  Das zweitkleinste Modell der für das Modelljahr 1972 vorgestellten 22er Receiver Serie.(2215, 2230, 2245, 2270) Dieses Gerät wurde mit kleinen Änderungen bis 1975 gebaut. Es gab gravierte oder bedruckte, alu- oder champagnerfarbene ("gold-anodized") Frontblenden. Die Ausgangsleistung des 2230 wurde vom Hersteller, sehr konservativ, mit 2 x 30 Watt Dauerleistung bzw 2 x 45 Watt Musikleistung, nach RMS (20-20kHz), an 8 Ω angegeben.

  Im Katalog 1974 (Superscope) wurden dann auch circa Werte nach DIN angegeben.

  • 2 x 43 Watt sinus bzw 2 x 64 Watt Musikleistung an 4 Ω
  • 2 x 44 Watt sinus bzw 2 x 66 Watt Musikleistung an 8 Ω        

  3-fache Klangregelung (Höhen, Mitten, Tiefen), Vor und Endstufe auftrennbar, Feldstärkeanzeige, Muting für UKW, einstellbar, Leistungsaufnahme 220 Watt.

  Gegen gesonderte Berechnung war ein Holzgehäuse (WC-22) lieferbar.
