Device
The console has no password. su <name> sets the level outright;
an unknown name drops to nor. Power-on level comes from EEPROM byte 0x8D
and is normally adm. Controls above your current level are disabled.
Audio nor
Volume is the headphone output, −24…0 dB. up/down step by 2 dB.
Input gain is 0…+36 dB in 1 dB steps. Moving the touch strip on the microphone sends an
unsolicited volume= event, so these track the hardware.
DSP dev / adm
lock on makes the device answer Locked and refuse preset
changes. dspPower off drops VA_EN_n and silences the codec.
Parameter blocks adm
getBlock argument of
114 characters or more — the handler has a memory fault and the MCU resets. This page refuses
those client-side.Panel & LEDs adm / sup
LED ids and driver register numbers are not documented in the teardown — these are
free-form probes. buttonTest on makes the device emit
MUTE_BUTTON PRESSED / SLIDER_UP events into the console.
EEPROM sup
—
128 KB part; only 0x00000–0x054AE holds data. Reads are split
into 256-byte commands and retried, because the device aligns each printed row down to a 16-byte
boundary. Byte 0x8D is the power-on privilege level.
DSP memory sup
—
Valid ranges: 0x0000–0x07FF and 0x1000–0x3FFF as 32-bit words,
0x4000–0x40FA as bytes. 0x0800–0x0FFF answers ErrA.
The part is an Analog Devices ADAU1761.
