For sale is ONE (1) used audio monitor in very compact form of half rack unit. Power supply is missing, not included. Good working condition with some minor scratches/scuffs, tested with a bench test ps. Because we have a quantity of these, appearances may vary, but condition is guaranteed to be better or equal to pictured sample. Serial numbers are unique to each unit sold and may be different from one depicted in the photos - we record all serial numbers of all items shipped.
The Wohler HRS-1S provides self-powered, full-fidelity audio monitoring of 2 analog channels in the smallest space possible (half-width 1 RU). This unit contains two high performance transducers driven by two power amplifiers: one amplifier/driver combination handles midrange and high frequency information, while the second handles summed low frequency information below the 500 Hz crossover point.
The unique design allows this unit to fit almost anywhere, and provides optimally focused sound for operators in an ultra near field (1 to 3 ft.) working environment. This provides for a higher SPL for the operator while reducing overall ambient sound and adjacent bay crosstalk.
Extended HF response reveals potential problems with audio whine or hiss. Electronic rather than acoustic cancellation of bass frequencies provides positive audible detection of out-of-phase (reversed polarity) audio feeds. A headphone jack is provided on the front panel, usage automatically mutes the speakers. Output limiter circuits are incorporated to protect the speakers, and extensive magnetic shielding allows placement immediately adjacent to video monitors with no color impurities.
