A variable level output control and the ability to handle line, musical instrument pickup, dynamic mike AND phono input signals makes this little item very handy indeed. This is an excellent front end for sound reinforcement applications that don't require the complexity of a mixer but that may require handling varying source and output level requirements from job to job. DJs and roadies in a pinch will benefit from having one of these in their tool box to take the place of larger, more expensive equipment . The rear-panel attenuator switch allows use with higher level line sources such as tape, CD or TV audio. With the addition of this feature, the TC-740A becomes the ultimate Swiss knife of preamps.


(Note that the TC-740A is a custom model made for Phonopreamps.com,

and comes  packed in a standard TC-740 gift box...)
