Features

The LSC-B is a universal unit which in the field of audio logging performs the central function of audio
distribution and control.

When radio and telephone communications need to be logged over extended periods of time,
versatile custom solutions can be offered based on tape recorders of the REVOX series C.

When 4 or 8-channel machines type C274 and C278 are used, the date and time can also be recorded
because a clock chip is standard equipment in the C-series.

The interfaces of these machines are standardized and present no connection problems because
prefabricated cables can be used.

To make sure that the audio log is absolutely complete, the short (approx. 300 ms) start-up time from
the wear-free standby mode is compensated by a digital audio delay unit.

Gaps in the audio log resulting from equipment manipulations (tape change, rewind) can be
prevented by connecting a second tape recorder. This adds additional security to the logging system.

Up to 8 tape recorders of the REVOX C-series can be connected via the RS-232 audio distributor. Also
non-addressable units, for example a tuner, can be integrated by means of the four switch-controlled
RS terminals.

Like the delay circuit boards, also the input boards feature a 4-channel design. For telephone inputs
they are equipped with electrical isolation and on/off- hook detection. The radio inputs are balanced,
transformerless, and equipped with level detection.

With the fader start cabling, two tape recorders can be operated in flip-flop mode (mutual
concatenation). 1f the processor board option is used, the individual machines can be changed over
via the Rs interface.

Programing:

The INTEL 8052 AH processor is equipped with an 8 KB BASIC interpreter.

The programs can be burned directly' into the 16 KB EPROM where they are protected against power
failure. For automated sequences and logging as well as special audio circuits, the system can also
operate autonomously without permanent connection of a PC.

With the universal operating unit the LSC-8 can be adapted to the program to be executed. Three
momentary-action push buttons and4 self-holding push buttons with one LED each are available for
user programming.

Standard software modules are supplied which enable the user to program his own execution
sequences in BASIC.
