You could be right.

DAC2 has four different output level, adjusted by a rotary switch on back panel.

DC coupled, short circuit proofed output circuitry, Output impedance: 50 Ohm
+17 dBu (5.48Vrms) with a 0dBFS sinewave input
+11 dBu (2.74Vrms) with a 0dBFS sinewave input
+7.2 dBu (1.78Vrms) with a 0dBFS sinewave input
+4.8 dBu (1.35Vrms) with a 0dBFS sinewave input

I believe I am using +4.8dBu, can double check.

Looks SPL has max input level of 21.3dBu, how do I understand this? if set to -10dBu, which one should be the max input level?
