I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.

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 â+3 dBâ 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
installed, this meter shows how much battery power remains as it is being charged (Power switch off) or depleted (Power switch on). 6: Volume control - This knob sets the level of the EX20âs built-in power amplifiers.
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 âonâ position during normal operation. 9: AC output - A standard AC power outlet. 10: AC input - Connect the supplied heavy-gauge 3-pin âIECâ 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.
