About the Reference 1
The Audio Research Reference 1 is a high-end vacuum-tube line-stage preamplifier using eight specially selected 6922 dual-triode tubes in an all-triode, differentially balanced circuit. It provides eight inputs—Tape, Tuner, Phono, CD, Video, and three Aux inputs—with both balanced XLR and single-ended RCA connections. Two main outputs and a tape output are provided in both formats. The unit offers remote-controlled electronic input selection, volume, balance, record selection, and phase controls, with a regulated solid-state power supply. Its maximum output is approximately 7V RMS balanced (3.5V RMS single-ended), rather than 30V RMS. The chassis measures approximately 19 inches wide by 7 inches high by 15.5 inches deep, excluding the front handles.
