3. Input Channel Level Meter - Shows the post-converter digital signal level coming into the channel�
4. Input Icon - Shows the input type selected from the Analog Level drop-down�
5. Analog Level - Use this drop down menu to choose the analog level for each A/D conversion channel�

microphone preamplier circuit.
• Choose +4dBu when connecting to “pro” gear, such as an external mic pre, compressor, or EQ, with outputs at a
+4dBu nominal level�
• Choose -10dBV when connecting to “semi-pro”, hi-, or musical instrument gear with outputs at a -10 dBV nominal
level�
6. Input Gain Control - Use to adjust the gain of the microphone preamp� Not available when the input is set to +4dBu or -10dBV�
7. Input Settings - Provides options for the various inputs:
• Phantom Power: Use this button to enable 48 volt phantom power on the corresponding Analog In channel�

• Group: The input gain controls of adjacent odd-even channels are adjusted simultaneously. Any level osets
that exist before inputs are grouped will be preserved after a group is chosen�
