Mono Mixer Control
The TAS3004 device contains a second mixer that performs the function of mixing left and right channel digital audio
data from the input mixer in order to derive a monaural channel. This mixer has a fixed gain of –6 dB so that full scale
inputs on L_sum and R_sum do not produce clipping on the resulting L+R_sum.
The output of this mixer is present on terminal 24 (SDOUT2) and is generally used for a digitally-mixed subwoofer
or center channel application.
4.5
Treble Control
The treble gain level may be adjusted within the range of 15 dB to –15 dB with 0.5-dB step resolution. The level
changes are accomplished by downloading treble codes (shown in Appendix A) into the treble gain register.
Alternately, a limited range of treble control is available by asserting the GPI terminals.
The treble control has a corner frequency of 6 kHz at a 48-kHz sample rate.
The gain values for treble control can be found in Section A.3.
