Trim
A method of updating fader data is to Trim the previous Mix Pass data. Trim mode originates from VCA (non-moving
fader) automation systems and uses the fader to add or subtract level from the existing moves. It achieved this by setting
up a ‘null’ fader position and then any subsequent moves trim the existing data by the amount of positive or negative
change from the null point. Trim is useful, for example, when you have a complex automated vocal line which needs raising
by 2dB. Rather than trying to re-write the complex moves, simply rollback, hit Trim and move the fader by +2dB. Locate
to the end of the vocal line that needs this level increase, and press the End soft key to commit the trim to a Mix Pass.
The Trim mode is enabled by pressing the Trim key. Once active, faders can write in Trim, at anytime except during the
first pass of a new mix, during Mix Running or in Mix Review. Trim is indicated by the green status LED next to the fader.
When Trim is available at the start of the Mix, the FSM key will toggle all faders between Replay and Trim.
Trim can be used with the fader motors On or Off. If the motors are On, the null point will be the fader position prior
to selecting the trim auto switch or touching the fader. If the motors are Off, the fader can be positioned at a suitable
reference point on the scale before entering the Trim update status by pressing the fader switch. SSL’s automation features
an ‘auto-nulling’ feature so that each time Trim is re-enabled a new null point is set. When writing a Trim move, the dB
trim value is displayed in the scribble strip above the fader.
Both Autotakeover and Snap functions (see below) used in conjunction with a Trim update allows a seamless or smooth
return to the stored mix data.
When Join is used with faders in Trim at the Rollback point, any Trim offset will be retained and written from the point
that the Join key is operated. Revise returns any fader in Trim at the Rollback point back to write but with a new null
point to avoid a level jump.
Move the fader up or down to the new value and all the
existing moves will be copied exactly at the new level.
