I Microphone Input. The MIC input may be either line-level or –20 dB from line-level (the
difference being made up through a software controlled 20 dB gain block). The mono MIC
input may be sent to the left and right channel of the ADC for conversion, or gained/
attenuated from +12 dB to –34.5 dB in 1.5 dB steps and then summed with left and right
line OUT before the Master Volume stage.
I Left Line-Level Input. The left line-level input may be sent to the left channel of the ADC;
gained/attenuated from +12 dB to –34.5 dB in 1.5 dB steps and then summed with left line
OUT (L_OUT).
I Right Line-Level Input. The right line-level input may be sent to the right channel of the
ADC; gained/attenuated from +12 dB to –34.5 dB in 1.5 dB steps and then summed with
right line OUT (R_OUT).
I Left Synthesizer Input. The left MIDI upgrade line-level input may be sent to the left
channel of the ADC; gained/attenuated from +12 dB to –34.5 dB in 1.5 dB steps and then
summed with left line OUT (L_OUT).
I Right Synthesizer Input. The right MIDI upgrade line-level input may be sent to the right
channel of the ADC; gained/attenuated from +12 dB to –34.5 dB in 1.5 dB steps and then
summed with right line OUT (R_OUT).
I Left CD Line-Level Input. The left CD line-level input may be sent to the left channel of
the ADC; gained/attenuated from +12 dB to –34.5 dB in 1.5 dB steps and then summed
with left line OUT (L_OUT).
I Right CD Line-Level Input. The right CD line-level input may be sent to the right channel
of the ADC; gained/attenuated from +12 dB to –34.5 dB in 1.5 dB steps and then summed
with right line OUT (R_OUT).
I Left Video Input. The left audio track for a video line-level input may be sent to the left
channel of the ADC; gained/attenuated from +12 dB to –34.5 dB in 1.5 dB steps and then
summed with left line OUT (L_OUT).
I Right Video Input. The right audio track for a video line-level input may be sent to the
right channel of the ADC; gained/attenuated from +12 dB to –34.5 dB in 1.5 dB steps and
then summed with right line OUT (R_OUT).
O Left Output. Left channel line-level post-mixed output. The final stage passes through the
Master Volume block and may be attenuated 0 dB to –45 dB in 1.5 dB steps.
O Right Output. Right channel line-level post-mixed output. The final stage passes through
the Master Volume block and may be attenuated 0 dB to –45 dB in 1.5 dB steps.
I Phone Input. Line-level input from a DAA/modem chipset.
O Phone Output. Line-level output from a DAA/modem chipset.
O Phat Stereo Phase Expander filter network, resistor pin.
I Phat Stereo Phase Expander filter network, capacitor pin.
