Digital Phono USB Preamplifier

With the addition of the PP 4 to your home system, the LPs you cherish the most come alive in the form of expansive and rich sound. Offering superb and measured sonic performance, NAD combines two simple solutions – the PP 4 Digital Phono and the USB Preamplifier – into one small device, making it easy to add phono to stereo amplifiers and AV receivers without a phono input. The PP 4 uses a shielded USB cable and recording level control, which reduces noise and improves the analogue-to-digital conversion process. As part of NAD’s commitment to the environment, the PP 4 features a more efficient “green” power supply that reduces power consumption. It also has an Auto Power Down feature that saves energy by shutting off when not in use.

Digitise your vinyl collection

Offering superb measured and sonic performance, NAD’s two simple solutions, the PP 4 Digital Phono/USB Preamplifier makes it easy to add phono to many of today’s stereo amplifiers and AV receivers that have either eliminated the phono input or included a low quality circuit for attaching your turntable. As part of NAD’s commitment to the environment, the PP 4 features a more efficient “green” power supply that reduces power consumption. The PP 4 goes one step further with a USB interface, shielded USB cable and recording level control which reduces noise and improves the analogue-to-digital conversion process. The PP 4’s Auto Power Down feature saves energy by automatically powering the PP 4 to OFF when not in use.

Our PP 4 Digital Phono/USB Preamplifier enables you to digitise your treasured vinyl collections to a PC or Mac. It features inputs for both MM (moving magnet) and MC (moving coil) types for a wide variety of phono cartridges, and there is a line input to allow for the transfer of cassette tapes. The PP 4 also includes VinylStudio Lite Software for ripping LPs and burning audio CDs. The PP 4 Phono-to-USB Preamp offers a complete hardware and software solution with exceptional flexibility to record from LP or tape.

 

PP 4 VinylStudio Lite

The PP 4 (or the older PP 3) comes with Mac and PC compatible version of AlpineSoft’s VinylStudio Lite ripping software is included with your new PP-4. With VinylStudio Lite you can:

  • Rip LPs into WAV files
  • Split Tracks
  • Burn CDs
  • Record Disks
  • Look up Song Titles
  • Handle File Management

Terrific! Much easier to use than Kongs and my dog loves it.
Flavor Name: Peanut Butter, Size: Medium
I like these so much better than the original Kongs. The large opening makes it so much easier to put peanut butter or cream cheese into it. Plus much easier to clean out afterwards. My dog also likes to chew it and play with it throwing it in the air after he’s done eating the peanut butter. Very sturdy - he chews apart stuffed toys but his chewing hasn’t damaged this at all. I highly recommend this product!

Great for strong chewing dogs. Entertaining too!
Flavor Name: Peanut Butter, Size: Medium
My black lab can destroy the toughest of dog chew toys, but he's not destroyed this peanut. I fill it with peanut butter, yogurt, pumpkin or apple sauce and freeze it. It keeps him entertained for quite a while. When the filling is gone, he leaves it alone or carries it around begging for a filled one.

Super cute! If you have one dog it'll last a while. If you have more than one...buy two.
Flavor Name: Marshmallow & Peanut Butter, Size: Large
This is THE FAVORITE chew toy in our household. We have two grown labs and a 10 month old mutt and they all love this toy. They got a variety of chew toys at Christmas and this is the one that they steal from each other. That said, they've definitely managed to kill it. It's well worth the money and it's held up well to heavy chewers but four months later and we're going to have to buy a new one. It's now a stub. They managed to break off all the marshmallows about a week ago and the stick itself is more like a chunk now but we definitely got our money's worth.

Lasting 6 months in! Great smell.
Flavor Name: Marshmallow & Peanut Butter, Size: Large
This actually does smell like marshmallows which is definitely more pleasant than most dog chews!! It has held up to our power chewer. It’s a bit heavy for our smaller dog but he manages and it’s quite funny!! It’s a bit hard but that’s why it is holding up. Would buy again if this one ever wears out.
