Xlr fully balanced to xlr not fully balanced


Hello,
The output voltage of my dac is 2.3 volts single ended and 4.6 volts xlr. The xlr connectors at the integrated amp are not fully balanced. The question is, what voltage is being utilized at the integrated amp via xlr connector?  2.3 or 4.6? Thanks in advance for any and all help.
