Pro-Ject - Ground It Deluxe Base 3

The Ground it Deluxe on Magnetic Feet for the Largest Pro-Ject Decks

The Pro-Ject Ground it Deluxe 3 is sold singly. It is a heavy equipment base filled with granular damping material and finished in dark grey piano lacquer, 500 by 65 by 400 millimeters (19.7 by 2.6 by 15.7 inches) and 13.5 kilograms (29.8 pounds). It stands on height-adjustable magnetic feet.

A turntable on a rack or sideboard picks up footsteps, motor hum and speaker energy through the furniture. Pro-Ject makes the Ground it Deluxe to put mass and damping between them, so the turntable rides on the base rather than the shelf.

Pro-Ject makes three versions of the base. The Deluxe 3 is the one sized for the Xtension 9, 10 and 12 Evolution, the Signature 10 and the RPM 9 Carbon.

Three Bases, Three Footprints: Match the Base to the Deck

Fit, Load and Materials

Pro-Ject publishes no load rating for the Ground it Deluxe. It lists the turntables each base is made for, and the Deluxe 3 covers the Xtension 9, 10 and 12 Evolution, the Signature 10 and the RPM 9 Carbon. Any turntable whose plinth and feet fit inside 19.7 by 15.7 inches will sit on it.

The base is 2.6 inches tall with its height-adjustable magnetic feet and 45 millimeters (1.8 inches) without. The magnetic feet carry the base with no spike point touching the shelf at all. Add that to the turntable's height when checking a rack shelf.

The chassis is filled with granular damping material, which is where most of the weight comes from. The lacquer is Pro-Ject's dark grey, made to match the charcoal finish of its turntables. Pro-Ject also offers the base for other hi-fi components.

Who Is the Ground it Deluxe 3 Best For?

• You own one of the decks Pro-Ject names for it — the Xtension 9, 10 and 12 Evolution, the Signature 10 and the RPM 9 Carbon
• Your turntable sits on a rack or sideboard that carries footsteps — the damped mass sits between the deck and the furniture
• You want the base to match the turntable — dark grey piano lacquer, the same tone as Pro-Ject's charcoal finish
• You may move the base under an amp or phono stage later — Pro-Ject offers it for turntables and other hi-fi
• You want the same footprint on spikes for less — the Ground it Deluxe 1 carries the same decks on adjustable spikes

How Do You Set It Up?

Clear the shelf and set the base where the turntable will stand. Level it with the feet until it sits still and does not rock. Lower the turntable onto it, centered, with its own feet on the lacquer. Re-level the turntable if its feet adjust. Cue a record and listen.

Frequently Asked Questions

How many do I need?

One per turntable. The base is sold singly and carries the whole deck. A second base can go under a phono stage or amplifier, which Pro-Ject also offers it for.

Which Ground it Deluxe fits my turntable?

Go by the plinth and the feet you prefer. The Deluxe 3 is 19.7 by 15.7 inches on magnetic feet, for the Xtension Evolution, Signature 10 and RPM 9 Carbon. The Deluxe 1 is the same footprint on spikes. The Deluxe 2 is 17.1 by 13.4 inches for the Debut and Essential.

Spikes or magnetic feet?

The Deluxe 1 and Deluxe 2 stand on adjustable spikes, three or four of them. The Deluxe 3 stands on height-adjustable magnetic feet. All three level on an uneven shelf.

How much height does it add?

About 2.6 inches with the height-adjustable magnetic feet, or 1.8 inches without. Your turntable keeps its own feet and sits on top, so add both when you check the shelf above.

Will the spikes mark my shelf?

Spikes concentrate the weight on a point. On wood or a fine finish, set a spike plate or disc under each one. The Deluxe 3's magnetic feet spread the load without spikes.
