CLIO POWER AMPLIFIER + SWITCHING BOX QCBOX MODEL 4 VIA MANFREDI 12-50136FIRENZE-ITALY TEL : +39-0556599036 - FAX : +39-0556503772 E-MAIL: WEB: , AUDIOMATICA ! 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. !
