Product Research

Features

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)

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 ]
A
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 ]
A
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 ]
A
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 ]
A
I still have a turntable. [ Kenneth W.  Jul 26, 2017 ]
A
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. [ Switchkat  Jul 21, 2017 ]
A
Good reviews. Crutchfield reputation. Great Crutchfield assistance with making selection. [ Kent  Jul 13, 2017 ]
A
Larry's recommendation and the reviews. [ JEFFREY P  Jun 16, 2017 ]
A
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 ]
A
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 ]

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 ]
A
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 ]

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 ]

Can this Pre Amp be used to connect a Music Hall USB 1 turntable directly to a powered sound bar? Thinking of hooking up to Kiplisch 48" sound bar. Would like to do away with current receiver.

It is technically possible. You should reach out to one of our advisors for more personalized help in exploring the required cables and such for this application. https://www.crutchfield.com/support/ContactUs.aspx
[ Calvin  Jan 08, 2020 ]  Staff
A
I would be happy to help, but I just don't know the answer to the customer's question. I the sound bar can accept line out from a receiver, I don't know of a reason that it would not accept line out from a preamp. But then maybe my unserstanding of sound bars is not current. best, Richard
[ Richard  Jan 08, 2020 ]
A
Sounds possible. My turntable is connected to this amp, and then the amp connected to powered speakers. So similar, but not the same
[ NANCY  Jan 07, 2020 ]
Q
I have a shelf system and would like to add a turntable. M/m, m/c I don't know which to get. Or even DC. Can you help?
[ steve  Nov 17, 2014 ]
3 answers
A
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 ]
A
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 ]
A
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.
