When using Apogee interface with Cubase, Sonarworks, output volume level goes to max.

Symptom: When opening a session or selecting Apogee as the audio device, the output goes to full volume every time.


  • In Cubase, go to Devices > Device Setup > Control Panel > Core Audio Device Settings. Under Options, verify that set device attenuation to 0 dB is unchecked.

NOTE: In Cubase 10 and up, this setting is in Studio Setup > Control Panel

  • In Sonarworks, go to Systemwide settings and deselect the “Adjust output device gain checkbox.

How is this possible? All modern Apogee interfaces have input gain and output volume that are digitally controlled rather than an analog potentiometer that must be physically turned. The advantages of digital control are many:

  • Improved Sound Quality (turning the gain doesn’t cause a “scratchy” sound, and enables the advantages of our Step-Gain preamp technology)
  • Settings can be saved to presets that can be recalled later.
  • You can also control the output volume directly from the Mac’s Keyboard, Touchbar, or Volume icon in the Task Bar.

Cubase:  In Cubase this is called “Device Attenuation.”  The intent of this setting is to attenuate, or lower your volume, so you don’t get blasted.  When selecting any audio device with this setting turned on Cubase sets the device’s output volume to 0, since most simple sound cards have 0 as the lowest value.  Since your Apogee is rating the Outputs in digital decibels, where 0dBFS is the highest value, this setting will have the unfortunate opposite result, maxing out the volume.  Be sure to disable this setting to prevent getting blasted.

Sonarworks Reference 4:  This is a sound calibration software that many customers may have and forget is even running.  It has a setting to Auto adjust output device gain, or volume.

Please remember, many other softwares not listed here have these types of settings so be sure to check all the softwares on your computer!

I can’t change the Symphony 64 card source port setting in System Preferences

Symptom: Port Source Setting for Symphony 64 cannot be successfully changed from System Preferences/Sound.

Solution: There is a known issue with changing the Symphony64 card Source setting from 1 port to 2 ports or vice versa can cause “System Preferences/Sound” to hang or “beach ball”

We recommend using Audio MIDI Setup (found in Applications > Utilities > Audio MIDI Setup) to change the Symphony64 card Source for the ports. Always remember to quit all applications and restart the computer after changing the number of ports.

How do I use the custom I/O labels in Logic?

For Logic 9 and lower:

With your Apogee devive selected as the input/output in Logic’s Audio Preferences, go to the “Options” menu and select “Audio” and then “I/O Labels”. Now you can select the custom Apogee labels for your device.

For Logic X and higher:

  • Go to Logic’s Mix menu at the top of the screen and select “I/O Labels…”
  • There are several columns: Channel, Provided by Driver, User, Long, & Short.
  • To use the labels provided by the Ensemble:
    • Click the button in the Provided by Driver column.
  • To enter your own custom label:
    • Click the button in the User column.
    • Double click the “-” in the Long column, type in a new name, then press Return on your Apple keyboard

Can I use Symphony I/O with AD16x, DA16x, or Rosetta 200/800 when connected to Symphony64?

Yes, Symphony I/O can be used with Legacy interfaces if you’re using the most current release.  Please note the following instructions to do so:

  1. The rule for Symphony I/O connection is- “1 Symphony I/O per port”, so that means the supported configuration is 1 Symphony I/O on port 1 of the Symphony64 Thunderbridge or PCIe card and any Legacy interfaces on port 2 of the Symphony64 Thunderbridge or PCIe card. You can’t daisy-chain Symphony I/O’s, but you can daisy-chain Legacy interfaces.
  2. First, make sure your Legacy interface (AD16x, DA16x, Rosetta 200, Rosetta 800) have an X-Symphony option card properly installed with the current X-Symphony firmware (version 2.7)
  3. Connect your Symphony I/O directly to your computer’s USB ports- don’t use a hub. Power up the Symphony I/O.
  4. Download the latest Symphony I/O Release package from our website and follow these instructions.
  5. After the firmware has successfully updated, connect the Symphony I/O to the first port of the Symphony64 Thunderbridge or PCIe card using a PC-32 cable. Connect one end of the cable to the “main port” on the back of the first Symphony I/O and the other end of the cable to the 1st port (on the left) of the Symphony64 Thunderbridge or PCIe card.
  6. Connect the 1st Legacy device to the 2nd port of the Symphony64 Thunderbridge or PCIe card using a PC-32 cable. Connect one end of the cable to the “primary port” on the back of the 1st Legacy device and the other end of the cable to the 2nd port (on the right) of the Symphony64 Thunderbridge or PCIe card. Chain any additional Legacy devices using the “primary” and “expansion” ports.
  7. If you’re using multiple Legacy devices, send the Word Clock output of the 1st Legacy device to the Word Clock input of the 2nd Legacy device and so on, using BNC cables and t-connectors, if necessary.
  8. Send the Word Clock output of the Symphony I/O to the Word Clock input of the 1st Legacy device using a BNC cable.
  9. Make sure the Symphony I/O is set for “SYM AIM” (Symphony Audio Interface Mode) by pressing in and holding on the right side encoder on the front-panel until it brings you to the AIM menu. If it says “Symphony”, it’s already in SYM AIM… you can just push in on the encoder again to exit the menu. If not, scroll through the menu until it says “Symphony” and then push in on the encoder again. The unit will power down and restart itself in SYM AIM.
  10. Power up all the Legacy devices and make sure they’re set for “External Word Clock” as their clock source.
  11. Run the software installer included in the Release download. Restart the computer.
  12. After the computer restarts, open up “Audio MIDI Setup” (Applications> Utilities> Audio MIDI Setup). Select “Symphony64” in the left-hand device column. Make sure it’s selected as your computer’s default i/o. The speaker and microphone icons should appear next to it… if they don’t, click on the drop-down menu below with the “gear” icon and select both “Use this device for sound input” and “Use this device for sound output”.
  13. With “Symphony64” selected in Audio MIDI Setup, go to the center part of the Audio MIDI Setup window and set the “Source” drop-down menu to ‘Ports 1-2: 64Chs’. Quit Audio MIDI Setup and restart your computer.
  14. After the computer restarts, wait for the system to configure- the exclamation mark (!) icon on the front-panel of Symphony I/O will eventually go away and the Legacy units will switch to “Ext” clocking… After this happens, launch Maestro2 and confirm that all the interfaces show up properly. If a device is showing up as the wrong unit, such as a DA16x in Advanced routing showing up as an AD16x,  go to the “Device Settings” tab in Maestro2, highlight the device in the left-hand device column and then select “DA16x” in the “Device Type” drop-down menu. Quit Maestro and restart the computer. If an AD16x in standard routing is showing up as a Rosetta800, quit Maestro and restart the computer.
