Zone 4P is a 4-zone audio controller with onboard DSP and four channels of integrated 100W amplification — zone control and speaker drive in a single 2U unit. It manages up to four independent audio zones, each configurable for source selection, volume, EQ and speaker presets via WebApp, the browser-based interface built into every Zone controller. Automated daily schedules let the system run itself throughout the venue’s operating hours without manual intervention.
The integrated amplifier delivers 100W per channel at 4Ω or 8Ω, covering the power requirements of most small to medium commercial installations without the need for a separate amplifier. Channels can be bridged for 200W at 8Ω — useful for 70V constant voltage applications or where higher output is needed in a specific zone. Inputs cover the full range of commercial source requirements: four stereo line inputs, two mic inputs with 48V phantom power, and two HDMI inputs for TV and set-top-box audio.
Zone 4P pairs with ZonePad wall controllers to give venue staff in-room control in any zone. Alarm override is built in — the system mutes automatically on fire alarm trigger, a standard requirement for commercial venue installations. For installations requiring more than four zones, the Zone 8P provides the same integrated amplification approach across eight zones.

Optimal Audio Zone 4P FAQs
Zone 4P is a 4-zone audio controller with onboard DSP, WebApp and four channels of integrated 100W amplification. It combines zone control and speaker drive in a single unit — managing up to four independent audio zones for source selection, volume, EQ and speaker presets, while simultaneously powering the speakers directly. Channels can be bridged for 200W at 8Ω for 70V constant voltage applications. System configuration and daily scheduling are handled through WebApp, accessible from any device on the network. For most small to medium commercial installations, no separate amplifier is required.
The Zone 4P and Zone 4 share the same 4-zone DSP architecture, the same inputs and the same WebApp interface. The difference is amplification. Zone 4 is a controller only — it requires a separate power amplifier to drive the speakers. Zone 4P has four channels of 100W amplification built in, making it a single-unit solution for installations where a separate amplifier is impractical or unnecessary. Zone 4P is the natural choice for smaller venues or installations where simplicity and reduced rack space matter: a bar, a retail unit, a restaurant, a small hotel. Zone 4 is the better choice where the installation requires higher output than the integrated amplifier provides, or where an external amplifier is already specified. Both models are rack mountable and desktop mountable.
