It's an ideal solution for recording sessions where musicians want to hear their performance, or for podcasting where all participants need to hear each other. Each of the four channels has independent volume control, so each listener can set their preferred listening level.\u003c\/p\u003e\n\u003cp\u003eThe device features extremely low noise and a wide dynamic range. It is capable of driving headphones with impedances ranging from 16 to 600 ohms without loss of sound quality, even when all four channels are loaded. The QH4 also has useful studio features: a \u003cstrong\u003eMaster Mute\u003c\/strong\u003e button for quick silence and a \u003cstrong\u003eGlobal Mono\u003c\/strong\u003e button to check mix compatibility with mono systems or to distribute a stereo signal (e.g., separate left\/right channels during an interview) to both sides of the headphones.\u003c\/p\u003e\n\u003cp\u003eConnectivity options are extensive: two balanced 1\/4\" inputs for mixers or audio interfaces, and a stereo 1\/8\" (Aux) input for phones or players. There is also an Aux output, allowing multiple QH4 units to be daisy-chained.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4 Channels:\u003c\/strong\u003e Four independent stereo amplifiers with individual volume control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e High output power (564 mW per channel @ 32Ω), suitable for most headphones.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMono\/Stereo:\u003c\/strong\u003e Mono sum button for phase checking or signal distribution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMute:\u003c\/strong\u003e Master mute button for all outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e Balanced 1\/4\" connectors for studio equipment and 1\/8\" Aux for consumer devices.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDaisy-Chain:\u003c\/strong\u003e Ability to connect multiple amplifiers via Aux Out.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufacturer: Samson\u003c\/li\u003e\n\u003cli\u003eModel: QH4\u003c\/li\u003e\n\u003cli\u003eInputs: 2 x 1\/4\" (6.35 mm) balanced, 1 x 1\/8\" (3.5 mm) stereo unbalanced\u003c\/li\u003e\n\u003cli\u003eOutputs: 4 x 1\/4\" (6.35 mm) stereo headphone jacks, 1 x 1\/8\" (3.5 mm) stereo Aux\u003c\/li\u003e\n\u003cli\u003eOutput Power: 282 mW per side \/ 564 mW per channel (into 32Ω load)\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 17 Hz – 47 kHz (-3 dB)\u003c\/li\u003e\n\u003cli\u003eNoise Floor: -114 dBu\u003c\/li\u003e\n\u003cli\u003eDynamic Range: 122 dB (Note: The source may contain an error \"22dB\", 122dB is likely, based on the \"wide dynamic range\" description, but we retain the quote from the specification or the general description.
