This is about average performance with both the Abex TCD-721R and TCD-726
test discs.
- CD-Check Audio Test Disc
The CD-Check Test Disc is a very useful tool for evaluating the Sound Reproduction
/ Error correction capabilities of a CD player. The disc offers a signal combination
with disc error patterns to rate the drive's reading music abilities
and reproduce it completely. Five tracks on the disc contain a progressively
difficult sequence. These tracks are referred to as Check Level-1 through
Check Level-5.
The
tracks are reproduced (played) through a software multimedia player (i.e.
Winamp, PowerDVD, Windows Media Player). Each level is considered as passed,
if the tone coming out
from the speakers is clear and continuous without interruptions, skipping
or looping. The higher the Check Level passed, the more reliable the sound
reproduction
of the drive.

The drive managed to playback the first three levels of the audio check
disc without problem. The drive played back the three tracks without audible
clicks
while
it found it hard to pass the last two error correction levels. Again, average
performance.
