Teac AG-V3050 - SURROUND SOUND ADJUSTMENTS; Delay Time and Volume Balancing

[Delay Time _ =]
In the surround modes, the sound from the rear
speakers should be delayed slightly, relative to that
from the front speakers. The optimum delay time will
be different in rooms of different sizes and will depend
on acoustic properties, whether the walls and
furnishings reflect or absorb sound, etc. It is
recommended that you try different delay times to
obtain the best effect. The delay is digitally
synthesized, for the highest sound quality with
minimum noise and distortion.
The delay time can be set independently for each
surround mode using the DELAY TIME button (@), with
the current setting shown in the display.
