TEAC RD-125T Dual Speed DAT Data Recorder
Data recorded on the TEAC RD-125T data
recorder can be reproduced on any other RD series model, as long as the
number of recorded channels equals the number of reproduction channels.
For instance, data recorded using the RD-130TE in 8-channel mode can be
reproduced on an RD-130TE, RD-135T, RD-145T, RD-180T, RD-200T in 8-channel
mode. A GP-113 interface allows the data recorders' functions to be
controlled from a host computer. This feature also permits easy
configuration of automatic measuring systems.
Use of the ID number search system permits
high speed search at up to 200 times the record/reproduce speed in both
forward and reverse directions for speedy search of data header. End
search function rapidly locates the end of the last recording so that
further recordings can be made speedily. With an independent memo channel
and the front panel's built-in microphone, continuous hands-free recording
of the surrounding environment is possible during data recording.
Simultaneously recorded background sounds can be extremely useful when
analyzing recorded measurement data.
Memo announce and data signal can be
reproduced by the built-in speaker for any desired single channel;
extremely useful for aural evaluation of recorded data. BNC terminals and
operation switches are all provided on the front panel for centralized
control and easy access. This enables greater on-site work efficiency and
makes it easy to check multiple cable connections at a glance.
