"A" osztályú előerősítő MTX Monitor

[tonee73]

S ez mitől A osztályú ?

[Sugden2020]

az elölap széllessége 435mm (nem 19 inch kivitel). a bementi választókon látható átlátszó plaszt védök mögötti feliratok cserélhetöek (van vagy 150 darab különbözö felirat hozzá, pl. CD, TAPE, TUNER, stb)

Eladó tökéletes állapotban a Funk Tonstudio Technik által gyártott MTX MONITOR elöerösítö, 8 bemenetes (4szimetrikus, 4 aszimetrikus) és sok-sok kimenettel plusz mátrik áramkörrel amivel lehetséges a bemeneteket/kimeneteket ide-oda "terelgetni" (akinek sok magnója van, tetszeni fog). Eredeti ára 3,800.- Euró, én odaadom 1,900.- Euroért. Csak szélyes átvétel (Komárom és környéke). Beépített fejhallgató erösítö, brutális müszaki paraméterek:
