    • JENSEN JT-DB-E Direct Box Transformer

      JENSEN JT-DB-E Direct Box Transformer

      When loaded by the 1 kS input impedance typical of mic preamplifiers, this transformer has a 140 kS input impedance, making it ideal for high impedance sources. It can be used with or without an active buffer as a "direct box" for electric guitars or synthesizers. A 30 dB magnetic shield package is standard. Features: Converts unbalanced line levels to balanced mic level output Stops "hum and buzz" problems in musical instrument hook-ups Allows use of long cables without high frequency loss High...

    • RDL TX-LC2 Unbalanced to Balanced Line Combiner

      RDL TX-LC2 Unbalanced to Balanced Line Combiner

      The RDL TX-LC2 is the ideal choice in installations requiring the active, isolated mixing of two unbalanced line-level audio sources to feed a balanced (or unbalanced) audio line. The input circuits are high-impedance, line-level (-10 dBV) and are each isolated from each other. Therefore the modules may be used to bridge an unbalanced stereo source without affecting the stereo separation. The output from the TX-LC2 is a mono mix of the stereo signal. Gain of the combined signals is adjustable...
