* Bus interface: PCI Bus master with 96 channel DMA interface insures
low system overhead for audio data transfers.
* Compatibility: Windows 95 / 98 / NT 4.0, Plug'n'Play-compatible.
* Audio converters:
- 18-bit ADC and DAC.
- Hardware-based sample rate converters for high-quality digital mixing.
* Signal-to-Noise: > 97 dB (A-weighted).
* THD: > 90 dB (0.0032%) (A-weighted).
* Stereo crosstalk: 1 KHz (-83 dB) 100 Hz (-97 dB)
* Frequency Response: 10 Hz - 20.5 KHz (+/-1 dB).
* Sampling Rates: up to 48 KHz.
* Games compatibility: compatible with all standard Windows games and most
DOS games (in Real Mode DOS). DOS game compatibility not available in NT.
* Digital audio processor
- Hardware full-duplex for simultaneous record/playback at full
bandwidth with independent record/playback rate.
- Auto-muting after periods of digital silence.
- 16 hardware digital mixers for processing PCI audio streams.
* Sample rate converters: hardware-based sample rate converters for
processing digital audio streams of different sample rates without
imposing any CPU processing load.
* Aureal 3D 2.0 interactive sound: hardware-based A3D positional audio
wave-tracing engine with wall reflections and occlusions (64 sources).
* Audio inputs/outputs:
- mono microphone input
- stereo line input
- stereo line output
- stereo aux input on internal header
- CD input on internal header
- modem audio in/out on internal header
* Wavetable synthesizer
- 64-voice hardware + 256-voice hardware-accelerated software
advanced wavetable synthesis
- 5 MB instrument samples stored in PC system RAM using DynamicVoice
Exchange(TM) caching, to minimize RAM requirements to only the
instruments being used.
- Reverberation and chorus on MIDI wavetable instruments.
- DLS-compatible for user-configurable instruments.
* Synthesizer Daughter Board
- 64-voice advanced wavetable synthesis with Roland GS-compliant
instruments.
- Channelized digital effects include reverb and chorus.
* MIDI interface: hardware-based MPU-401 MIDI UART-compatible interface
through joystick connector.
* Joystick interface: as well as providing standard analog/digital
joystick support, the digital joystick further accelerates game play
by performing remote polling of the joystick position without CPU
intervention.
* S/PDIF: Allows In/Out with RCA and optical connectors for recording
and playback of pure digital audio (requires an available space for
the bracket).
* MIDI interface cable: connects to joystick port to control external
MIDI devices via the MIDI port.
