Description
The Optimal Audio Zone 4 is a professional four-zone audio controller with integrated DSP, designed to act as the central processing hub of modern commercial audio systems. Delivering flexible routing, advanced signal processing, and intuitive control, it enables independent management of multiple audio zones across hospitality, retail, corporate, and leisure environments.
Built for scalability and ease of use, the Zone 4 provides a powerful yet streamlined solution for multi-zone audio distribution without integrated amplification, allowing installers to pair it with external amplifiers tailored to project requirements.
Four-Zone Audio Control with Independent Configuration
The Zone 4 allows full control of up to four independent audio zones, enabling different sources, volume levels, and EQ settings to be applied to each area within a venue.
This enables:
- Independent audio experiences across multiple spaces
- Separate control of music and announcements per zone
- Optimised sound tailored to different environments
Typical applications include restaurants, retail stores, hotels, offices, and multi-room venues.
Advanced DSP Processing for System Optimisation
At the core of the Zone 4 is powerful digital signal processing, allowing precise system tuning and optimisation.
DSP capabilities include:
- Speaker presets and custom EQ per zone
- Flexible signal routing across inputs and outputs
- Audio optimisation for consistent performance
- Presets for fast system setup
This ensures high-quality, balanced audio across all zones regardless of layout.
Flexible Connectivity for Modern AV Systems
The Zone 4 offers a comprehensive range of inputs, including:
- 2 microphone inputs with 48V phantom power
- 4 stereo line inputs
- 2 HDMI inputs for TV and video audio
This allows seamless integration with:
- Media players and streaming devices
- Paging microphones
- AV systems and display audio
The inclusion of HDMI inputs is particularly valuable in hospitality environments where TV audio integration is required.
Configurable Outputs for Multi-Zone Distribution
The controller features four balanced line outputs, which can be configured as either four mono zones or two stereo zones depending on system design.
This enables:
- Flexible speaker system layouts
- Distribution of different sources across zones
- Integration with external amplifiers for scalable systems
WebApp Control for Simple Operation
A key feature of the Zone 4 is its intuitive WebApp interface, allowing full system configuration and control from any device with a web browser.
This provides:
- Remote access for setup and adjustments
- Simplified commissioning for installers
- Easy day-to-day control for end users
No additional software is required, significantly reducing setup complexity.
Paging and System Integration
The Zone 4 includes dedicated inputs for paging microphones and wall controllers via CAT5, enabling system-wide or zone-specific announcements.
Additional integration features include:
- Alarm override input for emergency systems
- Ethernet connectivity for network control
- Compatibility with Optimal Audio ZonePad wall controllers
This ensures compliance with commercial and safety requirements.
Scalable System Design
As a non-powered controller, the Zone 4 is designed to work with external amplifiers, providing maximum flexibility in system design. This allows integrators to scale systems based on venue size and performance requirements.
Installation-Ready Rack Design
Housed in a standard 1U 19-inch rack chassis, the Zone 4 is designed for straightforward installation into AV racks and equipment cabinets. Its compact footprint ensures efficient use of space while delivering full system control.
Ideal Applications
The Optimal Audio Zone 4 is widely used in:
- Bars, restaurants, and hospitality venues
- Retail stores and shopping environments
- Hotels and multi-room facilities
- Corporate offices and conference spaces
- Education and leisure environments
Its four-zone capability makes it ideal for small to medium multi-area installations.
