Architecture & Engineering Speci cations
The direct injection module shall provide the functions of transformer isolation, impedance matching and attenuation into a low impedance
active balanced input.
The direct injection module shall provide switchable attenuation from 0 to 30 dB and output the signal into a balanced 600 Ω load.
The direct injection module the shall be able to accept a maximum input level of +40 dBu (with attenuator enabled).
The direct injection module shall include two ¼ " TRS jack sockets and one industry-standard XLR socket, all linked.
The direct injection module shall o er dual impedances, based on input connection - 1 MΩ nominal (¼ " TRS jack sockets) or 20 kΩ (XLR only).
The direct injection module output shall be transformer balanced and isolated, with a source impedance of 75 Ω and capable of driving a 10dBu
signal into a 2 kΩ load.
The direct injection module output connection shall use an industry-standard XLR connector.
The direct injection module shall obtain power from a nominal +48 V phantom supply via the output XLR connector.
The direct injection module shall feature an earth lift switch, which shall be provided to disconnect the input and output grounds.
The direct injection module shall be housed in a custom aluminium extrusion which shall be covered by a protective rubber sleeve, It shall be
106 mm wide x 145 mm deep x 60 mm high (4.2" x 5.76" x 2.3"), with nominal weight 0.8 kg (1.8 lbs).
The direct injection module shall be the KLARK TEKNIK DN100 and no other alternative shall be acceptable.
