The Audio Choice QM4 (by SoundTech) is a 4-channel powered PA mixer designed for "gigging musicians" who need a portable, durable setup for small rooms and karaoke. While "better" is subjective, it excels in simplicity and physical control compared to modern digital-only interfaces that lack tactile feedback. Key Features & Benefits

Tactile Power: Includes weighted knobs and notched EQs, offering a physical feedback loop that digital apps often lack.

Hybrid Amplification: Uses a "Hybridtec" system that combines digital low-end efficiency with an analogue high-frequency section to avoid the "harsh" sound of some budget digital units. The Audio Choice by SoundTech QM4 is a

Simple I/O: Features combo 1/4" and XLR inputs on each of its four channels, making it versatile for microphones and instruments alike.

Gig-Ready Build: Encased in heavy-duty birch ply wood with a steel grille, specifically crafted to endure "harsh conditions" on the road. Why Manual Controls Can Be Better For many users, having a manual interface like the is preferable for live environments:

Adaptability: An engineer can make instant, physical adjustments based on the room's specific acoustics without menu-diving.

Reliability: Manual tuning relies on your ears and basic tools, avoiding the hardware-software handshake issues common with calibration microphones and apps.

Sound calibration software vs manual tuning: Which is better?

has long been a favorite for those who want hi-fi sound without the complexity of a multi-speaker setup. While its "set it and forget it" design is a selling point, the most power-users agree: you get a much better experience when you stop letting the soundbar make decisions for you. 1. Override Automatic Source Selection

The QM4's most divisive feature is its automatic source switching, which prioritizes inputs based on active signals. If you have a TV on Optical and a music streamer on the RCA inputs, the soundbar might jump between them unexpectedly.

The Fix: You can manually override this by using the Source button on the unit or the remote control.

Why it’s better: Manually selecting your input ensures your audio doesn't cut out or switch mid-movie if a secondary device wakes up. Note that the unit will revert to automatic mode once it enters standby, so make manual selection part of your "power-on" routine for critical listening. 2. Manual EQ through Placement

lacks a digital screen or complex EQ app, which means your "manual" tuning happens in the physical world.

Clear the Path: Ensure the BMR (Balanced Mode Radiator) drivers aren't obstructed. Unlike traditional speakers, these drivers provide a very wide "sweet spot," but they need a clear line of sight to fill the room properly. Surface Dampening:

If the bass feels "boomy," try pulling the soundbar a few inches away from the wall or placing it on a dampening mat. Because the

has a built-in subwoofer, vibrations can travel through your TV stand; isolating it manually tightens the low-end significantly. 3. Wired vs. Wireless

supports aptX Bluetooth, the "better" audio choice is always a manual wired connection.

Optical (Toslink): Best for TV and movies to ensure 2.1 audio remains crisp. 3.5mm / RCA:

If you are using a high-quality external DAC or a turntable with a pre-amp, use the analog inputs. The internal processing on the

is excellent, but feeding it a clean analog signal often yields a warmer, more "musical" profile than Bluetooth. 4. Know Your Status Lights
