(2) ENCODER KNOB controls volume when the default DSP menu is active. Press the encoder knob to access DSP sub-menus and parameters. When the sub-menus are active, rotate the knob to change parameters. (3) WIRELESS SYSTEM LEDs indicate wireless microphone signal input. (4) WIRELESS SYSTEM USB input accepts only the BEHRINGER wireless microphone receiver. NOTE: The wireless USB input works in parallel with the INPUT A/B analog inputs, which means the wireless microphone signal can be heard at the same time as audio coming in through the INPUT A/B connections. We recommend you unplug the INPUT A/B connections in order to hear the wireless microphone signal alone. (5) INPUT A/B combo jacks accept input signals over XLR balanced, ¼" TRS balanced, or ¼" TS unbalanced connectors. (6) MIX OUTPUT jack sends a combined signal from all inputs (INPUT A/B jacks, wireless microphone, and Bluetooth) out over a balanced XLR connection. (7) POWER SOURCE jack accepts the included IEC cable. (8) POWER switch turns the unit off and on. Quick Start Guide 11
