Product introduce
There are two ways to balance and single-ended conversion: passive conversion, use of audio transformer, the advantage is that there is no need to power on and save trouble, the disadvantage is that the audio transformer can meet the HIFI transmission price is expensive, the general cargo is non-linear for the transmission of the entire frequency band of the audio range; The second method is active switching, using op amps or discrete components (or even tubes), with the disadvantage of balancing signal regeneration or poorly synthesized waveform symmetry.,.
The most ideal is the use of a special conversion IC in this link, which is similar to an op amp, but the difference between the op amp and the op amp is that the chip's internal resistance is laser-engraved, precisely fine-tuned, so that the signal to the hot and cold end is strictly symmetrical: pay attention! ! This is the essence of the balanced circuit: the common mode rejection ratio is high. The advantage of the maximum common mode rejection ratio is that the background is quiet and the reduction of weak signals is high.
Other non-formal conversion methods: use conversion wire, use cold end grounding, etc.: The real balanced amplification line is the independent amplification unit of the cold and heat signals. You put the cold end output grounded, you think about it again. what!
This machine material: pure aluminum wire drawing shell; Texas Instruments special conversion chip, Switzerland Nutrix gold-plated balance seat, gold-plated RCA seat, imported resistance parts.
There are two types of link converters: external power supply and built-in power supply.
A, the external power supply is a single power supply, the DC adapter voltage range is 18--30 volts, 30 volts is best. Use a commercially available DC power adapter, which can meet the voltage of 18--30 volts, plug specification 5.5-2.1 (compatible with 2.5); (the product has built-in single-turn dual-supply circuit, the internal structure picture is not updated). Therefore, using a single power supply of 18-30 volts can work normally, but in order to avoid large dynamic clipping, the store's supporting power supply is 30 volts.
B, built-in power supply, directly plug in 220 volts AC, see the description of the internal structure.
