9 Input Connections Full-range models have one female XLR line-level input marked FULL RANGE LINE IN. Subwoofers have a second set of connectors, one for the left channel’ s audio and one for the right channel’ s audio. We recommend balanced connections be used .
10 Output Connections Full-range models have one XLR output connector marked FULL RANGE LINE OUT . The output connector is wired in parallel with the input enabling connection of multiple enclosures in a “daisy-chain” fashion. Subwoofer models have two sets of output connectors, one set for the left and one set for the right audio chan- nel.
11 GAIN Control The GAIN control is marked in dB of attenuation. There are 21 detents for repeatable adjustments. T urn the GAIN con- trol clockwise to increase gain and counter clockwise to decrease gain. The upper 14 steps are about 1 dB each a nd settings should normally be made within this range.
