About Wohler HRS-1S

Experience the superior audio monitoring capabilities of the HRS-1S 2-Channel Self-Powered Half-Rack Analog Audio Monitor. This high-quality, durable, and professional-grade device from the reputable brand, Wohler, is designed to deliver full-fidelity audio monitoring of two analog channels in the most compact space possible, occupying only half the width of a 1 RU rack space.

This innovative audio monitor features two high-performance transducers, each powered by its own amplifier. One amplifier-driver combination is dedicated to handling midrange and high-frequency information, while the second focuses on summed low-frequency information below the 500 Hz crossover point. This unique design ensures optimally focused sound, making it an ideal choice for operators in ultra near-field environments (1 to 3 ft.), reducing overall ambient sound and minimizing adjacent bay crosstalk.

The HRS-1S Audio Monitor is equipped with extended high-frequency response to reveal potential issues with audio whine or hiss. It employs electronic rather than acoustic cancellation of bass frequencies, providing positive audible detection of out-of-phase (reversed polarity) audio feeds.

For added convenience, a headphone jack is provided on the front panel, which automatically mutes the speakers when in use. The device also incorporates output limiter circuits to protect the speakers from potential damage. Moreover, the HRS-1S boasts extensive magnetic shielding, allowing for placement immediately adjacent to video monitors without causing any color impurities.

Whether you're in broadcast, live sound, or post-production, the reliable HRS-1S 2-Channel Self-Powered Half-Rack Analog Audio Monitor is a space-efficient solution for clear and accurate audio monitoring.
