DAC Setup Guide · macOS

To optimize the sound quality of your external DAC connected to a macOS computer via USB cable, it's crucial to configure the DAC correctly.

 

This guide will walk you through the process of setting up your DAC and adjusting its MIDI settings and sampling rate to match your audio source. Additionally, we'll explore how enabling exclusive mode control of the USB DAC can significantly enhance the audio output, delivering superior sound quality.

 

Let's dive in!

Getting the Best Sound from Your External DAC on macOS

  1. Connect a USB 2.0 Type A/B cable (also known as a printer cable) from the MacMini (or any Mac computer) to the external DAC's USB input port.

  2. Once the DAC is powered on, macOS will detect the USB connection.

  3. Allow the USB connection by clicking the "Allow" button when prompted.

Now that you've successfully connected an external USB DAC to your Mac computer, the next step is to choose your music playback software. If you primarily stream music via Tidal or another streaming service, the Tidal app is sufficient. However, if you're looking for more powerful software to manage your music library and enhance your listening experience, you may consider Roon, Audirvana, JRiver, and others.

​

In this section, we'll showcase the possible setups using these software options and how you can optimize the settings for what we believe is the best sound quality.

  3. If you do not use the digital volume control via the Tidal app, please enable "Force Volume".

  4. Force Volume ensures that the volume control is handled exclusively by the DAC instead of the software. This bypasses the digital volume control in the app, providing a purer, unaltered audio signal. It's important to note that digital volume control can degrade the audio quality compared to using the analog volume control on your amplifier or DAC.

TIDAL: Exclusive Mode

  1. Hit on the "Resolution" icon. An "Audio Quality" pop-up will appear. Select "HiFi/Master" resolution for the best sound quality.

  2. Selecting the maximum resolution ensures that you are streaming music in its highest possible quality, providing you with the best listening experience. This setting allows you to enjoy Tidal's HiFi and Master quality audio, which offers superior sound fidelity compared to lower resolution streams.
