Console OperationsFiltersThese comprise a 3rd Order18dB/Octave high pass filter (lF) and a 2nd Order 12dB/Octave lowpassfilter (HF). Each filter is out of circuit when the control is fully anticlockwise. When the filter isin circuit, the FIlter box on the channel TFT display is highlighted.Normally, the filters follow the EQ section in the signal chain but the FIlt to Inp button in theinput section of the channel strip places the filters directly after the channel input. This function is also available on the centralrouting panel. Pressing tO s/ch routes the filter section to the dynamics sidechain.Signal processing order is graphically displayed on the channel TFT screenequaliserThis is a four band parametric equaliser based on SSL’s classic 'Black Knob' EQ, which was developedfor the original SL 4000 E Series console. Selecting the G-eQ button introduces steeper shelvingcurves with a controlled amount of undershoot/overshoot at the turnover frequency, together withthe classic gain/bandwidth interaction for the mid band sections that was a key characteristic of theoriginal G-Series EQ.The individual bands function as follows: HF high frequency shelving equaliser switchable to fixed Qparametric (BELL); HMF high frequency parametric mid band equaliser; lMF low frequencyparametric mid band equaliser; lF low frequency shelving equaliser switchable to fixed Q parametric(BELL). The eQ In button (located next to the insert buttons) routes the channel signal through theEQ and filter section. When in circuit, the eQ box on the channel TFT display is highlighted. See alsoCentral routing Control.Inserthighlighted.The Ins In button routes the channel signal via balanced insert send and returnpoints, available on the rear of the console (D-connectors). The insert defaults to thechannel input (post the input trim); pOst cycles the insert position through twoalternative locations in the processing path: post EQ or post Dynamics; the centresection master routing panel provides individual Ins pOst eQ and Ins pOstDYn buttons.
