The RPQ160b from Rolls is a single-channel, 4-band parametric equaliser with high- and low-pass filters. The 4 bands have a combined overlapping frequency range of 70 Hz to 20 kHz. The single rack space unit features 3 different input and output connectors to accommodate a wide variety of applications. T filters are used for the equalisation circuits to avoid the complexity and distortion of state-variable filters.

The EQs precise equalisation makes it suitable for many applications, including school or church gymnasiums, home or professional recording studios, live sound or the EQing of musical instruments. When coupled with a spectrum analyser, the RPQ160b can match exactly the properties of typical acoustic resonances and reflections, and make immediate improvements to any installed system's amplitude and phase response.
