Attention:

 Do not cover vents.

 Check that there is no damage to the power cable before use

 Do not position near heat sources, in direct sunlight or moisture and allow adequate ventilation and cooling space.

 Power supply must be earthed properly

 Ensure that the power supply is the correct voltage and capable of delivering adequate current safely.

 If the amplifier enters PROTECT mode, switch off immediately and check all connections, only re-connect after the

problem is resolved or otherwise refer to a qualified service technician

 Take care to avoid injury through contact with the high voltage 100V or 70V terminals

 Choose EITHER 100V or 4-16Ω output – DO NOT MIX THE OUTPUTS

Installation:

 The A120TUD is 2U 19” rack-mountable and should be located in a safe, dry, well ventilated position.

 Connect all inputs and speaker outputs prior to powering up.

 Composite video can be fed to a screen or projector from either of the 2 RCA “VIDEO” connectors at the rear

 The fire alarm contacts at rear should be connected to the building’s fire alarm panel which feeds a line level signal

when the alarm is triggered, muting the output of the A120TUD to allow the alarm to be heard.

 Some microphones require phantom power to work, check and switch on the “+48V” to the XLR if needed

 Choose whether the system will operate at 4-16Ω or 100V.

 If not 100V, ensure that the overall impedance is no lower than 4 Ohms (note: 2 x 8Ω parallel = 4Ω)

 If 100V line, ensure that the total power tapped from all speakers does not exceed 90% total amplifier output

 Connect all speakers in parallel to each other then lastly connect the amp in parallel

 Connect the “-“ (negative, cold) wire from the first speaker to “COM” (common connection)

 If not 100V, connect the “+” (positive, hot) wire from the first speaker to “4-16Ω”

 For 100V line systems, connect the “+” (positive, hot) wire from the first speaker to “100V”

 Before switching on, turn all volume controls down and increase gradually after powering up.

 Check each channel in turn by gradually increasing the relevant volume control

 When the “1dB” indicator illuminates persistently, the output is overloading and overall volume should be reduced

via the Master volume or the Mic or Aux channel volume controls

 Turn up the “MP3” level part way and insert a USB device containing appropriate media into the USB connector

 Use the transport instructions below to navigate the USB media or alternatively, tune into FM radio

 Press the eject “” button for the CD/DVD player, place CD or DVD in the tray and press “” again to close

 Select play for the CD/DVD player and gradually increase the “CD” volume control to test

USB/FM Operation:

 selects Play or Pause

 selects previous track or station

 selects next track or station

 MP3/FM switches between USB and FM tuner.

CD/DVD Operation:

 open or close disc drawer

 selects Play or Pause

 selects previous track

 selects next track
