The A33.2 is a two-channel modular power amplifier designed as the ideal output stage in a home theatre or hi-fi system. Its design is based on A30.2 technologies with a further simplification of the signal path.
Audiophile dual/mono circuit design
The A33.2 power amplifier is a dual-mono design, which means that each channel has its own identical, dedicated mono amplifier incorporating a heavy-duty custom-made toroidal transformer and low noise regulated power supplies. Each uses four ultra-fast bi-polar output devices in a push-pull configuration to preserve perfectly the fidelity of musical transients and minimize distortion.
The heat sinks are massive to keep the temperature at a moderate level even under the most difficult working conditions. The amplifier is capable of delivering 120watts into an 8 ohms load and incorporates full speaker protection against faulty input signals. One individual DC-servo for each channel together with protection circuit and temperature monitoring provide state-of- the-art protection.
