15:CD inputs - Connect the outputs of a CD or tape player to this set of dual phono jacks. Signal arriving here returns to stereo channel 3/4. If an optional TD30 cassette player is installed, note that its output also arrives at channels 3/4, in addition to line-level signal arriving at its 1/4" TRS line input (see #6 on the preceding page) and signal from a microphone connected to its mic input (see #7 on the preceding page).

16:AC input - Connect the supplied heavy-gauge 3-pin “IEC” power cable here.

17: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.

18:Voltage selector - Make sure this is set correctly for the country you are in before turning on the power to the EX30.

19:Gain switch - Sets the line-level TRS input of channel 3/4 (see #6 on the preceding page) to either +4 (professional) or -10 (consumer) level.

20:Power switch - Use this to turn power to the EX30 on or off. If an optional

RB 2030 rechargable battery pack is installed, it will charge when this switch is in the “Off” position.

Interconnecting the EX30

Using one EX30: In this example, microphones are connected to the XLR mic inputs of channels 1 and 2, and a stereo keyboard is connected to the stereo 1/4" TRS connector of channel 3/4 (using a Y-cord, with the tip carrying the left signal and the ring carrying the right signal). IMPORTANT NOTE: When using just one EX30, always be sure to set its Mono/Stereo switch to “Mono.”
