Description
The Adastra RS360 is a high-power 360W 100V line slave amplifier designed to expand and reinforce commercial audio systems with ease. Built for medium to large-scale installations, it delivers efficient Class-D amplification within a robust 2U rack-mount chassis, making it an ideal solution for extending speaker coverage across larger venues without replacing existing infrastructure.
Engineered for seamless integration, the RS360 allows installers to scale audio systems efficiently by adding additional power where required, maintaining consistent performance across extended zones.
High Power Output for Larger Installations
With a 360W RMS output, the RS360 is designed to drive larger distributed speaker systems, providing sufficient headroom for demanding commercial environments. It is particularly suited to:
- Retail spaces requiring extended background music coverage
- Bars, pubs, and restaurants with multiple audio zones
- Warehouses and industrial environments
- Schools and public address systems
- Hospitality venues with large floor areas
Its high output capability ensures consistent audio performance even across long cable runs and multiple speaker circuits.
Purpose-Built for Expanding 100V Line Systems
The RS360 is a dedicated slave amplifier, meaning it is designed to work alongside an existing mixer or amplifier. It accepts a line-level signal and amplifies it to power additional speakers or extend system reach.
A key feature is its 100V input, which allows the amplifier to connect directly to an existing 100V speaker line. This enables installers to expand systems from any point along the speaker cable, eliminating the need for additional signal runs and simplifying installation.
This makes it a highly efficient solution for system upgrades and expansions.
Efficient Class-D Amplification
Utilising Class-D amplifier technology, the RS360 delivers high output with reduced power consumption and minimal heat generation. This results in:
- Improved energy efficiency
- Lower operating temperatures
- Reduced rack space cooling requirements
- Lightweight construction for easier installation
The Class-D design ensures reliable performance in continuous-use commercial environments.
Flexible Connectivity and System Integration
The RS360 is designed for maximum installation flexibility, offering multiple input and output options:
- RCA and terminal block line inputs
- Line outputs for cascading additional amplifiers
- 100V input for system expansion
- Speaker outputs for both 100V line and low impedance systems
Slave input and output connections allow multiple amplifiers to be daisy-chained, enabling scalable system design for larger venues.
Dual Operation: 100V Line and Low Impedance
In addition to standard 100V operation, the RS360 supports low impedance speaker configurations, providing versatility for different system types.
This allows installers to:
- Use the amplifier in traditional 100V distributed systems
- Deploy it in low impedance setups where required
- Adapt installations without changing core equipment
This flexibility is particularly valuable in hybrid or evolving systems.
Emergency Mute Integration
The RS360 includes a 24V mute input, allowing it to integrate with fire alarm or emergency systems. When triggered, the amplifier can mute audio output to prioritise safety announcements.
This feature is essential for compliance in:
- Public buildings
- Education facilities
- Commercial premises
- Hospitality venues
It ensures the system meets modern safety and operational standards.
Installation-Ready Rack Design
Housed in a standard 2U 19-inch rack format, the RS360 is designed for straightforward installation into AV racks and equipment cabinets. Front-panel controls include master volume adjustment and LED indicators for signal and peak monitoring, allowing easy system management.
Its durable construction ensures long-term reliability in demanding environments.
Ideal Applications
The Adastra RS360 is widely used across commercial audio installations:
- Expanding existing 100V line systems
- Large retail and hospitality venues
- Multi-zone background music systems
- Public address and announcement systems
- Industrial and warehouse audio installations
Its ability to scale system power makes it a cost-effective upgrade solution.
