CONTROL DESCRIPTION
CHAPTER 2
The genuine stereo linked operation of the 1974 makes adjustment quick and extremely simple using just one set of
controls to alter both channels. The 1974 uses precision potentiometers, each one being matched for left/right accuracy
to within fine tolerances by our trained technicians, so that both channels operate identically, and also have 21 position
indented operation, providing exceptional accuracy for fast and simple recall.
INPUT
INPUT GAIN: -15dB - +15dB
Typically, the Input Gain control is used to match the output of the preceding device to the
input needs of the four e.q. bands that the signal will pass through.
If the input is too low the signal of every e.q. band will need to be boosted just to reach the
optimum output level. If the input is too high every band will have less headroom to boost
the signal before clipping occurs.
LOW CUT
FREQUENCY: 10Hz - 225Hz
This continually variable control attenuates the signal below the frequency set. The rate
at which the attentuation occurs is set by the ‘Slope’ control (see bellow). Use it to
remove extraneous content at the lower end of the audio range such as mechanical
rumble or to tighten the mix.
IN:
This Bypass switch, when pushed in will illuminate the LED, indicating that the Low Cut
Filter is in circuit.
LOW
FREQUENCY: 35Hz - 700Hz
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: 6dB / 9dB / 12dB / PEAK
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 Cut 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 noticable.
The Peak setting adds a narrow bell shaped boost to the 12dB per octave low cut 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: -12dB - +12dB
The amount of gain (boost) or reduction (cut) that is applied at the frequencies set within the band. The
control is non-linear and so is capable of subtle adjustments for mastering or larger variations for tone
shaping.
