Octatrack's output -10 or +4?

Hi all

Can anyone tell me if the outputs on Octatrack is -10 or +4?

I heard somewhere that balanced outputs (which I think OT’s main outputs are – maybe also the Cue outputs) always are +4 and unbalanced are -10. But maybe someone with better knowledge could teach me?

From the manual


Impedance balanced audio outputs:
Headphones out level: +15 dBu
Main/cue outputs level: +10 dBu
Output impedance: 560␣ ␣ ␣unbalanced S/N ratio: 102 dBFS (20-20.000 Hz)
Unbalanced audio inputs: Input level: +8 dBu maximum Audio input impedance: 9 k␣ SNR inputs: 99 dBFS (20-20.000 Hz)
