Technical Pro Rack
Technical Pro Rack
Hope I dont sound too crazy or stupid, needing some input on unusual home stereo system please.?
I have a Bose Lifestyle 50 system. The cool thing about these systems is that you can branch off of your main system and send the signal to other receivers or amps to run different rooms. I got the adapter cords to go from the Bose setup to any other brand of receiver as long as they take RCA jacks. I decided for one of these "rooms", I wanted to branch off to the outdoors since I spend quite a bit of time outside and would like to be able to hear it well at any spot on the farm. I got 4 pairs of Bose 251 outdoor speakers. I have a Technical Pro LZ-3000 Power Amplifier that's made to slide into a rack(not exactly a home Stereo Amp, but I think it could be).If it's ran using 2 channel output, it's rated at 8 ohms: 2x150W, or 4 ohms:2x225W. If it's bridged, it says 8 ohms:450W. Should I use a preamp? How could I wire all 8 speakers so that I would be getting the power distributed evenly and not damage anything? If you need to know any other details let me know, and I'll add more details
Despite what Thinkenstein said, you will need a preamp for that amp, even though it has front gain (volume) controls, that amplifier does not have a built in preamplifier.
It is not a home Audio Amplifier, it is a very low end PA amplifier. Technical Pro amps are even worse than Pyramid amps. If I was you I would return it or try selling it on eBay.
The problem with Technical Pro amps is they rate them by their peak power not their true power output. The sad thing is the power rating they state on their site as being the true power is even false, The fans on these amps are also very loud, they can't handle 4 ohms long term & have thermal issues.
The Technical Pro SL1200 makes a buzz without any input at all.
Technical Pro amps are consumer grade amps that are disguised to look the part of & passed off as pro grade amps. I guess you can say they are made on the outside to look Technically Pro on the outside but merely consumer grade on the inside sort of like having a sports car with all looks but no go.
Now I know a new QSC, Crown, or Lab Gruppen amplifier may be more than you want to spend, so I suggest you keep an eye out on eBay & Craig's List for a used QSC amplifier, a used Crown amplifier, or a used Lab Gruppen amplifier. It's better to have a used Toyota than a new Kia.
I recommend looking for a used QSC RMX 850 or QSC RMX 1450.
edit:
Read Thinkenstein's update.
"Your Bose system effectively functions as a preamp." "You wont hear the fan if you are in one of the other zones." "since you already have this one it won't hurt to try it."
