Reports

• With a nominal output power (DIN) of 2 x 47 W at 4 Ω, the receiver Loewe TA 6000, type SX 6773 took the middle position in the Loewe Hifi series, but offered the same sophisticated technology as the "big ones". Thus, its distortion factor was 0.08% at 35 W (4 Ω). Convenience and connection options as with the "big ones": volume control with 41 detent positions, connections for two tape recorders, two record players, an aux, two pairs of speakers and stereo headphones.
