Digital Class-D Linkable Mono Block Amplifier

Before operating this unit, please read this manual and keep it for future reference

Congratulations, and thank you for your purchase of Incriminator Audio amplifiers.

Like all of IA's products, the 20.1 series amplifier was designed with only one thing in mind.....Performance!

The new 20.1 has been completely redesigned, and comes with many performance upgrades.

The first and major upgrade you will notice when you opened the box should be the new case design.

You may be surprised to see that the new amplifier has grown SMALLER in size.

Don t be alarmed, smaller doesn t always mean less performance.

In fact, IA believes smaller can mean bigger! New technology has allowed us to use fewer and smaller

parts on the board and in effect, has allowed the amps to become more efficient using our multi-layering

technology to protect themselves better than ever, bullet proof technology is here to stay.

Once again congratulations, and THANK YOU for being a valued Incriminator Audio customer!

* The SLAVE amplifier should be in

"SLAVE" position in a parallel operation mode.

* The MASTER amplifier should be in

"MASTER" position in a parallel operation mode.

to SLAVE UNIT "SLAVE INPUT"

If no sound, please check the MASTER/SLAVE switch.

The mode switch should be in MASTER position,

if in SLAVE position the unit will not play

+12V Power

Connect the +12V (B+) terminal of the amplifier to the + terminal of the battery using the same size

cable for both the power and ground, we recommend 1/0 gauge wire. Make sure you install a fuse or

breaker approximately 12 to 18 inches from the + terminal of the battery. Make sure there is no

fuse in-line or the breaker is turned off until installation is complete.

GROUND

Disconnect the battery and connect the (GND) ground terminal to the car frame. Keep this cable

as short as possible, not longer than 30 inches. Make sure the connection with the frame is secure

and the connection is free of ruse and paint.

REMOTE

Connect the REM terminal of the amplifier to the power antenna terminal in the car

ignition switch using 12 or 16 ga. electrical wire.

Caution

This amplifier is not supplied with an internal

fuse. Make sure you install an in-line fuse from

the + Terminal of the battery.

We recommend a 200 amp fuse.

GROUND

BATTERY

Please note that this unit is a mono block unit and only has one channel Speaker A and Speaker B are

just labeled for clear illustration.

Hooking to either the positive or negative of either of the two connections will end in the same result

as both positive connection and negative connection are tied together inside the unit. If for example

you connect 2 subwoofers that are 2 ohms each the amp will parallel the 2 connection for a 1 ohm load.

1~4 ohms

2~8 ohms

SINGLE AMP SPEAKER CONNECTION

-5-

When using two amplifiers and strapping them together, the MASTER amplifier has total control over

the SLAVE amplifier. When using two amplifiers to power a subwoofer, the positive terminal of

the subwoofer s voice coil must be connected to the positive terminal of the MASTER amplifier.

The negative terminal of the subwoofer s voice coil must be connected to the positive terminal of

the SLAVE amplifier. You must then connect the two amplifiers together with an 8 gauge wire by

hooking both negatives of each amplifier together, this along with the chaining the RCA s together

on the bottom section of page 3 complete strapping. Incriminator Audio amplifiers strapped together

create massive amount of power, please check the rating on your subwoofers to make sure there power

handling is not exceeded.

In strapped mode your total impedance must be at least 2 ohms, any impedance less than

2 ohms could possibly damage your amplifiers

This power amplifier has protection features to prevent any damages from misuse or faulty conditions.

If the unit senses excessive heat, short circuited speakers or overload, the protection indicators

will light, and the system will be turned off. In order to check the occurred problem, you should turn

all levels down and all power off and carefully check the installation for wiring mistakes or short.

If the amplifier shuts down due to excessive heat, the protection indicators will not light : simply allow

time for the unit to cool.

Before removing your amplifier, refer to the list below and follow the suggested procedures.

Always test the speakers and their wires first.

PROTECTION LED ILLUMINATES WHEN AMPLIFIER IS POWERED UP

FUSE BLOWING

OVERHEATING

Check that the minimum speaker impedance is correct.

Check speaker shorts.

Check that there is a good airflow around the amplifier.

Check a good ground and for speaker shorts.

Disconnect all RCA inputs from the amplifier. If hiss/noise disappears, check it with a good RCA

interconnect. Then check the component driving the amplifier.

SOUND TOO LOW-DISTORTED SOUND

Check that the input level control is set to match the output level of the unit.

Check the head unit volume.

Check speaker shorts.

Check that crossover frequencies have been properly set.

HIGH HISS-ENGINE NOISE IN SPEAKERS

Check that the minimum speaker impedance is correct.

Check short on power cable and vehicle chassis.

AMPLIFIER IS NOT POWERED UP

Check that there is battery power on the +12V terminal.

Check that remote terminal has at least 13.8V DC remote connection.

Check a good ground connection. Check all fuses.

Check the protection LED is not lit.

Check shorts on speaker wires.

Remove speaker wires and reset the amplifier. If the protection LED still comes on,

then the amplifier is faulty.
