I just hooked up an inexpensive ($150) receiver (Kenwood VR-505) with digital sound and the bass, treble and bass boost functions are disabled in some digital audio modes. Is this typical for digital sound or should the tone controls work for digital on a decent receiver?

This is typical of Kenwood recievers for sure and probably all others for the most part.


When decoding a digital stream you will be limited to playing around with the Bass management system.


On my old Kenwood VR-307, bass management functions are under "Setup".


It is where you select the Size (NO, NRML, LRG) of your speakers. The bass management has a cascading setup that is not real clear or well documented in the manual. But setting speaker sizes to anything other than LRG has an effect on the next speaker. Atleast with the Kenwood line.


Just play around with the "Setup" to set your speaker Size. And you have to do setup while a movie is playing a 5.1 stream if you want to be able to access the "Surround" speaker "Size" Option.

What about others receivers? Do they typically disable tone controls for digital sound? Is it common or seldom?

In today's typical AV receiver, the tone controls are digitally processed by the DSP chip. During DD and DTS decoding, the DSP chip runs out of processing overhead for extra functions like tone controls. The result, as you've already discovered is that the tone controls won't work during most digital modes.
