![]() ![]() The five pink noise tracks are for each of the five speakers. I put my sound pressure level meter on a tripod at the listening position and at ear level. The great thing is that you need not be “technically minded” (I’m certainly not) to use it effectively. The Philip's SACD Surround Sound Reference Disc is very straightforward to use. (Pink noise contains equal energy per octave, so it is readily distinguishable from “white noise”, that contains unequal or random energy across the audio spectrum). ![]() I’m sure these tracks (and many others on the disc) can be helpful in fine tuning a multi-channel environment, but the raison d’etre for this disc are the 5 tracks with pink noise, that are needed for multi-channel calibration. Most of these tracks are of only passing interest to me, such as “Harrier Jump Jet”, “ A Big V8”, “Motorbikes”, “The Sailors Hornpipe” from Oldfields’s “Tubular Bells”, etc. The Philip's SACD Surround Sound Reference Disc has tracks specifically for multi-channel SACD (*not* home theater) setup. But reading remarks of numerous audiophiles and music lovers (most who interchangeably swap/confuse “home theater” and “ SACD multi-channel music) who have invested in multi-channel systems vary rarely is a set up disc mentioned. You have to be exceedingly lucky to get things balanced without a reference disc. Otherwise I believe set up of a SACD multi-channel system is a crap shoot with only a smidgen of a chance of getting your system set up correctly. The Philip's SACD Surround Sound Reference Disc is a *must have* tool, in my opinion, along with a sound pressure level meter, for setting up a SACD multi-channel system. ![]()
