Audio power amplifier | 800W | 70V / 100V / 4-16Ω | 230V | 483x337x49mm

Integrated Audio Power Amplifier – 800W, 70V / 100V / 4-16 Ω, 1U Rack, Class-D

Integrated power amplifier designed for professional sound reinforcement, background music and voice announcement systems where microphone, line and emergency announcement inputs, as well as a powerful 70V / 100V or 4-16 Ω speaker output, are required in one device. The 1U rack enclosure, Class-D amplification, forced cooling and protection against overheating, overload and short circuit allow the device to be used in commercial and public facilities.

• 800 W rated power – for larger sound reinforcement systems and speaker lines.
• 70V / 100V line outputs – for centralized public address systems.
• 4-16 Ω output – for compatible low-impedance speakers.
• Class-D amplification – for higher efficiency and lower energy losses.
• ALARM priority input – for emergency or evacuation announcements.
• Independent volume control – for microphone and line inputs.
• Line output – for transmitting signal to another amplifier.
• Protection against overheating, overload and short circuit – for safer operation.
• Forced cooling – for more stable operation under load.
• 1U rack enclosure – for professional installation in an equipment cabinet.

• Shopping centres – for background music, advertising and informational announcements.
• Schools and universities – for bells, announcements, classrooms, corridors and halls.
• Hotels – for reception areas, corridors, conference rooms and common areas.
• Manufacturing companies – for workshops, warehouses, administrative and technical zones.
• Office buildings – for general sound reinforcement and announcement systems.
• Sports and cultural facilities – for halls, foyers, waiting areas and public spaces.
• Evacuation announcement systems – where a priority ALARM channel is required.

For example, in a shopping centre, the amplifier is installed in an audio equipment cabinet. Ceiling or wall speakers placed in corridors, retail areas and common spaces are connected to the 100V line. A music player is connected to the AUX input, and a paging microphone is connected to the microphone input.

In normal mode, the system broadcasts background music, and when needed, an employee can transmit a voice announcement. When the ALARM channel is activated, the emergency announcement has the highest priority and can mute other audio sources.

For an audio system installer: suitable for 70V / 100V line systems and 4-16 Ω speaker solutions when a powerful 1U amplifier is required.

For a facility administrator: allows background music, microphone announcements and emergency announcement priority to be managed in one device.

For a public space: suitable for premises where clear speech, background music and reliable long-term operation are needed.

For a technical room: the 1U enclosure allows the amplifier to be neatly installed in a standard 19" equipment cabinet.

Before installation, it is necessary to choose the correct output mode and calculate the total speaker load. In 70V / 100V lines, the power of the connected speaker transformers is calculated, while in 4-16 Ω mode the permitted total impedance must be observed.

• Disconnect the amplifier power before connecting speakers.
• Do not mix a 100V line and 4-16 Ω speakers without a suitable solution.
• Do not exceed the amplifier’s 800 W rated power.
• Leave a power reserve, especially in 100V line systems.
• Ensure air circulation from front to rear.
• Do not cover air intake and exhaust openings.
• Test the emergency ALARM input function responsibly.
• Installation is recommended to be entrusted to an audio system specialist.

Quick selection guide

Choose an 800 W integrated power amplifier when you need a professional 1U device for a 70V / 100V line or 4-16 Ω sound reinforcement system with microphone, AUX and emergency priority functions.

800W amplifier for professional public address systems

The integrated 800W audio power amplifier is designed for facilities that require a reliable 70V / 100V line or 4-16 Ω sound reinforcement solution with microphone, AUX and emergency announcement functions.

Thanks to Class-D amplification, 1U rack enclosure, ALARM priority, line output, forced cooling, 50 Hz-16 kHz frequency range and protection against overheating, overload and short circuit, this amplifier is suitable for shopping centres, schools, hotels, offices, manufacturing companies and other professional sound reinforcement systems.
