How to connect a DAC to your Mac and play in high resolution
An external DAC turns your Mac’s digital audio into an analog signal with better quality than the built-in output, and lets you play high-resolution files at their original sample rate. Connecting one is easy; what changes the result is setting it up properly.
1. Connect the DAC
- Use a USB or Thunderbolt cable straight to the Mac, ideally with no hub in between.
- Turn the DAC on and wait for macOS to recognize it. If it has its own volume control, set it low before you start playing.
2. Check which formats it accepts
macOS’s Audio MIDI Setup app (in Utilities) lists the formats each device offers: sample rates and bit depth. That tells you how far your DAC goes, for example 24-bit and 192 kHz.
3. Choose the DAC as the output in your player
Select your DAC as the output device in Sonora. Turn on exclusive mode and automatic sample-rate switching: the player sets the DAC to each song’s rate instead of letting the system resample. You’ll find why that matters in our bit-perfect guide.
4. Verify the signal
With a high-resolution file, look at Sonora’s signal path: it should show the file’s sample rate at the output (for example, 24-bit and 96 kHz) and the bit-perfect indicator. If you see an unexpected rate change, check exclusive mode and automatic sample rate.
DSD
Sonora plays DSD files (DSF and DFF). For them to reach the DAC as DSD, the DAC must accept DSD over PCM (DoP). If it doesn’t, the audio is converted before it is sent. Note that equalizer and DSP can’t be applied during DoP playback.
Common problems
- No sound: check that the DAC is selected as the output and that its volume isn’t at zero.
- A click when the track changes: it can happen when the DAC switches sample rate. Many DACs do it and it is normal; a different cable or port sometimes helps.
- Lower sample rate than expected: macOS shared mode may be resampling. Turn on exclusive mode.
- Bluetooth is never bit-perfect: use a cable.
