POWER OUTPUT NOTE: A power birth certificate is included for each amplifier. SD amplifiers are conservatively rated and will exceed their RMS power rating shown here. All RMS power ratings and measurements are at 14.4 volts with no more than 1% THD. SD800.4 and SD1100.5 feature ADAPT technology which provides the same power output from 11 to 15 volts with music material.

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. |

SD800.4
4 CHANNEL POWER AMPLIFIER
FRONT AND REAR INPUTS
Connect preamp signal cables from headunit to these inputs. The front AND rear inputs must be used, if only the front input is used then the rear speaker outputs will have no output signal.
CROSSOVER FREQUENCY
Controls the crossover point for the speaker outputs.
BASS BOOST
Variable bass boost from 0 to +18dB @ 45Hz.
SENS
Used to reach maximum amplifier power with a wide variety of headunits.
CONFIG
FLAT: Crossovers are turned off
HP: High pass crossover is on
LP: Low pass crossover is on
+12V
This must be connected to the fused positive terminal (+12V) of the car’s battery. The fuse must be located within 18 inches of the battery.
REMOTE
This must be connected to switched +12V, usually a trigger wire coming from the head unit or ignition.
GROUND
This must be connected to the negative terminal of the car’s battery or bolted to a clean, unpainted part of the chassis of the vehicle.
REMOTE MONITORING DISPLAY (RMD)
Connect optional RMD Voltage Display to this port.
SPEAKER OUTPUTS
Used to connect the amplifier to speakers. SD800.4’s minimum impedance is 4 ohms bridged or 2 ohms stereo. Use the Left + and Right - to bridge the channels.
