Description from the seller
The Pioneer SR‑9 is a dedicated stereo reverberation amplifier, built in the early 1980s, designed to add depth and ambiance to the audio signal of hi‑fi systems. It is a sonic processor that broadens the listening experience, allowing the simulation of different acoustic spaces from small rooms to large auditoriums.
User manual copy included.
Reviewed by a specialist technician.
Sound Functions and Processing
Adjustable reverb: reverb time control from 0 to 3 seconds in Echo mode — ideal for adding a wider “environment” to the music.
Duet Mode: by pulling the same control, it creates a “duet” effect, where a solo signal may sound as if performed by two sources.
Time/Depth Display: a dynamic visual indicator that graphically represents reverb time and depth — useful both aesthetically and functionally.
Sound Data (Electrical and Audio Specifications)
Frequency response range: 5 Hz – 70 kHz (well above the standard audible range, ensuring signal integrity without premature cutoffs).
Input sensitivity: 150 mV — compatible with common hi‑fi lines.
Output level: 150 mV.
Total Harmonic Distortion (THD): < 0.05%, indicating very low distortion added to the signal.
Signal-to-noise ratio: ~90 dB — good separation between the musical signal and background noise.
Physical Construction and Connectivity
Dimensions (L × H × P): approx. 420 × 99 × 336 mm — standard rackable hi‑fi component size.
Weight: about 4.3 kg, with robust metal construction and the classic front panel of the era.
Inputs/Outputs: dedicated stereo RCA connectors for reverb (in/out), in addition to connections for recording/rec.
Functional visual effect: front panel with LEDs indicating time/depth that “pulse” in time with the decay speed of the effect.
Electrical power: operation on standard 220 V AC.
To deliver this product properly, it is carefully packed in very sturdy boxes, wrapped in bubble wrap with ample packing material. We mainly use plastic as packing material, but if you prefer another material, please contact us. The package will be shipped insured to protect both the buyer and the seller. For special packaging requests, please send a message after purchase. Photos serve as an additional description of the product’s condition / display and LED status. Please check them carefully before purchase. Orders to remote islands or special destinations, such as the Canary Islands, will incur higher shipping costs.
