Our take on the Pro-Ject Phono Box DC by Crutchfield's Dave Bar
Add high-quality vinyl sound to your hi-fi rig
Do you have a turntable, but no phono input on your receiver, integrated amp, or shelf system? Or, does your system's built-in phono stage sound flat and lifeless? No problem — just hook up the Pro-Ject Phono Box DC preamplifer in-line between your record player and any of your receiver's line-level inputs, and you're ready to enjoy your LP collection all over again.
Pro-Ject's clean, simple design uses premium quality parts to deliver the warm, relaxed sound that vinyl is famous for. Its compact all-metal body rejects interference to ensure clean sound, and the gold-plated inputs and outputs resist corrosion for the best possible signal transfer.
This preamp is compatible with both moving magnet and moving coil cartridges, so you can count on proper matching with virtually any turntable and cartridge combination.

Pro-Ject Phono Box DC Reviews
Average Customer Review(s):
Thanks for submitting your review
Phono (MM/MC) Preamp: The Pro-Ject Phono Box allows you to connect a turntable with either a MM (moving magnet) or MC (moving coil) cartridge to today's home receiver's and amplifier which do not offer a dedicated phono input. There is a button on the back of the unit which allows you to switch between MM or MC mode.
Metal Case: The Phono Box's metal case shields the electronics from vibration and electromagnetic interference.
Dual-Mono Circuitry: The Phono Box provides optimal channel separation through dual-mono circuitry and low-noise ICs.
RIAA Equalization: The Pro-Ject Phono Box provides amplification and RIAA equalization for both MM and MC cartridges.
RCA Connections: The Phono Box features gold-plated stereo RCA connections. A stereo RCA input connects your turntable, and a stereo RCA output connects your home receiver or amplifier. RCA cables sold separately.
Ground Terminal: The Phono Box also has a turntable ground, in case your turntable has a separate ground lead. This provides shielding to the tone-arm and the sensitive circuitry in the turntable.
Outboard Power Supply: The Pro-Ject Phono Box operates off of standard household AC current, using the supplied AC power adapter. The external power adapter is separate from the phono preamp to further improve sound quality.
- Input: 100-240V~50/60Hz, 0.6A
- Output: 15V - 500mA (18V)

Need phono pre-amp. [ Keith Feb 27, 2018 ]
I needed a preamp for my old, but still functioning kenwood turntable( with a new stylus). It has a ground wire that had to be screwwed into the preamp. I was told by Drummer that this would cover my needs. I haven,t recieved it yet, so I hoping that all turns out well. [ paul Feb 17, 2018 ]

You had the item I wanted at a competitive price + my local audio/TV store could not supply or obtain it; important to me that they recommended you as good to deal with. [ Clive Nov 14, 2017 ]
My Marantz turntable needed a preamp since my new receiver did not have a phono input. This unit had excellent reviews and Crutchfield has a good reputation. [ LARRY Nov 05, 2017 ]
Receiver didn't have a phono input. I have a moving-coil cartridge so I needed a phono amp that can handle moving-coil. [ Debra Oct 14, 2017 ]
I needed a pre-amp to connect to the integrated amp I chose. I chose a Pro-Ject turntable so I chose a Pro-Ject pre-amp. [ Alex Aug 06, 2017 ]
I am resurrecting my Kenwood KD-2055 turntable. I was going to go new but found that I can connect it to my Denon using a preamp. Inexpensive solution. Jenny at Crutchfield was very helpful in guiding me. Thanks. [ Nestor Aug 05, 2017 ]
I still have a turntable. [ Kenneth W. Jul 26, 2017 ]
I have an old Pro-Ject II turntable, and quite a bit of vinyl, but this excellent receiver does not have a phono input, and even if it did, the Phono sections on receivers are usually pretty poor, even on good quality ones. And I have always wanted one to help improve my vinyl experience. [ Jon Jul 21, 2017 ]
Good reviews. Crutchfield reputation. Great Crutchfield assistance with making selection. [ Kent Jul 13, 2017 ]
Larry's recommendation and the reviews. [ JEFFREY P Jun 16, 2017 ]
Need to hook up my old Pioneer PL514 Turntable to a "line only" tube amp, don't wont to spend two much without knowing if my Pioneer turntable is still worth using. Seen a lot of good reviews on this pre amp. [ Terry Apr 27, 2017 ]
I bought this to augment my meager HiFi setup. I have a Pro Ject Carbon Debut DC turntable running directly to an Onkyo TX 8020 amplifier via it;s built in phono input but thought that the sound could be a little fuller, of not just louder. The phono input on the Onkyo is very capable but I think a higher input voltage on one of the line in connections will yield better sound. Plus, I've yet to hear anything other than rave reviews for this pre-amp! [ Travers Mar 25, 2017 ]
Price and rating [ John Dec 23, 2016 ]
Best to make sure my music albums are as clear as they ever were. Will work when i up grade my cartridge on my turntable also. [ MIKE Dec 07, 2016 ]
Price and reviews [ R Nov 27, 2016 ]
I have a Pyle pre-amp currently and it does not produce sufficient volume to be any where near the volume of my other components. I find it irritating when one device has to be turned way up just to hear it and then getting my ears blown out when switching to another device connected to the receiver. [ Clifford Oct 28, 2016 ]
Because Jane recommended it, it got good ratings from other users, and it sounded like what I needed for my turntable. Jane's Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=197 [ Britta Sep 04, 2016 ]
price, reviews, Crutchfield reputation [ SIDNEY Jul 08, 2016 ]
pre amp for project turntable [ Donald`` Dec 16, 2015 ]
it was the only one you had in stock at around $100 price point. [ Richard Jul 03, 2018 ]
This device, or one similar to it, is required to connect a turntable to the Sony Receiver I am purchasing from Crutchfield. [ Dale Mar 23, 2018 ]
Someone told me on the internet that it would work well with my SLB202 technics since the phono setting often results in a super low sound. Heres to hoping it'll work and fix the issue. [ Stephan Aug 22, 2017 ]
I choose this item because of its value and technical match for my technics SL7 turntable. [ Ken Jul 06, 2017 ]
Needed a preamp to power the Pro-ject Debut Carbon my wife ordered for my birthday. Almost a complete set! [ YAROSLAV Apr 07, 2017 ]
I needed and amp for my turntable to accommodate a new tuner amp I purchased [ John Jan 31, 2017 ]

wish i could help, steve. but i am not that much of an audio techie. i think i just followed the advice of the crutchfield tech advisory team. [ TERRY Nov 18, 2014 ]
I would suggest the Pro-Ject Debut Carbon (dc). This is an excellent turntable and is a newer model of mine. The dc aspect removes the need of a speed box to stabilize wow and flutter (variances in speed during playback). M/c and m/m refer to your cartridge having either a moving coil or moving magnet. This turntable comes with a pre mounted Ortofon 2m Red moving magnet cartridge. If your system does not have a phono input you'll also need a preamp. Pro-Ject's Phono Box DC is what I use and it's able to be switched from m/c or m/m. Hope this helps. [ JOSH H Nov 18, 2014 ]
The Pro-Ject Phono Box DC is a powered pre-amp that works excellently via an amplifier's "Aux" input. Should be no problem for a bookshelf stereo. [ RONALD Nov 18, 2014 ]
