The HK Audio MC² Audio Delta 120 is a high-powered, network-ready amplifier engineered for demanding professional sound reinforcement. Designed around MC²’s industry-leading power amp technology, the Delta 120 delivers exceptional clarity, efficiency, and future-proof flexibility for both touring and installation environments.
With an impressive 2 × 4600W into 4Ω and over 6000W per channel into 2.7Ω, the Delta 120 runs cool and stable even under extreme loads. Its low-distortion design maintains pristine audio quality right up to full output, while intelligent limiter headroom ensures consistent performance even when mains voltage drops.
The rear panel offers effortless switching between analogue inputs and Dante digital audio, supported by high-quality 24-bit/96kHz conversion. When paired with a Delta DSP amplifier via a single CAT5 cable, the Delta 120 becomes the heart of a powerful stereo 3-way system with no additional processing required.
Flexible routing options, including adjacent input linking, allow the Delta 120 to adapt to any professional setup, whether used as a high-output networked amplifier or a robust traditional dual-mono unit.
