Nina is quite unique in the world of tube audio gear in that it is a tape head preamp with a JFET & MOSFET cascode input section and using the venerable 6922/E88CC/6DJ8 triode for the output section, and is designed for use with most reel to reel tape decks, consumer or pro.
We understand that some hard core tube aficionados will balk at using silicon components, but our aim is to present the best possible performance and sound, especially with a very high gain preamp such as Nina, so using both transistors and tubes is the best solution for the lowest background noise operation.

The preamp circuit is a hybrid design by renowned tube circuit guru Ray Waters. His brilliant circuit has been mated with our in-house designed regulated solid state power supply.

The result is a fantastic sounding tape head preamp that is able to work with a wide range of playback head impedances. Another unique feature of Ray's design is that Nina can be switched between NAB (7.5 & 15 IPS), IEC 7.5IPS and IEC 15IPS.

Nina can also be supplied without the XLR balanced output, for those who do not require a balanced audio signal. See below for pricing.

Nina is a tape head preamp, so it must be connected directly to the decks playback head, NOT the tape deck audio output!

Nina is housed in a 2U, all metal, rack mounting chassis.
