Two channels increase
your testing capabilities. Many diagnostic tests such as SISI, DLI, ABLB,
Carhart decay and Stenger
are built in. Special functions like channel swap, tracking and interlock
make operating the instrument easy. A built-in amplifier for your freefield speakers eliminates the need for an
external amplifier.
