The RDL ST-SH2 is a miniature wall- and surface-mount stereo headphone amplifier. The unit is used for installation applications requiring headphones of any impedance to be driven from consumer or professional audio sources.
For fixed-level installations not requiring user volume control, the ST-SH2 is wired directly to the audio source and a headphone jack. The Left and Right level adjust terminals may be wired to the respective wipers of a stereo 10-kilohm potentiometer to provide volume adjustment.
The ST-SH2 offers exceptional low-noise operation, low distortion, audio clarity and near-zero crosstalk performance, suiting a wide variety of installed-audio system applications.
Wall mount stereo in-line headphone amplifier with provision for external stereo level control potentiometer
Ultralow-noise, high 115 dB dynamic range
Bridges a line input and provides remote headphone feed to multiple users not requiring individual level control
Accepts balanced and unbalanced inputs
Supports headphone impedances from 8 ohms to 5 kilohms
