my first use is to power a dodecahedron loudspeaker-three speakers to each amplifier. that way i will get more power out of 12 volts. i just finished 3dprinting the loudspeaker.
i will build a portable 8 channel system with 3-inch speakers that i would like to take around for ambisonic demonstrations in colleges etc. i should check the specs for the ic.it is a single chip and the board looks well made - it says 50 watts per channel, but i would be happy with about 18watts into 4 ohms per channel. (it should be capable of that much - these are bridge outputs. umashankar > Date: Sat, 31 Oct 2015 10:42:43 +0000 > From: augustineleu...@gmail.com > To: sursound@music.vt.edu > Subject: Re: [Sursound] 8 channels on 12 volts > > Ooooh for me this is very interesting.
