• 140W per channel output into 8 ohms; capable of prolonged output into 2 ohms with no discernible impact on performance.

• Bridged power amplifier configuration for maximised open and closed-loop speed, with ten stages of local regulation per channel.

• Two-box configuration with 500 PS power supply for optimum rejection of electromagnetic interference.

• 1,100VA toroidal transformer provides 12 raw DC supplies for the power amplifier. 

• 25kg brushed, black-anodised chassis with distinctive heatsink plus variable speed intelligent fan system for discreet extra cooling if required.

Craft and Technology

The NAP 500 delivers 140W per channel and can output to 2 ohms without any performance impact. It has a two-box configuration with a separate 500 PS power supply for ultimate performance. Each channel includes ten stages of local regulation, and the 500 PS provides twelve raw D.C. supplies for the power amplifier.

The bridged configuration in the NAP 500 amplifier allows for high speed, less intrusive protection circuitry and reduced interaction between input and output signals. It also features the new output transistor, NA009, designed for maximizing bandwidth and reducing distortion. The circuit topology minimizes power supply dependency and thermally-induced noise.
