Thank you for purchasing the Lanzar OPTI Class-D amplifier. Rest assured you have purchased a quality product designed and engineered to give you many years of uncompromised musical service. The OPTI Class-D amplifier has been designed using the latest in electronic technology available today. This mono subwoofer amplifier is the result of advanced high speed switching technology that overcomes the less-efficient classAB design.
CLASS-D DESIGN Low - frequency information for subwoofer only. High efficient power POWER SUPPLIES Stiffly regulated PWM power supplies. MOSFET switches maintain rated power over a wide range of battery voltages. LOW PASS FILTER Adjustable from 50Hz to 150Hz with a slope of 24dB per octave. This allows for the adjustment of the upper point of the frequency bandwidth and the respective subwoofer. VARIABLE SUBSONIC FILTER Adjustable from 15Hz to 40Hz with a slope of 24dB per octave.

1. Find a suitable location in the vehicle to mount the amplifier. 2. Make sure there is sufficient air flow around the intended mounting location. 3. Bolt the amplifier to the mounting surface. 4. Connect the power ground terminal to the nearest point on the chassis of the car. Keep this ground wire less than one meter (39") in length. Use 4 gauge wire. 5. Connect the remote terminal to the remote output of the head unit using 14 gauge. 6.

1. Line Out RCA Jacks - The LINE OUT allows you to build multiple amplifier systems with out having to use splitter cords to distribute the signal. Now it is simple a matter of bringing one set of RCAs into the first amplifier, then using the line out RCA jacks as the feed to the next amplifier. 2. Input RCA Jacks - These inputs are for signal cables from the source. Always use high quality shielded RCA cables. 3.

Before removing your amplifier, refer to the list below and follow the suggested procedures. Always test the speakers and their wires first. Check for good ground connection. Check that remote DC terminal has at least 13.8v DC. Check that there is battery power on the +terminal. Check all fuses. Check that Protection LED is not lit. If it is lit, shut off amplifier briefly and then repower it.
Check for shorts on speaker leads. Check that the volume control on the head unit is turned down low. Remove speaker leads, and reset the amplifier. If the Protection LED still comes on, then the amplifier is faulty. Check that the minimum speaker impedance for that model is correct. Check for speaker shorts. Check that there is good airflow around the amplifier. In some applications, an external cooling fan may be required.
