How do sounds, amplifiers, preamps, and microphones stand out?


Many people in the audio industry are technicians who have been immersed in it for many years. The pursuit of "good sound" and "good voice" is the goal of their life. But "What is a good sound?" For this problem, even professionals, there are many different understandings and answers. Let's talk about the standard and characteristics of good audio from the following aspects for your reference.

First, what is a good speaker

From the scientific and objective point of view, a good speaker is a speaker with wide frequency response, high sensitivity, high power, balanced curve and phase accuracy. The speaker is matched with the power amplifier and the front stage to maintain the "phase is consistent, the frequency response curve is balanced and natural". When the music is replayed, the subjective listening feeling is bright, clear, soft and true and natural is a good sound (system).

The frequency response of the speaker is strong, the sensitivity is high, it is easy to push, the power is relatively more stable and safe, the curve is balanced, the phase connection is reasonable and appropriate, and it will not be distorted due to energy internal friction, so that it can be reproduced naturally and naturally. A variety of sounds, and the sound has a strong layering, good separation, bright and clear and soft. In addition to being easy to push, the speaker with high sensitivity and high power is more important. The maximum sound pressure level in the stable safe state can be “strengthened”, and the driver can be obtained without much power. Sound pressure level.

In terms of subjective evaluation, people's personality, cultural cultivation, artistic cognition, preference bias and standards are different, which leads people to be different and describe different ways.

Our comprehensive subjective evaluation is: a loud speaker that can be "shocked, but bright and clear without harshness, roundedness, naturalness, and flexibility."

As a private room speaker, you must also add the requirements of "good singing, sing-resistant, durable (can Hi) and strong sense of envelopment."

Second, what is a good amplifier

The standard of good power amplifier is reasonable efficiency, proper damping coefficient, wide frequency response, strong voltage transformation capability, normal balance of output waveform, high signal to noise ratio, low distortion and strong analysis (analysis). When such a power amplifier is matched with a balanced high-quality speaker, the sound that appears is clean, clear, and has good separation, and the listening level is clear.

Of course, the power amplifier works like the voice coil of the speaker, which generates a high temperature, so it must have reasonable circuitry, high-quality components and good heat sink.

With the above conditions and the ability to match the speaker's soft, clear, "transparent" sound quality, and stable work, it is a good amp.

Third, what is a good predecessor

The most important indicators of the good pre-level are the reverberation chip, the op amp, and the circuit. The function is appropriate, reasonable, sufficient, adjustable, and the sound is natural.

Fourth, what is a good microphone

With the speakers, amplifiers, and preamps, the sound is really natural (all the sounds are all) is a good microphone. If it is wireless, it is better to run the U-segment wireless microphone without frequency, constant frequency, anti-shock and shockproof.

The sound that can achieve the above subjective and objective conditions is a good sound. Don't be superstitious about "American", "Japanese" or "British" - the sound is good or not, in fact, the contrast is very simple: while listening to the familiar tracks, take A few words from the microphone, you can know by switching back and forth.

Of course, if you have the professional knowledge and testing equipment, in addition to subjective contrast listening performance, objective scientific test comparison is also a good method. At any time, people's subjective consciousness will inevitably lead to misleading themselves, but objective scientific data will not "cheat."
