Description

The VIA Vinyl Envy24 is a professional versatile PCI multi-channel I/O controller designed with the needs of the audio connoisseur in mind. With 8 input and output channels for analog and digital connections, the VIA Envy24 can meet the most demanding playback and recording requirements. Integrating a high resolution digital mixer the VIA Envy24 enables up to 20 channels of mixing power. This feature is aimed specifically for monitoring final outputs, and making master copies for budget conscious studios.

For easy integration by system designers, the VIA Envy24 can be combined with professional grade I²S converters, S/PDIF transmitters and receivers, and AC-link codecs. The VIA Envy24 includes SoundBlaster Pro hardware compatibility that is ensured under DOS for DDMA (Distributed DMA) and non-DDMA systems. The Envy24 also includes a Microsoft Win9x architecture based DirectSound accelerator that interfaces to AC'97 devices.

Additional connections include two independent MIDI UARTs enabling connections to multiple external MIDI devices that can be dedicated for different purposes. An 8-port GPIO connector provides an easy port for connection to additional connector cards, and a conventional standard joystick port is also provided.

The applications for the VIA Envy24 include professional high-end PCI audio, computer based telephony, discrete multi-channel audio and general purpose multi-channel I/O. More technical applications include PC-based multi-track audio, PC-based data acquisition, PC-based waveform generation, PC-based instrumentation, and PC-based control and automation.
