General Information
Manufacturer	RDL
Manufacturer Part Number	D-SH1M
Product Name	Stereo Headphone Amplifier
UPC Code	813721015006
Overview
The D-SH1M is used in applications requiring headphones of any impedance to be driven from consumer or professional audio sources. It is ideally suited to applications as diverse as language translation, museums, interview studios and music stores The -SH1 is a dual channel headphone amplifier with balanced and unbalanced left and right inputs. Each input accepts 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 switch is provided for setting the input sensitivity The mode switch selects between stereo and mono operation. In the mono position, the left input is used to drive both output channels When the module is used in a monaural system, only the left channel input must be wired. The front panel level control is a long life potentiometer controlling matched VCAs Audio does not pass through this control, assuring years of noise free level adjustment. The output amplifiers deliver more than 50 mW into either high or low impedance headphones Module operation is from a 24 Vdc ground referenced power supply
