Lightweight and compact-fits next to audio equipment. Baluns work with full-range, hi-fidelity audio frequency systems. Extend the distance between input and output devices up to 3250 feet (1 km). Use inexpensive UTP cable instead of bulky coax to link an analog audio source to an integrated audio-video receiver or audio Hi-Fi system. These tiny baluns are ideal for multimedia configurations-use them in boardrooms, classrooms, auditoriums, home installations, and intercom systems. Connect DVD players, satellite receivers, MPEG players, laptops, hi-fidelity stereo audio amplifiers, audio switchers, AV monitors, and other Hi-Fi audio equipment to a Hi-Fi audio output with a pair of Hi-Fi Stereo Audio Baluns. The baluns operate in a point-to-point configuration at a distance of up to 3250 feet (1 km). They're compatible with other BLACK BOX baluns, such as the Audio Balun, Analog (IC460A) and the CATV Balun (IC448A-R2).
