Eversolo DMP-A8 volume control

I am new to the Eversolo DMP-A8. 
I used a Bluenode for the last 3 years. 
I have a question about volume control. 

I am playing the A8 through my Accuphase E4000.

I am trying to condense the volume to one unit  

Currently when I turn the A8 on it goes to a very low volume and can’t be heard  

I then turn it up to about 8db and then have control thought the Accuphase  

I can also control the volume through my IPad  

I am searching for a way to control the volume through one source  

Looking for owners or former owners of the A8 to help  

Thanks
