D11 Direct Input Module
The SCA D11 is a two-channel active DI that accepts a high-impedance, unbalanced, instrument-level input and produces a low-impedance, balanced, mic-level output. An optional Jensen or Cinemag transformer can be fitted to provide a fully floating isolated output if required. The D11 has a small number of components, requires no adjustment or trimming, and is very easy to assemble.
Features| Switchable Impedance | Switch between 2.2M ohms, 100K ohms, or 10K ohms input impedance depending on your pickups. Other impedances possible with simple resistor substitution. |
| Linkable Inputs | The input jacks can be jumpered so that either input can drive both outputs. This makes it easy to drive a pair of preamps simultaneously. The jacks can also be jumpered in parallel for direct pass-through to an amp. |
| Extremely Wide Bandwidth | Flat response to beyond 200 KHz is guaranteed to keep all the highs intact. |
| High Current Class-A Design | The simple, 3-transistor, all-discrete, class-A circuit has a low-noise JFET input and a fully balanced output. |
| Neutrik Connectors | High quality PC mount connectors eliminate cabling and ease assembly. |
| Optional Output Transformer | Fit an optional Jensen or Cinemag transformer to one or both channels for a fully balanced isolated output. |
| Flexible Power Supply | On-board voltage regulators accommodate power supplies from +/-27VDC to +/-35VDC. Local regulation also keeps inter-channel crosstalk extremely low when multiple modules share the same power supply. |
