This Pioneer SG‑540 is a fully functional 7-band stereo graphic equalizer from 1985. The unit is in great condition, with all LED-indicators shining bright. 

The SG-540 is designed for precise tone shaping. It offers low noise, wide frequency response, and classic Pioneer aesthetics. Each channel offers 7 frequency bands: 60 Hz, 150 Hz, 400 Hz, 1 kHz, 2.4 kHz, 6 kHz, and 15 kHz – with a ±10 dB control range per band. The layout is straightforward, with responsive sliders and clear LED indicators for both channels.

This unit features a flat frequency response from 5 Hz to 70 kHz, a signal-to-noise ratio of 100 dB, and total harmonic distortion of just 0.005%, making it suitable for both hi-fi listening and system calibration.

Output level is 1 V nominal (6 V max), with unity gain. It connects easily between your amplifier and source or in a tape monitor loop, and works equally well in vintage or modern setups.

Cosmetically, the unit retains its classic mid-‘80s Pioneer design with a black finish, silver sliders, and a clean layout. All sliders move smoothly and respond accurately. The silver frontplate is in great shape. The black casing looks smooth and clean, with just light signs of wear on top.

It will be packaged with care – in a strong box with layered protection – based on extensive experience in shipping vintage audio gear.
