Wharfedale Pro DP-8015i 8-Channel 150W Installation Amplifier

Wharfedale Pro DP-8015i 8-Channel Class D Fixed Installation Amplifier

The Wharfedale Pro DP-8015i is a professional 8-channel Class D installation amplifier delivering 150W per channel across low-impedance (2–8Ω) and high-impedance (70V/100V) systems. Switchable to Bridge mode for up to 4 x 300W output, the compact 1U DP-8015i handles complex multi-zone audio distribution with consistent, reliable power across every configuration.

For integrators evaluating the best 8-channel amplifier for commercial installation — whether for houses of worship, retail environments, hospitality venues, or corporate campuses — the DP-8015i delivers the routing flexibility that demanding fixed install projects require. A front-panel 1.8″ color display provides immediate access to system status, while Lo-Z/Hi-Z/70V/100V/Bridge/Mono mode switching via a dedicated mode switch means a single unit covers virtually any distributed audio topology without additional equipment.

Built for professional AV installation environments, the DP-8015i uses Phoenix connectors throughout — inputs, outputs, and remote level adjustment — ensuring secure, field-serviceable terminations. GPIO functionality enables remote control and system linking for scalable multi-zone deployments. With a signal-to-noise ratio of ≥100 dB, a damping factor of 300, and THD+N of just 0.05% at 10% rated power, the DP-8015i meets the performance standards expected in permanent installed sound systems. Onboard protection against under-voltage, DC faults, over-temperature, overload, and short-circuit conditions ensures long-term reliability in critical installations.

Key Features of the Wharfedale Pro DP-8015i Installation Amplifier

• 8-Channel Class D Topology: Delivers 150W per channel across 2Ω, 4Ω, and 8Ω loads — stable performance at low impedance eliminates speaker system design compromises.
• Bridge Mode Output: Switches to 4 x 300W bridged operation, doubling available power per zone for applications requiring higher SPL without adding rack units.
• Lo-Z / Hi-Z / 70V / 100V Switching: A single front-panel mode switch configures the amplifier for both low-impedance and distributed high-impedance systems, making it adaptable to nearly any installed audio architecture.
• GPIO Remote Control & Linking: Enables integration with building control systems and external automation hardware for centralized multi-zone management.
• Phoenix Connector I/O: Screw-terminal Phoenix connectors on all inputs, outputs, and remote level ports provide reliable, vibration-resistant connections suited to permanent installation.
• 1.8″ Color Front Display: Provides at-a-glance system status and configuration data, reducing troubleshooting time during commissioning and maintenance.
• Comprehensive Onboard Protection: Under-voltage, DC, over-temperature, limiter, overload, and short-circuit protection safeguard both the amplifier and connected speaker systems.
