User questions & answers

Question:	would this work with the shure sm7b? and do you need a cloudlifter as well
Answer:	should work...needs phantom power....I have no experience with that mic but other reviews mentioned it works with that mic....used with SM57 and Sennheiser 609 where you need some signal boost
Question:	Does it need phantom power? will it work with sennheiser mke
Answer:	The sE Electronics DM1 Dynamite 1 requires 48V phantom power provided by a preamp/mixer/audio interface. It only works with ribbon/dynamic passive microphones and incompatible with phantom-powered microphones such as condenser and active ribbon microphones.
Question:	Can it work for sennheiser ew100 G4 wireless mic
Answer:	No. It works with wired mics only.
Question:	can you hide this or does it have to be plugged straight into the mic? for example I have the shure sm7b and was wondering if it would be seen from it
Answer:	You can connect the sE Electronics DM1 Dynamite anywhere in the chain. You can plug it like Shure sm7b → XLR cable → sE DM1 → XLR cable → audio interface. Please make sure that you connect DM1's XLR cable into a phantom powered microphone input. Otherwise, it might not work or cause damage.

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:	Is the phono input capacitance 100pf or 200pf?　the seller should answer this
Answer:	I'm not the seller. However, it does need a preamp to work with a magnetic phono cartridge.
Question:	Do i i need a better eq
Answer:	Not necessarily. If you’re more recording inclined, maybe. The dynamic range should suffice for most everyday listeners.
Question:	Can i take a regular 3.5 mm aux cord and plug it into the input and take a 3.5 mm aux cord and plug it into the output for my headphones
Answer:	Don't see why not.
Question:	My speakers are speakon so how do i use this amp to run my speakers to run my speakers as a output
Answer:	You need an amp with speakon outputs like the beringer kvm 750. That amp is 750 watt and two channels, you can get it from Amazon for 150.00 . It's a good solid amp with speakon outputs for your speakers.

User questions & answers

Question:	Where is the Input located on this? I only see output
Answer:	Mine appears to be coated aluminum...
Question:	Will this system increase the volume of my phono
Answer:	I have not used a wireless sub of any kind with this unit, but I would be surprised if this worked with a BT sub. The BT on this unit as far as I have read will pair with a device as an “input” to the receiver for audio but will not transmit to an external device. I would not count on using it this way.
Question:	Can the amp wake up from standby when it receives a signal
Answer:	Yes I am driving elac unifi ub5 with this. Kept it on 8ohm but can be switched to 4 ohms if you don’t want to live adventurously
Question:	Does the volume control the output of the line levels, as well as the headphone
Answer:	I just purchased this receiver. N803 and YES, hooked up my EQ. Here is how. 1st depends on how many INPUTS you have on your EQ. Mine has 6. Plug in devices you have into INPUTS you have on back of EQ. Phono, Tape, Tuner, Aux, etc. Device name is only to help you remember what is hocked up. where. You could plug in CD player into Tuner INPUT. It's just a memory thing. Now your OUTPUT on the EQ, hook to the back of your RECEIVER IN LINE 2 OR 3. NOT 1. You need an OUTPUT. This would be like adding a reel to reel to tape to. But you don't have to. [1 doesn't have an output.] I hooked up to [Line2] on receiver. Turn dial on receiver to [Line 2]. Control your devices you want to listen to on EQ, not the receiver. Receiver will always be [Line 2]. this set up allows you, if your EQ has memory to program each device, save the settings from one device to another. Change settings by a push of a button. You get double the punch. EQ plus the base and treble on Receiver. No sub-woffer needed. Good luck, have fun. I am

The OSD Audio preamp provides 4 selectable unbalanced analog RCA inputs: Phono, AUX1, AUX2, and CD/DVD with a ¼” Mic input jack on the front panel, featuring an adjustable mic level control.

KNOBS

The Pre-1’s other front panel variable control knobs feature 3 tone controls: Bass, Mid, and Treble, plus Balance, Master Volume, and Loudness Contour Knobs with Min to Max settings.

CONTROLS

Additional Pre-1 front panel controls include a Power Switch, Tape Loop, Mono/Stereo, Low Filter, and Mute Buttons.

OSD Audio Pre-1 High Definition Preamplifier

OSD Audio’s Pre-1 is a unique preamplifier that accomplishes the subtle audio tasks that takes an ordinary audio source management to the next level. A preamplifier is a low-level amplifier. It takes a line level signal and amplifies it enough to drive the power amplifier to its rated output. If an amp is receiving a signal at its rated output, it will perform better and your surround system will pick up detail you never thought possible.

