Redbox RB-PA2

Michael R. 849, 04.01.2013
Report on Sonifex Redbox RB-PA2
After a long hesitation due to the high purchase price I had decided to buy this preamp because there are only a few with features such as adjustable balanced XLR outputs. The consultation with Sonifex because of the somewhat misleading statement of -3dB at 15kHz in the frequency response (see Sonifex catalog) unfortunately led to no satisfactory answer. So I took the risk and bought the device anyway.
What should I say, the device works flawlessly, sounds very good and precise, no loss of height as first feared, rich basses and the noise voltage spacing at + 12dBu at the output and connected pickup was about -74dB peak and about -82dB RMS Considering that the 115 / 230VAC power supply is integrated in the device).
So with a 50 dB dynamic on the sound carrier (which is quite a plate for a record) is still 25-30dB distance to the noise. Since the background noise on the sound carrier will be rather the problem.
Although Sonifex has refrained from the installation of expensive circuits, the design has been designed very solidly. The components used are of decent quality, everything is on a circuit board, no unnecessary internal cabling. The amplification of the downstream symmetrical amplifier can be adjusted from the outside, up to conventional level values. I tested it with a Technics SL1210 MK2 and MM-Pickup ELAC D768, an MC-buyer, I had unfortunately not to hand, but should function synonymous with it.

The scope of delivery includes a cold-plug mains connection cable, the device and a passport with the serial number. The housing concept may not be optimal for everyone, but if you do not constantly change the pickups, everything has to be adjusted only once. Afterwards, the device can also be mounted on the back of a rack and does not need any further support.

My Conclusion: Recommended for anyone who needs a (two) reliable TA preamp, which is long lasting and works with XLR equipment.
