Features of HDR2
9 Groups and 99 Recording Tracks
The HDR2 provides 9 groups, numbered 1-9, and 99 recording tracks for each group, for
either the internal flash memory or SD card. You may select any blank track number you
prefer to record on before you record, or the HDR2 will select a blank track for you
automatically. Whenever a track is recorded, the track number will remain the same, even if
the previous track is deleted or added. All of the internal flash memory or SD card may be
devoted to a single continuous track if desired.
Two Storage Folders
The HDR2 provides two folders for storage of files: in FOLDER 1, you can record music either
from the built-in microphones, from external microphones, from an electric guitar or from Linein sources and play it back. In FOLDER 2, you can download MP3 music from your PC or MAC
and play it. The two folders allow flexibility to organize your recordings and downloads.
Leading and Unique Sound Mixer Technology
The Galaxy Audio HDR2 is equipped with built-in microphones, and two audio inputs. When
you connect audio inputs to record, the sound will automatically be mixed with the built-in
microphone with a balance level. Our unique sound mixing technology is perfect for occasions
with multiple instruments playing, combinations with background music or for the creation of
any creative music made by you!
Multiple Audio Inputs Selection
The HDR2 is equipped with two Audio-in jacks for Left & Right channel recording. A selector
switch allows an external microphone, electric guitar, or Line-in as recording sources, by
changing the switch position of the Audio-in selector. The multiple audio input selection adds
more convenience to your recording experience.

disk represents the SD card memory), and you will find folders of Group 1 – 9 in each
removable disks. The music you have downloaded from the computer to the HDR2 will be
accessible in FOLDER 2, and the track number depends on the sequence in which the files are
transferred. This means that the track number in FOLDER 2 is not fixed and can be changed at
any time if a track is deleted or added. If you want the files to have a fixed track number, you can
store the music in FOLDER 1. To do this, you simply need to change the filenames according
to the following sequence:
a) If you want to download files to FOLDER 1 with a fixed track number, and store
them to the built-in flash memory, change the file name to M_INT_xx (where xx is
the track number you want it to be.)
b) If you want to download files to FOLDER 1 with a fixed track number, and store
them to the SD memory card, change the file name to M_EXT_xx (where xx is the
track number you want it to be.)
The HDR2 may be powered using a USB adaptor. When connecting with the computer, press
