Microphone Input. T he 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). T he 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.
Left Line-Level Input. T he 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 ).
Right Line-Level Input. T he 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 ).
Left Synthesizer Input. T he 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 ).
Right Synthesizer Input. T he 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 ).
Left CD Line-Level Input. T he 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 ).
Right CD Line-Level Input. T he 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 ).
Left Video Input. T he 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 ).
Right Video Input. T he 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 ).
Left Output. Left channel line-level post-mixed output. T he final stage passes through the
Master Volume block and may be attenuated 0 dB to –45 dB in 1.5 dB steps.
Right Output. Right channel line-level post-mixed output. T he final stage passes through
the Master Volume block and may be attenuated 0 dB to –45 dB in 1.5 dB steps.
Phone Input. Line-level input from a DAA/modem chipset.
Phone Output. Line-level output from a DAA/modem chipset.
