7. Integrated Processing Features
The XTi 2 . 5 Series amplifiers include a number of integrated processing features which appear as icon 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 mroe
than one XTi2.5 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 (CH 1 +CH 2 ) - 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 amplifier 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 amplifier 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 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 XTi 2 . 5 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 6 dB/oct, Butterworth 12 dB/
oct, Butterworth 18 dB/oct, Butterworth 24 dB/oct, Butterworth 48 dB/oct, Linkwitz-Riley 24 dB/oct, and Linkwitz-Riley 48 dB/
oct. The BandPass gain provides you with - 15 dB to + 15 dB of gain.
