Default

Bits[15:14]

Reserved

Always write as 0 if writing to this register.

Bits[13:8]

Low crossover frequency

The low crossover frequency is the cutoff frequency of the crossover low-pass

filter. This means that only the frequencies under this frequency are sent to the

woofer output. The frequency changes in 10 Hz steps.

000101

0x00 = 50 Hz

0x01 = 60 Hz

0x02 = 70 Hz

0x03 = 80 Hz

0x04 = 90 Hz

0x05 = 100 Hz

0x06 = 110 Hz

…

0x2D = 500 Hz

0x2E = 510 Hz

Bits[7:6]

Reserved

Always write as 0 if writing to this register.

Bits[5:0]

High crossover frequency

The high crossover frequency is the cutoff frequency of the crossover high-pass

filter. This means that only the frequencies above this frequency are sent to the

tweeter output.

000101

0x00 = 50 Hz

0x01 = 60 Hz

0x02 = 70 Hz

0x03 = 80 Hz

0x04 = 90 Hz

0x05 = 100 Hz

0x06 = 110 Hz

...

0x3B = 640 Hz

0x3C = 650 Hz

Tweeter trim

These register bits are used to gain or attenuate the input to the tweeter outputs from

−14 dB to +14 dB in +1 dB steps.

001110

0x00 = +14 dB

0x01 = +13 dB

…

0x07 = +7 dB

…

0x0E = 0 dB

…

0x15 = −7 dB

…

0x1B = −13 dB

0x1C = −14 dB
