Signal optimisers: DI boxes

DI Boxes For an optimum signal transmission from musical instruments to a mixer or amplifier. By using a transformer coupling, interferences due to matching problems, e.g. hum loops, are prevented to a large extent. Input and output are galvanically isolated. For adapting line levels, please use units of the LTR series!

DI transformer 10:1
 

• 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: 5 V (1 % THD/40 Hz)

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