your case, the elite 32 or 33 maybe your solution, but for me and my setup, I like giving my system the finger.

After watching the 1120 thread grow from its first post, I think you are on to something with the 5% guess. I bet there is a strong correlation to the tv being mounted above the fireplace and the inability to lift open the cover on the manual.

There are maybe simpler options? If the receiver has AC outlets, a simple 12V DC wall wart will do.


Or some people have done it with a power strip and a wall wart.

I doesn't have a AC outlet

Both RoboRay and heyall have very good suggestions here...

I think the least expensive route would be to trigger off the projector, but for $50, I can't see why anyone would not just get the elite...
