8.2) User settings: Gain

1) OVERVIEW

Gain is generally described as the 'input volume' of a signal going into a circuit like a mixer

or a pre-amplifier.

In the context of the ADE-60 this setting refers to the increase in volume, or the 'gain',

in amplitude of that signal between the input and the output.

This user setting can increase the output of a signal by up to 2x – i.e. up to 2x Gain.

When this setting is activated, at full volume, a +/-5V AC waveform will output at +/- 10V,

a +5V DC input will output at +10V and a -5V DC input will output at -10V.

When this setting is activated, the volume knob at the fully counter-clockwise (fully left) position outputs

silence (100% attenuation), rotating clockwise to the 12 o'clock (middle) position outputs 'unity gain'

where the volume of the output equals the volume of the input and a fully clockwise (fully right) knob

position outputs a signal that is twice the amplitude (for AC waveforms) or twice the voltage

(for DC voltages) of the original input signal.

The Gain user setting is activated via the 3-pin header on the rear PCB that is marked 'Gx'

where 'x' is the channel number e.g. the header marked G2 is the Gain header for channel 2.
