Applies to: Scarlett 8i6 (1st Gen) and 18i6

For any problem you may be experiencing, please ensure that you have the latest software for the 8i6 from here. If this doesn't help, see the steps below:

My Scarlett isn't powering up

The Scarlett 8i6 (1st Gen) + 18i6 interfaces aren't bus-powered, so you will need to ensure that the supplied power adapter is connected to a power supply.

I am having connection or performance problems

• Optimise your computer through the appropriate guide found here.
• Try increasing the buffer size in your audio software.
• If you have other USB devices connected, try disconnecting them.

I'm getting no signal from the input on the meters or in my DAW

• Ensure that you have sufficient gain by turning up the gain dial on the front of the unit.
• If inputting a signal from a microphone, ensure that the microphone is plugged into the XLR socket of the input.
• If inputting an instrument signal, ensure that you are using the jack input socket and that the “inst” switch is engaged. If the channel doesn't have an “inst” switch, move the jack to input 1 or 2.
• If inputting a line-level signal, ensure that you are using the jack input and that “inst” is not engaged.
• If using a condenser microphone, ensure that you have phantom power switched on.
• Check your audio source and cable to ensure that they work.
• Ensure that your DAW is correctly configured to use your 8i6.

The locked light is not lit

This means that your interface cannot lock to the sync source set in Scarlett MixControl

• If you are not using the digital inputs, ensure that the sync source is set to “Internal” in Scarlett MixControl.
• If you have another device connected to the S/PDIF input and would like to use that device's digital clock, set both devices to the same sample rate and set the sync source in Scarlett MixControl to “S/PDIF”.

I'm experiencing high latency in my DAW

• Reduce the buffer size in your DAW.

Please note: reducing latency and buffer sizes will increase CPU load and will require more resources. If there are no sufficient resources available, you may need to increase the latency and buffer size.
