XTi2 Series Power Amplifiers

Integrated Processing Features

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 – ht tp://hiqnet.harmanpro.com/.
When controlling more than one X Ti2 at a time you will need USB Hub. We recommend using a
Powered USB Hub.

Input Mode

• Stereo - In this mode, Channel 1 input goes to Channel 1 output and Channel 2 input goes to Channel 2

output. This is the mode the amplifier is configured for from the factory.

• SUM (CH1 + CH2) – In this mode, the Channel 1 input signal and Channel 2 input signal are summed and

fed to both output channels. This provides a 6 dB level boost.

• Input Y – In this mode, the Channel 1 input signal is sent to the Channel 1 and Channel 2 output. The channel

2 input signal is ignored.

Output Mode

• Stereo – In this mode, the amplier sends Channel 1 input signal to the Channel 1 output and the Channel 2

input signal to the Channel 2 output.

• Bridge-Mono – In this mode, the power of both amplier channels are delivered into a single 8 or 4 ohm load.

Subharmonic Synth

The Subharmonic Synth feature takes the low frequencies and “synthesizes” or creates new frequencies that are
one octave lower. The t wo 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 equaliz ation 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.

Operation Manual

XTi2 Series Power Amplifiers

Integrated Processing Features

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.

PeakX Plus Limiter:

Feed-forward output limiter with user-adjustable attack, release and threshold (0.1 dB resolution), plus
integrated feedback limiter to minimize amplifier clipping.

Advanced Thermal Control

In this section, you can tailor the fan speed to specific applications. You have the choice of the following modes:

• Normal

• Early

• Full-Speed

The fan mode can be changed using the front panel buttons at start-up or in the sof tware. 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 Nex t at the same time until the screen says
“locked”. The rotary knobs (attenuators) will still operate. To unlock, hold Prev and Nex t until the screen says
“u nlo cke d”.

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.
