PRODUCT DESCRIPTION

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-01, MIC-02 or MIC-03 as well as any other standard balanced microphone to any of the FW-01 input.

CONNECT THE FW UNIT TO PC OR NOTEBOOK
To connect the FW-01 unit to your PC you need to do the following:
1) Locate an IEEE-1394 port on your PC. You may either use a standard 6-pin port (with or without power supply) or a standard 4-pin (small connector, without power supply) port.
2) If you use a 6-pin port use the supplied 6-pin-to-6-pin cable. If you use a 4-pin port please provide an IEEE 1394 6-pin-to-4-pin cable (often referred as i-Link).
3) If you use a 6-pin port verify that it is capable of power supply.
4) If you use a 6-pin port without power supply or a 4-pin port you must also provide a 12V external power supply.
