EVALUATION SET
ANANKE 3.0 UA-E1030
QUICK GUIDE
Ananke 3.0 is an audio evaluation set
designed specically for piezoelec-
tric Ganymede MEMS speakers.
The amplier evaluation board fea-
tures two ampliers for driving the
USound earphones and digital signal
processor (DSP). The DSP allows im-
plementation of customised acoustic
lter settings.

Provide power to the Ananke 3.0 evaluation board using 5 V DC-connector
over the POWER plug
Use the 3.5 mm stereo jack cable to connect an audio source (signal gener-
ator, phone, mp3 player) to the INPUT plug in the device
Connect the USound earphones to the OUTPUT (Tiny XLR connector).
This quick setup uses the self-boot option of the DSP. At startup, it loads a pre-
congured set of parameters into the DSP that are stored in an EEPROM.
