Using Lutefish Stream with a PA (Instead of Headphones)

You can use speakers or a PA system with Lutefish Stream — but it adds a little setup complexity compared to headphones.

This guide explains two common approaches.


Option 1 — Simple Setup (Direct to Powered Speakers)

If you just want basic PA output:

  1. Set up your inputs as you normally would.

  2. Use the headphone output on the Lutefish Stream:

    • ¼” output

    • or 3.5mm output

  3. Run that output directly into:

    • Powered speakers

    • A powered monitor

    • Or a mixer input

Volume Control

  • The large volume knob controls overall output level.

  • Your mix is adjusted in the Mixer tab (just like with headphones).


Option 2 — Advanced Setup (Using a Mixer for Submixes)

If you want more routing control and you have a mixer with aux sends:

Step 1 — Route Your Local Inputs

  • Plug all local instruments and microphones into your mixer.

  • Use an Aux Send (or submix out) to send only your local instruments to the Lutefish Stream inputs.

Important:

  • Do not send the full mix.

  • Only send your local sources to Lutefish.


Step 2 — Bring Lutefish Back Into the Mixer

  • Take the Lutefish headphone output.

  • Plug it into a separate channel on your mixer.

Now you have:

  • Local instruments on their own channels.

  • Remote participants on a separate channel.


Step 3 — Create Your Main PA Mix

Create a mixer output that includes:

  • Your local instruments

  • Lutefish return audio

This output goes to your PA speakers.


Critical Setting: Prevent Hearing Yourself Twice

Inside Lutefish:

  • Go to the Mixer tab

  • Find your orange headphone slider

  • Set it to 1

If you do not:

  • You will hear yourself twice (direct + return path).

  • Setting it to 0 mutes you entirely for everyone.

  • Setting it to 1 keeps it low enough to avoid noticeable doubling.


Why Using a PA Adds Latency

Sound traveling through air takes time.

Approximate rule:

  • Sound travels about 1 millisecond per foot

So if:

  • You’re 10 feet from the speaker

  • You’re adding about 10ms of acoustic delay

This can:

  • Make timing feel slightly behind

  • Be noticeable in tight rhythmic playing

Headphones avoid this entirely.


Alternative: Headphone Amplifier

Instead of a PA, consider:

  • A headphone amplifier

  • Multiple wired headphones

This provides:

  • Zero acoustic delay

  • Better timing accuracy

  • Easier mix control

For real-time collaboration, headphones are always the most stable option.


Quick Summary

  • You can use speakers instead of headphones.

  • Simple method: headphone out → powered speaker.

  • Advanced method: mixer with aux send + return channel.

  • Set your orange slider to 1 to avoid double monitoring.

  • PA systems add acoustic latency.

  • Headphones remain the best performance option.
