Studio Technologies Model 5330 Flex-Use Dante Audio Interface

Studio Technologies Model 5330 is a fully professional product that offers the audio quality, features, and reliability required by 24-hour commercial applications. Four inputs, two on the front panel and two on the back, allow simple interfacing with a variety of unbalanced and balanced line-level analog sources. The 2-channel (stereo) input on the front panel is optimized for use with portable electronics that provide “-10” unbalanced audio sources. Using a rotary control, users can adjust the sensitivity of the input circuitry to match the level of the source. Two additional inputs are provided on the back panel and meet the requirements of professional audio equipment

Four digital audio channels enter the Model 5330 via its Dante interface. These general-purpose audio channels are then converted from the digital domain to the analog domain. Four 3-pin male XLR connectors, located on the unit's back panel, provide balanced +4 dBu-nominal line-level analog outputs. An auxiliary output, also located on the back panel, provides a fifth “professional-quality” output.

The monitor section allows the user to select any audio input or output signal for visual and aural observation. Two 8-segment LEDs meters, calibrated in dBFS, allow precise monitoring of signal levels as they exist in the digital domain. A 2-channel (stereo) headphone output allows connection of headphones or ear buds that use either 3.5 mm or 1/4-inch jacks. A separate line-level analog monitor output allows connection to inputs on amplified speakers or power amplifiers.

An Ethernet connection is all that's required to make the Model 5330 part of a sophisticated networked audio system.
