Kenwood EQ-60
The Kenwood EQ-60 is a 10-band stereo graphic equalizer. The paper trail is thin. No production years, original price or design details survive in the sources available. What is known is a consistent set of figures that several equipment databases agree on.
The EQ-60 has ten bands per channel centered at 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, and 16kHz. Frequency response runs 10Hz to 100kHz. Total harmonic distortion is rated at 0.003% and signal-to-noise ratio at 100dB. Input sensitivity is 150mV, with an output level of 1.5V. It measures 420 × 118 × 235mm and weighs 3.0kg.
HiFI-Stereo (June 1986, p.30) covered the EQ-60 in a car stereo context, noting that at line level, at least one — and preferably two — separate power amplifiers are required to drive the speakers used with it. HiFI-Stereo (June 1986, p.30) also reported lab measurements for the unit, including an FM mono usable sensitivity of 15.2 dBf. The magazine's lab measurements for the unit included an FM mono usable sensitivity of 15.2 dBf (1.6µV) at a 75-ohm input, and tape signal-to-noise ratio referred to 250 nWb/m at 315Hz.
