Studio Technologies Model 48D Dante Bridge (Open Box)

About: Studio Technologies Model 48D Dante Bridge (Open Box)

The Model 48D Dante Bridge provides a simple yet high-performance means of interconnecting, or "bridging," Dante® audio signals associated with two independent local-area-networks. The unit allows up to four audio channels to pass in each direction. Internal circuitry provides timing and bit-depth correction to ensure that audio signal integrity is maintained.

Key Features

• Two independent Dante network connections
• "Bridges" up to four audio channels in each direction
• High-performance sample rate conversion
• Excellent audio quality
• DDM and AES67 support
• PoE and optional 12 Vdc powering
• Standard connectors, simple setup
• Table-top, portable, or optional rack-mount installation
