Amplifier Owner's Manual
BALANCED DIFFERENTIAL INPUTS
A
Provides maximum rejection of unwanted noise from upstream
components.
AUDIOPHILE NJM2068M OP-AMPS
B
Most mobile amplifiers today use the standard NJM4558 op-amp which
has a bandwidth of 3MHz, slew rate of 1V/uSec and noise level of 1.4uV.
The NJM2068M is simply a better performer with a bandwidth of 19MHz,
slew rate of 6V/uSec and noise level of .44uV.
The result is quieter, faster and wider bandwidth performance that
ensures the original music material is reproduced as accurately as
possible.
E
ADAPT POWER MANAGEMENT SYSTEM
Full power output from 11 to 15 volts: ADAPT delivers the same output
power regardless of the vehicle's electrical system voltage. Instantaneous or
long term voltage drops have no effect on the amplifier's power output. This
means more dynamic and less distorted audio output.
Dual power modes provide maximum efficiency: ADAPT seamlessly
optimizes the power supply and Class D operating circuitry by adapting to
the end user's listening habits. When the ADAPT circuit senses lower signal
levels, it will automatically optimize the amplifier's power supply and Class
D circuitry to a low power mode that maximizes efficiency and minimizes
heat to almost zero. As a signal increase is detected the amplifier instantly
shifts into a high power mode, where the power supply and Class D sections
are now optimized to deliver massive power and headroom for those
demanding listening sessions. The amplifier is constantly monitoring and
adapting between these modes which results in higher overall efficiency,
much lower operating temperatures and rock solid reliability.

Key Fea tures
ULTRA HIGH SPEED IR CLASS D CHIPSET
State of the art IR20957 chipset switches at more than 300kHz
for blistering audio performance. All four or five chipsets are
sync'd together in unison to eliminate unwanted harmonics or
distortion.
POST FILTER FEEDBACK
Feedback is when part of the output signal is "fed back" into the
original signal to ensure stability and accurate sound. Class D
amplifiers use output filters (see the 4 vertical coils below), but
most DO NOT INCLUDE these filters in the feedback loop. Ti2
amplifiers INCLUDE or take feedback after its passed through
these filters. The result is more accurate sound that rivals some
of the best class A/B amplifiers.
F
THERMAL ROLLBACK CIRCUIT
Under most conditions, Ti2 amplifiers generate moderate
to low heat. However, if extreme conditions exist, as
temperatures rise the amplifier will automatically adjust the
power output, so your music continues to play. These changes
are inaudible and vastly reduce the chance for any thermal
shutdown events.
LOW EMI CIRCUIT BOARD DESIGN
Most class D amplifiers can emit EMI noise that can cause
problems with AM/FM reception or other devices in the
vehicle. Ti2 amplifiers have undergone intense real world
engineering and testing to vastly reduce or eliminate these
issues. Careful PCB layout using four layers (most amplifiers
feature just two) along with many key filters ensures a very
low possibility of any interference issues.
