The Nixer RL64 is a 1U 19 inch rack mounted Dante monitoring and mixing unit, which allows two modes of operation a mixing mode which can mix up to 64 Dante channels at 48kHz (32 channels at 96kHz) plus microphone input (via headphone connector) and AES input to create a 67 into 2 mixer. Alternatively, it can be set into a simple Listen mode where touching a channel instantly routes to the LR output and cancels any previous selection.
