The Broadcast Industry Standard for Analogue Telephony

The HY-03S is the 19-inch rack-mount version of the classic HY-03 analogue hybrid. It maintains the same high-performance circuitry that established the HY-03 as a global industry standard for reliable, high-quality telephony in radio and TV broadcasting. Its rack-mount design ensures a professional appearance and secure installation within central control rooms and equipment racks.

Designed for Reliability and Longevity

Engineered for 24/7 reliability, the HY-03S features a switchable universal power supply and robust construction. It remains an excellent choice for facilities that continue to maintain analogue PSTN infrastructure and require a reliable, "set-and-forget" solution for managing external telephone contributors.

Important Note on Availability

Like the free-standing HY-03, the HY-03S is a legacy product and is no longer in active production. While these units may still be available through specialized secondary markets or remaining stock, they have been superseded by the DHY-04 digital series, which provides significantly higher performance and compatibility with modern digital/VoLTE infrastructures.
