NT-INSTRUMENTS MINILYZER analog audio analyzer/audio meter

Minilyzer ML1 is the state-of-the-art analog audio meter that fits
into the palm of your hand.
It provides you with a comprehensive set of functions essential
for the analysis of professional audio systems.The powerful Minilyzer
continuously measures the audio signal and displays the desired
results with all complementary information on an illuminated hi-res
graphical LC-Display.
The Minilyzer and the MiniSPL form a comprehensive integrating
sound level meter.
MiniLINK, the USB interface for the Minilyzer allows documentation
and data acquisition of all ML1 functions in conjunction with the easy
to use MiniLINK PC application. MiniLINK supports online data logging
up to several days.

Cable Tester ACT-100

The Alphaton active remote cable tester can be used for testing either normal short
cables or long ones, especially mufticores, wkh connectors not being accessible at
one time. The tester is especially suded for fixed installations where cables can not
be tested with a standard type cable tester or Ohm meter. Either symmetric and
unsymmetric cables can be tested.
“Cold" solderings and junction resistances are displayed by color or luminosity changes
in three color LED Display. The imprinted fault table incorporates alt important fault
conditions, indeed not all possible ones due to their reiatively large number. In case the
display is in a state which cannot be found on the imprinted table, it can be looked up in
the user's manual. In any case, however, the cabie is in aquite unusable state and should
be repaired or replaced.The Alphaton cable tester has a SEND and a REMOTE section.
The REMOTE sectionconsistsof two recessed mounted XLR type male or female connector
and a stereo phone jack at the right hand side of the tester. Additionally, a separate REMOTE
plug is delivered togetherwith the active remote cable tester for testing long cables in fixed
installations.
