    Description

    The ST-SSR1 was designed for absolute silent switching of audio signals. It supports two balanced line-level inputs and one balanced output. Each can be used unbalanced as well. The ST-SSR1 is perfect for switching between two input signals or as a silent On/Off switch for a single channel. Performance is in keeping with the technical standards for which RDL® has become known. The user can program the module for either fast or soft switching.

    The SELECT input feeds the OUTPUT when the TRIG terminal is grounded, otherwise the OUTPUT is fed by the NORMAL input.

    The control current required at the TRIG terminal is so minimal (< 0.5 mA) that the ST-SSR1 can be controlled from nearly any source from switches to logic circuits.

    The ST-SSR1 may be controlled using the RDL D-RC2ST or the D-RT2 remote controls.
