2.3. USB Audio Setup

The H9000’s USB B port allows you to send and receive up to 16 tracks of audio from your digital audio workstation.

  • The H9000 works as a Core Audio device in macOS with no driver required. If using Windows, please visit https://etide.io/h9000-support to download and install the Windows driver.

  • The H9000 is always the USB clock source and determines the sample rate.

  • The user must ensure that the H9000’s internal sample rate matches the “H9000 USB Audio” sample rate in your computer’s audio settings.

  • Refer to Section 3.2: Using the H9000 as a Computer Audio Interface for more details about setting up a USB connection.

2.3.1. Reverb Buses

This factory default session demonstrates how you can setup multiple parallel pathways within a single FX Chain. This allows you to take advantages of all 16 channels of USB audio, for a total of eight individual reverb buses.

  • Connect the H9000’s USB B port to your computer.

  • On mac, create an aggregate device that uses your audio interface and the H9000. View Section 3.2.2: Using the H9000 with macOS for more details about creating an aggregate device.

  • Make a note of which I/O in the aggregate device correspond to the H9000’s USB I/O. For example, if you have a 16 I/O audio interface combined with the H9000’s 16 I/O, you will now have a 32 I/O aggregate device. If the H9000 is the 2nd device in your 32 channel aggregate device, channels 17-32 will correspond to channels 1-16 on the H9000.

  • Load the factory default session 901 REVERB BUSES.

  • Create a new project in your DAW of choice.

  • Now, if you create an external audio insert or send/return in your DAW, the aggregate device I/O 17-18 will send audio to channels 1-2 on the H9000 and process it through the Plate reverb algorithm in FX Chain 1.

  • Following this example, channels 19-20 will send audio to the Sizzler Plate algorithm in FX Chain 1, channels 21-22 will send audio to the Room algorithm in FX Chain 2, etc.

Note

If the H9000’s internal sample rate is matched with the “H9000 USB Audio” sample rate in your computer’s settings, but you are still getting the “USB Audio Mute” pop-up message, simply toggle the sample rate of the “H9000 USB Audio” in your computer’s settings to a something else and then back to your desired sample rate to resync the sample rate of the computer and H9000.

2.3.2. Audio Interface

The H9000 can also be used as a USB audio interface, allowing you to take advantage of its pristine audio convertors.

  • Connect the H9000’s USB B port to your computer.

  • Connect the H9000’s XLR outputs to your studio monitors.

  • Create a new project in your DAW of choice, and select the “H9000 USB audio” as your audio interface/playback engine.

  • In Emote’s Direct I/O View, connect the H9000’s USB inputs 1-2 to the analog outputs 1-2. This create a pathway from your DAW’s main outputs to your studio monitors.

  • Create a Direct I/O connection from the H9000’s analog inputs 1-8 to the USB outputs 1-8. This creates a pathway from the H9000’s analog inputs on the DB-25 connector the inputs on your DAW.

  • Now, you can connect a source to be recorded from any of the H9000’s analog inputs directly to your DAW and monitor your DAW’s main mix from the H9000’s analog outputs.
