9.4.1. Stereo Outputs 1-6 (Mono Outputs 1-6)
The outputs available on the front panel through ¼” stereo jack sockets are push-pull,
designed to drive 150 mW into 32Ω to 600Ω professional headphones. Each output is
individually buffered.
9.4.2. Master Level Control
The master level control will set the maximum level of all channels and will need to be
set high if an unbalanced consumer input level (-10dbu) is used. This level control can
be disabled by setting jumpers within the unit. See Section 11.4.3.1 for details on
removing the equipment covers. The two jumpers JP25 and JP26 can be found near the
volume potentiometer VR1 :

9.4.3. Channel Volume Controls
Each channel has its own volume control so that you have control of the signal volume
to an individual output whether it is from the master input or the override input.
