Roland M-160 - Channel Section Signal Flow Explanation; Master Section Signal Flow Explanation

1. Channel Section
Input signals are sent to the Headamplifier where the sensitivity
1s adjusted. When signals are fed in, the Peak/Signal Indicator
light green, and when the input signals are too high levels, it
lights red.
The signals level-adjusted at the Headamplifier are processed
at the Channel Fader, then divided into L and R at the Panpot,
then finally reach the Master Section. A part of signals goes
to the AUX Volume without going to the Fader, and the other
signals go to the Effect Volume after the Fader instead of
going to the Panpot.
2. Master Section
a. Return
The signals fed into Returns 1, 2 and 3 are sent to the Buffer
Amplifiers, then to the Master Outputs after level-adjusted at
the Return Volumes. Return 4's input singals also go to the
Buffer Amplifier, then to the Return Valume, divided into L and
R at the Panpot, and finally go to the Master Outputs.
b. Phones Mix In
The signals sent into this jack are processed at the Buffer
Amplifier, mixed with the Main Bus signals, go to the Head-
phone Amplifier, then to the headphone volume, then to the
Headphone Output.
c, Master Output
The signals sent from each Channel are mixed, then level-
adjusted at the master fader, then sent to the Master Outputs.
d. Effect Send
The signals sent from the Effect Volumes of each Channel are
mixed, then level-adjusted at the Effect Send Volume, then
sent to the Effect Sends.
e. AUX Send
The signals that go to the AUX Volume either without or after
going to the Channel Fader are level-adjusted there, mixed,
then level adjusted at the AUX Send Volume, then sent out to
the AUX Send.
f. Bus In
The signals fed through these jacks are directly mixed with
the Effect Send and AUX Send Busses, then sent to Effect
Send and AUX Send Volumes, then finally sent out.
