  • Annotazioni
  • The Sansui RA-990 is a reverberation amplifier designed to add depth and ambiance to audio signals. Unlike traditional spring reverb units, the RA-990 utilizes bucket brigade analog chips to create its reverb effect. This solid-state design allows for a more compact and reliable unit compared to mechanical spring systems.

    Technical Specifications

    • Frequency response: 20 Hz to 20,000 Hz
    • Input sensitivity: 1 mV (mic), 20 mV (line)

    Features

    • Multiple inputs and outputs via RCA connectors
    • Compatible with home audio systems and potentially usable for music production
    • Available in silver and black models

    Design and Construction

    The RA-990 shares technical similarities with its predecessor, the RA-900, but features an updated front panel design and green logo to match Sansui's newer product lines, such as the AU-D22 and AU-D33 series. This suggests that the RA-990 was part of a later generation of Sansui audio equipment, likely produced in the early to mid-1980s.
