27 / 65 page – 27 – CXD2724AQ-3 8. Applications The CXD2724Q is equipped with various applications such as Dolby Pro Logic Surround mode (Pro Logic mode), Virtual Dolby Surround mode (Virtual mode), Dolby 3 Stereo mode, noise sequencer mode, SFC mode, and DSP bypass mode. The methods of setting each mode and of changing the mode are described below. Note) The filter and other parameter values for each application assume a sampling frequency (fs) of 44.1 [kHz]. Consult your Sony representative with regard to use at other fs. 8-1. Dolby Pro Logic Surround Mode (Pro Logic Mode) Pro Logic mode is realized using the adaptive matrix, passive decoder including BNR, auto input balance, center channel mode control, simple SFC and other functions. (1) Setting Pro Logic Mode Pro Logic mode must be set by the following procedures in order to achieve stable adaptive matrix operation. Setting Pro Logic mode by procedures other than those given below may aggravate the decoder characteristics. • Immediately after power-on reset i) Transfer the following setup data. SQA = 0030H (Field A) SQD = 7ee7H (Field D) ∗ Field C is "All 0", so the DAC forced mute is applied. ii) Transfer the Pro Logic mode coefficient data. iii) Transfer the setup data set in Pro Logic mode. • Changing to Pro Logic mode from Virtual mode Note) The coefficients for the Pro Logic mode soft mute∗1 status must be set in coefficient RAM addresses 00H to 7fH before shifting to Virtual mode. i) Apply the soft mute in Virtual mode. ii) Transfer the setup data set in Pro Logic mode. iii) Cancel the Pro Logic mode soft mute. • Changing to Pro Logic mode from a different mode (other than Virtual mode) i) Apply the soft mute in the current mode. ii) Set the coefficients at the following addresses to "0000H". Addresses: 6eH to 7fH iii) Transfer the following setup data. SQA = 0030H (Field A) SQD = 7ee7H (Field D) ∗ The DAC forced mute is not applied by Field C. iv) Transfer the Pro Logic mode coefficients for the soft mute status. v) Transfer the setup data set in Pro Logic mode. vi) Cancel the Pro Logic mode soft mute. ∗1 Soft mute: See "Appendix 1. Soft Mute". |
