Applies to: All OctoPre units excluding Platinum OctoPre and Platinum OctoPre LE
All the OctoPre audio inputs use 'combi' connectors. These can accept male XLR connectors, TS (unbalanced) and TRS (balanced) jack connectors.
If an XLR cable is used, then the pre-amp will automatically set to microphone level. If a 1/4-inch jack cable is used, then the pre-amp will be at line level. For instrument signals, use a 1/4-inch jack cable connected to input 1 or 2, and press the Inst button to switch to high impedance instrument level.
