SPEAKER ATTACHMENT
Dione Maxi UY-R3020 sound strip
The Amalthea 2.0 UA-R3020 amplifier requires a single-ended input with an input amplitude of 625 mV
rms
.
This output is provided on connector J16 (right channel on Pin 2, left channel on pin 3). Additionally,
Amalthea 2.0 UA-R3020 requires a supply voltage of 30-36 V. This can be provided by
Helike 1.0 UA-E3010 via the same J16 connector. Note that in this case, supplying Helike 1.0 UA-E3010
with the external 36 V supply is mandatory. The connection diagram of Helike 1.0 UA-E3010 in conjunction
with Amalthea 2.0 UA-R3020 and Dione Maxi UY-R3020, is shown in Figure 6.

Optional woofer
If desired, electrodynamic woofers can be connected to the woofer outputs. The built-in TI TPA2028-D1
amplifiers can drive speakers with a nominal impedance of 4
Ω
or higher
.

FOR DIONE MINI UY-R3010
Dione Mini UY-R3010 is a sound strip with 15 MEMS speakers in 3 segments with built-in amplifiers. It
needs to be supplied with 5 V and requires a balanced input signal. The supply and input signal are
provided by the Helike 1.0 UA-E3010 PCB on the Dione Mini UY-R3010 connectors (J15, J23). One
segment has a max. current consumption of 900 mA at a signal frequency of 20 kHz.
