Starting up
The unit will energize as soon as power is applied to the IEC inlet; there is no power switch. During the start
up process the firmware application model number and version numbers are displayed and the outputs are
muted until the unit has completed its internal checks. Once the start-up routines are complete and the unit
is ready to pass audio, the DSP signal path will be restored to the current settings when it was last powered
down and the audio signal is gradually ramped up to its correct level.
Selecting a Factory Preset
• The Bag End Kairos DSP series processors have a library of Factory Presets designed to suit a
range of applications.
• Factory Presets contain some parameters that are fixed and hidden from view; the remainder of the DSP
parameters are available for user manipulation. The number and type of hidden parameters is dependant
on the Factory Preset. Typically crossover frequencies, output delay and some EQ’s are hidden. Those
settings are a function of the loudspeaker cabinet design and should not require adjustment for different
applications.
• To recall a Factory Preset for a particular cabinet or system, press Recall and use the left hand param-
eter knob a to scroll through the available Factory Preset locations (as indicated by a box symbol after
the preset number). Once the appropriate preset has been selected press Recall again at which point you
will be asked to confirm the action by pressing Recall for a third time. This is to guard against accidental
recall of presets.
• Factory Presets are locked so they cannot be over-written. The user can, however, store an edited ver-
sion of a Factory Preset in any free preset location. Details of all the Factory Presets including output
designations can be found in Appendix A.
Added Delay in Some KS26 Loudspeaker Presets
The loudspeaker presets for running any of the CD series loudspeakers in biamp mode along with a sub-
woofer have an additional 10 ms of delay built into the preset for all of the outputs (subwoofer, low fre-
quency and high frequency). This is because the delay settings for the biamp operation of CD series loud-
speaker are locked and cannot be altered by the end user. The delay setting for the subwoofer output is not
locked and can be modified. If there is a large distance between the subwoofer and the CD series loud-
speaker this may need to occur.
If the subwoofer needs more delay, due to it being closer to the intended listening area than the CD series
loudspeaker, the subwoofer output delay can be increased to more than 10 ms. If the subwoofer needs
less delay, due to it being farther away from the intended listening area than the CD series loudspeaker, the
subwoofer output delay can be decreased to less than 10 ms.
Creating a Preset
In addition to the Factory Presets the unit has 22 open presets. These presets are stored in locations 1 and
2 respectively, they can be used to develop settings for any loudspeaker combination and are recalled in the
same way as the Factory Presets described above. These presets are also unlocked and the user can name
and store them, and make their own edited versions in any free preset location.
