I can't see clearly what's your problem with the channels in 1622. In case you have available a second source, make all the necesary input settings (depends on the input) and slide up the relative fader; the upper you set it, the higher volume you get from this input.
You asked also a user manual. Here is the direct official link for you to download the English version. In case you'd like another just inform me with a post. Note that the model 1622 is an older one; the model that is nowadays equal to 1622 is 1622FX. In two words it's the same model but the FX has also integrated effects.
In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.
