axxent AX4240TS-D Professional 4 channel Power Amplifier With Dante

IMPORTANT INFORMATION

The professional audio amplifiers of the axxent TS series are optimised for use in fixed installations. The 4-channel model AX4240TS-D complements this series with an output power of 240 W/channel and 480 W mono bridged per pair. In addition to the analogue inputs, this model has a Dante digital input for easy networking. The switching power supply saves weight and increases efficiency and power balance.
Each of the 4 channels offers an independent clip limiter with separate indicators on the front panel. Excellent audio quality throughout the power range is supported in the inputs by special balanced integrated circuits with high common-mode rejection.
In addition to the constant voltage outputs with 70 and 100 V taps, low- impedance outputs are also available. Galvanic isolation by means of high- quality audio output transformers enables earth-fault monitoring and serves to protect the 100 V lines against accidental contact.

The rated output power is 240 W into 100 V and 4 ohms, or 170 W into 8 ohms per channel. These flexible output configurations make the AX4240TS-D 4-channel amplifier the ideal choice for use in fixed installations. The four amplifier channels can be operated individually or in
bridge mode (2×470 ohms and 8 ohms) for power bundling. The only adjustment elements on the front panel are the input level controls. To protect against unintentional or unauthorised adjustment, the control knobs can be removed and replaced with the supplied blanking plugs.
The connections – inputs: analogue balanced XLR and digital with Dante compatibility. Analogue/digital switching is individually selectable for all four channels. All output sm, low impedance and 70 V/100 V, have 10-pin Phoenix screw terminal connectors. Mains voltage input via IEC connector. The robust housing is made of reinforced, powder-coated sheet steel. CE certification for Europe-wide use.
