The Radio Design AF-SH1 is used in applications requiring headphones of any impedance to be driven from consumer or professional audio sources. The module mounts conveniently in a precut opening in a wood or metal enclosure or in various RDL mounting accessories.

The AF-SH1 is a dual-channel headphone amplifier with balanced/unbalanced left and right inputs accepting 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 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.

Long Life Controls
Because audio does not pass through the Radio Labs AFSH-1 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.
Drives High or Low Impedance Headsets
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.
Convenient Mounting
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.
