Bypassing DSP in "digital" amps?




I wonder if it is possible to totally bypass DSP in amps IPD 2400 and FP10000Q (and possibly some others similar)?


I suppose it must be but best to check anyways ... .


Best regards


PS. At present I use analogue signal processing of various D/A-processed digital source signals so I don't want to A/D 

and D/A these signals one more time ... .
