The Importance of Tape Monitor Loop

Probably most of today’s manufacturers reject the idea of their product featuring a tape loop. At Moonriver Audio, we have concluded that the tape monitor loop is essential. Not only does it add the option of monitoring the difference between recorded and source material at a real time.

It also, and most importantly, makes possible to insert to the chain -at will- a digital or analog room correction processor, a buffer, a noise reduction system or any other line device available to improve the sound of connected sources.
