Line Output

Both Channel A and Channel B have discreet direct outputs on female XLR connectors. The signal on this output is exactly equivalent to the signal from the corresponding input. The level of the output signal is not affected by the gain setting for that channel. Additionally, signal delivered on the RCA (phono) jacks is not present on the Channel B direct line level output.

The Post-Gain Line out female XLR connector is a mixed output of Channel A, Channel B and the RCA (phono) jacks. This mix is affected by gain knobs on both Channel A and Channel B and the MIC/LINE switch on Channel A, but the output level is still Line Level.

WARNING! Do not connect the POST-GAIN LINE OUTPUT of a K Series system to any INPUT of the SAME UNIT. This output is designed to send signal to OTHER K Series units or to other audio equipment. Failure to follow this warning may result in very

unpleasant sounds produced at extremely high output volumes.
