PRX ONE Column Speaker System, Multiple Audio Source Control, Surround Sound Quality

The OMB Powered Column PA System combines a column speaker array, powered low-frequency section and integrated audio controls in one streamlined professional sound reinforcement system.

Designed for live events, conferences, presentations, entertainment venues and mobile PA applications, the system provides wide sound coverage while reducing the amount of separate audio equipment required for setup.

Automatic Feedback Suppression (AFS), Bass Boost, multiple audio source control and a detachable column design make it a practical solution for users who need clear speech, balanced music reproduction and convenient system deployment.

An All-in-One Column PA Solution

Traditional PA systems may require separate loudspeakers, amplifiers, speaker stands and additional signal-processing equipment.

A powered column PA system combines several of these functions into a more integrated platform.

The column section distributes mid- and high-frequency sound across the audience area, while the powered low-frequency section provides bass support and houses the system electronics.

This architecture is particularly useful for applications where users want:

● Faster setup and breakdown
● Less external equipment
● Cleaner stage or event layouts
● Easier system transportation
● Consistent sound coverage
● Convenient operation from one system

For event companies, presenters, musicians and AV integrators, this can simplify both temporary and semi-permanent sound reinforcement installations.

Microphone feedback is one of the most common problems in live PA systems.

When microphone gain is increased or the microphone is positioned too close to a loudspeaker, certain frequencies can circulate between the microphone and speaker and produce unwanted howling.

The integrated Automatic Feedback Suppression function helps identify and reduce problematic frequencies, improving system stability during microphone use.

This is particularly useful for:

● Conferences
● Corporate presentations
● Speeches
● Weddings
● Live vocal performances
● Training rooms
● Houses of worship
● Multipurpose halls

AFS does not replace correct microphone and speaker placement, but it provides an additional tool for controlling feedback in demanding sound reinforcement environments.

Wide Sound Coverage from a Column Speaker Design

One of the main reasons to choose a column PA system is its sound distribution characteristics.

The vertically arranged speaker section is designed to distribute sound across a broad audience area while maintaining a slim system profile.

All-in-One Column PA System Compared with a conventional point-source PA speaker in suitable applications, a column system can help provide more consistent sound across seating or standing areas.

Wide coverage is especially useful when sound needs to reach:

● Conference attendees
● Wedding guests
● Restaurant or lounge audiences
● Corporate event participants
● Small performance audiences
● Indoor multipurpose spaces

Actual coverage angle and recommended audience area should be confirmed according to the technical specifications of the system.

Bass Boost for Music and Event Sound

Speech applications mainly require intelligibility, but music-focused events also need sufficient low-frequency energy.

The built-in Bass Boost function enhances low-frequency reproduction when additional bass impact is required.

This gives users greater flexibility when switching between applications such as:

Speech Presentation
→ Prioritize vocal clarity and intelligibility.

Background Music
→ Maintain balanced, comfortable reproduction.

Live Music or DJ Playback
→ Increase low-frequency impact where appropriate.

The correct bass setting should always be selected according to the venue, program material and required sound level.

Multiple Audio Source Control

Professional events often require more than one audio source.

A PA system may need to handle microphones, mixers, playback devices or other professional audio equipment during the same event.

The OMB Powered Column PA System provides multiple audio source control functions, allowing users to manage different source requirements through the integrated system.

This can reduce dependence on additional external equipment for straightforward event configurations.

For more complex live sound applications, the system can also be integrated with an external professional mixer according to the required input count and signal routing.

Detachable Column Design

The column speaker section can be detached from the base system, making installation, storage and transportation more convenient.

This modular construction is useful for mobile professional audio applications where equipment is regularly:

● Transported between venues
● Installed for temporary events
● Packed after performances
● Stored in limited spaces
● Reconfigured for different sound systems

For rental companies and mobile event operators, convenient assembly can help reduce setup time between projects.

OMB focuses on professional audio products including professional power amplifiers, active speaker amplifier modules, DSP solutions and professional loudspeaker systems.

This broader audio engineering background allows OMB to approach a powered PA system from the interaction between amplification, signal processing and loudspeaker performance rather than considering the speaker enclosure alone.
