The new KLARK TEKNIK DN100 Direct Injection Box is the natural successor to the long-established LBB100.

A ground-up redesign provides an extended dynamic range, lower noise floor and all the world-class audio performance you'd expect from KLARK TEKNIK. DN100 is also designed to handle the rigours of life on the road: a thick aluminium shell protects the electronics, and this in turn is protected by a tough silicone rubber casing, which is replaceable and available as a spare part.

We've also fitted a Kensington security slot in one of the end panels to allow the unit to be made secure using a Kensington MicroSaver security cable.

Attention to detail - it's what makes a good unit into a great one.



  • The Direct injection module shall provide the functions of transformer isolation, impedance matching and attenuation into a low impedance active balanced input. The module shall be able to accept a maximum input level of at least 30dBu provide switchable attenuation from 0 to 30dB and output the signal into a balanced 600 O load.
  • Input connectors shall include two quarter inch jack sockets and one 3-pin XLR socket, all linked. Input impedance shall be 1M O (jacks sockets), 20K O (XLR only).
  • The output shall be transformer balanced and isolated, with a source impedance of 150 Os, capable of driving a 10dBu signal into a 2k_ load. The output connector shall be a 3-pin XLR socket.
  • An earth lift switch shall be provided to disconnect input and output grounds when required.
  • The unit shall obtain power from a 48V phantom supply.
  • The unit shall achieve or exceed the following specifications:
  • Output noise: -100dBu. 20Hz to 20kHz unweighted, with input terminated by 10k O resistor
  • Distortion (THD+N): < 0.01% @ 1 kHz, +4dBu
  • Frequency response: +0.5/-1dB 20Hz to 20kHz
  • Power consumption: <10mA
  • The Direct Injection Module shall be the KLARK TEKNIK model DN100 and no alternative option is available.
