Overview
The RAM Audio DENEB 2.5Q is a 4-channel power amplifier engineered to deliver high efficiency and versatility in professional fixed installation projects.
Providing a total power capacity of 2500 W, it features independent power distribution per channel. The amplifier directly supports low-impedance loads (2, 2.67, 4, and 8 Ohms) as well as 70V and 100V high-impedance (Hi-Z) distributed lines. With a wide operating voltage range of 90V-265V AC, it ensures stable performance against mains fluctuations. Weighing only 7 kg in a compact 2U (89 mm) rack space, the DENEB 2.5Q delivers pristine audio quality with less than 0.05% Total Harmonic Distortion (THD) and a 111 dB signal-to-noise ratio. It stands as a reliable and flexible power solution for demanding acoustic integration projects.
