Troubleshooting
If the unit doesn't power up:
• Check the blue LED on the external power supply. If this LED is on, the problem is further down the line. If
this LED is off, contact us for a replacement power supply.
• Check the connection between the I/O board and drawer. Make sure the drawer is completely inserted and
that the thumb screws are screwed in. Power is passed to the audio circuitry through the two sets of large
connectors CON1 and CON2.
• Make sure the

If there's no audio at the output:

• Similarly, make sure you are plugged into the correct input jacks for the input type.

• Check the output jacks. Note that if there is a cable plugged into the TRS output jack, the XLR output will be
muted.
• Make sure no empty Colour slots are engaged. If there is no Colour in a slot, engaging that slot will mute
the signal.
If there's excessive distortion:
• Make sure you are connected to the correct input. Connecting a line output to the
clip the signal.
• Check your input levels. It's easy to accidentally overdrive analog gear when connecting it to a digital
interface. DAWs use the dBFS scale, where 0dB is the absolute highest level the software can reproduce.
Analog pro audio gear, on the other hand, is calibrated to +4dBu. Unfortunately, there is no standard
conversion between dBFS and dBu, but it's common for 0dBFS to be as high as +24dBu. This means that if
you are sending an average level of -6dBFS from your DAW, the Colour Duo is seeing a whopping +18dBu
at the input. This level will create significant distortion in most Colour modules, and does not leave much
room to turn the Colour knobs without clipping. So, when in doubt, turn down the level coming out of your
DAW a bit.
