DN100
The KLARK TEKNIK DN100 Single Channel Active Direct Injection Box is designed to provide an extended dynamic range, lower noise floor and all the world-class audio performance you’d expect from KLARK TEKNIK. The DN100 is built 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.
The DN100 was designed for professional applications where +48 V phantom power is a standard feature on all mixing consoles. Some DI boxes offer both phantom power and 9V battery operation, however the design compromises required to support both power sources means that the audio performance is degraded. Most notably the amount of signal headroom available. The clip point of the DN100 is significantly higher than many professional active DI boxes and can provide +10 dBu into a 2 kΩ load. This higher clipping point means that much higher level input signals can be accommodated without the need for switching in an attenuating pad. Correspondingly the DN100 only requires a single -30 dB pad for use when connecting directly to instrument amplifier outputs.

DN100 Architect's & Engineer's Specification
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 Ω load.
Input connectors shall include two quarter inch jack sockets and one 3-pin XLR socket, all linked. Input impedance shall be 1M Ω (jacks sockets), 20K Ω (XLR only).
The output shall be transformer balanced and isolated, with a source impedance of 150 Ωs, 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 Ω
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.

* The DN100 has been designed to allow use at phantom voltages
less than +48V. The unit will function down to +20V (when used with 6k8 dropping
resistors) but with reduced headroom and dynamic range. All the specifications
above are quoted using standard +48V Phantom power.
