Detailed Product Description

The Qinsheng KTV158pro (Horizontal/7-Inch Display Edition) is a China-manufactured high-end 2.1 channel AI voice speaker designed to solve a common problem for outdoor performers and party hosts: reading song lyrics clearly without relying on a mobile phone screen. This all-in-one karaoke speaker is built for families, party organizers, team-building event planners, and outdoor entertainers who need professional-grade sound in a single portable unit.

Display & Song Selection

The unit features a 7-inch top-mounted display integrated directly into the chassis, allowing users to view lyrics and select songs without a secondary device. As part of the broader KTV158pro series, this model runs on Qinsheng's Android-based system architecture, supporting frequent song library updates and multiple selection methods, including touch, voice, and QR code scanning across the product line.

Audio Engineering

At the core of the KTV158pro is a 2.1-channel hi-fi sound system, combining a 6.5-inch woofer with dual midrange drivers and dual tweeters to deliver full, surround-quality sound suitable for both indoor gatherings and outdoor events. The speaker integrates a Mountainview DSP chip, a technology platform used across Qinsheng's karaoke lineup for professional anti-howling performance and clear vocal reproduction — critical for extended singing sessions in open or echo-prone environments.

Karaoke-Specific Controls

This AI voice karaoke speaker includes one-touch karaoke functions covering reverb effects, vocal removal (for instrumental-only playback), and adjustable bass/treble settings, giving users studio-style control without needing external mixing equipment.

Portability & Power

Designed for mobility, the KTV158pro (Horizontal Edition) includes a built-in handle/trolley design, making it easy to transport between venues. Its built-in battery supports up to 15 hours of continuous use, positioning it as a practical choice for all-day outdoor events, markets, or extended family gatherings.
