5. SSL Console EQ and Filters | SSL Console Bundle for MX4 |

The High Mid Frequency section operates over a frequency range of 600Hz - 7 kHz and is capable of ±20dB of gain with a continuously variable Q from 0.5 to 2.5.
Normally, at any Q setting, the bandwidth of the HMF and LMF sections varies with gain, whereby an increase in boost or cut increases the selectivity of the EQ.
This type of EQ can sound effective when used at moderate settings; the gentle Q curve lends itself to the application of overall EQ on combined sources and subtle corrective adjustments to instruments and vocals.
When the EQ is switched to ʻEʼ operation, the bandwidth of the HMF and LMF sections remains constant at all gains, so at lower gains the EQ curves are comparatively narrower for a given Q setting.
This is particularly useful for drums, since relatively high Q is available at low gain settings.
The filter section of the SSL Console EQ and Filters
The low pass filter operates from 3kHz to 22kHz and the high pass filter operates from 20Hz to 500Hz. In addition, each filter has an OUT position which bypasses the filter.
The filter section can be placed in two different places in the signal chain; post or pre equaliser. When the INPUT button in the filter section is pressed, the filters are placed before the equaliser section.
When the INPUT button is pressed, the filters come after the equaliser section.
However, it is not so suitable for overall EQ or subtle corrections, as you need to adjust the Q to maintain the same effect when the gain is changed.
