Input Buffer for Hypex NC1200 module (2 units)




We offer our customers a Buffer for the Hypex NC1200 module in kit form, so that the most expert users who already have the Hypex NC1200 power modules, can install them thus improving the sound quality. This Buffer includes SIL994 Enh Ticha operational amplifiers from Sonic Imagery. These operational amplifiers are characterized in that they operate in class A, providing a very warm sound similar to vacuum valves. The buffer card is ready to be able to insert other operational amplifiers, such as Sonic SIL990 or Sparkoslabs SS2590, used in professional audio and recording studios. The JRC MUSE series, AD and OPA series of instrumentation and discrete operational amplifiers can also be used. When carrying a socket, they can be exchanged so that the sound differences between them can be audibly compared. Only dual operational amplifiers (dual amp op) can be inserted into the socket. Also includes Sparkoslabs ULN regulators.


The printed circuit board of the buffer has been developed in such a way that it adapts physically to the NC1200 module of Hypex, mounting in the form of a turret so that it does not take up more physical space inside the amplifier, only a few millimeters of elevation. This board is only valid for the V4 and until V6 of the NC1200 module. See here:  https://atm-audio.com/input-buffer-for-hypex-nc1200/


The use of this kit requires technical knowledge from the user. The equipment where the NC1200 modules are housed must be disassembled and modifications must be made to those modules. This requires a welder to make a welding bridge. This modification is indicated in the NC1200 module service manual that can be downloaded from the Hypex website at this link:




It is also necessary to feed the buffer. To do this you have to locate a point where there is a supply of +/- 12-15V and solder (or connect) the cables to the connector supplied in the kit. If the NC1200 module is powered by the manufacturer’s own supply (SMPS1200) it will be easier because the supply has a connector that provides the power.


This buffer is compatible with the power amplifiers of Theta Digital, March Audio, Apollon Audio, Nord Acoustic and Rouge Audio. Mola Mola uses a physically modified Hypex NC1200 module, so this buffer is not valid.
