The Electra is a 5-band stereo equalizer allowing precise, musical control over tone and texture. The unit is a combination of four meticulously tune filter types featuring a subtly resonant butterworth high-pass, baxandall low shelf, two proportional-Q mids and a mastering style high shelf.

The Electrified Transient Equaliser or ELECTRA is available in the 500 Series format and two channel 19” Rack version. Both units are the same design, though the 19" version has a dedicated power supply and more metalwork, but both are the same EQ circuits.

The ELECTRA EQ has been joint designed by Gregory Scott and another talented designer Brad McGowan who designed the HF and LF Shelves and is split into 5 overlapping bands. Firstly there is a ‘ subtly resonant butterworth ’ high pass filter that is sweepable between 25 Hz and 400 Hz. Then there are the semi-parametric bands that go from 30-730 Hz and 250-5300 Hz, the HF is shelving from 3.8kHz and the Low Shelving is a fixed frequency at 90Hz. The design is not too dissimilar to the API 550a Proportional-Q type design, which means the bandwidth of each frequency changes with amplitude. i.e.. The ELECTRA bandwidth is broad at lower gain settings and gets narrower as the gain increases, so this is one very musical sounding EQs.
