Description
The DB-RT2 is a compact wall-mounted remote control selector designed to provide simple ON or OFF selection for audio and video sources. The unit features two momentary pushbuttons and adjacent LEDs that indicate the current state. Upon power-up the unit defaults to OFF and the LEDs clearly show the selected mode.
Key features include discrete single-button selection for ON and OFF, open-collector outputs for triggering external devices, and LED status indication for immediate visual confirmation. The outputs are capable of driving 25 mA maximum and support simple 3-wire or 4-wire remote wiring. The front panel provides a professional aesthetic suitable for installed AV environments.
Technical details include two momentary pushbutton selectors and two green/red LEDs to indicate ON and OFF status. Connections are made via a detachable terminal block providing power input and separate open-collector outputs for ON and OFF. The product requires a ground-referenced 24 Vdc supply drawing approximately 30 mA.
Connectivity is straightforward: a single shielded pair is sufficient for basic triggering while both output terminals may be used for more complex switching networks. The DB-RT2 interoperates with RDL ST-SSR1, ST-RX2, TX-MVX and other control devices that accept open-collector trigger signals. Mounting fits standard US electrical boxes and compatible RDL WB- or SMB-series boxes.
Typical applications include remote selection of audio sources, video source control, and simple on/off control of AV devices in installed systems. The selector is often mounted adjacent to RDL remote volume controls to provide discrete source enabling alongside level control. LED indication and single-button operation reduce user confusion in shared AV spaces.
Installation is straightforward and intended for professional integrators and installers. The detachable terminal block simplifies wiring and the device’s 24 Vdc ground-referenced power requirement aligns with common control systems. The DB-RT2 provides a durable faceplate appearance and straightforward function for reliable everyday operation.
