Know before you buy
Yes, the AHB2 is designed to drive challenging speaker loads as low as 1.4 Ohms with ease. Its high output current capability ensures stable performance even with speakers that typically demand a lot from an amplifier.
The THX AAA™ technology utilizes feed-forward error correction to virtually eliminate distortion. This results in an exceptionally clean, transparent sound that preserves the fine details of high-resolution audio recordings.
The AHB2 offers three gain settings (Low, Mid, and High) to help you match the amplifier to your DAC or preamplifier's output level. Use the lowest gain setting that allows you to reach your desired volume levels to maximize the system's signal-to-noise ratio.
Yes, the AHB2 is bridgeable. In bridged mono mode, it delivers significantly more power—up to 480 Watts into 6 Ohms—making it a powerful choice for demanding speakers or high-output requirements.
No, the AHB2 features fully electronic protection circuits. By avoiding mechanical relays, the amplifier ensures long-term reliability and prevents potential signal degradation over time.
The AHB2 features an exceptionally wide frequency response, extending from 0.1 Hz to beyond 200 kHz. This ensures that the amplifier can accurately reproduce the full bandwidth of high-resolution audio formats without phase shift or roll-off in the audible range.
