|    amplifier input sensitivity    |

      From: alexander.dyszewski@chello.at              Hello,              where is the point in making the input sensitivity of a modern amplifier       as low as 250mv ?       Lets assume the amplifier needs 0,775Vrms (=0dBu) for full output and       most digital sources tend to produce about 2Vrms leaving a 8dB margin       for quieter recordings. I found a Marantz Fmtuner with 1Vrms Output and       i think other tuners will bei similar. This will give only about 2dB       margin, but since most fm broadcasts are modulated noise anyway there       should be no problem in achieving full volume. High quality reel-reel       tapedecks will have balanced XLR connectors giving +4dBu which equals to       1,2Vrms. So again no reason for low input sensitivity. Riaastages might       be different, but i think that a high quality preamplifier should be       able to deliver 0dBu even with strangely mastered records.              Can anybody here think of any (high quality) source that will actually       need such high sensivity ?              sincerly,       Alexander Dyszewski              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
