Electro-Voice 15732 32W Speaker Transformer for 25/70.7V Line, 0.5dB Insertion Loss, 50H-15kHz Frequency Response, 8 Ohms Impedance

After meticulous design and engineering, the Electro-Voice 15732 32W Speaker Transformer emerges as an essential component for optimizing distributed sound systems, particularly when dealing with installations that require loudspeakers to be placed at considerable distances from the amplifier. This transformer is specifically crafted to enhance efficiency and minimize loss in high-impedance transmission lines, including 70.7V constant voltage lines, which are prevalent in commercial audio setups. The Electro-Voice 15732 excels in matching the impedance of loudspeakers to that of the transmission line, ensuring a seamless integration within the system. Its design facilitates the most efficient transfer of power from the line to the loudspeaker, which is crucial for maintaining sound quality over long distances.

The transformer's primary and secondary windings are electrically isolated, which not only contributes to a balanced line to the load but also reduces the likelihood of electrical interference, preserving the integrity of the audio signal. With a frequency response ranging from 50Hz to 15kHz, the transformer maintains low insertion loss and low distortion, while upholding high efficiency across the entire audible spectrum. This ensures that the full richness and clarity of the audio are delivered without compromise, regardless of volume levels. The 70.7V line matching transformer is equipped with four selectable power taps, providing versatility and adaptability to different power settings.

Additionally, selectable line loss correction taps are ingeniously integrated to counteract line resistance, which can lead to significant cost savings by allowing the use of lower gauge wires without sacrificing performance. For ease of installation and maintenance, the transformer features primary taps clearly identified in watts for straightforward amplifier connections. These taps are accompanied by color-coded lead wires, eliminating any guesswork during setup. The 8-ohm secondary taps are designed with 0.25 -inch blade type quick-connect wire terminals, offering the convenience of wrap-and-solder connections or crimp type quick-connect terminals, thus catering to various installation preferences and requirements.

In summary, the Electro-Voice 15732 32W Speaker Transformer is an indispensable tool for audio professionals seeking to create efficient, high-quality distributed sound systems. Its meticulous construction and thoughtful features ensure that it stands as a reliable and high-performing solution for a wide array of audio applications.
