500W V2000 Amplifier Module

The Zenitel D-500 is a 500 W Class D amplifier module for V2000 and INTEGRA public address and voice alarm mainframes. It gives system designers an efficient, configurable amplifier channel that can be matched to the power needed by the loudspeaker circuit.

Main benefits and key functions

Zenitel specifies transformerless Class D amplification, low standby consumption and up to 500 W RMS output at 100 V. Output power is configurable in software across 25 to 500 W, and the line output can be selected as 100 V, 70 V or 50 V. This is the key difference between the D500 and the D150: this model offers substantially more available power for higher-load circuits. The selectable output voltage and power help match the amplifier channel to the actual loudspeaker circuit. Model choice should follow the designed load rather than automatically choosing the highest possible wattage.

Typical applications

The D500 suits supervised loudspeaker systems in commercial buildings, public venues and other voice alarm sites. Its configurable power helps the designer avoid unnecessarily oversizing individual amplifier channels. Both model types can be mixed within a host frame as the system design requires.

Connectivity and installation

Up to ten D150 or D500 modules can be housed in one V2000 or INTEGRA mainframe, according to Zenitel. The card is designed for those hosts and is not a standalone amplifier. The manufacturer identifies EN 54-16 certification as part of the PAVA arrangement. Confirm overall mainframe power limits, channel loading and any standby amplification before commissioning.

Specification and purchasing guidance

For installers and specifiers, the D500 should be matched to the host equipment, cabling and operating conditions shown on the project drawings. Keep the model number in the system schedule so future maintenance teams can identify the correct version. Check any optional accessories separately rather than assuming they are supplied with the base product.

Summary

The Zenitel D500 offers a focused solution for its documented role. Its main strengths are the specific functions and compatibility described above, making it a practical choice when those requirements are part of the installation. Order the exact version that matches the system design.
