Audiomatica QCBOX Model 5 Amplifier, Switch & Test Box

The QCBOX Model 5 is designed to extend the functionality of an electro-acoustical analyzer like the CLIO system. It is USB controlled, through dedicated software, to assist frequency response and impedance measurements or to perform DC measurements.   Software controllable switching application 50 watt power amplifier with current sensing and software controlled current limiter Enables large signal parameter measurement thanks to superimposing a DC voltage Four line/microphone inputs with selectable phantom power supply   Audiomatica CLIOQC Model 5 Amplifier, Switch & Test 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 use. The main feature is 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 a USB port of the PC. The inputs 3 and 4 can be also configured to measure DC voltages with range ±2.5V and ±5V respectively.   An internal software controlled voltage generator can superimpose a DC voltage (±20V) to the amplifiers output, allowing for loudspeaker large signal parameters measurement.   A dedicated output, ISENSE, allows impedance measurements in constant voltage mode as well voice coil current distortion analysis. The ISENSE DC current is measured in a range ±2.25A.   A dedicated input, PEDAL IN, permits an external foot pedal switch or TTL signal to be connected and trigger QC operations. A DB25 connector on the rear panel features 5 digital in- and 6 digital outputs for external hardware control .
