Four-Channel Network DSP Amplifier
SR-AMP-DSP41500
4 × 1500 W network amplifier — inbuilt DSP, Dante and FIR filtering.
A four-channel Class D network amplifier with onboard DSP, optional Dante and FIR filtering. It drives 1500 watts per channel into 8 ohms, 2800 watts into 4 ohms, or 3000 watts per pair in bridge mode, and supports 100V and 70V distributed lines directly. A 4.3-inch IPS touch screen and Windows control software handle configuration and monitoring.

Note: the source datasheet’s feature list quotes 4×1900W@8Ω and 4×3000W@4Ω, which conflicts with the specification table figures shown here (the table’s numbers are used above). All figures are nominal, per manufacturer data — please verify power ratings with Bronx before deployment.
