The bass power amplifier is equipped with an advanced digital sound processor.

The digital crossover eliminates all passive filter elements in the signal path with a precision and bit accuracy that cannot be achieved with analogue technology.

The volume of the subwoofer can be adjusted using the two buttons on the DSP display.

The Avantgarde Control Software allows a wide range of additional settings (e.g. high and low pass filters, equalisers, etc.) to be programmed. The DSP has 2 x LAN sockets, allowing multiple subwoofers to be daisy-chained for simultaneous programming. A USB connection is optionally available.

The user interface has been completely redesigned and is now very easy and intuitive to use. All parameters can be easily adjusted to suit the room acoustics or listening habits.

The BASS-BOOST control can be used to boost the low-frequency response below 45 Hz, allowing the bass response to be adjusted from ‘linear’ to ‘rich’.

The DSP has an 8-band equaliser for individual frequency adjustment. Each of the 8 bands can be raised or reduced by up to 4 dB. This can be used to adjust the bass response to suit a particular sound (linear, techno, pop, rock, classical, etc.) or to reduce certain broadband room resonances.

The LPF-RANGE slider adjusts the upper crossover frequency of the subwoofer and thus the “tonal balance” of the system.

At higher frequency settings, the subwoofer partially overlaps with the midrange horn’s frequency response. This makes vocals/instruments sound ‘warmer’ and ‘fuller’.

When the crossover frequency is set lower, there is a small gap between the subwoofer and midrange frequency response. The tonal balance of the system shifts towards a more ‘dynamic & punchy’ sound.

FILTER 1 & 2 are narrow band ‘notch’ filters with a level cut of -3dB or -6dB. These filters can be used to eliminate/reduce unwanted narrowband room resonance frequencies.
