Tech Specs
The reference card for the install team.
danger
The figures here are working limits. If you choose to operate outside them, you do so at your own risk.
Power
| Supply voltage | 9–24V DC |
| Recommended supply | 12V or 24V, 1A minimum |
| Connector | 5.5 × 2.1 mm barrel jack, center-positive |
warning
Do not exceed 24V on the supply input. Higher voltages will damage internal components.
Outputs
Multistate channels (1–6)
| Current rating | 1.5A continuous |
| Voltage range | Up to 24V DC |
| Modes | Mechanical relay or solid-state, software-selectable |
Standard channels (7–8)
| Current rating | 3A continuous |
| Voltage range | Up to 24V DC |
| Type | Mechanical relay |
We don't support running mains AC voltage through any IgorBox channel.
Inputs
| Channels | 2 |
| Type | Optically isolated, polarity-insensitive |
| Voltage range | 6–48V AC or DC |
Audio
| Output | Stereo line level, 3.5 mm TRS jack |
For best results, feed the controller 44.1 kHz / 16-bit lossless audio (WAV or FLAC).
Connectivity
| Ethernet | 100Base-T, RJ45 |
| WiFi | 2.4 GHz, 802.11 b/g/n |
Storage
32 GB onboard, formatted for low-latency audio playback. Not user-serviceable. If you need more, talk to us.
Mechanical
| Case material | Aluminum extrusion + ABS endcaps |
| Mounting | Wall, rack (with optional ear kit), DIN rail (with optional clip) |
| Operating temp | 0–50 °C |
| Storage temp | -20–70 °C |
The chassis is the same size as the MKI, so existing mounting hardware fits.
