My guess is that it has the same features of the ES15. However, I'm not 100% certain.
Sometimes the only way to know is to take a gamble -- buy it and see what happens when it gets a degraded tape signal. That's the way we discovered the functionality of the ES10 units. Our purchase of the ES10 was originally done purely for review purposes, and the unit would have either (1) been kept for home use, or (2) returned to the store for a refund. As it turned out, it ended up an essential tool in the office for 6 or 7 years now.
And then share your findings with others.
