Ah, you're right Matt. It has a breakout A/V cable from some funky<br>
<br>
pseudo-USB connector.<br>
<br>
<br>
<br>
Apparently no VU meter unfortunately.<br>
<br>
<br>
<br>
Now I just need to amp that from line level to a pair of headphones or a<br>
<br>
meter. Is there anything portable off-the-shelf and _cheap_ that will do<br>
<br>
that, or should I break out the breadboard and the LM386?<br>
