Crystal-MM-HP
Full-Duplex SoundBlaster Pro Compatible Stereo Audio PC/104 Module
 |
Description |
The new Crystal-MM-HP board is an upgraded PC/104 16-bit stereo audio module that features full-duplex performance, plug and play features, and significantly increased output power. It is fully compatible with the SoundBlaster Pro(tm) and Windows Sound System(tm) standards.
Loaded with Features
Full-duplex capability enables the board to perform simultaneous recording and playback on separate channels. Sample rates of up to 44.1kHz are supported for both record and playback. An extensive selection of audio inputs and outputs on multiple I/O connectors make Crystal-MM-HP easily adaptable to any application's configuration. Both pin headers and stereo mini-jacks are provided to enable easy connections to custom wiring as well as industry-standard connectors.
Crystal-MM-HP includes a 6-channel mixer with stereo inputs for line, CD, auxiliary, and MIDI, and mono input for microphone. Outputs include speaker, line, and MIDI. An optional mono I/O channel can be provided with a semi-custom configuration.
Plug and play configuration provides 4 DMA and 6 interrupt selections for increased flexibility and ease of installation. Additional features include a PC-compatible dual game port and connections for pushbutton volume and mute controls so that volume can be controlled both in software and through front-panel controls. Software drivers for DOS, Windows 3.1, Windows 95, and Windows NT are included.

I/O Headers |
A large variety of I/O headers is included on the board. Many audio signals are present on more than one header for increased flexibility in I/O connections. The two stereo mini-jacks are jumper-configurable for input and output source. The speaker outputs are available on a mini-jack, a dedicated pin header with external volume control, and a combination I/O main header. Note that only one speaker connection should be used at a time to prevent overloading the audio amplifier circuit.
