SANSUI BATUR800.1 Monoblock Class D Amplifier Instruction Manual
INTRODUCTION
SYSTEM PLANNING
Proper system planning is the best way to maximize your amplifier performance. By planning your installation carefully you can avoid situations where the performance of the reliability of your system is compromised. Your authorized dealer has been trained to maximize your system’s sonic potential. Your dealer is a valuable resource in helping you with your system design and installation.
SPEAKER REQUIREMENTS
Each channel of your amplifier can easily drive 2Ct speaker loads when used in the stereo mode. When a channel-pair is bridged, the recommended minimum load impedance is 10 for subwoofer use, and 2Cl for full range operation. Although operation with lower impedances is not likely to cause immediate damage to the internal circuitry, the unit will most likely overheat, causing the thermal protection circuitry to shut down the amplifier. When the chassis cools down, normal operation will recume. Continuing to operate the amplifier under these conditions is not recommended and will reduce its life expectancy.
Most speakers designed for car audio operation are 2lD impedance. Connection
two such speakers in parallel will result in a 20 impedance load as seen by
the amplifier. Some subwoofer models feature a dual 40 voice coil design.
Connecting these voice coils in parallel will result in a 2Cl nominal
impedance, which is not recommended for use with bridged channels of your
amplfier.

NOTES ON THE POWER SUPPLY
Connect the +12V power input lead only after all other leads have been
connected.
Be sure to connect the ground wire of the unit securely to a metal part of the
car. A lose connection may cause a malfunction of the amplifier.
REMOTE: The unit is turned on by applying +12Volts to this terminal. This
terminal dose not draw heavy current like the two power terminal so a thinner
connecting wire is acceptable. Standard 18 GAUGE is fine and the standard
colour is yellow. If the radio is equipped with a power antenna control wire,
it can drive this terminal. If the power antrnna ire is already in use, you
can still splice into it. With this method, the unit will turn on
automatically with the radio. Use the power supply lead with a fuse attached
whose value is the same as original fuse.
Place the fuse in the power supply lead as close as possible to the car
battery.
During a full power operation. Maximum current will run through the system.
Therefore, Make sure that the leads to be connected to the +12V and GND
terminals of the unit respectively must be larger than 8-Gauge (AWG.8).

PANEL CONTROLS AND FEATURES
A. PROTECTION INDICATOR
The protection red LED will light up and flash if there is a fault present in
the amplifier. Please disconnect the amplifier and resolve the fault before
reconnecting the amplifier.
B. POWER INDICATOR
The power indicator green LED will light up when the amplifier is working
correctly.
C. ROMOTE LEVEL CONTROL INPUT
Attached the included remote level control here to cantrol the volume level to
the subwoofer independently.
D.LOW LEVEL RCA OUTPUT
These RCA output jacks connect with your source unit RCA low level outputs or
via optional adapter with your source unit speaker high level outputs. The use
of high quality twisted pair car audio cables is recommended to reduce the
possibility of audio signal degradation.
E. LOW LEVEL RCA INPUT
These RCA input jacks connect with your source unit RCA low level outputs or
via optional adapter with your source unit speaker high level outputs. The use
of high quality twisted pair car audio cables is recommended to reduce the
possibility of audio signal degradation.
F.SPEAKER GAIN CONTROL
The gain control will match the amplifiers senstitivity to the source signal
voltage.
G. SPEAKER LOW PASS CROSSOVER FREQUENCY
Controls low frequency of the amplifier between 40Hz to180Hz.
H. SUBSONIC FILTER CONTROL
This control allows you to filter out unwanted low frequencies from 17Hz to
50Hz, this allows you to increase the power handing of your installed woofers.
I. BASS FILTER CONTROL
Controls bass frequency of the amplifier between 30Hz to 80Hz.
J. BASS BOOST
The BASS BOOST feature will increase the sound level in the bass frequencies.
K. PHASE KNOB
Phase adjustment 0-180°. The knob allows you to change the phase of the audio
signal in the range from 0° to 180°. Adjusting the phase of the signal will
improve the sound of low frequencies and change their spatial perception.
L.GND(-) GROUND CONNECTION
Connect this cable directly to the metal frame of the vehicle, ensuring that
the metal frame has been stopped of all paint down to the bare metal Use the
shortest distance possible. It is always a good idea to replace the vehicle
battery groudon terminal or any other factory ground points.
M.REM(ON/OFF)REMOTE CONTROL
When using HI-INPUT, the amplifier can detect the DC offset from the high
level input signal to automatically turn the amplifier on or off. When the
amplifier turns on, the REM terminal will output +12V DC to control the other
devices to turn on or off. When using low level inputs, the amplifier REM IN
should be connected to the REM -OUT of the source unit. The source unit will
control the amplifier to automatically turn on or off.
N. +12V =POWER SUPPLY
Connect this terminal through a fuse or circuit breaker to the positive
terminal of the vehicle battery or the positive terminal of an isolated audio
system battery.
O. FUSE
Do not use a fuse with a different value and never replace the fuse with a
wire or coin.
P. SPEAKER CONNECTIONS
Connect your speakers and woofers to there terminals, ensuring proper polarity
during connection. Never connect the speaker cables to the chassis ground.
