Analogue OperationsFilterThe filter and EQ are both switched in using the EQ IN switch ( 1 ).Turning the HPF pot up from minimum then activates the filter (18dB/Octave high pass). The EQ IN LEDis off when inactive, lights red when the EQ is in circuit but the filter is inactive, and lights green when thefilter is active.2EqualizerThe EQ is activated using the EQ IN switch ( 1 ).The EQ IN LED lights when the EQ is in circuit. Each band has a gain control pot labelled dB (±20dB ofgain, notched at 0dB), and a frequency control with the following ranges:LF: 40Hz - 600Hz.LMF: 200Hz - 2kHzHMF: 600Hz - 7kHzHF: 1.5kHz - 22kHz312High (HF) and low (LF) bands default to a shelve shape. Press each band’s BELL buttonto switch to a fixed Q parametric shape.High-mid (HMF) and low-mid (LMF) bands are parametric, adjust the Q between 0.2 and 2 using eachband’s Q pot.948G-EQ (2) toggles the EQ shape between E-Series and G-Series EQ curves and control interaction.The difference between E-Series and G-Series EQ is as follows:31E Series The bell curves are steeper sided and there is no overshoot on the shelf curve. E Series EQ ismore aggressive and is therefore better for removing problem frequencies.G SeriesThe bell curve has a more rounded shape at low gains and the shelf curve overshoots zeroslightly at the base of the curve. G Series EQ is more subtle and is often considered particularly suited toinstruments and vocals.With the gain at maximum boost or cut both curves are identical.92425.025.020.0'E type'20.0'E type'15.0'G type'15.0'G type"10.0Both10.05.05.00.00.0-5.0-5.010.0-10.015.0-15.020.0-20.025.010 100 1k 10k 20k-25.020 100 1k 10k 100kAWS 948The upper G-EQ switch operates on shelving bands and the lower on parametric bands, as indicated by the symbols tothe right of the switches.The EQ can be switched between channel paths in the Channel Setup screen described on Page 3-4.AWS 924-948 Owner’s Manual Page 3-7
