마란츠 2252B 리시버 입니다.(ending)

마란츠 2252B 리시버 엠프입니다. 상급 버전의 2325,2330,2285 등 리시버들이 귀했을 시절에

가격대비 성능이 좋아 매니아 층에서 상당히 많이 사용됐던 명기 리시버 입니다. 출력에
 
비하여 밀도감 있는 음색과 뛰어난 뎀핑능력을 보여주는 리시버로 보셔도 될듯하며 사진과

같이 상태는 내/외관 생활감 약간씩 있지만 양호하며. 내부역시 많은 비용줘서 제대로

오버홀 받은 제품입니다. 오리지널 마란츠 각인 켄TR 4구 그대로 박혀 있습니다.

전원220v 이며 FM스테레오 및 분리 아주좋습니다  체널당52w+52w 의 출력이지만 그보다

더 높은 리시버류 보다  뎀핑능력이 뛰어납니다. 사이즈도 적당하고 보기에도 화사한 매혹

적인 불빛이 일품입니다.
