8v Input headunits using Zapco Studio amps

[Rob. 10+ year member]

Hi there, I just bought a Studio 100 and a Studio 50 amp.

Im using a Clarion DRZ9255 headunit, which is an 8v headunit.

Anyway, I have been on other forums reading that the older Studio amps can only accept up to 2.7v..

Should I be worried of any issues ??

thanks

Parts Express sells in-line attenuators to remedy this.

To add:

I read that the higher 8v headunits are suppose to help the amp by not

turning up the gains that much on the amp which helps reduce possible noise in the system.

I shouldnt see why there would be any compatibility issues with both the amp and the headunit. But then again, the zapco owners manuals states maximum input level spec....

what exactly does this mean in correlation to the headunit input voltage ?

thanks

You mean line level attenuators...

i'd contact Zapco and confirm anything with them. i'm sure if there is a Voltage problem they can recommend something.

Already did:

The Deck most likely only puts out the 8v at full volume. I would measure the output of the headunit to see where it is putting out what output on the volume and keep that in mind when you are playing it. You can keep the gains at a min and just be careful.

Thank You

for me thats one thing i've found strange about my HU. when i checked my voltage out i got a reading of 8v no matter the volume level. i'd say use the drz and just gain down and watch that knob or if you want u could sell it to me //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif for 50 dollars //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Yes, i said in-line because because they are installed "in-line" (between the RCAs and the amp). Figured you knew they were for level attenuation based on the question you asked. I will be more specific next time, i didn't realize you were Canadian.......................

Ive been running both my Z100's and my AG 200 with a 7 volt feed, No issues.

Great. Thanks. How high are your gains set at ?

Btw, your system setup is crazy !

 

[edzy 10+ year member]

My gains are like no more then a 3rd on the z100's, and like 1/4 on the AG.

 

[Rob. 10+ year member]

I dont know what I was thinking !

The DRZ9255 is 4 volt not 8 volt

I must have been confused because it's 8 channel deck...LoL

Disregard this entire thread...
