SCA D11 DI Module

SCA D11 DI Module


No longer available as a DIY kit


The Seventh Circle Audio 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. Only available as a fully assembled module.


CH02-SP-D11 subpanel must be ordered separately.


    Switchable Impedance

    Switch between 1M 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.
