The MS8A follows with all the features of the MS6A, and improves the series by increasing the number of switchable sources to eight, and adding an additonal passive fixed level stereo output. This path is perfect for metering or a tape feed. A mono switch allows you to check phase compatibility of a stereo source and the left input only provides mono on all ouputs. This model incorporates ¼" TRS connections for all inputs and outputs.
