It is a 2-channel Class-D amplifier with 2 x 130 W RMS into 8 ohms and 2 x 250 W RMS into 4 ohms. Externally, it retains the particularly compact dimensions of the previous model, with a standard 19\" rack width and 1U height (44 mm). Internally, however, the layout has been completely re-engineered to improve reliability and heat dissipation; to this end, three fans are used to keep the temperature controlled. The design is based on the use of an extremely efficient soft-start switching power supply. There are three operating modes: stereo, mono, or bridged. Stereo mode is the conventional mode where both channels work separately. Mono mode is basically identical to stereo mode but with the inputs of both channels linked so that the output will be mono; in this case, only the LEFT channel input can be used to drive both output channels with the same signal. Finally, bridge mode bridges the final stages for a power of 500 W into 8 ohms. A peak limiter prevents signal distortion, while a low-cut filter cuts low frequencies at 75 Hz with a very steep 24 dB\/oct filter. The input sensitivity is variable between three values: 0.775 V \/ 1.0 V \/ 1.44 V to adapt to any source. There is also a rear switch for floating ground.\u003c\/p\u003e\n\n\u003cp\u003eTo prevent unauthorized persons from changing the input levels, a plastic cover (included) can be installed with 4 screws in front of the front controls.\u003c\/p\u003e\n\n\u003cp\u003eThe amplifier inputs are balanced XLR, there is a link output for connecting another power amplifier in a daisy chain, while the outputs are on speakON connectors.
