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.

Basic everyday napkins but very thin
These are about as basic as paper napkins get. They work fine for everyday meals and quick cleanup, but they are definitely on the thinner side. You usually end up needing more than one for messier foods or larger spills because they don’t feel especially absorbent or heavy-duty. That said, the large count is convenient for everyday household use, cookouts, lunch packing, or casual gatherings where you go through napkins quickly. Overall they’re functional budget napkins, just nothing particularly thick or special.

Bake and Take - Excellent for Large (or small) Gatherings!
Size: 25 Pack w/ Lids
I ordered these 9 x 13 foil pans specifically for a trek to Mom's on Mother's Day. I chose them because they included the covers, are disposable, reusable and the best way to transport a warm meal to a family gathering. I have 8 siblings. I made pans of enchiladas for each family unit. Particularly in this current health situation - even among family members, the separate portions minimizes contact with others' food. Each pan was perfect for 18 chicken/cheese enchiladas. I made 10 pans for the entire family. I also ordered smaller pans (8.4 x 5.9) from this seller so each sibling could take some enchiladas home. The lids sealed perfectly; the pans were sturdy. I also used the small pans to make croissant crème brûlée custard - each person enjoyed their own portion of dessert – they all ate right from the pan – how convenient is that? I could not be happier with this amazingly convenient way to 'bake and take' - and NO WASHING PANS! I rolled into the gathering like a caterer - my family was really impressed. I intend to bake and take - AND bake and stay (again, NO WASHING PANS!) I made a large salad to consume during the week. I made it in the large pan and popped it in the fridge, easy peasy. I plan to use these pans for bar-b-ques. They’re great for marinating before grilling, taking the meat off the grill and placing into the pans AND, they are the ‘serving platters’. I highly recommend these pans (and the seller – I received them wicked fast!)
