First impression with Revox 3500 s/n 016041 and 016091

They were tested after listening to the Sony F-96 omni.


They sounded unnatural with all that bass boost proximity effect and too much treble.


The Pleiades 130Ω,40mH filter was completely unsuitable (extremely bright result) as the mics are 600Ω. So the values have to multiplied by 3?.


Without anything else ie directly to Sony TC-D5 Pro, the sound is big and nice at 12in or more for male singing voice.


They must be tried with the piano.


Signal path:


Male singing voice - Revox M 3500 - Sony TC-D5 Pro - Sennheiser HD580
