Wharfedale DP-4035i Power Amplifier

Light on weight, Heavy on POWER

Stable down to 2 Ohms, DP-4035i is a 4-channel amplifier from our DP-i Series, designed specifically for fixed installations requiring power, flexibility and long-term reliability.

Delivering 450 W per channel at 8 Ω, 765 W at 4 Ω, and up to 1530 W bridged at 8 Ω or 4 Ω, it provides consistent performance across both low and high-impedance systems — including 70 V and 100 V Hi-Z operation. Built with installation practicality in mind, DP-4035i features Euroblock connectors, GPIO control and a rear-mounted power switch. A tamper-proof front grille protects the channel level controls for secure setup in public or commercial spaces.

Selectable input sensitivity (1 V or 0.775 V) ensures compatibility with a wide range of sources, while a wide-range AC input maintains stability in environments with fluctuating mains voltage. Efficient, durable and versatile — DP-4035i is the perfect amplifier solution for professional installed sound systems.
