Matching Transformer

Audio transformer 10:1 for microphone signals

• Unshielded version with print connections
• Wideband version
• Change from unbalanced to balanced and vice versa
• Galvanic isolation to avoid/eliminate hum loops
• Max. input voltage: 5V (1% THD/40Hz)

When installing unshielded transformers into units with interference fields (e.g. power transformers), attention has to be paid to respective shielding measures.
