Impedance Matching Transformers

DB228 Wall Direct Interface The DB228 Wall Direct Interface is an ideal impedance matching device for connecting any unbalanced stereo signal to a balanced system. Consumer audio equipment such as CD players, DVD players, MP3 players, phone, etc., may be...

DB14 A/V Presenter The DB14b is a special purpose direct box for applications where a stereo source signal can be separated, and individual volume controls used for each track. It provides a summed XLR output four uses such as an AV presentation from a...

The Shure A95UF is a reversible transformer that matches low-impedance microphones to high-impedance inputs or high-impedance microphones to low-impedance inputs. The transformer permits use of very long microphone cables with either low-impedance or...

The Shure A85F is a low- to high-impedance microphone-matching transformer that provides 24 dB of signal increase gain. It has balanced female XLR and unbalanced high impedance male 1/4'' phone plug connectors, and may be used in reverse. The A85F is...

The Shure A15BT Bridging Transformer can be used to connect balanced and unbalanced devices having different signal levels or impedances. Depending on the configuration, the A15BT provides a minor increase or decrease in signal level. The A15BT can be...

This adaptor is designed to match 50K output impedance to 200R input impedance. It is ideal for connecting a hi-Z instrument to a microphone input. Features Maximizes signal fidelity when using impedance mismatched gear Minimizes high frequency and...
