OUTPUT CONFIGURATION
Helike 1.0 UA-E3010 supports multiple USound output devices shown in Table 1. Helike 1.0 UA-E3010
offers the possibility to load filters from the MicroSD card that optimize the acoustic characteristics of each
of the devices. The configuration files that are used for these devices can be downloaded from
https://github.com/usound-tech/audio_device_configuration
. They must be copied onto the MicroSD card
and placed in a folder named “usound” as shown
in Figure 4 for Helike 1.0 UA-E3010 to recognize and to
load the parameters.

Based on the output device selected, the DIP switches S1-1 through S1-4 need to be set accordingly. This
ensures that the correct configuration file is loaded from the MicroSD card, and hence that optimal sound
quality is reached for the corresponding device Table 6 shows the various DIP switch options.
Helike 1.0 UA-E3010 can be used without installing a MicroSD card in USB input and I2S input mode.
However, if configuration loading is enabled by setting DIP switches S1-1 through S1-4 to anything other
than 4x Off, no filter will be loaded, and Helike 1.0 UA-E3010 will playback audio without configuration.
This state is signaled by LED 3 (orange) illuminating or blinking.
