Re: Need low-budget power amp for AL-III Plus's

Thanks Angelo, leaving well enough alone for now, but have taken some notes for future reference. It's taken me a while due to other commitments, but I've tried out the amp with different wiring configurations, figured out the pre-amp zone control, and sweated a little while learning the equipment (...

... and the verdict is ...

Bi-wire!!! Both Steve and I felt it was easier on the ear, and I got the fullness of base that was missing with current-only wiring. Ordered 4 strand wire last night (for under house) and will use some of the 2 strand I previously ordered to make patch cables (wall jacks to speakers) following this...

Re: Wiring a Sunfire 300x2

Not wanting to originally move them got me into linear thinking that more wire was the only solution. Just need to move them closer to the amp. #-o Never used to have mental paths like this, but middle-age is showing I guess.

Re: Wiring a Sunfire 300x2

OK, I've tried out using only current. Pretty, but not much base. Using only voltage, the base seems to override the ribbons, muddying the sound. So... I do now want to try bi-wiring current to ribbon, and voltage to woofer. I have enough wire to wire one speaker this way, and leave the other using ...

Schematic for Sunfire 300x2?

Does anyone know where I can get a schematic for this amplifier?

Woofer issue was just loose bus plates <g>.

Re: what to expect with a 2.0v rms difference

I'd plugged in numbers to those formulas and came up with the numbers. New formula (10:1) is easier. My Yamaha Rx-A1010 has output impedance of 1.2k, and the Sunfire input impedance 24k, so it looks like I'm twice what I need and "am golden" ;-)

Re: what to expect with a 2.0v rms difference

Thanks Gary.

Re the manual: Not sure how input sensitivity alone would answer my question as to what to expect :-k . I did reference the manual (sensitivity etc), to input into the formulas in the article.

what to expect with a 2.0v rms difference

I stumbled on this article (http://www.audioholics.com/audio-amplifier/amplifier-voltage-gain) when looking for advice on setting the impedance on my pre-amp. I found the answer to that out elsewhere, but got curious about how my pre-amp and amp matched up. I followed the formulas and came up with t...

Re: Need low-budget power amp for AL-III Plus's

Due to a lot going on around here, we just got the Sunfire 300x2 hooked up for a trial run. Loved hearing each guitar string struck on 10000 Maniac's MTV Unplugged. My music-indifferent husband had a big-ass grin, and my toddler was dancing around being all happy and such! No sound from one of the A...

Re: Wiring a Sunfire 300x2

Thanks for the clarification. It must have been somewhere else I was reading that spoke of efficiency. The wiring is just stubs to the underside of the house, so I still need to buy 100' of wire even if using 2 stand. Regardless, I'm going to go ahead and complete the wiring and jacks for 2 strand, ...
