CONNECTING AMPLIFIER POWER WIRE TO THE BATTERY

Note: Power cables are as important as battery capacity. Use only high quality power cables of gauge size AWG 8 or larger for installation. YOU CAN NEVER HAVE TOO BIG OF A POWER/GROUND WIRE!

Run the power cable through the interior of the vehicle connecting one end to the amplifiers B+ terminal and connecting the other end to the positive post on the battery. Be sure not to run the power cable together with the audio cables as it would invariably cause radiated engine noise in your audio system. If possible, run audio cables on one side of your car and power cables on the other. Never route these wires underneath the vehicle body.

It is also advisable to install a circuit breaker/fuse 18” from the battery. This would effectively lower the risk of the power cable catching fire should a short circuit occur in the audio system. A circuit breaker or fuse with 50% of the main batteries’ amp hour rating is recommended. Going larger in circuit breaker or fuse value means that you have NO protection. DO NOT over fuse! Fuses on the amplifier DO NOT protect the amplifier, they protect the car.

CONNECTING AMPLIFIER GROUND WIRE TO THE VEHICLE CHASSIS

Find a good ground spot on the vehicles chassis and remove the paint to reveal bare metal at the contact point. Attach the ground wire to that contact point and connect the other end of the ground wire to the GND terminal of the amplifier.

TERMINALS, LUGS AND CONNECTORS

High current terminals, lugs and/or connectors are also required to ensure a safe and sure electri- cal connection and conduction.

CONNECT THE AMPLIFIER REMOTE CONTROL

Connect the remote REM terminal of the amplifier to the remote output terminal of the source unit to establish amplifier remote on/off through the power on/off of the source unit. If the source unit does not provide a remote output, connect to its power antenna lead or other switched 12-volt source, e.g. ignition switch.

RECONNECT THE BATTERY GROUND TO THE VEHICLE CHASSIS

Double check all the previous installation steps, in particular, the wiring and component connec- tion. If everything is in order, complete the installation by reconnecting the battery ground to the vehicle chassis.

CROSSOVER SELECTION

The amplifier has built-in high-pass/low-pass filters that can be defeated by sliding the switch to the OFF position.

1.When the high-pass is selected, the amplifier will be devoted to mid/tweeters.

2.When the low-pass is selected, the amplifier will be used to drive woofers/subwoofers.

3.When the filter is switched off, the amplifier is used as a full range amplifier.

CROSSOVER FREQUENCY SELECTION

Both the high-pass and the low-pass section offer 2 crossover frequencies - 80 Hz and 120 Hz. Choose the setting according to your speaker component specification or to your particular preference.

INPUT SENSITIVITY ADJUSTMENT

The Input Sensitivity Control is located on the Input Panel. The objective of input sensitivity adjust- ment is to match the output of the source unit with the input of the amplifier. The output voltage of individual source units can vary. For example, some source units have an output of 200 mV, others have 5 Volts or more. To cater to these variations, the 161SE amplifier has an adjustable input sensitivity level that ranges from 100 mV to 5 volts.

Adjusting this control requires some experimenting. Basically you want all the gain at the begin- ning of the system, NOT at the end (amplifier). Turn your source unit volume UP and keep your amplifier gains at the minimum possible settings. This will give you the best sound and signal-to-noise ratio.

Besides better sonic reproduction, proper input sensitivity also helps to prolong the reliability span of your amplifier by eliminating excessive internal temperature generated by incompatible source unit output and amplifier input.

Note : Turning the input gain UP does NOT indicate MORE power. Just MORE noise. The input gain control IS NOT a power control. REMEMBER that the input gain control has nothing to do with the power output of the amplifier.
