ONE: Setup

Why are the input and output level/volume popup indicators not showing up?

Several Apogee products have pop-up level indicator graphics that will appear on the desktop of your Mac when the input and output levels are adjusted from the device or from the Mac’s keyboard volume buttons.


If the pop-ups aren’t appearing, there are a few things to check:

Launch ‘Apogee Maestro 2’ from your Applications folder, click on the ‘Apogee Maestro 2’ drop-down desktop menu and select ‘Preferences’. Confirm that the ‘Display pop-ups’ checkbox is checked. If you don’t see this option, then pop-ups aren’t available for the product you’re using.


If you’ve confirmed that the ‘Display pop-ups’ checkbox is checked and you’re still not getting the pop-ups, try the following:


– Unplug/replug your Apogee device

– Restart your Mac

– Launch ‘Activity Monitor’ (Applications> Utilities> ‘Activity Monitor’), click the ‘View’ drop-down desktop menu and select ‘All Processes’. Type ‘apogeepopup’ in the searchbar in the upper right-side corner of Activity Monitor. Once you see ‘ApogeePopup’ displayed in the list, highlight it and force-quit the process by clicking the ‘X’ button in the upper left-side corner of Activity Monitor. Wait a few seconds and you should see the popups again after adjusting input/output level.


*Note for Duet Firewire and Ensemble Firewire customers*

There was a known issue with pop-ups not working for Duet Firewire and Ensemble Firewire when using any version of Mac OS 10.8. It is recommended that you use either a version of Mac OS earlier than 10.8 or later than 10.9.

Gain Staging – How to set proper levels with your Apogee product and recording software

Use the following steps to set input and output levels on your Apogee interface. 

Before launching your recording software:

1. Turn down the speaker/headphone output level of your Apogee interface.

2. Connect your audio source to your Apogee interface. Make sure to use the proper inputs.

• If you’re using a microphone, plug the microphone into the XLR input.

• If you’re using a guitar, bass, or other high impedance instruments, plug them into the 1/4″ instrument input.

• If you’re using an external mic-pre or another piece of line-level gear, use the XLR inputs.

Quick Tip: Some keyboards and synths can be plugged into either the Instrument or XLR inputs. You might have to experiment with what sounds better.

3. Launch Apogee Maestro and go to the input tab. Make the appropriate selection in the Analog Level drop-down menu for the input channel you are using.

• Microphone (Mic) – depending on the Apogee interface you are using, you would choose Ext Mic/Ext Mic 48v (ONE) or Mic (Duet, Quartet, Ensemble, SymphonyI/O with MicPre module). You will need to engage the 48v button for if you’re using a mic that requires phantom power.

• Instrument (Inst) – Guitar/Bass/some keyboards

• Line Level (+4dBu/-10dBV for balanced/unbalanced connections) – This setting is used when connecting external microphone preamps and other line-level gear.

NOTE: If you have the ONE, a line-input is accommodated by choosing Ext Mic and turning the input gain all the way down.

4. Set the input gain of your Apogee interface.

There are two ways you can adjust your input gain:

• By adjusting the input software encoder in Maestro

• By turning the physical knob (encoder) on your Apogee interface (make sure you’ve set the knob to control the input channel and not the output level. See your User’s Guide for more information on setting this).

Quick Tip: Ideally, the level in the input meter should be as high as you can get it without hitting an “over”. If you see red in the meter, you know you need to turn the input gain down. In some cases you may need to adjust the output of the audio source you are using. You may need to move your microphone closer to the sound source or further away. You may need to turn the level of your guitar or keyboard up or down.

Launch your recording software, create an audio track, and put the track into input or record mode. It is a good idea to leave the fader of the track you are recording and any Master Fader for the mix set at their default setting.

5. Adjust the output level of your Apogee interface.

• Gradually increase the output level of your Apogee interface so you can hear what your input source sounds like in the speakers or headphones.

• After you get the output set to a comfortable listening level, listen for any distortion in the input audio.

• If the audio sounds bad, you may have something set wrong. Go through steps 2, 3, and 4 to trouble-shoot the problem.

Note: Two common issues are that the sound is too quiet or that it’s distorted. It may be a simple case of needing to turn the input gain up and the output level down or the input gain down and the output level up.

Can I record my session on the the startup hard drive?

It’s an accepted “best pactice” of most audio software providers that audio files should be recorded on a hard drive other than the Mac’s Startup drive (i.e. the drive on which the operating system is installed). You can probably get away with recording a few tracks to your computer’s Startup disk, but for the best performance of your Apogee recording system, record onto a separate ATA/IDE, SATA, or FireWire drive whose spindle speed is at least 7200 RPM.

ONE: How do I set a recording level?

Once your microphone or instrument is connected, your audio software is configured and you’ve created a new recording track, just how do you set the input gain for a proper recording level in your audio software? There’s no simple answer, but with a few guidelines and a bit of experience, you’ll master this.

Ideally, the input gain should be set so that when the input signal is at its loudest, the level in audio software (or in Maestro) is just below maximum without lighting the Over indicator.


In reality, it’s unlikely that you’ll be able to guess just the right gain setting to accomplish this – when your gain is too low, the signal never gets close to maximum and when your gain is too high, a digital Over may occur. Now, with a 24-bit system (such as ONE), the noise floor is so low that there’s no real penalty for undershooting the gain setting and recording at a lower level. There IS a penalty

for overshooting the gain setting – a digital Over that results in significantly increased distortion. Thus, it’s better to work with a recording level that’s a bit too low than a level that’s a bit too high.

Just how much to undershoot the gain setting is determined by the nature of the sound being recorded. As a general rule, instruments such as bass and organ have a more consistent level than percussive instruments, such as a tamborine, and may be recorded at a higher level. Also, the performer’s skill and playing style can dictate more or less caution when setting levels. As you gain experience, you’ll be able to more accurately set a good recording level while avoiding digital overs.
