Description

The Adastra UX-240 is a high-power 240W 100V mixer amplifier with integrated Bluetooth, media playback, and microphone control, designed for commercial audio installations requiring increased output and flexible connectivity. Built in a compact half-width 1U format, it provides a powerful all-in-one solution for background music and paging systems across retail, hospitality, and public environments.

Combining amplification, source playback, and control into a single unit, the UX-240 simplifies system design while delivering reliable performance for medium to larger commercial spaces.

240W Output for 100V and Low Impedance Systems

The UX-240 delivers 240W RMS output, supporting both 100V line speaker systems and low impedance loads down to 2Ω, selectable via rear panel configuration.

This makes it ideal for:

• Larger retail environments and showrooms
• Bars, restaurants, and hospitality venues
• Offices and commercial spaces
• Schools and public address systems

The increased power output allows for more speakers or higher coverage compared to lower wattage models.

Integrated Media Player with Bluetooth Streaming

A built-in media player provides multiple audio source options, including Bluetooth 5.0 streaming, USB playback, and DAB+/FM radio, enabling flexible and convenient music playback without external devices.

This allows:

• Wireless streaming from smartphones and tablets
• Continuous playback via USB storage
• Access to digital and FM radio stations

This integrated approach reduces installation complexity and hardware requirements.

Microphone Input with Phantom Power and Priority

The UX-240 features a combination XLR/jack microphone input with switchable phantom power, supporting both dynamic and condenser microphones.

A VOX priority function automatically reduces background music when a microphone is active, ensuring clear announcements for paging and speech applications.

Flexible Input and Output Connectivity

The amplifier includes a range of connections for system integration:

• 1 x Mic/Line input (XLR/jack combo)
• 1 x Stereo RCA line input
• 1 x 3.5mm AUX input
• RCA line output for expansion

Speaker connections are provided via screw terminals, supporting 100V line, low impedance, and common connections for flexible installation.

Compact and Installation-Friendly Design

The UX-240 features a half-width 1U chassis, allowing two units to be mounted side-by-side in a standard 19-inch rack or installed discreetly under counters or on walls.

This makes it particularly suited to:

• Space-constrained installations
• Retail counters and service areas
• Equipment racks and AV cabinets

Simple Control with EQ Adjustment

Front-panel controls include master volume, source selection, and bass and treble EQ, allowing quick adjustment of system performance to suit different environments.

This ensures:

• Easy operation for end users
• Fast tonal adjustments
• Minimal training requirements

Emergency Mute and System Integration

A 24V emergency mute contact allows the amplifier to be connected to fire alarm or evacuation systems, automatically muting audio when triggered.

This makes the UX-240 suitable for:

• Public address systems
• Safety-compliant installations
• Commercial buildings requiring emergency override

Efficient Class-D Amplification

The UX-240 utilises Class-D amplification with a transformer output stage, delivering efficient operation with reduced heat and power consumption while maintaining reliable performance.

Ideal Applications

The Adastra UX-240 is widely used in:

• Retail and background music systems
• Hospitality venues and bars
• Offices and commercial environments
• Education and training facilities
• Public address and paging systems

Its combination of higher output power and integrated features makes it particularly suited to medium-sized installations.
