Clarion DRZ9255 & Zapco Studio amps
I called Clarion and they said that the zapco studio may not accept the 8V line out from the drz9255.
Someone on the DIYMA forums also told me that it creates noise.
I read this on the owners manual of the studio 500

Does that mean it can only handle a 5v line out ?

Already did..
I contacted Robert Rugani at zapco..
This is what he says about the studio series amps and also the compatibility with the drz9255 via emails:
Those amps and the Z series we are just starting to see come in for repair with leaky caps. So you may want to be aware of that. Other than that they are great little amps and would do fine for a small system
Should be fine. The Studio amps need to have a singnal ref ground from the head unit to the amp.
Your head unit is not putting out 8 volts all the time. It is probably only putting out 8 volts with the volume turned all the way up. Yes the maximum voltage input on the studio is 5v. Your listening level will be well within range of the output voltage you will actually be getting.
The guy on DIY that told you it would create noise I am not sure what he is talking about. Either you misunderstood him or he does not know what he is talking about. You should not have a noise problem with running a high voltage into an amplifier. If anything your noise floor will be lower. The amplifier, any amplifier, is the nosiest part of the system. The idea of running higher voltage in allows you to run the gain on the amp lower which in turn give you the cleanest signal possible
If you are really worried about it measure the output voltage of your 9255. See what the voltage output actually is and at what point it is putting out the 5 volts. If nothing else you will know that is your maximum input to the amplifier is at. Unless the amplifier has problems already the only thing that will happen is you will overdrive the input cause the input of the amplifier to clip. Overdriving the input of the amp will not damage it…..unless there is already something wrong with it.

line output level with cd 1 khz
Vol 0 dB = 4v
Vol +6 = 8V (Max)
There is your answer - It's compatible! If you don't go past 0 but that's on a 1khz tone. If you're like me, I listen to music. Music is NOT consistent in amplitude. So I wouldn't worry about it.
