    The E-Series EQ 500 series module reproduces the legendary sonic signature of an early 80's classic, the equalizer section of the Solid State Logic SL 4000 E console channel strip, which has featured on countless classic recordings from the 1980's to the present and shows no sign of stopping. The 611 design E-Series EQ also feature on Solid State Logic's latest audio production console, ORIGIN.

     

    Solid State Logic E-EQ Mk2 500 Series Equalizer Features:

    • Immortal SSL 4000 E Series circuitry
    • "Black-242" and "Brown-02" twin EQ design
    • Versatile 4 band channel EQ
    • Bell curve option on HF and LF
    • Fully parametric LMF and HMF with Q
    • Based on classic 611E console channel strip

     

    Unique response & tonal character

    The E-Series EQ Module features two different EQ's found on editions of the console produced between 1981 and 1989. Each EQ has unique response curves and tonal character. Historically the type of EQ fitted in an individual console was distinguished by the colours used on the LF knob caps so the two flavours have become known as the 'Brown' and 'Black' EQ's. On the E Series EQ Module you can switch between these two different flavours of EQ that have been loved by generations of professional producers.

     

    ‘Brown Knob’ EQ

    With the BLK button out, the two parametric mid-band sections feature SSL’s classic logarithmically symmetric design ensuring that the ±3dB up/down points retain the same musical interval from the center frequency regardless of frequency and amplitude settings. The two shelving sections are traditional 6dB/octave designs with an option for a fixed Q parametric response (by way of the BELL button). The ‘02’ EQ, to give it its correct name, was used on countless recordings and mixes in the early eighties.

     

    ‘Black Knob’ EQ

    In the mid-eighties a new ‘242’ EQ circuit was developed in conjunction with the legendary George Martin for the first SSL console to be installed in AIR studios. The ‘Black Knob’ EQ, as it became known, featured enhanced cut and boost ranges (±18dB instead of ±15dB) together with a different control law for tighter control of low frequencies. It is this design which is retained today as the ‘E Series’ EQ option of the Origin, AWS 924, AWS 948 and Duality consoles.
