Listen only to the returns of the 480L. If you have
closely approximated the HF contour and size of the
space, moving MIX should yield a smooth transition
from the rear of the space to the original sound source
(the predominant instrument, vocalist, etc.) If your
approximations were close, doing this will immediately
alert you as to which controls are set incorrectly.
Adding Reverberation
The reverberant contour of the Ambience algrithm is
not a complex as that of the Reverb algorithms. Reverb
Time is linked with the Size control to provide a close
approximation of naturallly occurring reverb time for
the space determined by SIZE. REVERB TIME can be
tailored to taste. Raising the REVERB LEVEL will
increase the level of these later reflections without
altering the balance of the ambient build.
Store your work so far to a register, so that it will
not be lost when you try the following examples.
One reason this program is so powerful is that, when
using conventional analog mixing methods (sends
from dry signal and 480L100% wet MIX on returns or
channels), the console send control emulates a depth
control into the room you have created. If the 480L is
set up in a Stereo Input configuration, the dry signal can
be effectively panned in TWO DIMENSIONS — left to
right, and front to rear.
To try this, set up two sources (such as dialog and
footsteps, or an instrument) on adjacent channels
dual-mono. Each can be panned L-R via the pan
control on the console. The two sends control depth
into the ambience for L or R. (This works wonderfully
with stereo sends!) The independent send level emu-
lates the movement of a single directional microphone
from the sound source into the room with the rear of the
capsule facing a rear corner of the room.
Banks 13-14: the Ambience Programs
Front to rear panning is equal send level X2.
Rear L-R panning is unequal send level.
Front L-R panning is the console pan control
Now, try changing the configuration of the 480L to
Cascade. In MACH A, load the register you stored. In
MACH B, load STEREO ADJUST from the Mastering
program. Using the ROT control on Page 1 of STEREO
ADJUST, you can pan a L+R signal, left to right, against
an L-R signal to shift the image of the ambience. The
SPATIAL EQ control on Page 2 of STEREO ADJUST
can tailor the width of the space. Loading these in
reverse order, you can pan a L+R signal left to right
against and L-R signal to shift the image feeding the
ambience.
Add Predelay as necessary to increase the gap be-
tween the direct sound and early reflections. Note the
Input Delay, as the effect occurs before the dry signal.
Use these two controls to precisely position the source
when using the 480L in the digital domain.
