38、 30, 2002 - The * sign next to a control signal name indicates that this control is active low - All of the POD-xt electronics is contained on one PCB titled “SHARCPOD MAIN” Audio system (see page 1 and 2 of schematic): Guitar Input: The guitar input is buffered and amplified by U4-A. U4-A also adds

39、 high frequency pre- emphasis gain starting at about 200Hz. U4-A output is spliced into two branches: - On the upper branch, R25 and R24 divide the signal for a +/-2.5 VPP range ( 5Vpp, 100Hz at guitar input). C61 allows this signal to be DC biased at +2.5V by the ADC input. Q5 and Q4 clip the signa

40、l to a maximum range of 0/5V. The signal drives the left channel of the ADC section of CODEC U8. - In the lower branch, U4-B adds a gain of 5.32 to the signal. C55 allows this signal to be DC biased at +2.5V by the ADC input. The double diode D27 limit the maximum signal swing to a -0.6V /+5.6V rang

41、e before entering the right channel ADC section of CODEC U8. Note that the signal on this branch will clip for guitar input level above 0.310 Vpp. The net result is two signals with a gain difference of 16, each feeding one of the two ADC inputs. Once these signals are converted and moved into the D

42、SP, the DSP code will monitor the amplitude of the signals and use the one of the two versions most appropriate for the current input level. The DSP will also apply a de-emphasis filter complementary to the filter function implemented by U4-A. This scheme allows for significantly improving the signa

43、l noise and low-level distortion performance of the ADC. Audio Outputs: The digital signal from the DSP feeds the DAC section of CODEC U8. The left and right differential outputs of the DAC are amplified by a gain of 8.9 (from the differential DAC output to U18 output) and Low Pass filtered (FC = 20

44、KHz) by U18-A and U18-B. U18 outputs feed the MASTER VOLUME potentiometer followed by two differential buffers made of U29 which drives the ” balanced outputs. Notice that, because of the wiring of the output jack switches, if only one jack is plugged into either the LEFT or RIGHT output, the left and right a
