BATUR60.4 Sansui Batur Series Amplifiers 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 20 speaker loads when used in the stereo mode. When a channel-pair is bridged, the recommended minimum load impedance is 40 for subwoofer use, and 20 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 20 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 20 nominal impedance, which is not recommended for use with bridged channels of your amplfier.

POWER CONNECTION LEADS
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 wire 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. There-fore, 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. CH3/CH4 SPEAKER HIGH PASS CROSSOVER FREQUENCY Controls high frequency of the amplifier between 120Hz to 3KHz.
- B. CH3/CH4 SPEAKER CROSSOVER CONTROL
Depending on the selected switch the amplifier will operate at full or hpf or 1pf mode. - C. CH3/CH4 SPEAKER LOW PASS CROSSOVER FREQUENCY Controls low frequency of the amplifier between 50Hz to 250Hz.
- D. BASS BOOST
The BASS BOOST feature will increase the sound level in the bass frequencies. - E. SPEAKER GAIN CONTROL
The gain control will match the amplifiers sensitivity to the source signal voltage. - F. LOW LEVEL RCA INPUT
These RCA inputjacks 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. - G. 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. - H. PROTECTION/POWER 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. The power indicator green LED will light up when the amplifier is working correcly. - I. CH1 /CH2 SPEAKER CROSSOVER CONTROL
Depending on the selected switch the amplifier will operate at full or hpf mode. - J. 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.lt is always a good idea to replace the vehicle battery groudon terminal or any other factory ground points. - K. 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 tum 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. - L. +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. - M. FUSE
Do not use a fuse with a different value and never replace the fuse with a wire or coin. - N. SPEAKER CONNECTIONS
Connect your speakers and woofers to there terminals, ensuring proper polarity during connection. Never connect the speaker cables to the chassis ground.
