Humming along

[mdlbear]

As it turns out, the isolation transformer has some problems -- it gets overloaded with a full-range line out signal. (The technical term is saturated: the transformer's iron core won't transmit any more signal than it takes for it to be fully magnetized. This turns out not to be a whole lot.) So, although it blocks hum like a champ, it's worthless for line out.

Fortunately, my output mixer has a monitor output with a volume control. That appears to cut the output enough to not saturate the isolation transformer.

In other news, some of the older tracks I've been having problems with might be fixable if I apply Audacity's built-in compression tool to each part separately. We'll see. It may work on "RFC1149", "Stuck Here", and "Uncle Ernie's". I've been playing with "Wannabe", which has other problems -- I can do anything I want to the scratch tracks because, well, they're going to get scratched. (Problems include clipping on a most plosives, and a couple of horrendous "clunk"s apparently caused by banging the microphone against the guitar. Oops!)

Fortunately, there's an output I can use. Just ordered a transformer for the other end; different manufacturer but the same basic idea.
