OSD Nero XMAX11 11-Channel Audiophile Home Theater Power Amplifier
The OSD Nero XMAX11 11-Channel Audiophile Home Theater Power Amplifier is the flagship multi-channel amplifier engineered for luxury reference home cinemas, delivering 140 watts RMS per channel into 8 ohms (200 watts RMS into 4 ohms) across all 11 channels driven. Featuring dual massive custom toroidal power transformers, modular channel architecture, discrete Class-A/B high-current output devices, balanced XLR inputs, gold-plated RCA inputs, and 12V trigger automation, the XMAX11 powers complete 7.2.4 or 9.2.2 Dolby Atmos and DTS:X systems.
If you want to know what single-chassis 11-channel power amplifier delivers reference cinema power for an entire 7.2.4 Dolby Atmos installation, how dual toroidal transformers eliminate dynamic sag during high-volume cinema peaks, or how balanced XLR connections provide dead-silent background noise levels in multi-seat luxury theaters, the OSD Nero XMAX11 provides the ultimate flagship solution. Premier cinema designers specify the XMAX11 for its unyielding current reserves, modular acoustic purity, and architectural excellence.
