Sonance PowerZone Connect 504 500W 4-Channel DSP Power Amplifier

Sonance PowerZone Connect 504 500W 4-Channel DSP Power Amplifier

The Sonance PowerZone Connect 504 is a 500W, 4-channel Class-D power amplifier designed for professional distributed audio installations. Featuring integrated digital signal processing (DSP), flexible loudspeaker compatibility, and automatic power sharing, this compact amplifier supports both low-impedance and constant-voltage speaker systems. Its half-rack, 1U design provides installation flexibility for commercial audio environments where equipment space is limited.

Designed for commercial integrators and professional AV installers, the PowerZone Connect 504 delivers four channels of 125W amplification at 4 or 8 ohms or two channels of 250W at 70V or 100V. This flexibility makes it suitable for background music systems, multiroom audio distribution, paging applications, and commercial speaker installations. Automatic power-sharing technology distributes available output power according to system requirements, helping installers accommodate different loudspeaker configurations without unnecessary equipment complexity.

The integrated PowerZone Control web application provides browser-based access to amplifier configuration and DSP adjustments. Installers can manage multizone audio routing, input mixing, equalization, signal priority, ducking, speaker presets, high-pass filtering, and audio delay. Ethernet connectivity and built-in Wi-Fi provide convenient network access for system configuration. Balanced microphone/line inputs, unbalanced RCA connections, and S/PDIF digital connectivity support integration with professional audio equipment. With a compact enclosure, flexible audio routing, and a five-year manufacturer warranty, the PowerZone Connect 504 offers a practical amplification solution for commercial audio installations.

Flexible 500W Amplification for Commercial Audio

The PowerZone Connect 504 accommodates conventional low-impedance speakers and transformer-coupled constant-voltage loudspeakers. This versatility allows installers to configure the amplifier for different commercial sound system architectures without requiring separate amplifier models.

Low-Impedance Speaker Operation

In low-impedance mode, the amplifier delivers four independent channels rated at 125W each into 4- or 8-ohm loads. The PowerZone Connect series supports conventional loudspeaker impedances ranging from 4 to 16 ohms, providing flexibility when designing distributed audio systems.

70V and 100V Distributed Audio

For constant-voltage applications, the amplifier provides two channels rated at 250W each at either 70V or 100V. These configurations support transformer-coupled loudspeakers commonly used in commercial background music and voice distribution installations.

Integrated DSP and PowerZone Control

The built-in PowerZone Control web application provides access to a comprehensive selection of digital audio processing tools. Installers can customize signal routing, configure multiple audio zones, and optimize connected loudspeakers through a browser-based interface.

Audio Processing and System Configuration

• Multizone Configuration: Organizes audio distribution across independently configured system zones.
• Input Mixing: Combines and manages input signals according to installation requirements.
• Priority and Ducking: Adjusts signal levels automatically when priority audio sources require attention.
• Input and Output Equalization: Provides frequency-response adjustments for connected audio sources and loudspeakers.
• High-Pass Filtering: Controls low-frequency signal content to accommodate speaker system requirements.
• Speaker Presets: Provides preset-based configuration options for supported loudspeaker applications.
• Audio Delay: Enables timing adjustments for coordinated audio distribution.
• S/PDIF Output Routing: Supports configurable digital audio signal routing.
• Wall-M Controller Configuration: Provides configuration options for compatible Wall-M control systems.
• Sine Wave Generator: Provides a signal-generation tool for system setup and testing.

Professional Audio Connectivity

The amplifier incorporates balanced and unbalanced analog input connections alongside digital audio interfaces. Four balanced microphone/line input channels use Euroblock connections, while RCA connectors accommodate unbalanced analog sources. Four output channels use Euroblock connectors for supported high-impedance and low-impedance speaker configurations.

An S/PDIF digital input and output provide additional audio connectivity and routing options. General-purpose input/output connections support system integration, while RJ45 Ethernet and integrated Wi-Fi allow access to amplifier configuration functions.

Compact Installation and System Integration

The PowerZone Connect 504 features a 1U half-rack chassis measuring 8.7 inches wide, 1.7 inches high, and 12.6 inches deep. Its compact construction is intended for space-conscious commercial AV installations. The amplifier is not specified as rack-mountable, so installers should account for the appropriate mounting arrangement when planning equipment layouts.

The included adhesive rubber feet accommodate placement on suitable equipment surfaces. The amplifier operates within an ambient temperature range of 32°F to 104°F and includes a five-year manufacturer warranty.
