No output when using one of the LINE INPUTS

• Is the power switched on?
• Is the LEVEL set correctly?
• Is the correct input level set on the rear panel? +4dBu: balanced/professional, -10dBV: unbalanced/consumer.

• Is the Key Input switch engaged but nothing is connected to the key input socket?

The COMPRESSOR is not working

• Is the COMP IN switch engaged?
• Is the LEVEL set correctly? If set too low, the signal level may not be high enough to activate the compressor.
• Are the COMPRESSION controls set correctly? If the threshold is too high, the input may not reach the level at which compression starts.

The COMPRESSOR is only working on one channel

• Are both compressor sections’ COMP IN switches engaged?
• Is the LINK COMP switch engaged? If so, only the left channel controls have an effect on the compression settings.
