The model is equipped with a balanced XLR input and an unbalanced RCA input, which is duplicated by a similar RCA output. On the back panel there is a slider selector switch that allows you to select the desired pair of connectors (RCA or XLR), as well as switches for selecting one of the gain values (25 dB or 31 dB) and for activating one of the operating modes: stereo, bridge mode or "dual mono".
The amplifier develops a power of 4 x 50 Watts at 8 ohms in the AB class and is designed mainly for voicing the upper channels when operating in 7.1.4 Dolby Atmos and DTS systems.:X or Auro-3D, although it can be successfully integrated into a multi-room audio system.
