Additional Details:
NOTE: This unit will only record .WAV files. However, you can download a .mp3 file converter called GoldWave v.5

It is a very easy to use. Just open the sound file in this program, and save it as .WAV, and select PCM unsigned, 8 bit, mono in the Attributes section.

IMPORTANT NOTE: Use PWM DIRECT DRIVE in the software for this unit (DO NOT USE DAC for Ext.AMP like for the USB5M).

In Windows Vista/ Win 7 the PM66 software must be run as administrator by right clicking on the PM66 icon ad then click to "Run as administrator"

NOTE: To adjust volume, use GOLDWAVE for a softer or louder recording.
