Setting Channel Levels
The leftmost display on the front of the D1650
shows which channel is selected for adjustment.
Pressing C+ or C- will cycle through each individual
channel. Once a channel is selected, use the V+ and
V- buttons to adjust the channel’s Volume Up or
Down from 0 to 100 (50 is Factory Default).
Each amp channel can be individually adjusted from
the front panel. Pressing the C button will cycle
through all the inputs on the amplifier — both Left
and Right channels can be adjusted independently.
The C button to the left cycles downward, the one
on the right cycles upward. When the desired chan-
nel is displayed on the front panel, use the V but-
tons. Again, the V button to the left lowers the vol-
ume for that channel, the one on the right raises
the volume.
Set the levels by lowering them all the way down,
then raise the volume of any keypads or volume
controls to maximum. Slowly adjust Volume Up for
this channel until the red clipping LEDS start to light
up, then drop the level one or two clicks. Follow
this procedure for all channels.
Please Note: Whenever the Front Display is lit (dur-
ing volume adjustment, for example), ACE clipping
elimination circuitry is disabled.
Lockout Mode
The Lockout feature is designed to disable all front
panel functions. Use this feature once the system is
fine-tuned and ready-to-go. By locking the sys-
tem’s front panel, prying hands cannot ruin carefully
set level adjustments or overdrive speakers.
To place the D1650 in Lockout Mode:
1. With the Front Display dark, Press C- and V-
simultaneously.
2. Continue pressing C- and V-. The Front Display
will show the Volume setting momentarily.
3. Four seconds later, the Front Display will read
LOCK. Release the buttons.
4. Follow the same procedure to Unlock the D1650.
Please Note: If the user tries to change settings
while in Lockout Mode, the Front Display will read
“VOLUME LOCK IS ON”.
