Power On

Power on the unit by moving the rear panel rocker-switch into the on position. The start-up sequence will run, concluding with the
+48V LEDs blinking for a few seconds (if active) as the unit returns to its previous state.

OCTO has 8 channels of preamps, with an identical set of controls for each one.

GAIN
11-position stepped control provides +5 to +65 dB of gain for microphone sources (in 6 dB steps) and 0 to +30 dB of gain for Line
sources (in 3 dB steps). In Hi-Z mode, the gain range is +11 dB to + 41 dB in 3 dB steps.
TRIM
31-position stepped control provides ± 15 dB gain in 1 dB increments. This is a separate gain circuit, post the main GAIN.
Top tip - overdrive the signal with the GAIN control and then reduce to a suitable level using TRIM, so as not to
overload equipment downstream of the preamp or the analogue to digital converter.
HPF (High-Pass Filter) LED
A 3rd order / 18 dB per octave high-pass filter at 75 Hz can be engaged/disengaged from the signal path by a short press on the
TRIM control.
