1 - THE QCBOX MODEL 4 AMPLIFIER & SWITCH BOX

The QCBOX Model 4 amplifier and switch box is of invaluable help in everyday laboratory

use and when configuring an automatic or manual quality control setup.

The QCBOX Model 4 has an ultraslim design, increased power (50W@8Ohm) with

respect to its predecessors Model 1, 2 & 3 and wide range AC (90÷240V) power supply.

Its main feature is the possibility of internal switching, under software control, that

permits the measurement of the impedance and frequency response of the loudspeaker

(or D.U.T.) connected to its output sockets without changing the loudspeaker (or

D.U.T.) wiring; it is also possible to choose one among four inputs for the response

measurements; the internal switching is controlled via the parallel port of the PC.

A dedicated output, ISENSE, allows impedance measurements in constant voltage

mode as well voice coil current distortion analysis.

A dedicated input, PEDAL IN, permits an external foot pedal switch or TTL signal to be

connected and trigger QC operations.
