The E Series EQ Module features two different EQ’s found on editions
of the console produced between 1979 and 1987. Each EQ has unique
response curves and tonal character. They are distinguished by the
colors used on the LF knob caps so the two flavors have become known as
the ‘Brown’ and ‘Black’ EQ’s. On the E Series EQ Module you can switch
between these two different flavors of EQ that have been loved by
generations of professional producers.
- Immortal SSL 4000 E Series circuitry
- “Black-242” and “Brown-02” twin EQ design
- Bell curve option on HF and LF
- Fully parametric LMF and HMF with Q
- Based on classic 611E console channel strip
The ‘Brown’ EQ, featured on the discontinued SSL E-Signature Channel Strip, is now uniquely available on the E Series EQ Module.
A little SSL EQ history
Prior to 1987 SSL used the colour of the Low Frequency EQ knob caps
to indicate which type of EQ was fitted. All consoles were custom built
and could feature different combinations of EQ module. The following
colour codes apply:
E Series BROWN: The original SSL EQ fitted to all consoles
prior to the summer of 1985. Despite the rumours these equalisers only
came in one version. The EQ card was called the ‘02’.
E Series ORANGE: The infamous EQP equaliser. This was a
variation on the Brown EQ with controls simulating the curves of a
valve type EQ. Very few were sold. This card was named the ‘132’.
E Series BLACK: The last version of the standard E series EQ.
It evolved in the early 1980’s from discussions with many top engineers
and proved very popular.
The EQ card was called the ‘242’.
G Series: With the arrival of the G Series console in 1987
the colour coding was abandoned and the classic SSL end cap colour
scheme used today was adopted. First introduced in 1987 the original G
Series EQ introduced Q characteristics which were proportional to gain
settings and had a degree of over shoot when boosting and under shoot
The current generation of SuperAnalogue console EQ (featured on
Duality, AWS 900 + SE & the X-Rack EQ module) are switchable
between EQ characteristics that offer either the E Series ‘Black’ EQ or
the G Series EQ.
