DIGIGRAM PCX9 PCI AES/EBU BROADCAST AUDIO SOUND CARD 18-Bit Stereo PCI Audio Interface with Stereo Analog & AES/EBU Digital I/O specifications: - Two channel audio signal processing board for PC/AT built on the Motorola 56000 DSP family - Recording, processing and playback of professional-quality sound - Downloadable software driver allowing access to various types of processing - Analog audio input/outputs - AES/EBU SMPTE (LTC) time-code input Audio specifications - Two mono channel or one stereo analog inputs/outputs (18-bit AD/DA) conversion - Programmable sampling frequency: 48, 44.1, 32, 24, 22.05, 16, 11.025, 8 kHz, external frequency - Frequency response at 48 kHz (record + play): 20 Hz - 20 kHz, ±0,25 dB - Signal/noise ratio (record + play): > 88 dB - Distortion + noise at 1 kHz (record + play): < -84 dB (0.006%) - Balanced line inputs: impedance >18 kOhms or 600 Ohms by switch - Balanced line outputs and headphone output (600 Ohms) - Programmable input and output levels: maximum + 22 dBu - Analog internal CD-ROM input: maximum + 6 dBu Ressource Requirements - np driver 4.10 or higher Minimum Hardware Requirements - one level sensitive IRQ. - 64 bytes of I/O address - one PCI slot. Processing functions - Simultaneous real-time MPEG Audio compression / decompression (two channels), professional audio quality, reducing disk storage requirements in a programmable ratio of 1:4 to 1:24. At 128 kbps (1:6 compression at 48 kHz),1 minute of mono sound (or 30 seconds of stereo sound) takes up only 960 Kbytes. - Simultaneous record/playback in PCM mode (no compression) - Real-time mixing of several PCM or MPEG Audio files (up to 8 MPEG Audio Layer II stereo tracks at 256 kbps or up to 16 MPEG Audio Layer II mono tracks at 128 kbps) - A large choice of software functions, such as time-stretching, pitch-shifting, format and frequency conversion. Physical format and connections - PC/PCI bus board, one PCI slot, half-length format (180 mm x 99 mm) - Connections: - one 15-pin SUB-D connector for analog inputs/outputs - one 15-pin HD SUB-D connector for SMPTE input and AES/EBU digital inputs/outputs (optional) - one connector for internal analog CD-ROM input - one connector for inter-board synchronization. - 1 headphone jack (stereo jack 3.5 mm) Power Consumption +12V: 0.15 A, -12V: 0.1 A, +5 V: 0.75 A Operating Temperature Range 0°C to 70°C.
