Hi-Fi Audio Episode 1

안녕하세요. Hi-Fi 오디오에 대한 이야기를 나누게 되어 매우 기쁩니다. Hi-Fi는 높은 충실도를 의미하며, 이는 우리 귀에 들리는 사운드를 왜곡 없이 재현하는 오디오 장비의 특성을 나타냅니다. 많은 분들이 오디오의 복잡함에 대해 고민하실 수 있지만, 이는 개인의 취향에 따라 다르게 접근할 수 있는 흥미로운 분야입니다. 이제 구체적인 방법을 아래에서 확인해보도록 하겠습니다.

Hi-Fi Audio

Hi-Fi is short for High Fidelity. Originally a term in acoustics, it refers to the characteristics of audio equipment that reproduces sound in the human audible range of 20 Hz – 20 kHz faithfully and without distortion.

Hi-Fi System

 

Components	Description
Source Device	CD players, turntables, network players, DACs, etc., are devices that play audio sources
Preamp	Receives signals from the source device, amplifies them, and controls volume and tone
Power Amp	Amplifies the signal received from the preamp to drive the speakers
Integrated Amp	An all-in-one amp that combines the preamp and power amp
Speakers	Bookshelf or floor-standing speakers
Subwoofer	Enhances low frequencies (optional)
Cables and Accessories	Speaker cables, interconnect cables, power cables, etc.
Acoustic Tuning Equipment	Room acoustic panels, bass traps, digital room correction equipment, etc. (optional)

 

Things to Consider When Building a Hi-Fi Audio System

Features

• Generally, only 2-channel stereo for front L and R is used
• The sound heard from the playback device should resonate like the sound in the original environment
• Pursues pure audio sources and minimizes distortion, coloration, and loss through various methods. The system is operated using sound effects, including equalizers, appropriately

Things to Note

• Excessive use of sound effects can easily degrade sound quality
• Space is necessary. The environment for listening to music suited to the speakers is as important as the speakers themselves
• Using micro-measured data of acoustic characteristics, there are many aspects to consider, such as phase distortion, standing waves, and booming

 

Speaker enclosure, audio room, speaker placement, power supply, room acoustics, etc., are all very important. Knowing and enjoying Hi-Fi audio is an astronomical hobby that costs more than any other hobby for adults. The ultimate tech is a house with a listening room.

What You Need to Enjoy Hi-Fi Audio

• A lot of money
• Space, that is, a home
• Time to spare
• Study on Hi-Fi audio

 

I shouldn’t have started with Hi-Fi audio… just kidding. For some, audio might be hard to understand, and they might wonder if it really needs to be that complicated. I think many people have such thoughts. This is a matter of personal preference, and I believe those who use different high-end audio systems would find it cute.

I plan to cover various ways and types to enjoy Hi-Fi audio in detail in a series.
