Incorrect setting
Timecode signal
input
Select Preferences, Timecode Setup, then
Timecode Inputs on TRAKTOR2, then
check that the double circle is displayed
for the channel to which the timecode
signal is input. (The double circle for
V
I
N
YL is displayed somewhat distorted.
The shapes of the double circles for the
outer and inner tracks are different.)
Perform this check only when a timecode
control CD or
V
I
N
YL (media on which
timecodes are recorded) is available.
If no double circle is displayed, possible reasons
are as follows:
1
The channel for USB AUDIO output of the
DJM-
8
50 and that for USB AUDIO input of
TRAKTOR2 do not match.
→
Check the channel setting on the Input
Routing screen in the Preferences window
of TRAKTOR2 and that of the PC Setup
Utility.
2
Connection between the external device
(DJ player, turntable) and the DJM-
8
50 is not
properly
made.
→
Check the connection and check if the RCA
cables are broken.
