-20%19" Fosi Audio V3 Mono Amplifier Rack Mount - 1U (Modular)
- Fosi Audio V3 Mono, the TPA3255 monoblock power amplifier
Fits the Fosi Audio V3 Mono in a 19" rack at 1U, with the power switch and the XLR/RCA selector reachable and the body vented so the Class D amp can breathe. Order it as a single with a blank panel, or as a double that puts a monoblock pair side by side in one U.
CONFIGURATIONS
- 1x: one amplifier plus a blank panel. Fills the full 19" row.
- 2x: two amplifiers mounted side by side across the row.
FITS
- Fosi Audio V3 Mono, the TPA3255 monoblock power amplifier
⚠️ Check the front panel reads V3 MONO before you order. The stereo Fosi V3 is a deeper chassis and has its own mount in my shop.
WHAT YOU GET
- The mounts for the configuration you pick, plus the hardware to join them.
- Rack screws are not included. Use whatever your rack takes.
MODULAR
This is part of my Modular Series. On the 1x, the blank panel swaps for any other 1U Modular Series mount in my shop, so you can add a second device to the row later. Pieces pair within the same U height.
MATERIAL
PETG, not PLA. A Class D amp under load runs warm, and PETG holds its shape where PLA would soften.
A 10" mini rack version of this mount is also listed in my shop, along with the rest of the Modular Series. 💬 For any custom design requests please message me.
