Switch the "Power" selector to the "On" position (see line drawing). Audio Connection Plug in the audio input(s) to "Line In Channel 1 and/or 2" via 3 pin XLR for mic level input or ¼" plug for line level (see above line drawing). Using the "CH selector" (see line drawing), select Channel 1 (for single channel audio at 2. 3 MHz); Channel 2 (for single channel audio at 2. 8 MHz); or, Stereo (for 2. 3 and 2. 8 MHz) operation. To feed recording equipment or house PA system, use the "Line Out" connections (see line drawing) via ¼" plug(s). Audio Adjustments The SP230 comes equipped with internal Automatic Gain Control (AGC) circuitry which automatically adjusts the audio levels, therefore, set the line level controls (see line drawing) to the maximum (clockwise) position. When using a combination of mic level and line level inputs, mixing the audio input signals can be accomplished using the "Line Level 1 and/or 2" control knobs to achieve the desired output. Master / Slave Options The SP230 can be used as a Master unit, when used alone; or, as a Slave emitter when used with a separate modulator (e. g. , SI1015 rack mount modulator). [. . . ] If using the SP230 with an SZI1029 or SZI1015 emitter, position each unit in the corners of the front of the room diagonally facing the center of the rear of the room. [. . . ]
