PASO AXF240-HV 240W amplifier mixer with 4 KV isolation

240W amplifier mixer with 4 KV isolation

The peculiarity of these amplifiers consists in their ability to withstand the presence of high voltages between network supply/speaker outputs and chassis, which can reach up to 4 kV. This feature increases the safety of the system, preventing a possible discharge on the network or speaker connections from going up the audio chain and therefore causing serious damage to property or people.

The integrated amplifier is made in the standard format that allows it to be mounted even inside telephone-type cabinets. The possibility of being attached directly to the wall, using the appropriate support plate, allows it to be applied in all situations marked by a lack of space.

The amplifier input is electronically balanced; for special needs such as, for example, in the case of connection lines that are particularly long or subject to disturbances, it is possible to galvanically isolate the input using the optional TM92 board, equipped with a line transformer.

The amplifiers are equipped with a diagnostic card capable of offering a large number of additional functions (line impedance measurements, amplifier diagnostics, verification of the integrity of the speaker line, volume control, selection of two inputs, relay control for fault signaling, possibility of inserting the 'LOW CUT' filter, operation in 'LOW POWER' energy saving mode).

In addition to performing all the operations and/or checks set locally with the microswitches, it will be possible to view and modify all the parameters through the RS485 serial interface.

The AXF120-HV and AXF240-HV models have four inputs with RJ45 jacks available on the lower panel: one input for the B711-G microphone station (BASE) and 3 auxiliary inputs (AUX1, AUX2 and AUX3). These electronically balanced inputs are switched between them and are provided with priority to scale: the BASE input has priority over the AUX1/2/3 inputs; the AUX1 input on AUX2/3 and the AUX2 input on AUX3. The inputs are switched, on each of them, through a positive power supply coming from outside. On the AUX1/2/3 sockets there is a voltage that is interrupted in the event of a failure or shutdown of the amplifier: this allows you to remotely monitor the operation of the amplifier itself. On the AUX 2 and AUX 3 sockets, there is a 'busy' signal when the BASE input or the AUX1 input are active.
