PRODUCT DESCRIPTION
The QCBOX Model 4 is a non-conventional
unit designed to fulfill the needs of an electro-acoustical analyzer like
the CLIO system. It can be configured, under software control, to assist
frequency response or impedance measurements. In the first case it acts
like a 50W power amplifier to drive the speaker or network under test while
routing one-of-four inputs to the analyzer. The input can provide phantom
power supply for Audiomatica MIC-01 or MIC-02 microphones. In the second
case it presents the D.U.T.s load across the analyzers input.
A dedicated output, ISENSE, allows impedance measurements in constant voltage
mode as well voice coil current distortion analysis. A dedicated input permits
an external foot pedal switch (or TTL signal) to be connected and trigger
QC operations.
The QCBOX Model 4 finds use in laboratory or production lines setups.
19 RACK MOUNT ASSEMBLY
Using the Rack QC panel it is possible to assemble the QCBOX Model 4 together the SC-01 Signal Conditioner so that they can be mounted in a standard 19 rack frame.
