NAVIgATINg THE LCD SCREEN MENU:
BASICS
To step through the Menu options, press the Sel,
Next or Prev buttons as described in the table
later in this manual.
ICONS illuminated at the top of the screen show
which DSP functions are active with the current
preset.
When you are modifying a preset, its ICON flashes.
You can scroll through its settings with the Prev
and Next buttons. When you see the desired
setting, select it by pressing Sel.
Doing nothing returns you to the CURRENT
PRESET after ten seconds.
In the LCD screen, if the PRESET icon is lit, the
current pre set is unchanged from its stored
settings. If the CUSTOM icon is lit, the current
preset has been changed from its stored settings.
USER PRESETS: The CDi amplifier provides 19
user presets which you can modify. For example,
set up a user preset with a specific crossover
frequency and a specific limiting threshold.
DSP PROCESSES
The CDi amplifier includes a number of DSP
processes, which appear as ICONS on the screen.
They are described below:
Output Mode: The options are:
• 70V (70V/high-Z mode for Ch. 1 or Ch. 2)
• High Z – Channel is configured for 70V/high-Z
loads.
(A 70Hz high-pass filter is automatically enabled
whenever 70V is on.) It is a 24 dB/octave
Linkwitz-Riley filter in the crossover section.
• Low Z – Channel is configured for low-Z loads.
Input Mode: The options are
• CH1+CH2 (Ch.1 input signal and Ch. 2 input
signal are summed and fed to both output
channels.) This provides a 6 dB level boost.
• INPUT Y (Ch. 1 input signal goes to Ch. 1 and
Ch. 2 output. Ch. 2 input signal is ignored.)
• STEREO (Ch. 1 input goes to Ch. 1 output. Ch. 2
input goes to Ch. 2 output.)
XOV (Crossover): The available crossover
frequencies are: OFF, 90 Hz, 100 Hz, 1200 Hz, 1500
Hz, 2000 Hz, 2-CH SUB, CUSTOM.
When you call up the XOV process, Ch.1
will always be set to low frequencies and
Ch. 2 will always be set to high
frequencies. DO NOT con nect high-
frequency drivers to Ch. 1.
EQ (Equalization for Ch. 1 or Ch. 2): The
options are OUT or IN. When set to “IN”,
equalization that you set up in System Architect
software is applied to the signal. When set to
“OUT”, equalization is bypassed.
DEL (Delay for Ch. 1 or Ch. 2): The delay times
are OFF, 1-10 msec, 10-50 msec, and 0 sec. “0
sec” is a placeholder for any delay time set in
System Architect soft ware.
BRg (Bridge-mono or Stereo): Use this
option to set the amplifier to bridge-mono or
stereo mode. When BRIDGE is active, the Ch. 1
input signal is used (unless you made an
alternate setting with the Y processing block).
The tables on the next few pages describe what
button sequence to press in order to achieve
various functions. Four identical tables are
provided, each in a different lan guage, for easy
use in the field.

* When you call up the XOV process, Ch.1 will always be set to low frequencies and Ch. 2
will always be set to high frequencies. DO NOT connect high-frequency drivers to Ch. 1.
