A2TI is a powerful 2 channel class D amplifier (PFC and SMPS power supply) with 4- poles speakON outputs. The user can choose between BRIDGE, PARALLEL, or STEREO MODE. The balanced inputs, with sensitivity selector, can be linked to create a more complex amplifiers network. It can cover a wide range of applications, expecially in fixed installations.

Power switch - Lights at the action of all the protection circuits - Lights when compression/limiter is protecting the amplifier - Lights when the output signal is around -5 dB than full power. - Lights when the output signal is around -10 dB than full power. - Lights when the output signal is around -20 dB than full power. - Lights at the presence of input audio signal - Lights when the amplifier turn on ON SIGNAL LIMITER PROTECT -20dB -10dB -5dB CH2 0dB 0dB 00 - Attention! Touching uninsulated OUTPUT CHANNELS or bare wiring may result in an unpleasant sensation. Don’t touch uninsulated OUTPUT CHANNELS or bare wiring when power on.

• Connect the passive loudspeakers, using cables with speakON connectors (4-5 outputs), depending on impedance, max rated power, and amplifier mode. Select the amplifier MODE (5). • Connect the inputs, using balanced cables with XLR connectors (6-7 input). Select the inputs sensitivity (4). • If needed, link the input LINK connectors, to relaunch the signal to a second amplifier. • Set the level knobs (8, 9) to the minimum level. • Connect the mains cable (socket 1), turn on the amplifier (11). • Adjust the level knobs (8, 9), while the audio signal comes from your source. INPUT SENSITIVITY / OUTPUT MODE The user can select the input sensitivity and the output mode of the amplifier. The input sensitivity can be selected from (0.775 V, 1 V, 32 dB), depending on the charaterisctics of the source. The amplifier can operate in three different modes: - brigde (combines two input signal into one output signal to reach a higher power rating) - parallel (route one input signal two both the outputs) - stereo (the default mode, CH1 input is routed in CH1 output, CH2 input is routed in CH2 output) See the upper table and the main tech specs for a further explanation.
