2. IP Speaker Technology Overview
What Are IP Paging Speakers?
IP paging speakers are network-connected audio endpoints that receive both power and audio through standard Ethernet cabling. Unlike traditional PA systems requiring dedicated speaker wire, power amplifiers, and analog distribution, IP speakers function as self-contained units that simply plug into your existing network infrastructure.
How IP Speakers Work
Network Connection
Each speaker connects to a PoE-enabled network switch using standard Cat5e or Cat6 Ethernet cable (maximum run: 100 meters/328 feet).
Power Delivery
Power over Ethernet (PoE/PoE+) technology delivers electrical power through the same cable that carries data, eliminating the need for separate power supplies.
Audio Protocols
IP speakers support three audio distribution methods:
- Unicast: One-to-one communication (specific speaker targeting)
- Multicast: One-to-many communication (zone-based broadcasting)
- Broadcast: One-to-all communication (facility-wide announcements)
Audio Quality
Digital audio transmission at 192 kbps provides clear, high-quality sound reproduction with minimal latency (typically <100ms).
3. IP Speakers vs. SIP Speakers: Which to Choose?
Linortek offers two distinct speaker technologies. Understanding the differences will help you select the right solution.

4. Speaker Selection Guide by Environment
Selecting the right speaker form factor is critical for optimal performance. Consider three factors: ambient noise levels, ceiling height, and coverage area.
Horn Speakers (30W)
Model: Netbell-H30-709 (IP) / Netbell-H30-709-SIP
Horns are typically used in manufacturing, warehouse, and outdoor environments, or open environments such as transportation centers.
Coverage Pattern
Horn speakers provide directional coverage with focused sound projection. Sound travels in a cone pattern, reaching farther distances.
Ideal Applications:
- Manufacturing facilities (85+ dB ambient noise)
- Warehouses and distribution centers
- Outdoor areas (loading docks, parking lots, courtyards)
- Open environments (transportation terminals, stadiums)
- High-ceiling facilities (20+ feet)
Installation Specifications:
- Mount height: 12-20 feet
- Mounting angle: 15-30° downward from horizontal
- Speaker spacing: 100-150 feet (varies with ceiling height)
- Coverage radius: 75-100 feet per speaker
Environmental Rating: IP65-rated
Power Requirements
– Input: 12VDC/24VDC/PoE – Consumption: 30W
Wall-Mount Speakers (20W)
Model: Netbell-WM-042 (IP) / Netbell-WM-042-SIP
Wall speaker can be used for hallways or offices/classrooms where drop ceiling is not available.
Coverage Pattern
Wall speakers project sound horizontally, providing consistent forward coverage along the wall-mounted plane. Ideal for linear spaces where listeners move past the speaker.
Ideal Applications:
- Hallways requiring forward coverage
- Areas where ceiling access is limited or unavailable
- Rooms with high ceilings (20+ feet)
Installation Specifications:
- Mount height: 7-9 feet (optimal speech intelligibility)
- Speaker spacing: 20-60 feet (depends on hallway width)
- Coverage: 30-40 feet forward projection
- Placement: Face primary direction of traffic
Mounting Considerations
- Use in pairs for bidirectional hallways
- Position above doorways to prevent obstruction
- Angle slightly downward (5-10°) if mounting above 8 feet
Power Requirements
– Input: 12VDC/24VDC/PoE – Consumption: 20W
Ceiling Speakers (30W)
Model: Netbell-CM-600 (IP) / Netbell-CM-600-SIP
For offices & classrooms.
Coverage Pattern
Ceiling speakers provide 360° omnidirectional coverage, distributing sound evenly throughout the space below. The “cone of coverage” extends downward from the speaker in a circular pattern.
Coverage Rule of Thumb
Space ceiling speakers 2X the ceiling height apart. For 10-foot ceilings, space speakers 20 feet apart.
Ideal Applications:
- Office buildings and corporate environments
- Classrooms and conference rooms
- Retail spaces and customer areas
- Restaurants, hotels, hospitality venues
- Any location with drop-tile ceiling (8-20 feet)
Installation Specifications:
- Ceiling height range: 8-20 feet
- Drop-ceiling tile mounting
- Avoid placement directly above noisy equipment
- Consider acoustic properties of room
Optional Features
The ceiling speakers come with talkback function, optional push button to initiate call for two-way communication.
Power Requirements
– Input: 12VDC/24VDC/PoE – Consumption: 30W
5. Communication & Control Modules
Live voice, pre-recorded messages, emergency alerts can be used with the Netbell IP speaker. Linortek offers multiple communication modules to suit different operational needs.
VoIP Phone System Integration
For IP Speakers: AU-711-SIP Paging Gateway
The AU-711-SIP serves as a bridge between VoIP phone systems and Linortek IP speakers. It registers as a SIP extension on your phone system and multicasts received audio to configured IP speaker groups.
How It Works:
- Register AU-711-SIP as extension on VoIP system
- Configure IP speaker groups in NACT software
- Program AU-711-SIP with speaker group multicast addresses
- Dial extension to broadcast to selected zones
Supported VoIP Platforms:
Cisco, Avaya, 3CX, FreePBX, Asterisk, Grandstream, and any SIP 2.0 compliant system
For SIP Speakers: Direct Integration
SIP speakers do NOT require the AU-711-SIP gateway. They register directly with your VoIP phone system as extensions.
How It Works:
- Register one SIP speaker per zone as a VoIP extension
- Configure that speaker to multicast to other speakers in the zone
- Dial the extension to broadcast to entire zone
Cost Advantage:
One VoIP license serves unlimited speakers through multicast. For a 50-speaker system, you might only need 3-4 VoIP licenses (one per zone) instead of 50 licenses or an expensive gateway.

6. Scheduling and Automation
Netbell-NTG-B Network Tone Generator
The NTG-B is the automation brain of your IP paging system. It schedules events, stores pre-recorded messages, and integrates with external systems.
Core Capabilities:
Event Scheduling
- 500 programmable time-based events
- Support weekday, calendar-based scheduling
- Conditional-logic task builder
- Automatic DST adjustment
- Independent schedules for different zones
Audio Library
- Built-in 40 standard tones and emergency messages

Zone and Tone Control System
The Netbell-NTG-B controls tone and message playback through a relay system. Each device has 8 total relays (2 physical + 6 virtual) that can be configured as either zone controls or tone triggers.
Important: You can mix and match these assignments, but the combined total cannot exceed 8 relays per NTG-B device.
Planning Examples:
- 1 zone configured = 7 relays available for tone triggers
- 4 zones configured = 4 tone triggers available
- 6 zones configured = 2 tone triggers available
- 7 zones configured = 1 tone trigger available
Multi-Device Capability:
Multiple Netbell-NTG-B devices can be used in a single system to enable additional location-based messaging beyond the 8-relay limit of a single device.
