19″ 4U Rack Enclosure


Warranty: 1 Years

Product Description

Gemini H is a 4U, 19″ rack enclosure for use with rack mount modeling units, power amplifiers, multi-effects, and other industry standard 19″ pro-audio devices. Slide your device into the rack, and sit on top of the Gemini cabs to build your own modeling stack. Gemini-H provides the appearance and convenience of a classic tube amp to your rack mount gear.


The top 2U space is open as standard to fit most modeling amps and effects units. The 16″ depth comfortably accommodates full length devices. A 2U face plate in the bottom space is finished with quality black grill cloth, and silver trim to match the Gemini cabinets for a boutique half stack appearance. The face plate can be removed to access the additional 2U of rack space when required. An optional 1U face plate is available for use with 3U rack equipment.

Gemini H is made in the USA from rugged, void free 3/4″ birch ply. Black Tolex covering and chrome hardware perfectly match the Gemini cabinets, and also look great with other cabs. Each unit comes fully assembled with carry handles and a 2U face plate with cloth covering.  The head is finished with silver piping, and four sturdy rubber feet allowing the head to sit on top of a speaker cab, flight case, or studio table. A screw kit is included for securing your equipment into the rack.

The short version is 12″ deep to match the depth of the Gemini 1 and 2 cabinets. The Short Head will accommodate rack units such as the Kemper Profiler and Avid Eleven Rack. The Full Head is 16″ deep to accommodate full size units such as the Fractal Audio Axe-Fx.

Gemini-H heads are now available with integrated Furman Rack Power Conditioners. When you order both a head and a power supply here on the Mission web store, Mission will factory fit the power unit into the head for you at no extra charge. These trusted professional conditioners provide stable power and world class protection for modelers, effects units, and power amplifiers. Mission Engineering is a Furman Authorized Dealer.

    Purchased the full length for my Axe FX 2 XL. Exceptional quality and if I ever need an extra 2u I can remove the bottom mesh area. Fantastic!

    Was in bed sleeping and was alerted by my protectors (two small dogs) that the UPS truck was outside. Jumped up excited knowing my Gemini HL was coming to door. Opened box and first impression was wow! Nothing but first class! Very well made. I had ordered it from guitar center in Orange Park Florida. The only disappointment was when I received it there was a zip lock bag with only 4 screws which I need 8 screws to mount my axe fix xl and carvin hd1500 power amp both which are 2U units. Don't know if its standard to ship with 4 screws so If you are planing on puttion more than a 2U unit make sure you specify about the screws. I criss crossed the screws on my axe and power amp which slide into the unit with a precision fit while I am waiting on 4 more screws from Mission Engineering through an email request. Next week will be receiving 2 Gemini 1x12 P1 passive cabs to go with this classy Gemini HL head. The next curve will be trying to master all the buttons on the axe fx!!!!

      Gemini-H uses standard 10-32 rack mount screws which you can use for mounting additional units. Guitar Center has a 25 pack . We also have a 50 pack available on the Mission web store for $8.99.

    I use two Eleven Racks simultaneously, each connected to each other and to two separate Gemini2 Bluetooth Cabinets for stereo guitar play. Although I could place both Eleven Racks into one GMHS, I purchased TWO GMHS rack covers because I also use two Voodoo Lab Ground Control Pros. This way, cable connections from Eleven Racks to each cabinet is better for me. Not only are the Gemini H Short rack enclosures high quality ... they also look great!
