Switch Protection - Solid State Logic SL 9000 J Series Operator's Manual

The Mix System

Switch Protection

As with faders (see Page 5-55), automated switches also have their own set of
protection modes. When you first start mixing, it's a good idea to set all the switches
to Protected Manual (see below), so that as you intuitively switch EQs in/out, Aux
Sends on/off etc, you do not write these switch actions to the mix. Remember,
however, that Channel Cuts and Group Cuts/Solos are also automated, and you may
not wish to protect the Channel Cuts for example, in the early stages of the mix. As the
mix progresses, groups of switches or single objects can be taken out of the protection
mode as and when you wish to automate them.
To access the switch protection facilities, press the SWITCH PROT button on the front
panel or select Switch Protection from the MIX-DESK/Automation menu, and the
pop-up shown opposite will appear.
The Display All function enables you to check current protection settings for the
whole console. If you believe that objects have already been selected to one of the two
protection modes, use Display All to determine which modes have been used on
which objects. If this is the first time you have used Switch Protection, use Display All
to give yourself an illuminated demo while you check that all the object lamps/LEDs
are working!
With Automated selected in the box in the top centre of the pop-up, stabbing on
Display All will light the lamps/LEDs of all objects currently selected to Automated
mode. If you stab on the grey box, you can toggle the entire console through the three
available modes – Automated (unprotected), Protected Manual, and Protected
Replay. With the channels' Match (M) buttons lit, any object whose LED/lamp is lit
will be in Protected Manual, ie. any changes to the switch state will be heard on
monitor but will not be written to the mix. With the Play (P) buttons lit, any object
whose LED/lamp is lit will be in Protected Replay, ie. changes to the switch state will
be neither heard nor written to the mix (see Page 5-35 for more on Switch
Automation).
There are three basic ways to select objects to a protected mode. Set Multiple should
be used where you need to set up a large number of objects, for example, all the Aux
On/Off switches at the start of a mix. Set Random can be used to set up a small but
varied number of objects within easy reach. Set Single is useful where you need to
select a single object at the far end of the console and don't want to leave your seat!
