XTi2 Series Power Amplifiers
Integrated Processing Features
Operation Manual
The XTi2 Series amplifiers include a number of integrated processing features which appear as icons on the front panel LCD
screen. They are described below:
NOTE: System Architect Software is required to have full control over all Integrated Processing Features which can be
downloaded from the following URL – http://hiqnet.harmanpro.com/. When controlling more than one XTi2 at a time
you will need USB Hub. We recommend using a Powered USB Hub.

output channels. This provides a 6 dB level boost.
signal is ignored.
Output Mode
to the Channel 2 output.
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.
