- Switching Without Hard Relay Contacts
- Fast Switching for Audio Muting
- Selection by Open‑Collector Logic
| 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 RC2‑ST, RT2 or RUC‑4 remote controls. | Typical Performance: | Switching Time: | | Fast / Soft | Time required for NORMAL input to turn off: | | 10 us / 5 ms | Time required for NORMAL input to turn on: | | 15 us / 70 ms | Time required for SELECT input to turn off: | | 15 us / 10 ms | Time required for SELECT input to turn on: | | 20 us / 35 ms | Control Signal: | | TRIG terminal must be externally
pulled to ground | Control Current: | | 0.5 mA | THD+N: | | < 0.05% | Frequency Response: | | 15 Hz to 20 kHz (+/‑ 0.5 dB, bridging load)
30 Hz to 20 kHz (+/‑ 0.5 dB, 600 Ω load) | Noise (below +4 dBu): | | < ‑80 dB (85 dB typical) | Headroom (above +4 dBu): | | > 18 dB | CMRR | | > 45 dB (100 Hz, either port) | ON Gain: | | Unity (600 Ω balanced input/output) | OFF Attenuation: | | > 80 dB (10 Hz to 20 kHz, either input) | Indicators (2): | | LED showing active input (left LED=NORMAL; right LED=SELECT) | Power Requirement: | | GROUND‑REFERENCED, 24 to 33 Vdc @ 40 mA |
