Feature Set

The quality and flexibility of Modular/8 makes it a great A/D D/A solution for broadcasters, DVD mastering, recording studios and audio post-production houses.

• Rugged internal power supply. This unit accepts both 110 and 220 voltages for worldwide use.
• Fully tested for CE compliance for guaranteed safety and stability.
• All module audio connections are made using high quality balanced XLR type connectors.
• Clear and easy to use front panel controls.
• Extremely high quality A/D and D/A using the latest generation in converter technology.
• High common mode rejection Balanced Input circuitry on all Analog Input modules for optimum rejection of power line hum, RF interference, voltage drops and other externally generated noise commonly encountered with long audio cable runs.
• All Analog Balanced Output circuitry incorporates the advanced "Twin Servo Drive" output stage for maximum output signal balance ratio performance, even under adverse asymmetrical loads.
• DVD Ready. Support for high Sample Rates such as 96 kHz at 24-bit resolution.
• Fits into standard 2 unit 19" rack.
• Local control from the front panel (in stand-alone mode)
• Remote control from STUDI/O host software (coming soon).
• Selectable Monitoring of all 8 inputs and outputs.
• Very comprehensive choice of Sync Sources, including lock to Video Blackburst and AES/EBU .
• Very low jitter and calibrated internal clock.
• 8 channel 24 bit 96kHz directly to computer via STUDI/O and S/MUX.
