Ganged 
Operation
The UAD Studer A800 implements a control ganging feature that allows easy 
simultaneous parameter modification for all instances of the plug-in. The fea-
ture enables the DAW to emulate the multitrack tape deck scenario more ac-
curately, where a single change to some multitrack machine parameters (such 
as tape speed, formula, and calibration settings) would affect all tape chan-
nels. See “Gang Controls” on page 551 for details.
Mono/Stereo 
Operation
The UAD Studer A800 is designed with a single-channel interface, to emulate 
the individual channels of a multitrack tape recorder. However, when the 
plug-in is used on a stereo track, the “mono” controls affect both channels of 
the stereo signal identically.
Primary Controls
Path Select The Path Select buttons specify which of 
the four possible signal paths is active 
in the A800. The active mode is indi-
cated by an illuminated button.
Thru
Thru is a bypass control. When enabled, emulation processing is disabled 
and DSP usage is reduced. Thru is useful for comparing the processed settings 
to the original signal. Thru is identical to the OFF position in the IPS control 
(page 548).
Note: DSP usage is reduced only when DSP LoadLock (page 74) is disabled. 
If DSP LoadLock is enabled (the default setting), activating Thru will not reduce 
DSP usage.
Input
Input mode emulates the sound of the A800 through the machine electronics 
only, without tape sonics. This is the scenario when the machine is in live mon-
itoring mode but the tape transport is not running.
Sync
Sync mode models the sound of direct recording and playback via the 
sync/record head, plus all corresponding machine electronics.
