12 Local presets

All Bias Series amplifiers have an on board memory capable 
of storing up to 50 presets.

An amplifier preset is a snapshot of the current amplifier 
status, including the basic amplifier settings and the DSP 
board settings if a DSP board is present.

12.1 Local preset: Locked presets

When the “locked presets” function is active, a number of 
presets, determined by the “Locked bank size” menu, is not 
overwritable. This function’s status can be toggled on/off by 
entering the Lock code.

If a wrong code is entered, the system simply returns to the 
previous local presets menu.

The preset name can be edited one character at a time. 

12.4.2 Overwriting an existing preset

If the preset location is not empty, the amplifier will ask the 
user confirmation to overwrite the file.
Note that if you have already input a preset name, or if you 
have loaded a preset from local memory or a SmartCard, 
the name is used as starting point for a new save preset 
operation. 

12.5 Local preset: Change lock code

In order to change the lock code used to activate the “Lock 
presets” function, the old user code must be entered.
If the entered code is incorrect, the system returns to the 
previous screen. There is no limit on the number of times 
that an incorrect lock code can be entered.

12.2 Local preset: Locked bank size

This menu allows the user to set the number of locally stored 
presets that cannot be overwritten. Either all (50) or none (0) 
of the presets can be locked. After entering the correct lock 
code, select the number of presets to be write protected.

12.3 Local preset: Recall local preset

In order to recall one of the 50 locally stored presets, press 
ok when the “Recall local preset” line is highlighted.
Navigate forwards or backwards in the existing presets list: 
press the right most button labelled “ok” to load the desired 
preset. If a preset location is not used, it is labelled <empty>. 

12.4 Local preset:Save local preset

12.4.1Save to an empty slot

To save the current amplifier setup as a preset to the lo-
cal memory, enter the “Save local preset” menu. Select an 
empty preset location, press “ok”, and define a proper name.
If no other preset has been loaded in the amplifier either via 
remote control or using a SmartCard, by default the cur-
rent preset name will be “PRESET” followed by the selected 
memory slot name.

12.6 Local preset: Erase all presets

This function allows to erase all non write protected presets 
in the amplifier’s internal memory. After having selected this 
function’s submenu by pressing “ok”, a confirmation screen 
will appear.

Pressing “ok” will erase all non protected presets; when all 
non write protected presets have been erased, a screen 
confirming this will appear.
