In professional audio systems, the matching of professional power amplifiers and professional portable music speaker, in addition to the soft timbre (timbre collocation is often said to be soft and hard, it is based on the designer's design and materials for the tone color, and has the characteristics and personality ), there are some hard matches on technical indicators. Soft collocation is based on accumulated experience and personal preference, while hard collocation is determined by data and basic technical common sense. The following is a brief description of the four major "hard collocation" related issues.
Do you know the 4 major combinations of professional audio systems portable music speaker?
Impedance matching
1. When the tube power amplifier (tube amplifier) is matched with portable music speaker, the output impedance of the amplifier should be equal to the impedance of portable music speaker, otherwise it will reduce the output power and increase the distortion. Fortunately, most amplifiers have variable output impedance matching interfaces such as 4-8-16 ohms, and impedance matching with speakers has become simpler.
2. For the matching of transistor power amplifier (stone machine) and portable music speaker impedance
① When portable music speaker impedance is higher than the output impedance of the power amplifier, there is no other effect except for the different degree of reduction of the output power.
② When portable music speaker impedance is lower than the output impedance of the power amplifier, the output power increases proportionally, and the distortion generally does not increase or the increase is negligible. However, portable music speaker impedance cannot be too low during matching, such as as low as 2 ohms (referring to when two 4 ohm portable music speakers are connected in parallel). At this time, only the power amplifier has a large margin, and the high-power tube and multi-tube parallel push-pull with good performance are used. It has no effect on such power amplifiers.
On the contrary, ordinary power amplifiers are generally not rich enough, and the pcm and lcm of the power amplifier tubes are not large. When the volume is turned on again, the distortion will increase significantly, and the box will be destroyed in serious cases. Pay attention.
Power matching
1. In principle, when portable music speaker rated power is inconsistent with the power amplifier's rated power, for the amplifier, its power is only related to portable music speaker impedance, not portable music speaker rated power. Regardless of whether the power of portable music speaker and the power of the amplifier are the same, it has no effect on the work of the amplifier, but is only related to the safety of portable music speaker itself.
2. If portable music speaker impedance meets the matching requirements, and the withstand power is less than the power of the amplifier, the driving power is sufficient, which sounds very comfortable. This is often said that the reserve power of the power amplifier must be large in order to fully express the full content of the music, especially the low frequency part of the music, which is more vivid and powerful. This is a good match.
3. If the rated impedance of portable music speaker is greater than the rated power of the power amplifier, although both can work safely, at this time the power amplifier is not enough to drive the power, and the loudness will be insufficient. It often appears that it has been turned on to a saturated state, and the distortion is aggravated. Powerless. This is a poor match.
Match according to the damping coefficient
For choosing a pair of hi-fi speakers, there should be the best specific resistance requirements (responsible speaker manufacturers should provide this data, which refers to the requirements for the damping coefficient of the power amplifier. To make it clear is to match this. For portable music speakers, what is the damping coefficient of the power amplifier required?).
The matching of wires
The effect of use is a matter of opinion. In general, a good cable will improve a certain system of audio equipment. Its transmission theory is too complicated to say, it can only be briefly described.
The material and structure of the transmission line determine three important parameters, namely resistance, capacitance, inductance (and electromagnetic effect, skin effect, proximity effect, reactance, etc.). Don’t look at the small gaps in these parameters, which will directly affect the audio system frequency. Characteristics, damping characteristics, signal rate, phase accuracy, and tone color orientation and sound field positioning, etc. Its main function is high-speed transmission (to minimize signal loss), anti-vibration, anti-noise, anti-interference (mainly radio wave rf1 radio frequency interference and em1 electromagnetic wave interference, etc.).
