The Radio Design DS-SH1 is a surface mounted, stereo / mono, headphone amplifier for audio installations of any kind. Museum exhibits, private audio monitoring installations, and listening stations are among some of the possible applications the DS-SH1 is suitable for. The module mounts conveniently in a precut opening in a wood or metal enclosure or in various RDL mounting accessories.

The dual-channel headphone amplifier features balanced/unbalanced left and right inputs that accept operating levels between -20 dBV and +20 dBu. Two recessed slide switches located on the side of the rear enclosure are set prior to mounting the module. One of the switches sets the input sensitivity, the other selects between stereo and mono operation. The front panel level control is a long-life potentiometer. Because audio does not pass through this control, it can provide years of noise-free level adjustment.

Because audio does not pass through the Radio Labs DS-SH1 control, it assures years of noise-free level adjustment. This, with the integral long-life VCA stereo level control (with balanced or unbalanced inputs) means you will have a durable and dependable amplifier.

It comes with built-in headphone adaptability. The output amplifiers deliver more than 50mW into either high or low impedance headphones through a 1/4" (6.3mm) standard headphone jack.

This unit adapts to studio or office. This Radio Design amplifier is designed with the convenience of APPFLEX Mounting allowing panel-mounted or wall mounted functionality.
