The PreSonus AR12 Rack Ear Mounting Kit provides the hardware to install your StudioLive AR12 mixer into a standard rack. This guide covers compatibility, installation tips, and when this kit is the right choice.
Quick answer
The PreSonus AR12 Rack Ear Mounting Kit is the dedicated solution for securely mounting your StudioLive AR12 mixer into a standard 19-inch rack. It includes the necessary ears and screws, making installation straightforward.
Why use a dedicated rack ear kit?
Using a rack ear kit designed specifically for your mixer ensures a precise fit and proper weight distribution. Generic mounting brackets may not align with the chassis holes or provide the same level of stability.
The AR12 kit includes left and right ears plus mounting screws, so you don't have to source hardware separately. This reduces the chance of using incorrect screws that could damage the mixer's threads.
Trade-off: fixed vs. adjustable rack depth
This kit is made for the StudioLive AR12's specific chassis depth. If your rack has variable depth rails, the kit's fixed ear position may require you to adjust the rack rails to match. It's a minor setup step but worth noting for deeper or shallow racks.
Decision rules for rack mounting your AR12
- Check your mixer model: This kit is only compatible with the StudioLive AR12. It will not fit the AR8, AR16, or other mixer models. Verify your mixer's model number before purchasing.
- Prepare your rack space: The AR12 requires 2U of rack space. Measure your rack's internal depth to ensure the mixer fits without obstruction from rear cables or other gear.
- Installation steps: Attach the left and right ears to the mixer using the included screws. Then slide the mixer into the rack and secure the ears to the rack rails with your own rack screws (not included). Use a screwdriver to tighten the ears evenly to avoid stressing the chassis.
- Consider cable management: After mounting, route cables neatly using tie wraps or a cable comb. This prevents accidental disconnection and keeps airflow clear for the mixer's internal components.
