Accuphase A-48 Amplifier

Pure Class A operation means the amplifier's output transistors are always conducting, which eliminates switching distortion. This results in a highly linear, smooth, and natural sound profile that is particularly prized for its detail and musicality.

Yes. The A-48 is specifically engineered to handle low-impedance loads, delivering up to 360 watts per channel into 1 ohm. Its robust 6-parallel push-pull circuit ensures stable performance even with demanding speaker designs.

Yes, the A-48 is bridgeable, allowing you to convert it into a monophonic amplifier. In this configuration, it can deliver up to 720 watts into a 2-ohm load, providing significantly more headroom for high-end speaker systems.

A damping factor of 800 indicates the amplifier's superior ability to control the movement of your speaker's woofer. This results in tighter, more precise bass response and prevents unwanted cone vibrations, leading to cleaner overall sound reproduction.

Yes, the unit features an advanced output protection circuit that monitors the speaker terminals. If a short-circuit is detected, the system will automatically engage to protect both the amplifier and your connected speakers from damage.

The gain selector allows you to adjust the sensitivity of the amplifier across four levels (MAX, -3dB, -6dB, and -12dB). This is useful for matching the amplifier to your preamplifier's output level and can also help optimize the signal-to-noise ratio in your specific system configuration.
