I-Tech
HD DriveCore Series offers
amazing power, light weight and ease of use for
touring sound applications. Unlike other
amplifiers, it includes onboard high-definition
DSP, a 4.3” LCD TFT Capacitive Touchscreen,
and a built-in network connection.
Modern power amplifiers are sophisticated
pieces of engineering capable of producing
extremely high power levels. They must be
treated with respect and correctly installed if
they are to provide the many years of reliable
service for which they were designed.
In addition, I-Tech Series amplifiers include a
number of features which require some
expla nation before they can be used to their
maxi mum advantage.
Please take the time to study this manual so that
you can obtain the best possible service from
your amplifier.

®
with
Drivecore Technology) cir cuitry couples power
efficiently to the load and provides low AC
current draw.
• Onboard high-denition analog devices
Sharc
®
processor DSP with 24-bit, 192 kHz
SHARC A/D and D/A converters. Advanced IIR
