At your risk.
It is simple and minimal.
It uses just 3 pieces of equipment.
1 An Uher 4200 report stereo reel to reel tape recorder.
2 A JVC Nivico 70's radio fed from Uher and feeding the monitoring speaker.
3 The monitoring speaker is a Pleiades made of linoleum sheet Auratone 5C type fullrange speaker with a Tesla drive unit. The speaker wrapped by a net hangs from the ceiling and is currently at about 1 meter and half from floor.
The studio setup is battery powered. It is semi portable.
The JVC radio used as a bass boost amplifier to compliment the small speaker has the added advantage of immediate listening to FM radio just by disconnecting the AUX in mini jack fed by UHER.
Currently commercial radio stations with well known pop songs sound great with balanced frequency response or amazing sound.
Currently almost everything recorded to Uher from CD sounds great through the JVC and monitoring speaker.
Currently almost everything recorded with a microphone connected to Uher sounds bad. Like singing to a broken bathtub while inside a plastic bucket.
But this is the point. It forces one to make any change needed so that the result sounds towards an excellent commercial recording.
Today while trying to record a melody phrase with male voice, the most natural or professional sounding recording is one made with an Electro - Voice 635a omnidirectional microphone at 45o at 2-3 inch connected to a Pleiades (130Ω,40mH) gentle slope low cut filter. This filter is used for reducing bass, mid heaviness to listener's brain due to equal loudness curves (Fletcher, Munson curves) and due to voice effort curves (a softer singing voice produces more bass and treble than a loud singing by the same singer).[Lowe, Morgan]
Connecting the Pleiades V6 1H4 mic booster front end amplifier created a bad sound full of every ambient detail from yards away and at the same time distortion at sibilant sounds. This indicates clipping distortion at some transistor stage of the Uher.
The Fostex M80RP sounded more airy but with above distortion as it has been only connected so far to the Pleiades V6 feeding the mic input of the Uher. Similarly for Shure SM59 which less bright than the M80RP. Ambient sounds from far away could be recorded even with the excellent but low output SM59.
The expensive AKG MI 201-100 omni direction mic gave bass and mid bass and mid heaviness directly connected to Uher, possibly due to,above reasons.
More investigation needed.
A way to go is trying low turn ratio (1:2 etc) input signal transformers with the Uher 4200 report.
Next day addition: the 1/4in was replayed today. The most natural sounding and more treble extended is the recording made with Fostex M80RP - Pleiades (130Ω,40mH) - Pleiades V6 1H4 but there is the s clipping problems.
Later addition 20090216:
Other way to go is connecting the Pleiades V6 CV2269 low gain electron tube mic booster amplifier with a low inductance output transformer for reducing bass heaviness to listener's brain.
