I bought this unit to record the odd track off my vinyl album collection (from my MC cartridge on a Dunlop Systemdek) where I didn't also have a digital copy and it appeared to work ok for such one off use, albeit I found a mismatch between the PP4 and my Yamaha AV amp's phono input such that I had to use an audio level input instead, and even at that, at a higher volume level than I would normally have to employ. However, when I tried to record an entire album, the unit produced heavy distortion and a reducing level after around 16 minutes. Switching the unit off and on, or waiting a few minutes, removed the distortion, only for it to return a few minutes later. On googling for this fault, I noticed reviews on from users who had experienced the exact same issue. I have therefore contacted the supplier (and NAD themselves) with a view to returning the unit and purchasing a preamp (but which one?) from another manufacturer. Shame - when it worked, it actually sounded pretty good. ** Update: Supplier (Silveroaks) agreed to swap out unit in only one day - excellent service, so agreed to give the replacement unit another go. ** update 2: replacement unit working without problems and sounds good into the bargain. Actually made me set up record deck as permanent fixture again.Ī day or so ago I added the note below that starts "I'm not reviewing this as I have yet to purchase it." everything there is still valid except that I have now purchased and had the PP4 delivered. Connecting up was a doddle even if I wasn't familiar with it by virtue of having the similar PP2e already. I have encountered no problems with this device and it does exactly what it should. I have installed "VinylStudio" (full version) and tested that and it also works as it should. So, I'm very happy to recommend this device. Just ensure that as below, you do NOT connect the pre amp to the phono input of an amp. The phono input already has a pre amp and can damage your equipment. Use an aux or other line in input instead. One small point to bear in mind also, it would probably be best NOT to connect the power plug to the mains supply until AFTER you have plugged in the power cord to the device. I didn't and noted a small arcing as a result. I'm not reviewing this as I have yet to purchase it and will do very soon, however I have the PP2. DO NOT connect these to a phono input on your amp. The phono input amplifies the signal which is what the amp does so you are overdoing it. A phono input leads to an on board pre amp so it would further boost the input level. Connect the PP4 to an aux or line input instead. Persons getting distortion when connecting to a phono input, this is your problem. 5 stars is based on the PP2e without the USB facility but it's essentially the same. This is the way these are meant to work and is not a fault. Wie immer pünktlich geliefert und bestens verpackt. Dies vorab.ĭerNAD PP4 ist ein Vorverstärker und Analog/Digitalwandler, um Schallplatten zu digitalisieren. Er verstärkt und entzerrt das Signal eines Plattenspielers mit MM oder MC Pickups, wandelt es in ein Digitalsignal um und stellt es an einer USB-Buchse zur Verfügung. Das aufbereitete analoge Signal wird zugleich auch an zwei Cinch-Buchsen zur Verfügung gestellt. Der Ausgangspegel ist regelbar, die Betriebsbereitschaft wird mit zwei LEDS signalisiert.Īußerdem kann noch ein weiteres Gerät mit Line-Pegel an zwei Cinchbuchsen angeschlossen und mit einem Schiebeschalter gewählt werden.
