Audio Choice Qm4 Manual 🎁 Essential
6.1. Multi-Source Mixing The QM4 allows for up to four distinct audio sources to be mixed simultaneously. For example, a karaoke setup might use Channels 1 and 2 for microphones and Channels 3 and 4 for background music players. Each source has independent EQ to prevent frequency masking (e.g., cutting bass on microphones to reduce rumble).
6.2. Zone Control (Output Impedance) The amplifier supports both low-impedance speakers (direct connection of a few speakers) and high-impedance distributed systems.

The handheld microphones use a simple interface to manage power, volume, and channel selection. Power On/Off: Press and hold the Power Button.
Battery Installation: Unscrew the microphone base to reveal the compartment. Insert 2 x 1.5V AA batteries.
Channel Switching: Press and hold the Set Button for approximately 4 seconds until the display blanks. The unit will cycle through channels in the order A, B, C, and D. Volume Adjustment: Press the Set Button once to enter volume mode. Press the Set Button again to adjust the level. The device exits this mode after 5 seconds of inactivity.
Button Lock: To prevent accidental changes, press and hold both the Set and Power buttons simultaneously for 3 seconds. Repeat to unlock. Receiver & System Operations
The system uses UHF frequencies (typically 902-928MHz depending on your specific region) to provide digital audio transmission.
Connection: Ensure the receiver is connected to your mixer or amplifier using the balanced XLR or unbalanced 1/4" jack outputs.
Signal Monitoring: The receiver will display Signal Strength icons when the microphone is successfully paired and within range.
Mute Function: Depending on the specific firmware version, some QM4-style handhelds allow muting by double-clicking the volume or power key. Troubleshooting Guide If you encounter issues, check these common solutions:
No Sound: Verify the transmitter is not in "Mute" and check if the receiver's volume is turned up.
Interference: If you hear static or other voices, use the Set Button to switch all components to a different channel (A, B, C, or D) to find a clearer frequency.
Distortion: If the audio is too loud or clipping, turn down the Volume on the receiver or the Gain on your mixer.
Power Issues: If the LED doesn't light up, ensure the power adapter is securely connected to both the wall and the receiver. PROFESSIONAL WIRELESS MICROPHONE SYSTEM MANUAL

Audio Choice QM4 (often branded as Audio Choice by SoundTech
) is a 100-watt, 4-channel powered PA mixer head typically sold as part of the C100 portable system. While a formal digital manual is rare, the device's straightforward analog design allows for easy operation based on its physical controls.

The Audio Choice QM4 is a professional 4-channel passive microphone mixer designed to combine up to four microphone signals into a single output. It is a utility tool commonly used in simple PA setups, small recording projects, or situations where a powered mixer is unavailable. Device Overview
The QM4 is a passive device, meaning it does not require a battery or external power source to operate. It uses internal transformers and resistors to manage the signals. Because it is passive, it does not provide gain; instead, it provides attenuation (reduction) of the input signals to balance them. Key Features Four independent XLR female inputs. One XLR male output. Individual volume control knobs for each channel. Passive circuitry (no power required). Rugged metal chassis for durability. Setup and Connection Connect your microphones to any of the four XLR inputs.
Connect the XLR output of the QM4 to your amplifier, powered speaker, or recording interface.
Start with all volume knobs turned fully counter-clockwise (off).
Slowly turn up the knob for the primary microphone until you reach the desired level.
Adjust the remaining knobs to blend the other microphones into the mix. Operating Requirements and Limitations
Dynamic Microphones Only: Since the device is passive, it cannot pass Phantom Power (48V). Do not use condenser microphones with the QM4 unless they are self-powered by their own batteries. Key Features of the Audio Choice QM4 Manual
Signal Loss: Being a passive mixer, there is a natural "insertion loss" of signal strength (typically around 6dB to 10dB). You may need to turn up the gain on your amplifier or powered speaker to compensate.
Impedance: It is designed for low-impedance (Lo-Z) microphones. Using high-impedance equipment may result in significant signal degradation or noise. Troubleshooting
No Sound: Ensure all cables are fully seated and that your output device (speaker/amp) is turned on and turned up.
Weak Signal: This is normal for passive mixers. Increase the volume on your destination device.
Distortion: Ensure you are not sending a line-level signal (like from a CD player or keyboard) into the mic inputs, as this will overdrive the internal transformers.
Hum or Buzz: Use shielded XLR cables and ensure the mixer is not sitting directly on top of a large power transformer or amplifier.
⭐ Pro Tip: For the best signal-to-noise ratio, keep your microphone cables as short as possible and use the highest gain setting available on your speaker or amplifier rather than cranking the QM4 knobs to their absolute maximum.
You can adjust the technical details (battery size, button labels, etc.) based on the actual physical product.
Bluetooth version: 5.0 (typical)
Wireless range: Up to 10 meters (33 feet) open space
The AudioChoice QM4 manual is functional for basic setup but falls short for advanced users. If you’re a beginner plugging into a phone or laptop, you’ll be fine. If you need to understand gain levels, filters, or update firmware, you’ll end up searching online forums.
Recommendation for the manufacturer:
For users: Download the manual from the official website (if accessible) and join the AudioChoice Facebook group or Discord – the community has filled in many gaps the manual leaves open.
Since "Audio Choice" is not a widely recognized major brand for professional audio equipment, it is highly likely you are referring to a Theatre Solutions QM4, QTX QM4, or a generic 4-Channel Stereo Amplifier often sold under various brand names (like Adastra or Velleman).
These units are commonly used for multi-room audio or small commercial installations (restaurants, shops).
