whether DELAY BYPASS is in or out. So to match levels, first set the OUTPUT
MIX MASTER control to give the desired output level (from the MASTER OUTPUT)
while the DELAY BYPASS is in. Then switch the DELAY BYPASS out and adjust
the levels of the four OUTPUT MIX functions for the same overall output

See FIG. 3.4
With M.93 delay times are not restricted to the range of the DELAY SELECT
controls. Turn the DELAY MULTIPLY switch to increase the indicated delay
by a factor of 2,4, or even 8 with a corresponding decrease in the frequency
bandwidth. The bandwidth is limited by steep 30 dB/octave filters to avoid
high frequency digitizing errors known as aliasing. Using DELAY MULTIPLY,
the short 128 msec echo from section 3.1 can be lengthened to a healthy
512 msec or even 1.024 seconds at multiplication factors of 4 and 8 respec-
tively. With the optional extended memory, a maximum delay of 2.048 seconds
can be achieved.
SOFT REFLECTIONS
r-
In the real world sound reflected from walls and other surfaces loses some
of its high frequency content. If the surface is soft or padded such as a
curtain or rug, more high frequency content will be lost than if the surface
