On page 22, the manual shows a diagram of how to bridge Zone 1 and Zone 2 to create a single, high-power output for outdoor speakers. This is not intuitive from looking at the back panel alone. Users who skip the manual often assume the QM4 is underpowered when, in reality, they simply haven't activated the bridging sequence (which involves specific Dip-switch combinations listed only in the manual). One of the QM4’s killer features is priority muting (e.g., a page automatically lowers the background music). But the manual clarifies a critical point: The priority is not default. You must configure the VOX (voice-operated exchange) threshold. audio choice qm4 manual better
Whether you are a business owner, a volunteer sound tech, or a professional installer, make the commitment today. Download the official PDF. Read it cover to cover. Mark the pages on gain structure, zone bridging, and priority muting. Then, perform a before-and-after test. You will be astonished at the clarity, power, and reliability your "old" QM4 suddenly possesses. | Feature | Online Forums | Official Manual
