Who knows closely with analog and digital recording and that every element of the audio path can be easily overloaded by non standart levels.
CD like any other source must comply with the standard levels. not +8 +10 ets. Only by dBu or dBv scale.
Very good source for all

The most common (quasi - but nonofficial standard) CD player output level is 2 V.
2 V = +8.2 dBu = +6 dBV.
This is all the same level, just other units to express it.
It‘s very easy with AD-2 to dial every level you want, based on Reference Level and Volume Control.
Then there is the option to lock volume.
It‘s even in the manual page 99:
“For example when the analog output should operate like a typical HiFi unit @ 2 V output level (equals +8 dBu), set the hardware Ref Level to +13 dBu and Volume to -4.5 dB.
