Operating the LMS-D24 and D26
The unit will energise 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
There is a library of thirty Factory Presets to suit a range of Turbosound enclosures.
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 that 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 parameter 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 version of a Factory Preset in any free preset location.
Details of all the Factory Presets can be found in Appendix A.
Creating a Crossover
In addition to the Factory Presets the unit has two further ‘Base Presets’; mono and stereo.
These Base 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 locked but the user can name and store their
own edited versions in any free preset location.
