The QFX PBX-1211 is a portable battery speaker designed for versatile audio playback and control, featuring a range of input options, light effects, and app-based management.
The PBX-1211 serves as a multi-functional audio system, offering FM radio, Bluetooth connectivity, USB card playback, and a Line In input. It includes a built-in equalizer for sound customization and LED light effects to enhance the user experience. The device can be controlled directly via its panel or through a dedicated smartphone application, "Speaker Pro."
In FM radio mode, users can automatically scan for radio programs by pressing the "SCAN" button or manually adjust the radio frequency between 87.5MHz and 108.0MHz using the TUNER button. The device allows for saving scanned stations and switching between them.
The speaker can connect to Bluetooth-enabled devices (phones, tablets, etc.) by selecting "Bluetooth Control" on the speaker and then choosing "QFX PBX-1211" from the device's Bluetooth settings. Once connected, audio can be streamed wirelessly. The "Speaker Pro" app further extends control over Bluetooth functions.
For wired audio connections, the speaker features a Line In input. Users can connect an external audio source, and the device will play the audio. A mute function is available for this input.
The speaker supports USB card playback, allowing users to play music files directly from a USB drive. The "Speaker Pro" app provides a dedicated interface for managing and playing songs from the USB card, including pause, play, backward, forward, and volume adjustments.
The PBX-1211 offers sound customization through its equalizer. Users can adjust volume, bass, and treble. It includes four pre-set EQ modes: Dance, Classical, Jazz, and Rock. Additionally, a graphic equalizer (G-Eq) is available for more detailed sound adjustments, accessible via the "Sound Set" page.
The speaker incorporates LED light effects with adjustable brightness and various color change modes. Users can select from 12 pre-set light effect modes, including "Heart" and "Sun." These effects can be controlled via the panel or the "Speaker Pro" app.
The device supports TWS functionality, allowing two QFX PBX-1211 speakers to be paired wirelessly for a stereo audio experience. This feature works in both Bluetooth and FM modes.
The manual does not explicitly detail maintenance features beyond basic operation. However, the robust design with multiple input options and app control suggests a user-friendly experience that minimizes complex maintenance. The DC9V power supply indicates a standard charging method. The ability to control the device via an app and its various input modes ensures flexibility and adaptability to different usage scenarios, potentially reducing wear and tear on physical controls.
