| Software Used: | Windows98 SE. Midiman Delta-66 Driver Release: 4.05.1031 (10/21/99) Card used for data acquisition was a Card Deluxe. Analytical software: Spectra Lab 4.32.14. Test done using a P2-500 CPU in a Asus P2B-B system board. | |||
Notes
Each analog input and output on this card has 3 modes: "+4, "consumer", and "-10" In "+4" mode this card records a +4 dB analog signal signal 10 dB below digital Full Scale (FS). In other words a +14 analog signal is required to record at digital FS. The "+4" dB levels are referred to 1 milliwatt delivered to a 600 ohm load (0.778 volts RMS).
Discussion Of Results
The digital portion side of the card are "bit perfect". It is even capable of passing AC-3 signals without alterations.
