RTS has announced the introduction of the DSPK-4 Digital speaker station, the latest member of its Digital Partyline product family that provides four channels of talk/listen via microphone and speaker or headset digital audio and the use of standard Ethernet for integration into existing IT infrastructure.
The IP-based wired speaker station adapts the unique hybrid IP/digital/analog functionality, ergonomic design and UX of the company’s DBP into a new form factor that is available in compact desktop, flush-mount and wall-mount versions. Also onboard are Bluetooth headset connectivity and PoE (Power over Ethernet) connectivity.
As with the DBP, the DSPK-4’s IP technology allows for hybrid use, supporting both digital partyline and matrix keypanel modes. For use as a digital partyline device, the DSPK-4 connects to an OMS; this also allows the integration of analog/two-wire devices within the digital/IP system, helping to extend ROI on existing analog equipment. For use as a matrix keypanel, including functionality such point-to-point communication, the DSPK-4 can be connected to any RTS digital/IP matrix product using OMNEO* IP technology, including OMI cards in ADAM/ADAM-M frames or OMNEO ports on ODIN frames. The DSPK-4 automatically selects the correct mode of operation (digital partyline/OMS or keypanel/matrix) when connected and switched on.
Because it offers both digital partyline and matrix keypanel modes, the DSPK-4 is also suited for customers with existing RTS matrix intercom equipment. For example, an industrial facility can expand its comms inventory with RTS Digital Partyline while continuing to leverage the scalability of its existing matrix equipment. In addition to increased fidelity and a lower noise floor in comparison to analog, the DSPK-4’s Dante digital audio quality is designed to permit natural conversation levels and dynamics that are free from feedback and latency.
The unit offers over-molded ergonomic volume knobs and rubber enclosure detailing to provide extra grip and durability. The control layout is designed for an easier user experience for both new and experienced partyline users. An icon-based menu navigation system is presented via a full-color TFT display with anti-reflective lens. TALK and LISTEN capability for up to four simultaneously active partylines (i.e., access to a pool of up to 16 partylines) is designed to be simple to control via four large backlit channel buttons.
A choice of three different XLR headset connector options are available for flush-mount models: 4-pin female, 4-pin male or 5-pin female. Desktop and wall-mount models are each equipped with all three connector types. Bluetooth headset connectivity via USB dongle is supported on all models. The desktop version comes equipped with an external AC/DC power supply unit (PSU); the PSU can be ordered separately for the flush-mount and wall-mount versions.
Users have the choice of powering their DSPK-4 via the PSU, local DC +24 V, or PoE+/PoE++ (Power over Ethernet). When powering the unit with local DC +24 V, PoE+/PoE++ will provide a redundant power supply if an unexpected outage occurs. Additional users can be added to the system using PoE connectivity – a single OMS can connect up to four analog partylines and up to 40 digital devices.
The new DSPK-4 will be available in spring 2023.
