Optical Output has Low Volume

dudu0101

I'm using the optical output into my DSP amplifier but the max volume is a bit low.

When I use my phone with the app, USB Audio Player Pro (UAPP) with a digital connection to optical into my DSP amplifier, the volume can go much higher.

How can I increase the volume of the optical output?

Edit .. solved .. in Tidal app, the "Normalize Volume" setting was enabled by default which was reducing the volume. Much louder with that setting disabled.

I am contemplating to add a DSP to the setup. How many audio channels is sent by Dudu7 via optical/coaxial? Is it 5.1, 4.1 or just 2 channels?
Thanks in advance.

I just happened to install my new DUDU7 yesterday in my car and On the optical out to Optical in to my dsp, Yes, even I felt the volume to be lower.
Optical has only 2 channel. Left and the right, that is it.

What DSP are you running? I have the JL Audio VX1000/5i and a DuDu 7 waiting to be installed. Were you able to adjust it louder? I plan on using the optical output as well. Do you audibly notice a difference between RCA and optical? Does one sound clearer than the other?

I am running ZAPCO ST 6X DSP. It only has OPT in and yeah the volume is a bit lower. I am still very new to DUDU. I can say it's just been less than 24 hrs I have started exploring DUDU. For now, I am planning to stick around with OPTICAL out. Try tuning and some workaround then I think I may consider USB to DAC to DSP.

Not used RCA and not intending to. So left it open as is. Did not pull any RCAs back to my boot where my DSP AMP is.
