Product Overview
The Atlas Sound HT327 is a high-quality 70.7V line matching transformer rated at 32 watts, designed for use with standard 8-ohm loudspeakers in 70V distributed audio systems. Built with audio-grade laminations and offering multiple primary tap settings, the HT327 delivers minimal insertion loss and wide frequency response for reliable voice and music distribution in commercial paging and background music installations. It is designed for external mounting on surfaces other than the speaker itself.
Product Description
The HT327 transformer is engineered for high-power 70.7V distributed audio systems where sound quality and minimal signal degradation are priorities. Constructed with audio-grade laminations, the transformer delivers consistent performance across a broad frequency range from 30Hz to 15kHz with a maximum insertion loss of only 0.6dB. Primary tap selections at 8, 16, and 32 watts give installers the flexibility to balance multiple speakers across a 70.7V amplifier circuit without recalculating system impedance. Secondary outputs at both 4 and 8 ohms accommodate a wide range of loudspeaker configurations. The HT327 is designed for surface mounting outside the speaker enclosure, making it an ideal transformer for field upgrades or new installations where a speaker does not include a built-in transformer. With a shipping weight of 3.5 lbs, the unit is compact enough for concealed mounting in rack spaces, above-ceiling installations, or wall cavities. The 60-month warranty reflects AtlasIED's commitment to long-term product reliability in demanding commercial environments such as schools, office buildings, retail spaces, and transportation facilities.
