Playback

The Playback panel (shown in Figure 5) has the following configurations:

•

High Performance Stereo Playback - this configuration programs the TLV320AIC3204 in PowerTune™

mode PTM_P3, for low-noise, high-performance stereo playback through both line and headphone

outputs.

•

Low Power Stereo Playback - this configuration programs the TLV320AIC3204 in PowerTune mode

PTM_P1 for low-power stereo playback through both line and headphone outputs.

•

Direct Analog Bypass - this configuration routes IN1_L/IN1_R to HPL/HPR.

•

PGA Analog Bypass - this configuration routes IN1_L/IN1_R to the analog input amplifier (Mic PGA)

which is then routed to both the line and headphone amplifiers.

The analog inputs and outputs used for these configurations can be accessed as follows:

1. IN1_L / IN1_R - Jack J1 or terminal block J2.

2. Line outputs - Jack J7 or terminal block J6.

3. Headphone outputs - Jack J9 or terminal block J8.
