TDA7293Pro

The TDA7293Pro is meant for professional use in converting passive speakers to active. On board is a Balanced Input with provision for adjusting the sensitivity to dBu or dBV.

The op amp is powered by it's own 7815/7915 voltage regulators. An additional 9V 7809 regulator is assigned to power the Output DC Protect circuitry. If harmful DC is sensed at the output, a 9V relay will disconnect the loudspeaker, thus preventing damage.

The TDA7293Pro power output is 36W into 8Ω and 60W into 4Ω. With this power, this module is suitable to convert 2-way nearfield recording monitors to active.
