POD16 is a unity gain two by one stereo audio fader/mixer. Connections to POD16 are on the rear panel via two rows of screw terminal blocks. POD16 offers 4 transition modes; manual, linear voltage cross fade, linear dB cross fade and linear dB V-fade. Transition times for all modes are set by a front panel trim control which is variable from 10mS - 2 seconds. Mode selection is made from front panel push buttons while input selection can be from the front panel or by external tally inputs available on rear panel terminal blocks. The front panel push buttons and the external tally inputs can override each other; the most recent event will be activated. POD16 can also be supplied with a RS422 serial control port. Consult factory for this option.
