Special Features
- Super Linear Circuit (SLC): by cancelling the non-linearity of one component with the complementary non-linearity of the other, the lowest possible distortion, higher stability and flat frequency response are achieved. Overall, better sound reproduction is achieved thanks to the excellent open-loop frequency response.
- Six-position recording selector switch.
- Honeycomb-ribbed chassis, honeycomb-structured heat sink and honeycomb damper feet to protect against resonance and microphonic effects.
- Digital sound quality even at low impedances: High stability to impedance curve fluctuations.
- "Non-Switching" Type II: Amplification without switching distortion; improved thermal stability and high linearity for natural sound.
- Direct Connection: Signal reaches the output via the shortest possible path, contributing to sound purity.
- Clean Ground System: Ground side free of leakage components due to chassis isolated from transformers and heat sinks.
- DIRECT switch: For direct connection to the volume control.
- Outputs for two pairs of speakers: Choice of separate or common operation.
- High-gain phono equalizer amplifier.
