Depending on the hardware options that have been purchased, the CLIO system

consists of the following components:

– The FW-01 firewire audio interface

– TheMIC-02 microphones

– The QCBox Model 5 power amplifier, switching and testing box

The FW-01 Firewire Audio Interface sets new hardware precision standards for the CLIO System. The FW-01 unit has been designed to be a complete two channels professional A/D D/A audio front-end for your PC; it is connected to the computer by an IEEE-1394 link giving you maximum performances; it can be powered by the same link giving you maximum portability. The FW-01 performances (24 bit @ 192 kHz) represent state-of-the-art measurement capabilities for any audio device or

acoustical test. The FW-01 is equipped with an instrument grade balanced input and output analog circuitry with an exceptionally wide range of output attenuation and input gain that allows an easy interface to the outer world; the input and output loopback capability with the internal ultra stable voltage reference permit a simple and precise calibration of the whole instrument. A switchable phantom power supply lets you directly connect an Audiomatica ,MIC-02 as well
