RTS introduces the DSPK-4 Digital Speaker Station

RTS introduces the DSPK-4 Digital Speaker Station – new member of the RTS Digital Partyline intercom product family
  • Versatility – Available in desktop, flush-mount and wall-mount versions, each with a variety of power options and headset connectors
  • Hybrid functionality – Operate DSPK-4 in partyline mode with OMS (OMNEO Main Station) or in portable keypanel mode with an RTS matrix (ODIN/ADAM) – one device covers it all
  • User friendly – Compact and ergonomic design with full-color icon-based menu navigation for quick setup and intuitive operation

Burnsville, MN, Apr 15, 2023 RTS is pleased to announce the global introduction of the DSPK-4 Digital Speaker Station – the latest addition to the brand’s breakthrough RTS Digital Partyline product family, which also includes the OMS (OMNEO Main Station) and DBP (Digital Beltpack).

The DSPK-4 is an IP-based wired speaker station providing next-level versatility and functionality, including four channels of talk/listen via microphone and speaker or headset – all with high-quality digital audio and the use of standard Ethernet for easy integration into existing IT infrastructure. It adapts the unique hybrid IP/digital/analog functionality, ergonomic design and intuitive UX of the best-selling DBP into a sleek new form factor that is available in compact desktop, flush-mount and wall-mount versions. Flexibility is further enhanced with 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 like 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.

This makes the DSPK-4 ideal for new users or current partyline users looking to grow from analog systems into the superior sound quality and flexible connectivity of digital/IP communications, in verticals such as broadcasting, theaters/live entertainment, houses of worship, educational facilities, industrial facilities, event production and AV rental. Because it offers both digital partyline and matrix keypanel modes, DSPK-4 also offers excellent ROI for customers with existing RTS matrix intercom equipment. For example, an industrial facility can expand its comms inventory cost-effectively with RTS Digital Partyline – all while continuing to leverage the scalability of its existing matrix equipment. And, in addition to increased fidelity and a lower noise floor in comparison to analog, the DSPK-4’s Dante™ digital audio quality permits natural conversation levels and dynamics, free from feedback and latency – all of which can also add value by ensuring communications run smoothly during day-to-day operations.

The DSPK-4’s compact-yet-robust construction makes it ready for the toughest working environments, with over-molded ergonomic volume knobs and rubber enclosure detailing to provide extra grip and durability. The control layout is designed for an effortless user experience – for both new and experienced partyline users. An intuitive icon-based menu navigation system is presented via a full-color TFT display with anti-reflective lens, making local configuration quick yet precise in any light conditions. TALK and LISTEN capability for up to four simultaneously active partylines (i.e., access to a pool of up to 16 partylines) is equally 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). Users can enjoy peace of mind when powering the DSPK-4 with local DC +24 V, as PoE+/PoE++ will provide a redundant power supply if an unexpected outage occurs. Additional users can be easily added to the system using PoE connectivity – a single OMS can connect up to four analog partylines and up to 40 digital devices.

The DSPK-4 will be available in spring 2023.

*OMNEO onboard

DSPK-4 integrates into the RTS OMNEO ecosystem, for seamless connectivity with other OMNEO-enabled devices. OMNEO is an architectural approach for connecting devices over IP to exchange information, including audio content and device control. It is built upon multiple technologies, including IP and open public standards, to support the technologies of today — such as Audinate’s Dante™, AES67, AES70 and SMPTE ST 2110 — while evolving to support those of tomorrow.

OMNEO architecture is based on two main components: (1) an IP media transport solution that offers low-latency, high-quality, fully-synchronized multi-channel audio exchange; and (2) a robust control protocol that provides reliable, secure and highly scalable system control and monitoring for professional applications of all sizes – from a local board room to an intercontinental communications system.

OMNEO is fully compatible with Audinate's Dante™, AES67 and SMPTE ST 2110-30 for media transport. In addition, OMNEO has been designed to support emerging and future standards as they come to the market. The control solution in OMNEO is AES70 and is part of the OCA (Open Control Architecture) Ecosystem. It includes many features for flexibility, reliability, scalability and compatibility for today and tomorrow. OMNEO features many additional elements to ensure a complete and superior solution for the applications and products in which it is used, such as flexible networking topologies, optional encryption, optimized network performance and more.
