The SSD-66 (THX) Surround Sound Decoder
The Delta System permits any one, two, or all three zones, to become home theaters when using
ADA's SSD-66 Surround Sound Decoder. For such rooms, the MC-3000 keypad not only
communicates and controls the Delta-3 for source selection, but also the SSD-66 for volume
control, mode selection, setting of rear channel delay times, recall of the volume preset, and
engage the AGL Enhancement circuit on, off, or auto (not available in all modes.) Keypads for
ADA home theaters will not have bass and treble buttons.
Adjusting Volume
The SSD-66 is unique in that it displays volume levels, not as an overall volume indication, but
rather in numeric levels for each channel, front right, front left, center, and surround. These
numeric levels are calibrated in decibels (dBs) and appear both on the SSD-66 and the keypad.
To raise or lower volume levels, simply press and hold the VOL UP or VOL DN buttons. The
display will indicate the volume levels going up, -67 (full mute) to
-23 -23 -24 -22

Your installer will program in a volume preset which is designed to
provide the optimum volume levels for your home theater. To
regain these volume parameters, simply press the VOL PRESET
button. The display will read VOL PRESET and then the numeric
volume levels will appear on the keypad. You can then raise or lower
the volume by pressing the VOL UP and VOL DN buttons.
Changing Modes
The SSD-66 has several modes ideal for film, TV, and music. To scroll
through the various modes, press the mode
button. Every time you press the mode
button, the SSD-66 will advance to the new
mode. The name of the mode will appear
on the keypads display exactly as it ap-
pears on the SSD-66's.
Consult your SSD-66 (THX) Owners
Manual as to the modes available on your
SSD-66 and how they augment your view-
ing or listening experience.

+12 (extremely loud). While volume lev-
els may differ between channels, the SSD-
66 will track the volume levels maintain-
ing the separate levels. The volume level
will not exceed the first channel to reach
+12. The volume will drop as low as -67 for
all channels.
