Interfacing Linux: Apogee Duet

I wanted to see if I could give this brushed-aluminum brick with a big knob a new lease on life using Linux. While the initial setup was relatively straightforward a CLI tool hinawa-utils was needed to fine-tune the device. If you’re feeling particularly adventurous snd-firewire-ctl-services can be used to control the Duet directly from alsamixer.

Apogee Duet tech specs:

  • Two channels of professional-quality 24-bit/96kHz audio input and output
  • Two balanced XLR inputs, with selectable 48V phantom power on each input
  • Maximum input – +4 dBu setting: 20 dBu; -10 dBV setting: +8 dBV
  • Mic Pre-amp gain: 10 to 75 dB
  • Two unbalanced high impedance instrument inputs
  • One high-level stereo headphone output
  • Two unbalanced -10 dBV line outputs for powered speakers
  • Multi-function controller knob for volume and input gain control and assignable MIDI control
  • Multi-segment LED meters to display input or output levels

ALSA / Pulseaudio: Plugging the Apogee Duet in causes it to be immediately recognized by ALSA and Pulseaudio.

Jack: Configuring the Apogee Duet with Jack is equally straightforward.

Hinawa Utils: This is the CLI tool used to control mic/line settings, phantom power, and mixer sources.

Disable ALSA firewire drivers: If you don’t want ALSA or Pulseaudio to see the device you can disable it with the following.

Create the file alsa-nope.conf in /etc/modprobe.d/ and add the following.

blacklist snd-oxfw

I’ll put it like this. If you are looking for a high quality preamp to drive your SM7B, PR40, RE20 or D2 it’s a no brainer. The line level inputs are more than good enough for recording the occasional track.

However, if you need to record more than two tracks simultaneously, have a condenser mic, need to connect MIDI devices, or the idea of using the command line to change settings both angers and confuses you, run.
