240W 8-Zone IP Network Power Amplifier
8 x Independent 100V Zones • LCD Display • Infrared Remote • EMC Priority • Fire Alarm Linkage • Intelligent Power Management
T-77240Z
Complete 8-zone amplification in a single unit. The T-77240Z is a 240W IP network power amplifier with eight independent 100V zone outputs. Each zone can be individually addressed from the T-7700RP server, allowing simultaneous paging to different areas, background music zoning, and emergency evacuation routing – all with built-in amplification. No external amplifiers required.

The T-77240Z has a total power budget of 240W shared across eight zones. Power can be allocated dynamically – for example, Zone 1 can use 100W while Zones 2-8 share the remaining 140W, or all zones can be limited to 30W each. Per-zone power limits are configurable via software to prevent overload. Ideal for applications with varying zone size requirements.
The T-77240Z is a unique 8-zone IP network power amplifier that combines multi-zone routing with built-in amplification. Unlike separate decoder + amplifier solutions, the T-77240Z receives network audio, routes it to any of eight independent 100V zones, and amplifies it internally – all in a single 2U rack chassis.
Complete Zone Amplification: Each of the eight zones is a dedicated 100V constant voltage output with its own amplifier stage. Zones can be activated individually, in groups, or all simultaneously. This eliminates the need for external amplifiers and complex wiring, significantly reducing installation time and cost.
Flexible Power Distribution: With 240W total power, the T-77240Z can drive a mix of small and large zones. A school might use 30W for each of 8 classroom wings (240W total), while a retail store might allocate 100W to the main sales floor and 20W each to seven smaller areas. Power limits are software-configurable per zone.
Fire Alarm Integration: Dedicated fire alarm linkage inputs allow emergency messages to override any zone with highest priority. Programmable evacuation patterns (e.g., alternate zone activation) comply with international life safety standards.
Local Audio Inputs: Front/rear MIC and AUX inputs allow local announcement capability without network dependency. The EMC input provides absolute priority override for emergency paging.
Individual zone control with built-in amplification. No external amplifiers needed. Per-zone volume and source routing.
Direct interface with conventional fire panels. Programmable zone activation patterns for phased evacuation.
Per-zone auto standby reduces energy consumption. Zones power up only when audio is present, with configurable timeout.
Full-function IR remote for zone selection, volume, source switching, and emergency override. Range: 8 meters.
| Zone | Output Type | Max Power (Configurable) | Typical Applications |
|---|---|---|---|
| Zone 1-8 | 100V Constant Voltage | 0-240W per zone (total ≤240W) | Classrooms, retail departments, office floors, hotel conference rooms |
Power limits are set via T-7700RP software. The amplifier automatically manages total power to prevent overload. Example configurations:
| Trigger | Programmable Actions | Example |
|---|---|---|
| Fire Input 1 | Activate zones 1,2,3 at 100% volume, play emergency message | Zone 1-3 evacuation |
| Fire Input 2 | Activate zones 4,5,6 at 100% volume, play alternate message | Zone 4-6 evacuation |
| EMC Input | Activate ALL zones, highest priority, overrides fire inputs | Total evacuation |
EN54 compliant
programming available
Each zone has independent power management. Zones enter standby (near-zero power consumption) when no audio is present for a configurable period (5-60 minutes). Zones power up instantly (within 0.5 seconds) when audio is detected. This can reduce overall power consumption by up to 70% in multi-zone installations.
| Model | Total Power | Zones | Output Type | Form Factor | Best For |
|---|---|---|---|---|---|
| T-77240Z | 240W | 8 | 100V | 2U | Schools, retail, offices |
| T-77350Z | 350W | 8 | 100V | 2U | Larger venues, hospitals |
| T-77500Z | 500W | 8 | 100V | 3U | Stadiums, factories, airports |
The T-77240Z has a total power budget of 240W shared across 8 zones. Ensure total speaker wattage connected to all zones does not exceed 240W. Use the T-7700RP software to set per-zone power limits and prevent overload. Example: 8 zones × 30W speakers = 240W total.
Zones can be logically grouped in the T-7700RP software. For example, create an "All Call" group that activates zones 1-8 simultaneously, or "East Wing" group with zones 1,2,3. Group paging can be triggered from any T-7702A/M paging microphone with a single button press.
