Audio Choice Qm4 Manual 🌟

For those without the original Audio Choice QM4 manual, follow these steps to get started:

Connect Speakers: Use standard speaker cables to connect the outputs on the rear of the QM4 head to your passive speakers (often paired with two 10" enclosures).

Zero the Mixer: Before powering on, turn all channel Gain and Master Level controls to their minimum positions to avoid sudden loud noises.

Input Connection: Plug microphones into the XLR ports or instruments/line-level sources (like a phone or laptop) into the 1/4" ports.

Power On: Switch the unit on and slowly raise the Master Level, followed by the individual channel Gain until the desired volume is reached.

EQ Adjustment: Use the 3-band EQ in the master section to shape the overall sound and the individual channel Tone knobs for specific sources. Troubleshooting Tips Note: If your physical QM4 has different buttons,

No Sound: Ensure the Master Level is up and the correct input is selected. Check that speaker cables are fully seated.

Distortion: If you hear clipping or "fuzzy" sound, reduce the Gain on the specific channel or lower the Master Level immediately to prevent speaker damage.

Silent Background: The QM4 is noted for being remarkably silent when no audio is playing; if you hear excessive humming, check for faulty cables or ground loop issues.

The QM4 is a "4-in, 4-out" matrix mixer amplifier. Its core function is to accept audio signals from various sources (microphones, music players) and route them to different speaker zones with individual volume and tone control. It is typically housed in a standard 1U rack-mountable chassis.

This is the most critical part to understand.

  • Configuration: You can usually run the unit in 4-Channel Mode (4 separate rooms) or Stereo/Bridge Mode (2 channels with higher power), depending on the specific switches on the back.
