| APPLICATION: The RU‑SX4A is the ideal choice in many installations where either local and/or remote audio source selection is desired. Input and output connections are made on the rear panel through full‑size, clearly identified barrier block terminals. Each RU‑SX4A may connect directly to RDL's® wall‑mount RCS4, RC4‑RU or RUC‑4 remote controls. In stereo applications, a second RU‑SX4A may be wired as a slave. A front‑panel push‑button selects the desired audio source. Each time the button is pushed, the RU‑SX4A advances to the next audio source. Remote push‑button terminals are available on the rear. The RU‑SX4A features four balanced line‑level inputs. Each input may be wired balanced or unbalanced. The inputs are all bridging, allowing connection from either high or low impedance sources. The audio output is line‑level low‑impedance balanced, and may be wired to drive either a balanced or unbalanced line. Individual multi‑turn level trimmers are provided on the front panel for each input. | 
| Typical Performance: | Inputs (4): | | Each 20 kΩ balanced or unbalanced via terminal block, line‑level | Headroom: | | > 18 dB (above +4 dBu) | Gain: | | Unity +/‑12 dB (adjustable for each input) | Frequency Response: | | 10 Hz to 50 kHz (+/‑ 0.25 dB) | THD+N: | | < 0.010% (20 Hz to 20 kHz) | Residual Noise: | | < ‑85 dB (referred to +4 dBu) with an input selected (–93 dB typical)
< ‑95 dB (referred to +4 dBu) with no input selected (–100 dB typical) | OFF Attenuation: | | > 85 dB | Crosstalk: | | < ‑85 dB (1 kHz); < ‑75 dB (using pink noise) | Indicators: | | Front‑panel LED indicating selected channel | Common Mode Rejection: | | > 55 dB (50 Hz to 120 Hz) | Output (1): | | Balanced @ 150 Ω to drive high or low impedance balanced or unbalanced line | Power Requirement: | | GROUND‑REFERENCED, 24 to 33 Vdc @ 75 mA |
