Pro-Ject Tube Box DS3 B (Black)

In Stock	An In Stock item is available to ship normally within 24 business hours.
Preorder	A Preorder is an item that has not yet been released. Typically the label will set a projected release date (that is subject to change). If a projected release date is known, we will include this in the description in red. Other Preorders are set to release 'TBA.' This means that release date is yet 'To Be Announced'. The Preorder can be released anywhere between weeks, months or years from its initial announcement.
Backordered	An Out Of Stock item is an item that we normally have available to ship but we are temporarily out of. We do not have a specific date when it will be coming.
Awaiting Repress	Awaiting repress titles are in the process of being repressed by the label. No ETA is available at this time.
Expected On	When an item is Out Of Stock and we have an estimated date when our stock should arrive, we list that date on our website in the part's description. It is not guaranteed.
Special Order	A Special Order item is an item that we do not stock but can order from the manufacturer. Typical order times are located within the product description.

Description

Following the long-term success of the Tube Box S2 and Tube Box DS2 comes the incredible new Tube Box DS3 B True Balanced phono preamp.

The Tube Box DS3 B features both single-ended RCA and Balanced XLR inputs along with single-ended RCA and Balanced XLR outputs. For best results, connect a moving coil cartridge via the Balanced XLR input and then connect the Balanced XLR outputs to your Balanced system. The RCA and XLR inputs feature separate memory for setting the impedance, capacitance, gain and subsonic filter.

Both outputs are always active, so you could even run a local system via the RCA outputs, then run long XLR cables to a remote system. This is a perfect solution for distributed audio systems when you want the turntable in a convenient location.

The best part is that Pro-Ject still thinks value is an important element to consider when designing a new product. The Tube Box DS3 B retails for just $1,099, so another class-leading performer! Order for delivery soon!
