10 OPERATION
10.11.6 EQ5 5-band Equalizer
Parameter Address Usage
playMode 0x1e09 bit 5: EQ5 enable
eq5Params 0x1e12/1b Frequency/gain pairs
eq5Update 0x1e1c Indicator that settings have been changed
The 5-band equalizer takes its parameters from array, which needs to be written
before the EQ5 is enabled from bit 5 of . If the settings are changed while EQ5 is
active, new settings can be forced to be taken into use by writing a non-zero value to .
Currently EQ5 and Bass/Treble control can not be active at the same time. Bass and treble
controls override EQ5.
eq5Params are as follows:
Parameter Address Low High Usage
eq5Dummy 0x1e12 0 0 Not used
eq5Level1 0x1e13 -32 32 Bass level in dB
eq5Freq1 0x1e14 20 150 Bass/Mid-Bass cutoff in Hz
eq5Level2 0x1e15 -32 32 Mid-Bass level in dB
eq5Freq2 0x1e16 50 1000 Mid-Bass/Mid cutoff in Hz
eq5Level3 0x1e17 -32 32 Mid level in dB
eq5Freq3 0x1e18 1000 15000 Mid/Mid-High cutoff in Hz
eq5Level4 0x1e19 -32 32 Mid-High level in dB
eq5Freq4 0x1e1a 2000 15000 Mid-High/Treble cutoff in Hz
eq5Level5 0x1e1b -32 32 Treble level in dB
Freq values must be strictly ascending: e.g. eq5Freq2 must be higher than eq5Freq1, so e.g.
combination 80, 50 is not allowed.
Example: Vector 0, 12, 70, 6, 300, -3, 3000, 2, 8000, 6 emphasizes bass and treble a lot.
