True Balanced, Dual Mono & Fully Discrete Audiophile Phono Stage

A New Level of Balance

THE NEW PHONO BOX DS3 B

At Pro-Ject, balanced connections were exclusive to our RS range of products until now. The Phono Box DS3 B model offers some of the high-end features of the Phono Box RS2 at an affordable price and trusted Pro-Ject quality. One of those is our new True Balanced Connection.

High-End Features and Limitless Loading Options

The Phono Box DS3 B employs a steel chassis enveloped by aluminium panels. This construction offers very high rigidity and isolation against interferences, which is essential for the new technology inside. Magnetic wooden side panels are available separately as add-ons. You can connect up to two turntables simultaneously – all parameters for each input get stored in the memory.

Perfectly match the Phono Box DS3 B to a wide variety of cartridges. Load impedance can be set continuously via a potentiometer, a system invented by Pro-Ject Audio Systems, to adjust the impedance during playback and assess the impact of different loading options in real-time. No other manufacturer implements this feature as elegantly!

Balanced By Nature

Cartridges are balanced signal transducers by nature! Due to the internal wiring of MM cartridges, you'll need a MC cartridge to access the entirety of that balanced signal. Together with our new True Balanced Connection cables you'll be able to access high-end features that were previously only available on the most expensive phono stages. And the best: any Pro-Ject turntable with RCA, miniXLR or 5P output can do it!

A TECHNICAL DEEP DIVE

The Phono Box DS3 B incorporates a true, fully balanced gain stage design. Whether you're using a single-ended RCA or balanced connection, both times the fully symmetrical gain stage can optimize the signal-to-noise ratios, feeding the fully passive and discrete RIAA equalization stage with the cleanest signal to work its magic on.

Entirely split passive equalization allows for better impedance matching and lower deviation from the ideal RIAA curve. The Phono Box DS3 B uses fully discrete audio circuitry. A discrete circuit is composed of disparate, individual electronic components, also called discrete components. Years of experience have proven that even the best Op-Amps do not come close to the neutral, natural, dynamic, and vivid presentations of discrete circuit.

TRUE BALANCED CONNECTION

The symmetrical design is the fundamental standout feature! Connect your turntable via the 5-pin mini XLR cable or standard XLR cables and enjoy the benefits of our new True Balanced Connection. A truly balanced gain stage can extract the final musical information, effectively filtering out any noise from interferences stemming from our noisy, modern homes (household appliances, wifi & Bluetooth, power cables, audio amplifiers).

High-End Features

Limitless Loading

Steel & aluminium casework. Entirely discrete audio circuitry. Fully symmetrical gain stage. Split passive RIAA EQ. Dual mono. Balanced in & outputs. Stepless impedance matching.

True Balanced

Unleash the full power

Phono Box DS3 B is ready for our new True Balanced Connection. Single-ended RCA connections, quite literally, only use half of your cartridge's output. With one of our new True Balanced phono cables and an MC cartridge you'll hear details and dynamics, previously exclusive to only the most expensive phono stages.

Great watch, flimsy band
Color: Gray/Lilac
I bought this watch to replace a similar model because the band broke. I see this is a recurrent problem in many other reviews. However, I liked the watch enough to buy it again anyway. I found the new model easy to set, being fairly intuitive. So far it keeps perfect time. I use this watch mainly as a travel watch, and loved the dual time zone function. I am pleased that the newer model now has the ability to set 3 times zones instead of 2, which is an added bonus. The only con I see at this point is the flimsy strap. Unfortunately, the strap on this model is even thinner than on the previous one, and I wonder how long it will last. Also I wonder about the battery length. I think these watches may have been sitting around a long time. The setting showed 2012. I am afraid much of the battery life of the original battery may have already been used up and the battery may need replacing early. Only time will tell. The watch fits my small wrist fine and it is a little more attractive than the old model. I give it 4 stars instead of 5 only because of the band problem.

Fine for a man (with skinny wrists)
Color: Black/Gray, Color: Black/Gray
I have an older mens ironman which has gotten a little beat up and needs replacing. The band is much longer than I need. The metal clasp sits off-center on the underside of my wrist, closer to the part of my wrist which curves around to the front. The too-long strap sometimes flops around and catches on things. I couldn't find a smaller-band mens version, so I tried this "womens" watch (picking the most manly-looking one, of course). I like it better. The band fits my wrist much better, with the metal band in the middle and no flop. I also like that the watch is lighter and the face and band are smaller and less bulky, so it is less noticeable when I'm wearing it (cycling weight weenies will appreciate this). The face is still large enough to be easily legible and contains all of the same great features as my mens ironman watch, plus the newer versions now have an hourly chime, nice! Other info: my wrist is ~17.5cm or ~7.0" around. On this watch, I use the 6th out of 9 slots on the band. On my mens ironman, I use the 3rd out of 9 slots. Weight: this one = 28g, mens = 39g. Pics show comparison of my prior mens ironman with this new "womens" ironman. Photo order is confusing (couldn't figure out how to change that). They are: (1) side-by-side, mens on left, (2) mens band (wider and clasp is off-center on my wrist, end of band hangs over the edge of my wrist -- too long for me -- catches on things), (3) womens band (less wide, clasp is more centered on my wrist and end does hang over edge of my wrist), (3) womens watch (smaller, and looks new), and (5) mens watch, looking a little beat up.

Watch holds up in saltwater!
Color: Black/Gray
I bought this watch to use for my trip to the Galapagos Islands. I read two reviews that the watch does not hold up in salt water. I went snorkeling in the ocean 6 times, about 45 minutes each time. The watch did not leak. I did take precautions by keeping the watch under my rash guard and lowering myself slowly into the water. I also rinsed off my watch each time I snorkeled. I also bought this watch for the multi time zone feature by saving the time on the west coast, east coast and Galapagos time since I cannot change the time on my Fitbit until I land in an airport. I did not use any other features of the watch because I generally use my phone or Fitbit for an alarm or timer. The only complaint I have is that Timex now discourages changing the battery by the consumer. I changed the battery myself on my old Ironman watch. The new Ironman watch is fitted with triangular head screws. So I will have to purchase screwdrivers with triangular heads when it comes time to change the battery.

Reliable and durable, even in harsh conditions
Color: Black/Gray
This watch has served me very well. From Arctic waters to long distance races, it has held up to everything except one task I asked of it, which was my fault. This watch can handle repeated free dives to 12 ft deep. It cannot handle scuba diving at the same depth for an hour straight without needing to have the battery shorted to reset it. It fits well, lights up consistently and brightly enough to read without being blinding, keeps accurate time, and generally does everything I want it to.
