Front Panel
VOLUME
This pot controls the level of the front- and rear-panel headphone outputs.
MONO
This switch converts the signal at the headphone and line outputs into a mono
signal. The MONO switch should be activated when mono processors are
connected or when microphones are used as a signal source (see above).
With the MONO function, it is also very easy to check for mono compatibility
of stereo effects.
PHONES OUT
This connector allows you to connect standard stereo headphones. When
using two sets of headphones (via the front- and rear-panel connectors), both
sets should ideally have the same impedance. Otherwise, they could vary
greatly in volume.
POWER-Schalter
You guessed it: this switch turns the Router on and off. The LED illuminates
when power is on.
