Functions description
PROTECT INDICATOR
This LED lights up for a few seconds after the iA 480X is powered on and then turns off if the amplifier is
not damaged. This LED also lights when overheating or other service problems occur. It is normal for the
protection LED to fade slowly when the amplifier is powered off.
SIGNAL CLIPPING INDICATOR
Lights whenever the channel is outputting signal at full strength and signal is distorted. Reduce signal level
to ensure undistorted output signal.
SIGNAL INDICATOR
LED in the front panel indicates audio signal of the amplifier.
POWER INDICATOR
This LED indicates status of the main power. The LED lights up if the amplifier is powered on.
POWER SWITCH
Power switch is hided with cover to prevent illegal or incidental use. Remove cover using Phillips
screwdriver and use this switch to power on or off the amplifier. The power LED in the front panel lights up
if the amplifier is powered on.
COOLING VENT
Cool air is pulled in through the front panel fan filters and eliminated through the rear panel vents.
VOLTAGE SELECTOR
This switch is used to set the input voltage to the power supply. Setting the power supply voltage switch to
the incorrect input voltage could damage the amplifier. The correct voltage is determined by the country
where the amplifier will be used
MAIN POWER CONNECTOR
Power connector is designed for main powers connecting to amplifier. This connector is combined with
fuse holder.
HOLDER FOR AC FUSE
Please use 5A, 250V fuse if amplifier is used in ~230V 50Hz electricity system and 10A, 250V fuse if amplifier
is used in ~115V 60Hz system.
LINK FOR DC 24V
POWER SUPPLY
This connector is designed to link the DC 24V power to additional amplifier. DC IN and DC LINK connectors
are connected with each other directly, inside the amplifier.
INPUT FOR DC 24V
POWER SUPPLY
This connector is designed to power up amplifier when the main power is unavailable. Use only 24V
power supply or batteries and take attention to polarity during the wiring. If both, AC and DC power are
connected, amplifier will use main AC power.
AMPLIFIERS OUTPUT
Use this connector to connect amplifier to the loudspeakers.
GROUND LIFT SWITCH
To eliminate a ground loop, set ground switch to FLOAT position and otherwise to connect a ground to
amplifiers chassis.
LINK OUTPUT
Connect outgoing audio signal from stereo RCA and Phoenix connectors to additional amplifier. Input and
link connectors are connected with each other directly.
