Kemper Profiler to Bose Portable PA

• XLR connection. This is a balanced connection and it is preferable
• 1/4 inch (6.35 mm) Tip-Sleeve (Ordinary guitar cable). Avoid using this connection when you have cable runs in excess of 20 feet (six meters).
  There is no advantage to using a 1/4 inch (6.35 mm) Tip-Ring-Sleeve cable because the 1/4 inch (6.35 mm) Profiler outputs are unbalanced.

Profiler Main Outputs

These are your main stereo outputs. Use these outputs to connect to a mixing desk in a recording studio, or to the front-of-house mixer in a live situation. These outputs deliver the entire Rig: amp, cabinet, and all effects. You have a choice of XLR (balanced) or quarter-inch TS-jacks (unbalanced). The XLR outputs are protected against 48V phantom power fed by a mixing desk. However, you should avoid feeding phantom power into the PROFILER if you want the best audio quality. Like all inputs and outputs, it offers a ground lift to prevent a loop hum.
