Whatever the reason, we're happy to see the S/PDIF port included in the Quadzilla package, as it allows for a truer preservation of the original signal's sound when recording wave files to a Minidisc player, or other recording device.

The Quadzilla is loaded with the features that are virtually required to be able to seriously compete in the current high-end of the PC audio card market:

• Bus Interface: PCI Bus master with 96 channel DMA interface
• Compatibility: Windows 95/98/NT4.0 (95 Plug & Play compatible).
• Audio Converters: 18-bit ADC and DAC with 97dB Signal-to-Noise Ratio. Hardware-based sample rate converters for high quality digital mixing.
• Signal-to-Noise Ratio: 97dB (A-weighted).
• THD: Better than 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).
• 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.
• Sample Rate Converters: hardware-based sample rate converters for processing digital audio streams of different sample rates without imposing any CPU processing load.
• A3D 2.0 Interactive Sound: Hardware based A3D positional audio Wavetracing® engine with wall reflections and occlusions (96 DirectSound streams).
• Audio Inputs/Outputs: Microphone input, stereo line input, 2 stereo line output, stereo digital audio S/PDIF output, stereo aux input on internal header, CD input on internal header, modem audio in/out on internal header.
• Wavetable Synthesizer: 320-voice advanced wavetable synthesis (64 hardware + 256 accelerated software) with 5 MB instrument samples stored in PC system RAM using DynamicVoice Exchange™ caching to minimize RAM requirements to only the instruments being used. Reverberation and chorus on MIDI wavetable instruments. DLS compatible for user configurable instruments. (Wavetable performance dependent on system resources).
• 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.
• Speaker/S/PDIF Outputs: Requires an available space for the bracket.
