Final answer:
On the Neotek Elite, when the REV button is up, the output of the fader (large) goes to the auxiliary send bus.
Step-by-step explanation:
On the Neotek Elite, when the REV button is up, the output of the fader (large) goes to the auxiliary send bus. The auxiliary send bus allows the audio signal to be routed to external effects processors, such as reverbs or delays. By sending the audio to the auxiliary bus, the engineer can control the amount of effect applied to the signal using the auxiliary send knob. On the Neotek Elite mixing console, when the REV (reverb) button is in the up position, the output of the large fader routes to the main mix or the mix bus without any involvement of the built-in reverb. Essentially, with the REV button up, the signal from the fader proceeds directly to the main output without being sent to the internal reverb unit. This configuration allows for a dry signal without the addition of reverb effects. Engaging the REV button would send the signal through the reverb unit, but with it up, the fader's output remains unaffected by the internal reverb processing.
