Please be very cautious when connecting the CT101 to your audio equipment. CT101 is an active module, and in case of wrong connections or in case of failures, there is a risk of getting up to 14-15V DC offset on the output of CT101. High levels of DC offset may cause damages to power amplifiers, loudspeakers or any other connected equipment. Special attention is required when using DC-coupled power amplifiers.
Before connecting the outputs of CT101, make sure of proper operation and check the DC-voltage at the CT101 outputs. The DC voltage should be no more than a few mVs. In case of any doubt, use a coupling capacitor in series with the CT101 output.
