Rod,

A few years ago Yamaha took a plotting mike to several

different venues, fired a blast of sound, and recorded

the resulting echos and reverberations at each facility.

The different Yamaha DSPs simply add the necessary delays

& etc to sound like the material is being played in a

certain 'jazz club', 'consert hall, or whatever.

In general these DSPs are used when playing two channel

sources such as CDs and FM radio to expand the sound a

bit. However, most DSPs add an unatural echo sound to

vocals. Therefore, several 'experts' will tell you, the

new Dolby Pro-Logic II decoders are expected to do a

better job with 2 channel material than the manufacturers

various DSPs.

In my house, with my equipment, FM radio sounds 'very

nice' with the 'jazz club' DSP, and I use '5 channel

stereo' for VCR tapes and CDs.

Yamaha DSPs are loathed by some and loved by others. I can't live without them. OK, maybe that's over-doing it a bit - but I am a big Yamaha DSP fan. These DSP's (Digital Sound/Signal Processing) simulate different environments. You want to listen to a concert CD in concert mode, just press Rock concert, and it simulates a Rock Arena. Simple.

3 factors to enjoying Yamaha DSP's:

(1) The Front Effects speakers. They are important in recreating the different venues.

(2) Many complain about the echo/reverb effects. Too much of it and the whole thing sounds hokey. The higher end Yamaha's allow you to adjust different DSP paramters (including reverb) if you like - to make it more subtle.

(3) An open mind. I didn't like DSP's until I tried Yamaha's versions. My wife lets me shuffle gear all the time - her one constant request ("command") is that the processor be a Yamaha. I agree. We both really like the DSP's.

It's a matter of taste. Enjoy.
