Subharmonic Synth
The Subharmonic Synth feature takes the low frequencies and “synthesizes” or creates new frequencies that are one octave
lower. The two signals are then summed together. Also new, are two user adjustable parametric EQ filters and crossover
frequency filter. These can be used to “shape” the sound and enhance the desired effect.
Equalization
The XTi2 Series provides two blocks of equalization in the signal processing. The input EQ block is before the crossover and
is usually used for the room EQ. The output EQ block is after the crossover and is usually used for speaking tuning.
Input EQ: This input EQ block provides 6 filters per channel each with frequency, gain, and Q that is user controllable.
This block also has a High and Low Shelf Filter per channel which has gain and frequency control.
Output EQ: This output EQ block provides 8 filters per channel each with frequency, gain, and Q control that is user
controllable.
Crossover:
The crossover section provides users with the ability to enable a HighPass and LowPass filter per channel along with
BandPass gain and the ability to change the polarity. This allows the Crossover section to be customized to most system
configurations.
For the HighPass and LowPass Filters, you have the choice of the following filters: Butterworth 6dB/oct, Butterworth 12dB/oct,
Butterworth 18dB/oct, Butterworth 24dB/oct, Butterworth 48dB/oct, Linkwitz-Riley 24dB/oct, and Linkwitz-Riley 48dB/oct.
The BandPass gain provides you with -15dB to +15dB of gain.
Delay
There is up to 50msec of delay available in the signal processing for time aligning your speakers. The software allows you to
enter the amount of delay needed in the form of seconds, feet, or meters and does the calculation for you.
Peak Plus Limiter:
X
Feed-forward output limiter with user-adjustable attack, release and threshold (0.1 dB resolution), plus integrated feedback
limiter to minimize amplifier clipping.

Integrated Processing Features
Advanced Thermal Control
In this section, you can tailor the fan speed to specific applications. You have the choice of the following modes:
tꢀ /PSNBM
tꢀ &BSMZ
tꢀ 'VMMꢅ4QFFE
The fan mode can be changed using the front panel buttons at start-up or in the software. The default mode is normal and
should work fine for most applications. Early mode turns the fan on sooner at a “lower” temperature, and Full-speed mode
turns the fan on full-speed full-time. Full-speed mode is not recommended for “dirty” environments.
Advanced Monitoring
This feature allows you to have software visibility of both the Power Supply Temperature and AC Line voltage. AC Line
voltage is “derived” from the amplifier rail voltage and is an approximation of the AC line voltage. This allows you to monitor
the health of your amplifiers and provides for troubleshooting.
Front Panel Lock-Out
To disable or lock the buttons from the front panel, hold the Prev and Next at the same time until the screen says “locked”.
The rotary knobs (attenuators) will still operate. To unlock, hold Prev and Next until the screen says “unlocked”.
The front panel can also be locked out from the software as well from the main panel. However once it is locked in
the software, it can only be unlocked from the software. You cannot unlock from the front panel. The rotary knobs
(attenuators) will still operate.
