International orders*The Radio Design RU-SH1 is used in applications requiring headphones of any impedance to be driven from consumer or professional audio sources. This model is made for rack mounting.
The RU-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.
