fall into liquids and liquids would not be spilled on the device.
3 Use this device when you are sure that it has a stable base and it is xed securely.
4 This product, in combination with loudspeakers may be capable of producing sound
levels that could cause permanent hearing loss. Do not operate for a long period of
time at a high volume level or at a level that is uncomfortable. If you experience any
hearing loss or ringing in the ears, you should consult with otorhinolaryngologist.
5 The product should be located away from heat sources such as radiators, heat vents,
or other devices that produce heat.
6 Note for power connections: for pluggable equipment, the socket-outlet shall be
installed near the equipment and shall be easily accessible.
7 The power supply should be undamaged and never share an outlet or extension
cord with other devices. Never leave device plugged into the outlet when it is not
being used for a long period of time.
8 Power disconnection: when the power cord connected to the power grid is
connected to the machine, the standby power is turned ON. When the power switch
is turned ON, the main power is turned ON.The only operation to disconnect the
power supply from the grid, unplug the power cord.
9 Protective Grounding - An apparatus with class I construction shall be connected to
a power outlet socket with a protective grounding connection.
Protective Earthing - An apparatus with class I construction shall be connected to a
mains socket outlet with a protective earthing connection.
10 The lightning ash with an arrowhead symbol, with an equilateral triangle,
is intended to alert the user to the presence of uninsulated dangerous
voltage’within the products enclosure that may be of sucient
magnitude to constitute a risk of electric shock to persons.
11 The exclamation mark within an equilateral triangle is intended to alert the
user to the presence of important operating and maintenance (servicing)
instructions in the literature accompanying the appliance.
12 There are some areas with high voltage inside, to reduce the risk of electric shock
do not remove cover of the device or power supply.
The cover should be removed by the qualied personnel only.
13 The product should be serviced by qualied service personnel if:
– The power supply or the plug has been damaged.
– Objects have fallen into or liquid has been spilled on the product.
– The product has been exposed to rain.

Front panel functions
LED INDICARTORS
THE SIGNAL INDICATOR illuminates when indicates an audio signal in the
amplier's input.
LIMITER INDICATOR - the amplier has a built-in audio signal limiter in order to
limit output power. In case if input audio signal exceeds the maximum amplitude
needful to achieve maximum power, the audio limiter reduces the audio signal level
to a safe value and indicates activity using LIMIT LED.
MUTE INDICATOR illuminated when mute function is activated. The red LED
indicates muted channel.
POWER BUTTON
Switch amplier power ON or OFF.
LCD DISPLAY
LCD screen displays main information about ampliers: volume level, tone
controls levels, muting, locking, stand by status or sync settings.
ROTARY ENCODER
Designated to adjust amplier parameters. Rotate the encoder to adjust
parameters and push it to enter the menu or sub-menu. Press and hold for a
second to return the default screen. Push rotary encoder shortly to select CH1
or CH2, hold it to activate the selected channel menu. In order to disable LOCK
mode press and hold the encoder for 5 seconds. Turn or press knob to get back
device from standby mode.
Rear panel functions
MODE SWITCH (iAC 2X240)
Amplier can be set to operate in 2 modes: 2 controllable channels or single
channel mode. Both selections can operate in 100 V line.
STEREO RCA & BALANCED PHOENIX INPUTS
RCA input for line level audio.
AMPLIFIER OUTPUTS
Audio outputs for 4 Ω, 70 V, and 100 V speaker lines. Only one output can be
used at the time. Operating amplier with more than one output may cause
damage the amplier or connected speakers.
RS232 SERIAL INTERFACE
Designed to control main function of iAC apliers by using serial interface.
RS232 protocol is listed in page 8.
RESET BUTTON
This button resets all amplier parameters to default values. To activate this
function, press and hold button for two seconds.
