JVC SEA-66 Graphic Equalizer
The SEA-66 was a Stereo Graphic Equalizer with built-in 10-band spectrum analyser, manufactured by the JVC Corporation. It also required an optional MU-S80 microphone for room acoustics calibration. Here are some of its features:
- 10 LED-lit frequency equalizer controls per channel
- 10-band real-time spectrum analyzer for frequency analysis
- Built-in pink noise generator for room acoustics compensation
- 3-deck connection with dubbing from 1 to 2/3, 2 to 1, 3 to 1.
- Selectable ±12 dB / ±6 dB control range
- S.E.A. defeat switch
Review
Although lower in the range than the SEA-M9, the SEA-66 had some wonderful features such as a bright display and LED-lit controls making it very attractive. The boost and cut was very prominent, and the electronic engineering very high quality.
