Amplifier Owner’s Manual

A

BALANCED DIFFERENTIAL INPUTS

Provides maximum rejection of unwanted noise from upstream

 

components.

B

AUDIOPHILE NJM2068M OP-AMPS

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.

 

KEY FEATURES

C

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.

D

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. SD

 

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.

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.

F

THERMAL ROLLBACK CIRCUIT

Under most conditions, SD 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.

G

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. SD 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.
