The DUBHE Series are high-efficiency, 4-channel installation amplifiers built for mid-to-high power fixed installations where on-board DSP is not required. They share the same class D topology and universal PFC power supply as the DENEB Series, but are configured via rear-panel DIP switches and output level trimmers rather than a touchscreen processor — making them a straightforward analogue solution for installations where signal processing is handled externally.

DUBHE amplifiers support low impedance operation at 2, 4, and 8 ohm, and high impedance modes at 35V, 50V, 70V, and 100V. RAM Audio’s Power Control Management (PCM™) handles dynamic power distribution across channels. Configurable features include bridge mode, subsonic filter, signal link, output mode selection, and per-channel gain adjustment.

Models are available at 2,500W (2.5Q), 5,000W (5Q), and 10,000W (10Q) total output. Optional Dante™, AES67 (ATMOS/RAVENNA compatible), and GPIO modules are available. Phoenix connectors are used for all inputs and outputs. As with the DENEB, the inverted chassis design keeps fan intakes clear of dust.
