Note: Both the main channel INSERT and the COMPRESSOR SIDE-CHAIN
INSERT on the TwinTrak Pro
require the use of a ‘Y’ cable. This is a cable that splits
in two at one end. At the single end should be a stereo TRS jack and at the other end
there should be two mono ‘send’ and ‘return’ jacks. Connections are shown below:
Q. Can I take my TwinTrak Pro with me when I travel internationally?
A. Yes, but the correct fuse and voltage setting must be used in each territory. There is
a voltage selector on the rear panel of the TwinTrak Pro, which also houses the main
fuse. If you are in the UK the voltage selector should be set to 230 V and a 315 mA
fuse should be fitted. If you are in Europe the voltage selector should be set to 220 V
and a 315 mA fuse should be fitted. If you are in North America the voltage selector
should be set to 120 V and a 630 mA fuse should be fitted. If you are in Japan the
voltage selector should be set to 100 V and a 630 mA fuse should be fitted. If you are
in territory other than those mentioned, please look at the above settings and choose
the setting and fuse value appropriate for the local mains voltage.
TROUBLESHOOTING
No LEDs illuminate
•
Is the POWER switched on?
•
Is the correct mains voltage being used for your unit? If not, the fuse may blow,
requiring the correct fuse to be refitted.
No output when using the MIC INPUT
•
Is the power switched on?
•
Is the LINE switch on the front panel switched out?
•
Is the INST switch on the front panel switched out?
•
Is the LEVEL set correctly? (See 'Facilities and Controls' on page 4)
•
For microphones that require phantom power, is the +48V switch engaged? (If
you are unsure whether your microphone requires phantom power, check the
user guide for your microphone.)
No output when using the LINE INPUT
•
Is the power switched on?
•
Is the LINE switch on the front panel switched in?
•
Is the INST switch on the front panel switched out?
•
Is the LEVEL set correctly? (See 'Facilities and Controls' on page 4)
No output when using the INSTRUMENT INPUT
•

The OPTICAL COMPRESSOR is not working
•
Is the compressor section’s IN switch engaged?
•
Is the LEVEL set correctly? If set too low, the signal level may not be high
enough to activate the compressor.
•
Is the COMPRESSION control set correctly? If set too low, the input level may
not reach the threshold at which compression starts.
The OPTICAL COMPRESSOR is only working on the top channel
•
Is the lower channel compressor sections’ IN switch engaged?
•
Is the STEREO LINK switch engaged? If so, only the compression meter on the
top channel displays the gain reduction and only the top channel controls have an
effect on the compression settings. The top channel is called the master, as it
controls both compressors when in stereo mode..
The MID SCOOP EQ is not working
•
Is the EQ section’s IN switch engaged?
•
Is the CUT FREQUENCY control set to a frequency that is present in the
signal?
No wordclock lock
•
Is your external wordclock source transmitting wordclock?
•
Is the sample frequency set to match that of the wordclock-transmitting device?
•
Is an external wordclock cable needed and, if so, is it connected?
No output from the digital output option
•
Is the sample frequency set correctly?
•
Is the receiving device set to receive at 24 bit?
•
Is the receiving device set to external sync?
