9. Phantom Power Switches and LEDs – Pressing and locking the Phan 1-4 switch to the IN position activates +48V phantom power
to rear-panel XLR Inputs 1-4. Pressing and locking the Phan 5-8 switch to the IN position activates +48V phantom power to rear-panel
XLR Inputs 5-8. The switches' associated LEDs light to indicate that phantom power is active for those channels.
10. Channel 1 Instrument Input – Ultra high impedance, unbalanced instrument-level input on 1/4" TS jack.
NOTE: Inserting a TS connector in this input will override any signal present at Channel 1 Mic Input.
11. Channel 1 Instrument Level – Controls the input level of the channel's Instrument preamp. Turn fully counter-clockwise for
minimum gain, fully clockwise for maximum gain.
12. Channel 1 Low Cut Switch – Pressing and locking this switch in the IN position engages the channel's Low Cut filter, attenuating
the Low Frequency signal of 80Hz and below at a rate of 12dB per octave.
13. Channel 2 Instrument Input – Ultra high impedance, unbalanced instrument level input on 1/4" TS jack.
NOTE: Inserting a TS connector in this input will override any signal present at Channel 2 Mic Input.
14. Channel 2 Instrument Level – Controls the input level of the channel's instrument preamp. Turn fully counter-clockwise for minimum
gain, fully clockwise for maximum gain.
15. Channel 2 Phase Reverse – Pressing and locking this switch to the IN position reverses the phase of the output signal on this
channel. This is useful when using two adjacent channels to mic a stereo source.
16. Channel 4 Phase Reverse – Pressing and locking this switch to the IN position reverses the phase of the output signal on this
channel. This is useful when using two adjacent channels to mic a stereo source.
17. Channel 6 Phase Reverse – Pressing and locking this switch to the IN position reverses the phase of the output signal on this
channel. This is useful when using two adjacent channels to mic a stereo source.
18. M-S Matrix Switch and Width Control – Pressing and locking the M-S Matrix Switch to the IN position engages the Mid-Side matrix
encoding circuitry for channels 7 and 8. Rotating the Width Control regulates the apparent width of the Mid-Side stereo signal.
NOTE: When using channels 7 and 8 in M-S Matrix mode, connect your Mid (Cardioid) microphone to channel 7 and your Side
(Figure-8) mic to channel 8.
19. Channel 8 Phase Reverse – Pressing and locking this switch to the IN position reverses the phase of the output signal on this
channel. This is useful when using two adjacent channels to mic a stereo source.
20. Sample Rate Selector – This three-position selector switch determines the sample rate of Octane's digital outputs. Selecting 44.1k or
48k sets Octane's digital output to the selected sample rate, using Octane's internal clock. Selecting Ext will lock Octane's digital output
to the sample rate being fed to Octane's rear panel word clock input from an external digital source.
21. Power Switch and LED – Pressing and locking this switch to the IN position powers Octane on. The adjacent Power LED lights to
indicate powered-on status. Pressing the switch again will release it and power Octane off.
NOTE: Always use caution when powering on a preamp or other audio device, as they can produce audio peaks that can
damage speakers. Turn your monitors down fully, or keep them powered off, until the unit is powered on.
