INTRODUCTION Thank you for your purchase of the Rolls RA62c Stereo Headphone Amplifier. The ROLLS RA62c is a six-channel headphone/earphone amplifier for professional audio monitoring. A variety of input options are available including 1/4”, RCA, and balanced XLR. Since the MONO/STEREO switch is after the pan control, it will mix 2 MONO signals and their balance can be adjusted with the Pan control. With the addition of rear panel Direct Input connectors, each channel may mix a second stereo signal.
