DA<br />

• Resolution DA: 24 Bit<br />

5.3 Transfer Modes: Resolution / Bits per Sample<br />

• 32 bit, 4 byte (stereo 8 byte)<br />

This format is compatible with 16-bit and 20-bit. Resolutions below 24-bit are handled by the<br />

audio application. The card works internally with 32-bit data, but audio data transfer is limited to<br />

24-bits.<br />

5.4 Power supply<br />

• The CardBus card does not provide power to the attached I/O-box. Therefore a hi-tech<br />

switching power supply is included<br />

• The PCI card operates as power supply for the attached I/O-box<br />

The <strong>Multiface</strong> draws a high startup current of more than 2.5 A during initialisation. Current at 12<br />

Volt operating voltage: unloaded 500 mA (6 Watts), loaded 760 mA (9 Watts). Supply voltage<br />

range DC 7 V – 38 V, AC 7 V – 27 V.<br />
