LT600-VC Versatile unit for matching telephone-type, 600 Ω line circuits with HI-Z circuits. It can also be used as 
a 600 Ω to 600 Ω isolation transformer. Recommended for coupling of telephone-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 Ω input may be matched to 600 Ω, 10K Ω and 25K 
Ω circuits. All components are mounted on a printed circuit board. Steel chassis includes mounting ears and "instamount" 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).
