The D-SH1 is utilized in applications requiring earphones of any impedance to be driven from customer or expert audio sources. The DSH1 is ideally fit to applications as varied as language translation, museums, interview studios and music stores. The module mounts conveniently in a precut opening in a wood or metal enclosure or in numerous RDL mounting accessories. The D-SH1 is a dual channel earphone amplifier with balancedunbalanced left and best inputs. Each input accepts operating levels between 20 dBV and 20 dBu. 2 recessed slide changes situated on the side of the rear enclosure are set prior to mounting the module. One switch is attended to setting the input sensitivity. The mode switch chooses between stereo and mono operation. In the mono position, the left input is utilized to drive both output channels. When the module is utilized in a monaural system, just the left channel input must be wired. The front panel level control is a long life potentiometer controlling matched VCAs. Audio does not travel through this control, assuring years of sound totally free level change. The output amplifiers deliver more than 50 mW into either high or low impedance earphones through a durable, metal 6.3 mm basic earphone jack. Module operation is from a 24 Vdc ground referenced power supply. It can likewise operate from a 12 Vdc supply with a 6 dB decrease in headroom and a maximum output power of 10 mW. - Power Supply Included
