CONTROLS ON THE FRONT

1: You will recognise four buttons on the left front. These

are the gain controls for the four channels of the am-

plifier. The gain controls are also commonly referred

to as volume controls. The gain controls can be ad-

justed with control knobs or, for safety, covered with

the blind plugs supplied with the amplifier. Of course,

the potentiometer knobs must be removed first.

2: Each gain control has three LED indicators - green,

green and red. The lower LED only indicates the

operation of the power amplifier - when switched on.

The middle green LED indicates that an input signal is

present. The upper red LED indicates that the maxi-

mum input level has been exceeded and that the

automatic limiter (signal limiter) is engaged.

3: To the right of the level controls you will find another

three-stage LED display, yellow, yellow, red. The two

yellow LEDs at the bottom indicate bridge operation of

channels 1+2 and 3+4. This so-called bridge mode serves

to double the power when the channels are operated in

low-impedance mode, i.e. with the AX-4120TS-D: 2x120

W result in about 240 watts. Realistically, you can expect

200 to 220 watts. With the AX-4240TS-D: 2x240 W

result in 480 watts, but again, please calculate only with

about 400 watts with the AX-4240TS-D. This power is

then available at 8 ohms. This will be described in more

detail later.

The upper red (Protect) LED indicates the self-protection

of the amplifier. When this LED is on, you will no longer

hear any sound, as the amplifier has switched off and

can only start up again after the fault has been rectified.

Please call the technician!

Additional controls on the front of the AX-4120TS ampli-

fier were deliberately omitted to prevent operating errors.
