Pin conventions
To unbalance the outputs of the Sumo the
-ve Pin should be connected to its
adjacent 0v pin at Sumo’s output.
Similarly, inputs from unbalanced sources
should be connected via twin screened
cables with the –ve pin connection tied to
the screen at the unbalanced source.
Inputs and outputs are implemented using
advanced electronically balanced
topologies and are fitted with extensive
RFI rejection networks.
Digital Interfaces
The optional digital card gives Sumo the
ability to output at six sample frequencies
up to and including 192kHz.
The card provides for both of the most
common stereo digital transmissions
standards:
AES/EBU on XLR, and S/PDIF on
RCA (that’s a phono plug to you and I).
Output on both connectors, for all sample
rates is fixed at 24bit.
A word clock input is also provided for
situations where Sumo is not the clock
master. This is connected via BNC.
