Seems to be working just fine. I like the fact that this has the ability to switch from MM to MC at any time in case of an upgrade or something. Reasonable price.

Pro-Ject Phono Box DC

David from Providence, RI on 4/10/2017

Crutchfield Customer Review (What's this?)

Great little preamp! Since I now use a Sonos Connect and B&O active speakers, I have eliminated my integrated amp using this and a $20 switch box. The Sonos box already eliminated my tuner.

Pros: Great price performer. Works with both MM & MC.

Cons: None so far.

My record collection comes alive again!

Pete from Phoenix, AZ on 4/5/2017

Crutchfield Customer Review (What's this?)

I am happy to report that my Pro-Ject Phono Box DC arrived very promptly from Crutchfield and I was able to install it very easily. My Marantz SR 6004 stereo receiver has no phono input jacks and so this Pro-Ject Phono Box absolutely "fills the bill" allowing me to once more access and play my LP record collection, allowing me to hook-up my turntable to my Marantz receiver. I played several records on my turntable, hooked up to the Pro-Ject Phono Box DC, and they sounded terrific through my Marantz and main family speaker system. I'm delighted with this Pro-Ject Phono Box and would recommend it highly to anyone in my similar situation. Also, the moderate price is another big plus. Kudos to Crutchfield for carrying this really fine home audio product.

Pros: Compact size, easy hook-up, great sound from my records, and moderate price.

Cons: None at all!

Easy as pie

Peter from Alameda, CA on 1/24/2017

Crutchfield Customer Review (What's this?)

This unit is very simple to connect. Turntable to preamp, preamp to receiver, plug into AC outlet. Done. They should make everything this simple. Can't compare how well this works as compared with other preamps, but no problems with this one.

Pros: Simple to connect

Cons: An expensive addition if you are buying a new receiver that doesn't have a phono preamp built in.

Pro-Ject Phono Box DC

John from Conifer, CO on 1/17/2017

Crutchfield Customer Review (What's this?)

This provided a great way to add add my '80's Pioneer turntable to my Adcom GFP-750 preamp that lacked a phono preamp. It supports MM and MC cartridges and is small enough to sit on the shelf behind the Adcom.



Easy install, works well.

Kurt from St Augustine, FL on 11/28/2016

Crutchfield Customer Review (What's this?)

So far, so good. Easy to hook-up, and it's small enough to hide w/o too much trouble.

Pros: Neat and clean, well made.

Cons: No on/off switch to conserve energy or indicator to let you know when it's powered up. Not a big deal, but add in a house full of low voltage consumers and it becomes an issue over time. Still would have bought it, though.

Project Phono Box DC

Rod from Virginia Beach, VA on 7/27/2016

Crutchfield Customer Review (What's this?)

I purchased this after buying a new AVR that had no phono input stage. The Pro-ject Phono Box allowed me to continue to listen to my vinyl on my Rega turntable and sounds great. Just connected it to an unused analog input on my receiver and it sounds incredible. Highly recommended!

Pros: Ease of use. Price.

Cons: None

Small & mighty

Chris from BROOKLYN NY on 5/22/2016

Crutchfield Customer Review (What's this?)

Quality little brick of a phono amp. Works great with my vintage Technics by Panasonic 1300 TT.

Pros: No lights, 2 cartridge phase choices.

Cons: None so far.


Jimmy from Tifton, GA on 4/11/2016

Crutchfield Customer Review (What's this?)

Basic building brick piece for stereo. Dead quite with a small footprint. Drop dead easy setup. Everything you would think a brand matched power supply should be, which means this is the last time I will ever think about it.

Pros: Small, black

Cons: Does not come with ice maker

Just what the doctor ordered!

The perfect solution to mating an older ProJect analog turntable to a current Pioneer AVR - worked like a charm!

I purchased an Onkyo mini system and asked Crutchfield's advisor Jasan about hooking up my turntable to it. Jasan suggested the Pro-Ject Box and a cable for connection.; Easy hook up and works flawlessly now I can listen to my "records".

Pros: Good product.

HumboldtRick from Eureka, CA on 4/2/2014

Crutchfield Customer Review (What's this?)

Needed to integrate my old Denon turntable with my new HT system. Works well and looks good. The MM/MC switch is on the back which could be inconvenient in some situations, but isn't too much of an issue with me.

Pros: Works well Looks good

Cons: MM/MC switch are on the back of the unit

Phono Preamp

John S from Blue Bell, PA on 12/24/2012

Crutchfield Customer Review (What's this?)

wanted to connect ~20 year old high quality turntable to new receiver without a phono input. Had a moving coil cartridge pick-up. Very easy to set up. Works great. No problems and you won't need the instructions. Volume output of pre-amp/receiver in phono mode matches comparable CD input.

Pros: offers moving coil and moving magnet pickup option. Easy to set up

Cons: none

Missed my vinyl

PBDave from Pittsburgh, PA on 11/4/2012

Crutchfield Customer Review (What's this?)

Because of a move, major remodel and then purchase of my new Denon receiver with no phono input I hadn't listened to my albums for over 3 years. Kyle suggested the Pro-Ject Phono Box DC for the necessary preamplifier. It took minutes to connect and figure out how to operate my turntable with my Harmony One which is a miracle since I am techno-inept. I listened to album after album and was blown away by the sound through my ancient Klipsch Heresy speakers. All of the things vinyl nuts say about the fullness and warmth of sound were so evident I was truly a bit surprised. I never duplicated my albums with my CD collection s so I am having a literal blast (apologies to my townhouse neighbors) getting reacquainted.

Pros: Mindless installation even for techno-inept Clear, full, distortion-free sound from my vinyl

Cons: None I can think of

Hands-on research

Product Research


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)

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 ]

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 ]

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 ]

1 question already asked

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 ]
