AI-assisted summary

Description from the seller

Vintage Sansui 7 channels Equalizer with a reverberation amplifier! Made in Japan.

The Sansui RG-707 is a classic piece of "Silver Era" Hi-Fi gear from the early 1980s. It’s a versatile unit that combines a 7-band graphic equalizer with a reverberation amplifier, allowing users to both shape the
frequency response and add artificial "depth" or echo to their music.
Allow also to plug 2 microphones or 2 instruments (e.g. guitars), with their own each equalization.

Tested and working.

Key Technical Specifications:
Output Voltage 150mV (max 4V)
Frequency Response 20Hz to 20kHz
Signal to Noise Ratio 70dB
Total Harmonic Distortion 0.05%
Equalizer Control Range ±12dB
Equalizer Bands 60, 150, 400, 1k, 2.4k, 6k, 15k Hz
Reverb Time 0 to 3 seconds

Features & Functionality:

• Dual-Purpose Design: It functions primarily as an EQ to fix room acoustics, but the "Concert Hall" reverb feature was a popular gimmick of the era to simulate live environments.

• Visual Appeal: It features the iconic multi-color LED slide potentiometers and a display that glows, which was a hallmark of Sansui's aesthetic during the transition from analog to digital-look components.

• Tape Monitoring: It includes a tape monitor circuit, allowing you to EQ a signal before it hits your recording deck or monitor the playback through the EQ.

Dimensions 430 x 78 x 223mm

Pictures are part of the description. Comes with power cable (EU plug). 220 Volts unit.

Will be packed with extra protection for shipment.

Unit weight with cable: 2.7 kg
