The front panel of the DB-RT2 features two pushbuttons with two associated LEDs. Upon initial power-up, the OFF mode is selected. Touching the other button de-selects OFF and immediately selects ON. An LED adjacent to each button shows which mode is selected. In a typical installation, the DB-RT2 may be used to turn an audio or video source on or off. To turn on an audio source, the DB-RT2 may be connected to an RDL ST-SSR1 or ST-RX2 Solid-State Audio Switch. For video switching, an RDL TX-MVX may be used. In each of the above examples, only one output terminal is needed for triggering, therefore a single shielded pair (3-conductor cable) is required for remote connection. For more complex switching networks, both outputs (ON and OFF) may be used. In an audio or video control installation, the DB-RT2 may be mounted adjacent to an RDL remote volume control, such as the RLC2, RLC3 or RLC10K. In installations where ULTRASTYLE™ wall controls are preferred, use the RUC-4 Universal Remote.
