WARNING: It is important to be very careful and follow proper setup when determining if it is possible to use only a Touch (or any other Squeezebox) as a pre-amp to directly drive an amplifier. It is important that before the amp is turned on that the Touch (or other Squeezebox) is verified to be at its minimum digital volume setting and that 100% output option is disabled.
The thing to do is try it. My son and now several of his friends are using a Touch, Adcom GFA-555SE, and a pair of Vandersteen Model 2 Signature II speakers and are enjoying the minimalist setup immensely. Soulkeeper is correct that the Touch might not have enough gain to drive the amp loud enough or it could have to much. So again the only way to find out is by trying it. If it has to much gain then the simple thing to do is add inline attenuators (this is also required to be safe for the speakers if the Touch IS able to over drive the amp). I prefer fixed attenuators by finding out where the limit is as this will always keep ones ears and speakers safe. If it doesn't get loud enough for you, then its time for a pre-amp with a healthy gain stage to drive the amp. Line level RCA outs are normally enough to drive an amp above the safe level of most speakers, but all amps don't have the same amount of gain. As an example, my Class A amp is fine with any Squeezebox or Transporter driving it and the speakers are safe as it never gets louder then I can stand listening even at full output from the Transporter. Where as I HAVE to have attenuators if I drive my Cinepro directly with a Squeezebox. Again be careful when testing. Do things one thing at a time. And double check the setup before applying power to the amps. -- iPhone *iPhone* Media Room: Transporter, VTL TL-6.5 Signature Pre-Amp, Ayre MX-R Mono's, VeraStarr 6.4SE 6-channel Amp, Vandersteen Speakers: Quatro Wood Mains, VCC-5 Reference Center, four VSM-1 Signatures, Video: Runco RS 900 CineWide AutoScope 2.35:1, Vandersteen V2W Subwoofer Living Room: Duet, ADCOM GTP-870HD, Cinepro 3K6SE III Gold, Vandersteen Model 3A Signature, Two 2Wq subs, VCC-2, Two VSM-1 Kitchen: Squeezebox BOOM Bedroom: Squeezebox BOOM Bathroom: Squeezebox Radio Ford Thunderbird: Duet, Mac Mini Ford Expedition: SB Touch, USB drive ------------------------------------------------------------------------ iPhone's Profile: http://forums.slimdevices.com/member.php?userid=13622 View this thread: http://forums.slimdevices.com/showthread.php?t=85096 _______________________________________________ Touch mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/touch
