Figure 5. Playback Panel

4.1.1.2 Recording

The Recording panel (shown in Figure 6) has the following configurations:

• High Performance Stereo Recording - this configuration programs the TLV320AIC3254 in PowerTune

™ mode PTM_R4, for low-noise, high-performance stereo recording. IN1_L and IN1_R are routed in a

single ended fashion.

• Low Power Stereo Recording - this configuration programs the TLV320AIC3254 in PowerTune ™

mode PTM_R1 for low-power stereo playback. IN1_L and IN1_R are routed in a single ended fashion.

• Differential On-Board Microphone - this configuration programs the TLV320AIC3254's IN3_L and

IN3_R as a differential pair. Jumpers related to the onboard microphone (W1 to W8) must be set to

their default configuration as described in Table 2.

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

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

2. IN3_L / IN3_R - Terminal block J4. Note that the onboard jack J5 must not be used for a differential

configuration.
