Product description

This electronic preamplifier stands up to the test and will provide you with serious sound performance. The PP444 is perfect for bringing your studio equipment's phono-level output to a more suitable line-level output. It'll take your audio signal, amplify its strength and prepare it for further processing by your receiver or amplifier. Preamps technically provide voltage gain to your desired equipment and are key to assisting the signal source, whether it's a turntable, musical instrument or microphone. The ultra-low noise audio conditioning circuitry allows the preamp to boost audio to levels that are more manageable for various types of audio equipment. You'll find it easier to adjust the recording level volumes of different sources from microphones and instruments alike. You should position your preamp close to the source to reduce unwanted noise and interference. Preamps can sometimes come built into the stereo equipment, but if that's not the case, the PP444 is an easy install, wise choice and great addition to any musician or producer. Take your sounds and audio production skills to the next level with the PP444 Preamplifier. Features: Converts Phono Signals to Line Level Signals State-of-the-Art Circuitry Accommodates Magnetic Pickups Ultra-Low Noise Operation Improves Sound Performance Connects to Turntables and Other Studio Equipment Input Sensitivity: 3mV at 50K Ohms (Phono) Dedicated RCA and 1/4" Output Connectors Output: 2V max (P-P) at 10K Ohms DC 12-Volt Power Adapter Included Frequency Response: 20 Hz ~ 20 KHz ±2dB S/N Ratio (A-WTD): 70 dB - Output Level: 2V THD: 0.08% @ 1KHz and 3mV Input | S/N Ratio: 70dB Input Sensitivity/Impedance/Phono 3 mV/50K Ohms Load Impedance: 10K Ohms - Reference Voltage: 1V d Dimensions (W x H x D): 3.54" x 2.13" x 1.02" Sold as: Unit Weight: 0.85 lbs.

User questions & answers

Question:	Does this thing have an/off switch or do you need to plug/unplug everytime you use it
Answer:	no switch. You can plug/unplug, I leave it plugged in all the time.
Question:	Unit works fine for awhile and then starts outputting static, even with no input connected. I've tried it with several amps with the same results
Answer:	Most likely people who are having noise problems it is because of ground loop isolation problem. If you have a ground loop isolation problem grounding the preamp box is unlikely to help. Without getting technical, what you want to buy is a ground loop isolator or a humm eliminator; both the ground loop isolator and humm eliminator tackles the cause of the noise at the fundamental source of the problem, depending on your audio setup, one maybe easier to use than the other. To use the ground loop isolator or the humm eliminator they generally come with instructions, or you can google this topic. If the noise in your audio system isn't fixed by using this solution the first time, try putting the ground loop isolator and humm eliminator at various points in your audio system. Also you can talk to audio people and get advice about how to fix ground loop problems from people who setup big audio systems, for concerts and such; if you talk to the average electronic garage shop audio enthusiast you are likely to get bad advice, i.e., meaningless explanations. Also caution must be used when Googling this topic, much of the discussion, advice and explanation on this topic is bogus, you can get a general correct feel of this topic if you read a number of explanations. Also one more thing that can cause a "popping noise" is that you have too much gain, this is a phono amp and the gain is huge, it takes a 3mV and makes it 2Vp-p this is a gain of around 100 to 200, if you gain up the audio signal too much then the signal out of your amplifier runs out of head room and clips, this can cause a popping sound, essentially you have too much gain. If this is occurring you need to either buy a preamp with less gain or attenuate the signal before it gets to the preamp. If this is a problem, too much gain, you can buy preamps with gain control.
Question:	My turntable has very quiet output. Will this device help boost the volume
Answer:	Yes, indeed. If your need was like mine (no built-in pre-amp on the turntable and no specifically dedicated phono input on your amplifier) you will find this unit to be the perfect solution to needed amplification of the turntable's output. Don't forget to hook up the ground wire as directed or you may wind up putting unwanted noise into the audio.
Question:	My amp DOES have a Phono Input, but my cartridges are low output. Can I use this to boost the signal using the Phono Input to reduce audible hiss
Answer:	No, you can't. This is a phono preamp with RIAA playback equalization that amplifies the signal about 100 times, so it essentially does what your built-in phono preamp does. The output signal from the separate preamp is equalized to a nominally "flat" frequency response and the amplified signal level will overload and probably damage your built-in phono preamp. Plug it into any other stereo line input on your system (AUX, CD, DVD, TAPE, VCR, etc.), but NOT the PHONO input! If you need higher signal gain, maybe look at phono preamps from ART or TCC that have output level controls. If you use moving-coil (MC) cartridges, you need a preamp specifically designed for them...they require at least 55 dB (over 500 times) signal gain vs. about 40 dB (100 times) for moving-magnet (MM) cartridges. Noise becomes a critical issue with MC cartridges because of their extremely low signal output, so good-quality cables and good turntable grounding are essential.

User questions & answers

Question:	How much gain does this preamplifier have? Thanks
Answer:	A preamplifier's purpose is to enable a user to play a turntable through an amplifier (or receiver) that either does not have a phono input, meaning a left an right RCA jack (and many newer amplifiers do not have phono input in rear of unit), or if you want to use two turntables with the amplifier and the amplifier only has one phono input. Thus there is no "gain." Only regular amplifiers have a "gain." It is NOT a waste of money if there is no phono input for the turntable. It is actually NECESSARY in such case.
Question:	I think i have mc tt. it has line level out but missing riaa eq. is this what i need to get bass back into the music and tone down the harsh treble
Answer:	You asked the right question about equalization(and level matching) because m/m requires one circuit ,and m/c requires another. Your existing gear determines what you need .You must verify your cartridge type,picking m/m is a lazy fall back. Yes a m/m circuit will often carry a m/c signal but at a poor sound quality pass through,reduced signal, reduced response. Many dubious preamp sellers use a single fits all cheap m/m circuit claiming it covers both because of that. Then like myself you will find your $450 Audiotechnica MkIII suddenly SOUNDS LIKE CRUD. That said if you have m/m already your set,and thats fine then your matched up. When you get good with test equipment you can seee a difference when a pre amp has both dedicated circuits instead of scamming m/c users.
Question:	Will this substitute the main amp device on a Panasonic console if I just want to hear the turn table and nothing else
Answer:	No it's a pre amp for stereo that doesn't have a phono input. It's not a stand alone amplifier.
Question:	when connecting a turntable to a phono preamp/preamplifier dodoes one connect the rca jacks from the turntable to the output or the input on the pream
Answer:	The signal path is 1# energy out of the turntable (record player) 2# into the preamp (preamp's in) 3# out of preamp -preamp's out- into receiver ,amplifier, or etc the device your going into.
