Use the following instructions for setting up an input channel in Maestro for use with the SymphonyI/O MicPre module:
1. Plug in an input.
- If you have a microphone, it must connect to an XLR input of the module in card slot 1. If the module in card slot 1 only has inputs via a 25-pin D-sub connector, you will need an XLR breakout cable.
- If you are plugging in a guitar or bass via 1/4" cable, you can plug directly into one of the four 1/4" inputs of the Mic Pre module in card slot 2.
2. Launch the Apogee Maestro 2.app and select the input tab.
Select the Analog Level drop-down menu and choose Mic or Instrument
Quick Tip: Option-click your Analog Level selection to turn all the available channels to Mic or the 1st four channels to Instrument.
After selecting Mic in the input channel's Analog Level drop-down, you will see the following controls:
- Level Trim - Use this knob to adjust the gain of the mic pre.
- Group - Use this drop down to choose a Level Trim group, for controlling the Level Trim of multiple inputs simultaneously. Any level offset that exists before inputs are grouped will be preserved after a group is chosen.
- Insert Select - Use this drop down to insert one of the eight rear panel send/return pairs into the input signal path. Insert labels may be customized in the Device Settings tab window. The insert point occurs after the mic pre and high pass filter and before the A/D conversion stage.
- Insert In - Use this button to enable the Insert Return. The Insert Sent is always active once an insert is selected. Thus, the Insert Send may be used as an analog direct out when an insert is selected but the In button isn't depressed.
- Polarity - Use this button to invert the polarity of the input signal.
- 48 - Use this button to enable 48 volt phantom power on the corresponding Analog IN channel. Condenser mics require 48 volt phantom power to operate.
- High Pass - Use this button to engage an 80Hz high-pass filter on the input.
