1-Channel/Mono Amplifier Applications

AX 1600D / AX 2400D / AX 3200D / AX 4000D

Mono Subwoofer (Link-Mode,2-Mono Amplifier)

MASTER-Amplifier

SUBSONIC - Eliminates the lowest frequencies to protect the speakers from damages. These low frequencies can cause

damages. The frequency is adjustable from 15 Hz up to 35 Hz.

LOW PASS - This eliminates the higher frequencies.Set the crossover-frequency between 50Hz-100Hz,

depending on the size of the installed speakers.

BASS EQ - Allows you to adjust the bass boost from 0dB up to 18dB

Caution! Please use the Bass - EQ carefully. The additional boost may result in clipping or overload.

PHASE SHIFT -This allows you to match the Phase 0° to 180°. So you can integrate each subwoofer

INPUT LEVEL

• Turn the INPUT LEVEL control on the amplifier to 5V position.

• Turn the head unit volume control to about 80-90% of its full setting.

• Turn the INPUT LEVEL control clockwise until you hear some distortion.

• Turn back the INPUT LEVEL control slightly until you can hear clean sound.

MASTER/SLAVE - set on "MASTER"-Position

SLAVE-Amplifier

MASTER/SLAVE -set on "SLAVE"-Position

All functions of the slave are controled by the master amplifier

Interconnections

• Connect the head unit (Radio) with the INPUT L&R of the first Amplifier.

• Connect the MASTER OUTPUT of the first Amplifier (MASTER) with the INPUT SLAVE of

the second Amplifier (SLAVE).

• Connect Remot control with the Master Amplifiere

• Connect Remote from Master with Remote Slave and then connect it with your head unit

• Connect the LINE INPUT of the amplifier to the head unit line output with good quality RCA

to RCA cables.

• Connect the speakers with the terminal block (SPEAKER OUTPUT/ - LEFT + and - RIGHT

+) of the amplifier.

• The minimum final speaker impedance must not be below 2 Ohm per channel. Too low

speaker loads result in too high heat dissipation and may cause the amplifier run into

protection.

• Please observe speaker channel and polarity as printed by the speaker terminal

block.Incorrect phasing of the speakers results in total loss of bass response.

Be careful not to connect speaker (-) to the ground or vehicle chassis.

Caution!
