I am using a guitar rig as a pre-amp into an XLS 2000. I would like to generate more volume to get the most out of the XLS. Do I have to have a mixer or is there another way? The guitar set up is a TC Electronic Nova System (specs below) and a Boss Equalizer (which has a level control that provides some volume boost): Guitar processor specs: Max. Output Level (Balanced/Unbalanced): 20 dBu/14 dBu, R-load = 1200 Ohm 20 dBu / 14 dBu / 8 dBu / 2 dBu > 104 dB, 20 Hz to 20 kHz <-98 dB (0.0013 %) @ 1 kHz +0/-0.3 dB, 20 Hz to 20 kHz I am playing live shows with limited set-up times so a mixer doesn't seem like a practical option. Thanks in advance for any suggestions.
