The Technics SH-8065 is a precision 33-band stereo graphic equalizer intended for careful optimization of loudspeakers and headphones in critical home environments.
This equalizer is best used to optimize a transducer's voicing. While audiophiles grasp for clues trying to use words like "nasal," "woolly," "etched," "distant," "hollow," "forward," "thin," "warm," "direct," "expressive" and so forth, the audio professional recognizes these as simple frequency response anomalies, easily rectified with subtle equalization.
Pink-noise noise-based room EQ was a misguided consumer fad from the late 1970s. Our ears distinguish direct sound from the reflected, making noise-based analysis irrelevant.
While it might seem more suited to a professional environment, it has only unbalanced 1/4" RCA connections, not balanced XLR.
The SH-8065 offers the usual ±12 dB adjustments, and offers a selectable ±3 dB range for precision equalization. In other words, pressing the ±3 dB switch makes the full range of the sliders only ±3 dB, which is ideal for making only the most precise and delicate adjustments to otherwise perfect audio systems.
An interesting feature is a switch to reverse the effects of equalization, in other words, it turns the boosts to cuts and vice versa.
The SH-8065 is the world's first 33-band EQ; previous equalizers stopped at 31 bands, while this Technics SH-8065 adds two more third-octave sliders, one at 16 Hz and one at 25 kHz, to allow precision equalization to just beyond the ends of the audio band.
Compared to ordinary 31-band equalizers, the SH-8065 is particularly useful for the precision equalization of extreme full-range systems, especially where subwoofer performance to 16 Hz and below is important.
