What should I do if the 19 kHz frequency is out-of-tolerance on my Orban Processor?
First verify that a problem really exists by using a second frequency-measuring device and/or verifying the problem with a monitoring service. If the problem is real, contact Orban Customer Service for a crystal replacement; there is no frequency trim available.
Why won't the L–R (stereo difference channel) null with a monophonic input on my Orban 5500 Processor?
Relative phase shifts between the left and right channels prior to the 5500’s input will cause innocuous linear crosstalk between the stereo main and subchannels.
Why does the audio mute when switching between UL and Non-UL presets on my Orban Processor?
This is normal. It occurs because the DSP code must be reloaded.
