RDL ST-SX4 Unbalanced Audio Switcher 4x1

Unbalanced Audio Switcher - 4x1 The ST-SX4 accepts up to four unbalanced audio sources. Any of these sources may be selected to feed the output, or all sources may be switched off. The output from the ST-SX4 is unbalanced. Control of the module is accomplished through a single input terminal. Connection of a specified resistance between the CTRL input and ground causes the desired input to be switched on. The necessary external resistors are supplied with the ST-SX4. The ST-SX4 may be remote controlled using the RC4-ST remote control.Features: Select 1 of 4 Unbalanced Audio Sources Audio Selection from Remote Location Remote Switching from Single Control Pair All Solid-State Audio Switching Slave Capability for Stereo Switching Specifications: AUDIO: Input and Output Level: -10 dBV Gain:Unity Headroom:23 dB THD+N:< 0.1% Typ. 0.05% Frequency Response:15 Hz to 40 kHz (+/- 0.5 dB) Input Impedance:100 kΩ, unbalanced Output Impedance:< 50 Ω, unbalanced Crosstalk:Below noise floor Off-Channel Attenuation:> 85 dB @ 1 kHz > 80 dB @ 10 kHz > 75 dB @ 20 kHz Residual Noise:< -70 dB (referred to -10 dBV) CONTROL Control Input Resistance:10 kΩ (pullup to +15 Vdc) Control Input:Single terminal to be connected to ground terminal to select desired channel.
