When using Duet2, Duet for iPad & Mac, Quartet, and Ensemble Thunderbolt, it is important to remember that any of the dual XLR-1/4″ combo jacks are set up so when the input is set to ‘Mic’ or ‘Line’ (+4dBu or -10dBV), only the XLR part of the jack will receive signal. This means that you will need to use an XLR cable or a cable with an XLR adapter connected to it.

The same is true in reverse- when the input is set for ‘Instrument’, only the 1/4″ part of the jack will receive signal.  This means that you will need to use a 1/4″ cable.

 

Here are some examples for setting up different types of input sources on Duet, Quartet, and Ensemble Thunderbolt:

 

Mics

Connect your Mic using only an XLR cable (no 1/4″ adapters or cables) to the XLR input jacks on your Apogee device.

Launch ‘Apogee Maestro’ from your Applications folder, go to the ‘Input’ tab and ‘Analog Level’ drop-down menu for whichever input you’re using to ‘Mic’.

If you’re using a condenser mic that requires phantom power, engage the ’48′ button on the input you’re using.

Gradually bring the input level in Maestro up until you get a good level from your input source. Make sure the meter isn’t going into the red.

 

 

Guitars, Basses, Keyboards, Hi-Z Mics that have 1/4″ cables, such as harmonica mics:

Connect your Instrument using only a 1/4″ instrument cable to the 1/4″  input jacks. (be sure that you’re connecting to the 1/4″ inputs on the combo XLR-1/4″ jacks and not the 1/4″ output jacks)

Launch ‘Apogee Maestro’ from your Applications folder, go to the ‘Input’ tab and ‘Analog Level’ drop-down menu for whichever input you’re using to ‘Instrument’.

Gradually bring the input level in Maestro up until you get a good level from your input source. Make sure the meter isn’t going into the red.

 

Sending Line-Level audio to your Apogee device and bypassing it’s mic-pres

Connect the output from your line-level piece of gear (such as a compressor or external mic-pre) to the XLR input jacks. If your Line-Level device only has 1/4″ outputs, you will need to use balanced 1/4″ to male XLR cables. You can’t use the 1/4″ input jacks on your Apogee device, as they are only used for guitars/basses/keyboards.

Launch ‘Apogee Maestro’ from your Applications folder, go to the ‘Input’ tab and ‘Analog Level’ drop-down menu for whichever input you’re using to ‘+4dBu’ (for use with professional audio gear) or ‘-10dBv’ (for use with consumer audio gear).
