RXU-8A
Designed with flexibility in mind, the RXU-8A
can be used as a regular MT receiver, where
the extra electric channels can be used to
acquire a redundant recording on the same site
or to acquire an adjacent site.
Excellent choice for controlled source
acquisitions that require a large density of
electric channels. The RXU-8A can also work
for special applications where extra electric
inputs might be needed.
