You can also change the value on the I/V resistors so the output increases.On R34 and R35 on the digital board you have resistors that can change the output.
I myself have decreased the output (sounds better I think)
1.5VRMS 200R
2.0VRMS 300R
2.5VRMS 390R
3.0VRMS 560R
3.5VRMS 750RIf your are using I/V transformers the resistors on the analog board also needs replacement.
If it is possible to change the OPT to 1:10 ratio the output impedance will decrease and matching could be an issue.
