Audio Output
Every IgorBox controller has a stereo line-level audio output on the back panel. We've spent a lot of time tuning this circuit — clean, low-noise output ready to feed amplifiers and powered speakers.
Connecting an amplifier or speakers
The output is a 3.5 mm stereo jack, line-level (not headphone-level — don't plug headphones directly into it).
Most show installs feed this into:
- A powered speaker pair (left + right)
- An amplifier driving passive speakers
- A mixer for venues that already have a sound system
You'll want a 3.5 mm TRS to dual-RCA or 3.5 mm to dual-1/4" cable for most amps and mixers. We don't sell those — any music store or Amazon will do.
File formats
Audio plays from the controller's onboard storage — no streaming from the cloud, so latency is low and reliability is high.
| Format | Supported | Notes |
|---|---|---|
| WAV (PCM) | Yes | Lossless, biggest files |
| FLAC | Yes | Lossless, much smaller than WAV |
| MP3 | Yes | Lossy, smallest files |
| AAC | No | |
| AIFF | No |
For best playback fidelity, use 44.1 kHz, 16-bit, lossless (WAV or FLAC). Studio will warn you if you upload media that's outside this sweet spot and it will prevent you from using incompatible audio formats.
When the output is active
The line output produces signal whenever something is playing — show playback, the ambient routine, Live Preview, or Manual Control playback.
If nothing is playing, the output is silent.
When a controller powers on, it plays a brief welcome sound out the audio output — a robotic voice saying "IgorBox" — so you'll know it's awake and the audio path is working. See Boot Sequence for what else happens at startup.
Master volume
- Set a per-clip volume in the timeline editor (right-click an audio clip → Volume)
If you need a hardware volume control on stage, put a powered speaker with a volume knob downstream of the controller, or use a mixer.
