Splitter Interface
This splitter interface (Cat. No. 939) can be used if access to more than one of
the Auxiliary Receptacle functions is required simultaneously. Connecting the
interface to the 6-pin connector on the sampler provides three additional
connectors for use. Two or more interfaces may be connected in series to
allow for as many connections as desired.
