NP Elektroakustik

[erik_DK]

NP Elektroakustik was a small Danish company making audio solutions for among others DR, the National Danish Broadcast. Quality is at least on par with NTP, Tore Seem and the big famous German manufacturers. NP is often mistaken for NTP, a more well-known Danish company.

Most of the production was customer-specified mixing consoles, made as one-off products or in very small numbers. Getting documentation and manuals is extremely difficult, so please post anything, you may have.

NP IK36 Channel-strip (IK: short for "indgangs kanal" - input channel)

Far from complete, but the essential schematics are here

NP IK42 channel-strip. Schematics and component overlay.
A good example of a channel for a large NP-desk.

It is built on a mainboard with all the knobs and dials. All functions are built as modules on the mainboard. Everything is there. You better print all the files and make your own complete manual.

If you ever come across a full mixer with this input channel, send me a PM. I have lots of files and you might be lucky, that there is something useable for you.

Plus bass - treble control schematic.

Not much, but at least you can see the pinout of the module.

NP channelstrip - unknown.

I don´t know which channelstrip, but the schematics belong together. It is an old one - the mic amp has the NTP M100 DOA instead of the later NP M99.

Far from complete.

NP microphone amp.

Old design running from a 24V power supply. Uses NTP M100 op-amps instead of the later NP M99
