The Isenberg Audio Phono 845 phono stage provides amplification for very low output phono cartridges (MC - 0.3 mv maximum output).
It was originally built to give the Jan Allaerts model MC2 Finish and model MC2 Formula 1 cartridges the environment for the best possible working condition.
Recommended by Jan Allaerts himself, the signal paths are designed to the requirements of the JA MC2 Formula 1which certainly includes the JA MC2 Finish. This no-compromise design is made for MC cartridges only and it has no frills like dip switches, for example. Everything is tight and fixed. The cases are like armour plates.
Electronic-wise, the Phono 845 is consequently a dual mono design. Each channel has a 4-step work up for the current-supply. The amplifying section has double shielding made of steel and mu-metal. The signal noise ratio is extremely high. Power supply is separate.
XLR and RCA outputs can be used simultaneously. Every unit is handmade, as well as the assembly and the wiring.

Η γνώμη του J.Allaerts.
Recently we have had the opportunity to listen to the Isenberg Audio phonostage phono845 through our test equipment with our MC2 Formula 1 cartridge.
Right from the start we where amazed with the cool temper and with the natual accuracy of instruments. The space and depth - just unprecedented.
After two hours of listening with phono845, which is particularly designed for MC2 finish gold and MC2 F1, the units are showing even more of their abilities. Having the stage connected to the mains for a longer period of time we will only say that this is the best and quietest phono listening we came across so far. No noise, no impurity or such. A complete presentation and all this with and amplification of 70 dB on RCA outputs and even 6 dB more on XLR.
We must give congratulations to Uwe Schmiedel. His development has managed to find compatibility for our MC2 finish gold and F1 cartridges. Not an easy thing to archive... And we have to say that this small-quantity product is a beauty to look at, as well.
J.Allaerts.
