A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The typical output power (RMS) per channel into 8 ohms with THD less than 1% is 10 to 100 watts. This is a reference range; the actual value depends on the specific model and application. Always verify with the manufacturer's datasheet.
Relevant standards include IEC 60268-3 for output power, THD, signal-to-noise ratio, input sensitivity, and input impedance; IEC 60268-1 for frequency response; IEC 60068-2-1/2 for temperature testing; and IEC 60529 for ingress protection. These standards are references for verification, not proof of compliance.
Class D amplifiers achieve high efficiency (85-92%) by using switching techniques where output transistors are either fully on or off, minimizing power dissipation. This is in contrast to linear amplifiers that dissipate more heat. Efficiency values are reference ranges and vary by model.
Inputs are typically balanced or unbalanced with an impedance of 10 to 47 kΩ and sensitivity of 0.5 to 1.5 V RMS for rated output. Outputs connect to speakers via terminals. The supply voltage is 9 to 36 V DC. Confirm exact interfaces with the manufacturer.
