4.12 HP Outputs Tab

Figure 28. High Power Outputs Tab

This tab contains four horizontal groupings of controls, one for each of the high power outputs. Each output has a mixer to mix the LINE2L, LINE2R, PGA_L, PGA_R, DAC_L and DAC_R signals, assuming that the DACs are not routed directly to the high power outputs (see Section 4.10).

At the left of each output strip is a Powered Up button that controls whether the corresponding output is powered up or not. The When powered down button allows 3-state outputs or driven weakly to a the output common-mode voltage.

The HPxCOM outputs (HPLCOM and HPRCOM) can be used as independent output channels or can be used as complementary signals to the HPLOUT and HPROUT outputs. In these complementary configurations, the HPxCOM outputs can be selected as Differential of HPxOUT signals to the corresponding outputs or can be set to be a common-mode voltage (Constant VCM Out. When used in these configurations, the Powered Up button for the HPxCOM output is disabled, as the power mode for that output tracks the power status of the HPL or HPR output that the COM output is tracking.

The HPRCOM Config selector allows a couple additional options compared to the HPLCOM Config selector. Differential of HPLCOM allows the HPRCOM to be the complementary signal of HPLCOM for driving a differential load between the HPxCOM outputs. The selector also allows Ext. Feedback/HPLCOM constant VCM as an option. This option is used when the high power outputs are configured for Capless output drive, where HPLCOM is configured as Constant VCM Out. The feedback option provides feedback to the output and lowers the output impedance of HPLCOM.

At the right side of the output strip is a master volume knob for that output, which allows the output amplifier gain to be muted or set from 0 to 9 dB in 1-dB steps.
