Topic: ADI-2 Pro FS R XLR voltage output level table

I have found a table in the manual, chapter 34.24, a small table on Fixed output level that says:

Volt     dBu     dBV      Ref level   Volume
4V       +14.2   +12    +19 dBu    -4.5 dB
2V       +8.2     +6      +13 dBu    -4.5 dB
1V       +2.2      0       +4 dBu      -2.5 dB
0.775V   0       -2.2     +4 dBu      -4   dB
0.5V     -3.8     -6       +4 dBu      -9   dB
0.315V  -7.8    -10.     +4 dBu     -12  dB

I wonder, since in the Hifi chapter, does this table represent the RCA out voltages? I could not find the level match between the RCA outs and the XLR balanced outs so quick. Can anyone help me translate this table (if needed) to the voltages XLR balanced outs?

(my ref, I want to set the XLR balanced outs to a max output of 3V)

Re: ADI-2 Pro FS R XLR voltage output level table

3 V = 11.75 dBu.

ADI-2 Pro:
XLR and 6.3 mm Jack output on ADI-2 Pro carry the same level up to +19 dBu.
For 3 V use Reference Level +13 dBu and Volume -1 dB.

ADI-2 DAC:
XLR is 6 dB hotter than RCA and the nominal Reference Level.
For XLR 3 V: use Reference Level +7 dBu and Volume -1 dB.

In the manual the last column is dB, not V.

Re: ADI-2 Pro FS R XLR voltage output level table

corrected in the 1st post. It may be worthwhile to mention in the manual the statement KaiS wrote above = that ADI2 pro fs r carries the same voltage on both the RCA and XLR outputs.
