2.4 THE QCBOX MODEL 5 POWER AMPLIFIER, SWITCHING AND
TESTING BOX
The QCBOX Model 5 power amplifier, switching and testing box is of invaluable help
when configuring an automatic or manual quality control setup, or even in everyday
laboratory use.
It can be configured, under software control via USB, to assist frequency
response and impedance measurements or to perform DC measurements.
Between its features is the possibility of internal switching that permits the
measurement of the impedance and frequency response of the loudspeaker
connected to its output sockets without changing the wiring to the speaker; it
is also possible to route one of four inputs for the response measurements; these
input have powering for a microphone (0÷24V variable).
An internal ADC measures the DC current into the voice coil; an over current limiter
is available to a predefined threshold. Thanks to an internal software controlled
voltage generator the speaker can be driven with a superimposed DC voltage
(±20V max), allowing for measurements of large signal T&S parameters. Two ADC
converters with a ±2.5V and ±5V are available at inputs 3 and 4 to measure the
displacement with a laser sensor or any other DC signal.
A dedicated output, ISENSE, allows impedance measurements in constant voltage
mode as well as voice coil current distortion analysis.
A 5 bit in - 6 bit out digital port is available to interface the QCBOX with external
hardware or line automation. An ulterior dedicated input permits an external foot
pedal switch to be connected and trigger QC operations.
