Dual-channel thirty-band third-octave graphic equalizer with long-throw, forty-five millimetre faders, two high- and low-pass filters per channel, and two-notch filters per channel. All production units share a sonic consistency, allowing engineers all over the world to replicate their favourite settings on locally sourced machines. Aside from the main filters, the unit sports two high- and low-pass filters per channel, and two-notch filters per channel. Low and high frequency limits can thus be set-up for the system, while the notch filters with 18dB/octave slopes can be used for precise removal of problem frequencies with minimal effect on the rest of the program material. The unit utilizes proportional-Q filtering, which varies the "Q" value depending on the depth of either the cut or boost of a particular band. This results in a smooth and musical response, while still preserving the original source material. Both inputs and outputs are balanced. The internal power supply automatically adjusts itself to various voltages, from 100 to 240VAC.
