Quick Guide
The Schiit Midgard is a fully-discrete high-power headphone amplifier and preamp featuring the Halo mixed-mode feedback system. Please note the following critical operational details:
- Power Requirements: Use only the supplied AC wall-wart (14-16VAC, 1-2A). Do not use DC power supplies.
- Startup Delay: There is a normal 8-10 second delay after turning the unit on before sound is output to the headphones.
- Preamp Outputs: Both balanced and single-ended preamp outputs are always active and do not mute when headphones are plugged in.
- Headphone Protection: If sound drops out or the amp clicks, it may be in over-current protection mode, often caused by shorted cables or incompatible TRRS headphone plugs.

Practical help
Common problems
Sound drops out and the amp clicks
The unit is in over-current protection. Check for shorted headphone cables or incompatible TRRS plugs. Use a proper adapter if necessary.
Hum through headphones
Check the source device for the cause of the hum or use a ground loop breaker (e.g., EbTech HumX).
No sound immediately after turning on
This is normal. The amp delays headphone output for 8-10 seconds after power-on.
Unit does not turn on
Ensure the AC wall-wart is securely plugged into a working outlet.
Before use
- Verify you are using the supplied 14-16VAC, 1-2A power supply.
- Ensure your headphones use a standard 1/4 inch or 4-pin XLR plug.
- Check that your source cables (XLR or RCA) are connected to the correct inputs.
- Confirm the input switch is set correctly (Out for XLR, In for RCA).
Specs in practice
- Preamp Outputs
- These outputs are always active and do not mute when headphones are connected.
Images and diagrams
- The rear panel contains the AC power input, balanced/SE inputs, and balanced/SE preamp outputs.
- The front panel contains the input switch, gain switch, volume knob, and both 1/4 inch and 4-pin XLR headphone jacks.
Model compatibility
- 1/8 inch TRRS-terminated headphones (with microphones) may require a specific adapter to avoid shorting the outputs.
- Preamp outputs are always active; consider a remote switch if using active monitors that you wish to mute.
