Studio Technologies Expands Dante Beltpack Range

Studio Technologies just introduced the new Model 371 Intercom Beltpack. The compact, lightweight unit combines the features offered by broadcast-style, two-channel party-line (PL) intercom user devices with a single-channel listen output and a four-pin male XLR headset interface connector.

The flexibility of Dante and its inherent support of standard IP networks mean that multiple Model 371 units can be used in PL intercom applications with help from audio matrix units, such as the new Studio Technologies Model 5422 Dante Intercom Audio Engines. Model 371 units can also be directly interfaced with ports on compatible matrix intercom systems.

The Model 371 has switches that allow control of the microphone pre-amplifier gain and talk button operation and each button can be individually configured for push to talk or push to talk/tap to latch operation. An integrated call function allows Model 371 users to send and receive channel-specific visual alert signals. Additional features include integrated sidetone, remote microphone off and application firmware updating via a USB port. Model 371 units interface with twisted-pair Ethernet local-area-networks using standard RJ45 patch cables. This LAN connection provides both Power-over-Ethernet (PoE) and bidirectional digital audio signals.

Using a low-noise, wide dynamic-range microphone pre-amplifier and VCA-based dynamics controller (compressor) input, audio quality is preserved and the chance of signal overload is minimized. The resulting signal is routed to an analog-to-digital conversion (ADC) section that supports a sampling rate of 48 kHz and a bit depth of 24. The now-digital audio signal routes through a processor and onto a Dante interface section where it is packaged for transport over Ethernet. Similar care is taken with the two audio signals that arrive via the Dante interface. The resulting audio quality of the Model 371’s two independent talk and listen channels is excellent, with low distortion, low noise and high headroom.
