E.Q.

LOW BAND

Frequency:

This continually variable control sets the centre frequency where the signal is boost/cut. As it's completely

variable it allows you to sweep the signal to pin point problematic frequencies providing greater flexibility and

accuracy than lesser equalisers.

Slope:

Sets by how much or 'fast' the signal is attenuated in dB's per octave at the Low frequencies. For example, a

6dB per octave Low slope located at 100Hz would accomplish 6dB of attenuation at 50Hz, and 12dB at 25Hz

and so on until the signal is fully attenuated. 6dB per octave is more gentle and therefore more musical than

12dB, however, at 12dB per octave the signal is 'focused' but attenuation more noticeable.

The Peak setting adds a narrow bell shaped boost to the 12dB per octave low band filter at the knee frequency

just before it rolls off. Especially useful on kick drums, it magnifies and gives extra weight to the hit whilst still

filtering out any subsonic junk.

Cut/Boost:

The amount of gain (boost) or reduction (cut) that is applied at the frequencies set within the band. The control

is nonlinear and so is capable of subtle adjustments for mastering or larger variations for tone shaping.

MID BAND

Frequency:

See Low Band Frequency

Bandwidth:

Bandwidth is defined as the range of frequencies (width) centred around that set by the frequency knob allowing

you to attenuate or boost a very narrow or wide range of frequencies within each EQ band.

On the 1977 the width of the effected signal is measured as Bandwidth (as opposed to 'Q', which it is inversely

related to) and on the Mid band is fully parametric (as opposed to semi, quasi or fixed that you may find on

other eq's) meaning that the bandwidths are fully adjustable across their entire range, providing greater control.

Cut/Boost:

See Low Band Cut/Boost

HIGH BAND

Frequency:

See Low Band Frequency

Slope:

Sets by how much or 'fast' the signal is attenuated in dB's per octave at the High frequencies. 6dB per octave

is more gentle and therefore more musical than 12dB, however, at 12dB per octave the signal is 'focused' but

attenuation more noticeable.

Cut/Boost:

See Low Band Cut/Boost

Overload LED's

Inbetween each E.Q. band is an overload LED that illuminates to indicate that the E.Q. section has too much

overall gain in total and one, or a combination of the three cut/boost controls should be reduced.

E.Q. Switch

A fully hard-wired bybass switch toggles the E.Q. section to be active or not, and is best used for A/B comparisons,

or to remove the E.Q. stage from the signal path altogether.
