Expedition EX20
Guided Tour
1: Input connector - Use this balanced female XLR connector to route line-level signal into the EX20. 2: Output VU meter - This three-segment bar meter shows the EX20 output level. For optimum signal-to-noise ratio, set the Volume control (see #6 below) so that program material is usually at or around 0 VU, with occasional but not steady excursions to the red �+3 dB� segment. 3: Power switch - Use this to turn power to the EX20 on or off. 4: Voltage selector - Make sure this is set correctly for the country you are in before turning on the power to the EX20. 5: Battery VU meter - If an optional RB 2030 rechargable battery pack is

7: Output connector- This balanced male XLR connector carries line-level output signal from the EX20. It is used to send signal to a second EX20 being daisy-chained (see interconnection diagram on the following page) or to an optional EX500 subwoofer. 8: Limiter switch - Use this switch to turn the built-in limiter circuitry on or off. In order to maximize speaker protection, we recommend that this switch be left in the �on� position during normal operation. 9: AC output - A standard AC power outlet. 10: AC input - Connect the supplied heavy-gauge 3-pin �IEC� power cable here.
Interconnecting the EX20
Using one EX20: A single mono signal (bus or aux send) is routed from a mixer to the EX20 XLR input.
