USER MANUAL
iA240X/iA360X
Power amplifier
06
Operation
Rear panel operation
GROUND LIFT SWITCH
To eliminate a ground loop, set ground switch to FLOAT position and otherwise
to connect a ground to amplifiers chassis.
INPUT GAIN CONTROL
This control allows 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 -80 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.
HP FILTER SWITCH
HPF reduce low frequency in audio signal.
COOLING VENTS
Cool air is pulled in through the front panel fan filters and eliminated through
the rear panel vents.
BALANCED XLR INPUT
Connect audio signal to electronically balanced XLR. Please note that the
iA240X iA360X needs at least 0 dBu to achieve maximum power.
LINK OUTPUT
Connect outgoing audio signal from balanced XLR connectors to additional
amplifier. Input and link connectors are connected with each other directly.
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 un-
available. 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.
PHOENIX OUTPUT
Use this connector to connect amplifier to the loudspeakers.
AC FUSE HOLDER
Please use 3,15A, 250V fuse for amplifier iA240X and 4A, 250V fuse for amplifier
iA360X
MAIN POWER CONNECTOR
Power connector is designed for main powers connecting to amplifier. This
connector is combined with fuse holder.
