  • Remarques

  • An electronic 10 band stereo graphic equalizer with spectrum analyser housed in a metal case with an infrared remote control. The 10-band equalizer boosts and cuts up to 10dB at 10 frequency bands, channel by channel. The 10-band spectrum analyzer monitors the frequency makeup of music, channel by channel. With 5 programmable equalization patterns to create ones own equalized curves and store them in memory, and 5 resident equalization patterns, five equalized curves called HEAVY, CLEAR, SOFT, VISUAL and VOCAL, are stored in memory for instant recall. With RCA phono sockets for input/output to the Analyzer and Rec/Play for Tape, terminals for wired system control and an AC outlet.
