Functions description

HANDLES

For easy transport while carrying, or while rack mounting, the amplifier features two handles located

conveniently on the left and right sides of the front panel.

COOLING VENTS

Cool air is pulled in through the front panel fan filters and eliminated through the rear panel vents.

CLIP LED

Lights whenever the channel is outputting signal at full strength and signal is distorted. Reduce signal level

to ensure undistorted output signal.

PROTECTION LED

This LED lights up for approximately one second after the A4X120D is powered on and then turns off if the

amplifier is not damaged. This LED also lights when overheating or other severe problems occur. It is

normal for the protection LED to fade slowly when the amplifier is powered off.

SIGNAL LED

LED in the front panel indicates audio signal of the corresponding channel.

POWER SWITCH

Use this switch to power on or off the amplifier. The LED in the front panel lights up if the amplifier is

powered on.

POWER CONNECTOR

Power connector is designed for main powers connecting to amplifier. This connector is combined with

fuse holder and 4A, 250V fuse.

PHOENIX OUTPUT

Use these to connect each channel with A4X120D to 4 Ω or 8 Ω loudspeakers, or to one of the 70 and 100

volt outputs if you are using a constant voltage system.

BALANCED XLR INPUT

Connect audio signal to these electronically balanced connectors. Please note that the A4X120D needs

atleast 0 dBu to achieve maximum power.

LINK

Connects outgoing signals from these XLR connectors. Input and link connectors are connected with each

other directly.

HIGH PASS FILTER

HPF filter reduce low frequency is in the audio signal.

LEVEL CONTROL

These controls allow you to precisely adjust the input level of the signal arriving at the rear-panel input

connectors. At their fully counterclockwise position, the signal is attenuated by -12 dB. At their fully

clockwise position, the signal is no attenuated. When 0dBu of signal arrives at the input and the input level

controls are set to their fully clockwise position (0dBu), the Amplifier delivers full power.
