Studio Technologies introduced the Model 48D Dante Bridge for sending and receiving audio signals between two independent local area networks (LANs). Users can interconnect up to four Dante audio channels in each direction with isolation and preservation of network security. The Model 48D is compliant with Dante Domain Manager (DDM) and supports AES67 digital audio signals. Internal circuitry provides sample rate, timing and bit-depth correction to maintain audio signal integrity.

The Model 48D provides four Dante input (receiver) and four Dante output (transmitter) channels that support audio signals with sample rates of 44.1, 48, 88.2 or 96 kHz and bit depths of up to 24. Four audio channels in each direction can pass between the Model 48D’s two independent local area network interfaces when used with sample rates of 44.1 or 48 kHz. Two channels are supported when the sample rate is 88.2 or 96 kHz. Sophisticated sample-rate-conversion (SRC) integrated circuits ensure high-quality interchange of digital audio information.

The Model 48D is housed in a lightweight half-rack enclosure with its operating power obtained from either a Power-over-Ethernet (PoE) network connection or an external source of 12 volts DC. Optional rack-mounting kits allow one or two units to be mounted in 1U of a standard 19-inch rack enclosure. Features can be easily configured using the Dante Controller software application. In addition, the Model 48D is equipped with front panel LED indicators, an LCD display and five push button switches to allow viewing and revising of selected operating parameters.
