The Solo System (AFL and PFL)
Siena's hierarchical solo system and master AFL/PFL selector
provides the flexibility to monitor signals pre fade (PFL) or post
fade (AFL) quickly and easily.
By default, you will be monitoring channels or outputs in AFL on
the local monitor and headphone outputs when you press a
SOLO switch. To change to PFL monitoring, use the master AFL/PFL selector as described below.
Normally, solo switches intercancel. However, if you press a number of SOLO switches in less than a second, they
will latch on together. This provides a quick way of listening to a number of channels or outputs. For example, to
solo both the left and right sides of a stereo mix bus output. Alternatively, you can force the console solos to always
be additive by enabling the mode. Note: in this mode, solos are prioritised according to the type of input
or output see 'Solo Hierarchy' below for more details.
Note also that the master stereo left and right SOLO switches are both mechanically latching. By selecting these
two switches you can set the default solo state to monitor the stereo master output whenever other solos are
cleared.
Note: If these stereo master SOLO switches are not pressed, and no other solos are active, then no signal will feed
the AFL or PFL busses and you will be monitoring silence.

By default, you will
be monitoring channels or outputs in AFL
on the local monitor and headphone
outputs when you press a SOLO switch.
Press to force all input (input
channels and the stereo direct input)
solos into PFL mode. Press
to force all output (16 mix bus and
stereo master) solos into PFL mode.
Select both switches to force PFL solos
across the console.
Solo Hierarchy
In addition to the master AFL/PFL selector, Siena's hierarchical solo system allows you to quickly switch between
monitoring say an input channel in PFL and a mix bus output in AFL. The local monitor and headphone outputs are
controlled according to the following solo hierarchy:
1. Input channels and the stereo Direct Input solos take highest priority.
2. The 16 mix bus master solos take second priority.
3. The stereo master left and right solos take lowest priority.
To best explain the power of this system, let's take a typical operating scenario. For example, you may wish to set up
the console so that you can PFL any input channel quickly, but still monitor your mix bus auxiliary sends or group
masters in AFL. Select the switch to force all input channel and the stereo direct input solos into PFL
mode. Also check that the switch is not selected so that all output solos remain in AFL. Turn on the
switch to enable additive solo selections. Finally, turn on the stereo master left and right SOLO latching switches
and check that you are now monitoring the stereo master output post fader (in AFL).
Now press any of the 16 mix bus master SOLO switches. Since the mix bus master solos are higher in priority than
the stereo master solos, you will be monitoring only the output of the mix bus (in AFL) even though all three SOLO
switches remain illuminated.
Then select a SOLO switch on any input channel. This time the hierarchical system works to provide you with
monitoring of the input channel only. The input channel is monitored pre fader (in PFL) since this was the selection
made from the master AFL/PFL selector.
If you now e input channel solo, you will go back to monitoring the mix bus output in AFL.
Remember that you can also use at any time to clear down all selections except the stereo master solos.
This allows you to quickly revert to monitoring the stereo master output.
