하만카돈 스피커 diy version 2

하만카돈 스피커 diy version 2 

하만카돈을 이용한 블루투스 스피커 제작이 꽤 흥미가 있어 두번째 버젼을 아래와 같이 정리합니다. 

첫 하만카톤 스피커를 만들고 나서 유투브와 블로그를 통해 오디오에 대한 몇가지 지식과 정보를 알게되었다.  
pcfi의 기본 구성시 aux cable등 몇가지 아날로그 케이블을 통해 디지탈 신호가 제대로 전달되지 않아  
pc의 디지탈 음원조차 고압축된 mp3라서 음원자체의 손실이 큽니다. 

  
압축이 덜된 aac나 flac같은 고음질 음원(파일)이 더 좋다라는 것을 재인지 하였습니다.   
사실 이전부터 알고는 있었지만 저는 워낙 막귀라 이게 무슨차이가 있을까  
일반인한테 별차이가 없을꺼야 이런생각이었죠. 

제대로 된 고음질 음원이 있다하더라도 pc안의 저가 사운드 카드는 이런 음원을 제대로 재생 전달하지 못한다. 따라서  
제대로된 사운드카드(dac) 가 있어야 한다.

BT로 사운드카드를 통하지 않고 전달하는 것으로 일단 만족했습니다. 

유투브검색을 계속하다보니 알고리즘에 진공관앰프가  계속 나와서 검색해보니 생각보다

싼 가격의 진공관 앰프가 많다는 것을 알게되었습니다.   
그래서 케이스가 있는 것중에 판매량이 많고 가격이 가장 싼 것을 골랐습니다.   
그런데 이게 단독 amp가 아닌 프리앰프이고 bt를 지원하지 않네요.

 진공관 앰프는 대부분 아닐로그 회로라서  
저가제품에는 bt연결이 없는 것 같아 보인다. 결론적으로 2개의 앰프가 필요합니다. 

YS-T50L  
diy 저가 조립형 중에 최고의 가성비를보이고 음질도 나쁘지 않네요.   
aux, bt connecton, volume treble , bass , ys app으로 이퀄라이질 조절이 가능하다. 3$로 이런게 모두 가능한 제품이 있다는게  
기술의 진보와 함께 중국 제조의 힘이 느껴집니다. 

 

구성은 아래와 같다  
PC / aux audio - type c / 3.5 to 2 RCA / 6a2 tube preamp,/ RCA cable/ YS-T50L / harman cardon L,R spk  
케이블2종 6000원  
프리앰프 25000원  
앰프 6000원  
스피커 6000원  
대략 33000원의 비용이 들었네요. 

스프커의 배치에 따라 소리가 엄청나게 달라진다는 것을 알고나니 작은 통에 작은 스피커 두개를 구격 넣는게 왠지 미안한 느낌 이번에는 분리형으로 제작하였습니다. 

프리앰프는 제 차량의 aux입력이 차량이 구형이라 적절한 볼륨으로 들으려면 거의 max두어야 합니다. 

유투브에서 저가형 진공괌 프리앰프를 차량에 설치하여 aux단자전에 설치하는 것을 보고 저도 이를 참조하여 구입했죠. 

우선 실험을 위해 컴에 연결했을때 확실히 프리앰프가 없을때 보다 음질이 더 품성하고 볼륨감이 느껴진다고 해야 하나

표현하기가 쉽지 않은데 .. 더 좋습니다. 확실히 차이가 납니다. 

차량은 우선 보류하고 프리앰프를 컴 옆에 설치하여 2차 스피커를 완료했어요.
