The LT600-VC is a versatile unit for matching telephone-type, 600 ohm line circuits with HI-Z circuits. It can also be used as a 600 ohm to 600 ohm isolation transformer. Recommended for coupling of tele-phone- type lines into amplified sound systems, background music and paging systems, recording equipment, or studio electronics. Built-in potentiometer provides optional adjustability for the 25K output level. The 600 ohm input may be matched to 600, 10K and 25K-ohm circuits. All components are mounted on a printed circuit board. Steel chassis includes mounting ears and "insta-mount" tape. Transformer is shielded to minimize induced hum. Unit includes a phono jack on the output side for convenient connection to amplifier or other equipment circuitry. Jack can be connected to various transformer taps via barrier strip jumper. (Factory-installed jumper connects jack to potentiometer output).
