CONTROL DESCRIPTION
CHAPTER 2
The 1976 has been laid out to be as intuitive as possible. Essentially the layout of the 1976 comprises an input control
to the left of the unit, after this the stereo signal is split into identical low, mid and high bands of saturation and width,
each one processed separately at different frequencies without affecting the other, with the crossover frequency controls in betwee
. The audio is then summed back into a stereo signal again before output, located to the right of the unit (see
below diagram).
INPUT
(1a)
INPUT LEVEL TRIM:
OFF - +15dB
Typically, the Input Trim level control is used to match the output of the preceding
device to the input needs of the three saturation bands that the signal will pass
through.
(1b)
METER:
The meter shows the effect of the input trim on the signal level to the saturation
bands.
The input control sets a balance between the incoming signal level and the amount (or drive) of saturation that
occurs.
Set the input control so that the central yellow led is lit the majority of the time and the Red LED
only on the very highest signal peaks.
This is the optimum balance between gain and saturation. If the input trim
is set too low (the green led) little saturation will occur. Alternatively, increasing the input trim control pushes more
level into the saturation circuitry and therefore more saturation occurs. However, set the input control too high (the
red led) and, as saturation is also a form of dynamic control, the overall gain level is attenuated as the audio
becomes more distorted.
X-OVER FREQUENCIES
The 6dB per octave crossover frequencies determine the
points within the frequency spectrum that one band stops
processing audio, and another band takes over.
(2a)
LOW X-OVER FREQUENCY:
70Hz - 1.5kHz
Sets the frequency point at which the split between low
and mid bands occurs.
(2b)
HIGH X-OVER FREQUENCY:
800Hz - 15kHz
Sets the frequency point at which the split between mid
and high bands occurs.