User questions & answers

Question:	How easy is it to replace the tube sockets in this unit? Some were screwed up on receipt and I may have damaged others replacing tubes
Answer:	Solid state, uses discrete components. Very neutral sounding and has a very open soundstage.
Question:	How many dB of gain can it add to the input signal
Answer:	I've no idea. I gave it away. It wasn't what I needed. It did work fine, but it didn't have a actual On/Off switch which was a bother.
Question:	ax7 tubes are noted for a treble shrillness. is this noticeable on this unit? can the 12ax7 tubes be rolled to lower-gain 12at7 tubes
Answer:	Yes, the RCA out on your tape deck will connect directly into the PA550 and the adjustable treble will give it more boost.
Question:	Can you tell me what size is the pot shaft for the knobs on the front - if I wanted to order nee knobs. This would be the size opening on the backsid
Answer:	Yes, plug your turntable into the PA550 phono input. Plug the output of the PA550 into the input of the SE560 then use the output of the SE560 to go to your amp or preamp. Works perfectly. When first set up, set the level controls of both units half way up.

This electronic preamplifier stands up to the test and will provide you with serious sound performance. The PP999 is perfect for bringing your studio equipment's phono-level output to a more suitable and manageable 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. 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 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 PP999 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 PP999 Preamplifier.

User questions & answers

Question:	If I have a record player without a Preamp, will this help me with hooking it up to a Sonos
Answer:	You can hook it up to anything with a red and white connection. Or if you get the rca to 3.5mm jack then you can hook it up to anything with an input slot. I used this on my realistic lab 440 which doesn't have a preamp. Once I connected the ground from my turntable into the ground slot on this amp, my music sounded loud and clear.
Question:	mp
Answer:	Turntables (with typical magnetic cartridges) have very low signal output (a few thousandths of a volt). Records have the bass reduced to provide enough room on the surface for the recorded grooves, and the treble boosted to reduce the surface noise level when played back. A phono preamplifier performs two jobs: - It boosts the small signal from the turntable by about 50 to 100 times (producing a "line level" signal) so it can be used by typical receivers or amplifiers.- It also boosts the bass and reduces the treble according to an industry standard (the RIAA equalization curve) to restore the signal from the record to its original frequency response.The Pyle PP999 is just an inexpensive phono preamp, nothing special. Phono preamps can range from $20 on up to whatever you're willing to pay for ultra-high quality. Some manufacturers make "USB" phono preamps that have A/D (analog-to-digital) converters built in and connect to a computer's USB port. Most of these provide "CD quality" conversion (16-bits at 44kHz or 48kHz). These may be adequate for digitizing your vinyl, but many computer sound systems can provide up to 24-bit, 192 kHz conversion depending on the software you use (much higher quality), by connecting the preamp output to the computer's line input. Don't just convert directly to MP3 files...you'll lose too much detail compared to the original vinyl sound. It takes almost no time to make an MP3 copy of a high bit-rate WAV or FLAC (lossless) file, but it'll take you an hour to make ANY digital copy of an LP, so do it the best you can the first time!
Question:	So this is a stupid question, I plug my RCA wires coming from my turntable into the Amp. But where do I plug the speaker wires into on the Amp
Answer:	TurnTable==>PreAmp==>Receiver/Amplifier==>SpeakersThe 'Pyle PP999' is the "Preamp". The Turntable is plugged into the PP999 INPUT and the PP999 OUTPUT plugs directly into any (non Phono) INPUT on the receiver. Your Receiver allows you to switch between different music-sources, contains the primary-amplifier and distributes the final sound out to the speakers(and subwoofer). The Receiver should have multiple inputs for receiving signals from eg. CD, Tape, VCR, etc. In my experience those labels are for convenience and interchangeable with the exception of a "Phono" input. NOTE: If the receiver has a "Phono" input then there's a built-in preamp. If your using an external preamp (Pyle PP999) do NOT plug it into the Receiver's 'Phono' input, it could cause damage. I plug the preamp for the turntable into the Receiver's 'VCR' or 'TV' inputs.
Question:	I have the Pyle turntable and Pyle stereo but they don't work together--VERY low sound--so is this the missing piece
Answer:	Turntables (with typical magnetic cartridges) have very low signal output (a few thousandths of a volt). Records have the bass reduced to provide enough room on the surface for the recorded grooves, and the treble boosted to reduce the surface noise level when played back. Most modern receivers DO NOT have the right inputs to deal with this signal (no "phono" input). A phono preamplifier performs two jobs: - It boosts the small signal from the turntable by about 50 to 100 times (producing a "line level" signal) so it can be used by typical receivers or amplifiers.- It also boosts the bass and reduces the treble according to an industry standard (the RIAA equalization curve) to restore the signal from the record to its original frequency response.The Pyle PP999 is just an inexpensive phono preamp, nothing special.
