Hardware Control Settings
The LS1 is not just a speaker but a complete playback system. On the left page you see a ow
diagram that illustrates the various internal processes. First there are switches that select a
signal from the various sources. Some sources are connected directly to the LS1, some to the
LS1r Controller box. Then follows a switch that determines whether the LS1 plays back the left
or right channel of a digital stereo pair. Next is a sample rate converter so our DSP can always
linearize the speaker up till very high frequencies, and then there’s an equalizer. The crossover
splits the audio range in two or three bands, dependent on the settings. What follows are EQ’s
for the various drivers (individually calibrated during production) and a delay to compensate for
the acoustic source position of the tweeter and the woofer. Just before the DAC there’s a digital
volume control. This is the best place for digital volume control in a system, since all processing
now takes place before the volume control at maximum resolution.
Many settings of the LS1 can be controlled by the user. The dark dots in the diagram indicate
the two parameters that can be set on the LS1 itself. The grey dots are functions that can be
controlled by the LS1r Controller box or the LS1 Remote Software. The functions with the white
dots can be set in the LS1 Remote Software. Let’s rst look at the controls on the LS1 itself.
Input Sensitivity (input sens)
This switch controls the input sensitivity of the analog input for each speaker between +4dBu
and +19dBu in 1dB steps. The remote software can read and display the position of this switch,
please refer to the chapter ’Software Control Settings‘.
The position of this switch has no inuence whatsoever on the digital inputs.
Channel Switch (Chnl)
If a digital input is used, and when the LS1 Remote software does not run, this switch selects if
the left or right channel of the stereo aes/spdif-signal is played back on the speaker.
Attention: The settings of the LS1 Remote software always have the rst priority. However, as soon as you
use the speakers without the remote software, they will use the setting of the hardware switch again to
determine the channel to play. For that reason it is advised to always put the switch in the right position.
