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:	I want to boost my ipod signal to the aux in of a car stereo. will this work for that? it has rca female input jacks on the back of the stereo
Answer:	Yes. Just keep in mind that this booster requires a power source in addition to the input and output cables. The power supply (fits in an ac outlet) is included with the device.
Question:	Can it drive 4 rock speakers from a rheostat connected to my home theater system
Answer:	No
Question:	Hi there, I have svs pb 2000 subwoofer connected to yamaha receiver and the output is way too low, i can barely hear that the sub is there.how do i co
Answer:	Its odd that your SVS pb 2000 (500WRMS 1000w peak) is too low when connected to the output of a yamaha receiver. I have exact same sub connected to line out output of a receiver (all line level outputs are about the same on all receivers) except some are a function of the receiver's volume and others are fixed volume. Either way, when my SVS pb 2000 volume is slightly over half its loud as hell, house shaking. Are you sure you have everything set/connected correctly ? Does your yamaha reciever have a dedicated bass out jack ? Something doesnt seem right. Try connecting to some other line out output on yamaha. Try disconnecting or shut off your main speakers, turn receiver volume to half way and see how loud sub really is. Does your music actually have subwoofer frequency content?? Try some modern rap or EDM music with known loud bass content. Just curious, are your speakers too loud at halfway? Anyway this little amp is extremely easy to connect. Just connect stereo RCA cable out from yamaha to input of this little amp, then connect another stereo RCA cable from output of little amp to subwoofer input.
Question:	How is it powered
Answer:	It is powered by a power adapter (included). It was a good match for my needs.

Product description

The FetHead from TritonAudio is a low-noise, in-line microphone preamplifier that provides improved sound for ribbon and dynamic microphones. The electronics are housed in a metal chassis with a balanced 3-pin female XLR input and a balanced 3-pin male XLR output. It is suitable for use at home, in the studio, on tour, and more. FetHead's circuit uses phantom power but shields it from the input and the microphone's output, providing protection to the microphone. Attach FetHead to a balanced microphone cable and plug it straight into the microphone. Switch on phantom power and enjoy clean gain. This works with any microphone.

User questions & answers

Question:	I have a shure sm57 that tends to be quiet when recording through my usb interface. Will this give a stronger signal
Answer:	Yes, it typically sees an increase of 26Db of boost in Gain. Be sure to drastically drop the input of your interface to where it’s only around 25% - 30% volume. No joke, your mic will be coming in hot. Also make sure your interface has phantom power. Cheers!
Question:	Which end of the preamp goes to the microphone and which end to the cable
Answer:	On all images i saw at online stores, i see that the top end goes to the microphone, & the bottom go to the cable.
Question:	The k6 option is expensive can I used this for the sennheiser instead
Answer:	Currently using it with sennheiser e935 here. It works really great!
Question:	Why does it say it’s for condenser microphones in the description but shows dynamic mics in the pictures
Answer:	The Fethead Phantom is for condenser microphones because it supplies phantom power to condenser mics that need it. The other version of this product, just a plain Fethead, does not supply 48 V. That is the version you would use for dynamic or ribbon mics. Though it may be possible for some microphones to use either one, I would not recommend it. Use the version of the Fethead that is intended for your particular type of microphone, condenser or dynamic. I have both, and I recommend both of them for the appropriate type of microphone. They do a really good job of adding gain with very little to no noise.

User questions & answers

Question:	Can this preamp connect to my active speakers? or just connnect to power amplifier
Answer:	Hi, This is a stereo preamplifier, you can connect it to the active speakers or power amplifier than to passive speakers.
Question:	I have this hooked up to bookshelf speakers, sounds great, would i hear a noticable difference hooking it to a subwoofer
Answer:	I currently use the Pre-Amp with a powered subwoofer amp, it works just fine. The P1 has frequency response down to 20hz, so adding a subwoofer may be worth your while.
Question:	Can i hook this up to a 2 channel receiver? i have a pioneer sx-10ae
Answer:	Yes you can if your receiver has output/input jacks for the Fosi to be in a "loop". If you do not have input/output jacks then you would be relegated to installing the Fosi to cd player or turntable or whatever component you are trying to acquire a bit of tube sound. I use mine to "soften "a bright metal tweeter in my speakers. Since I have separate components it was easy to install in my case. Also check to see if your receiver has "preamp" in/out jacks. This would also allow you to install the Fosi to have a effect on your receiver as well as any other components you have connected to it. A bit of research on your part will be required.
Question:	Is there a recommended replacement tube
Answer:	I replaced the stock ones with the Riverstone Audio 7-Pin GE JAN 5654W (https://www.amazon.com/gp/product/B01BFJDTW0/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1). They are very nice tubes but do need about 20-25 hours of solid burn-in before they start to "warm up the sound" in my opinion.

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. 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 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!

User questions & answers

Question:	I have a 1990 sharp stereo cabinet that has a phono input but no preamp installed. so, i could theoretically plug the preamp into that port
Answer:	I would think if it is from1990 it would still include a preamp phono stage. In any case though, yes it would work if u don't have one built in. Or if u just don't like the sound that comes from your built in preamp u can run this to any other audio in rca jacks on the receiver.
Question:	Would a jensen jta-230 3 speed stereo turntable work with this
Answer:	As long as your turntable has RCA inputs, this should work just fine. Hookup is simple and amplifier is easy to use.
Question:	does this unit have an on/off stwich
Answer:	There is no on-off switch. The unit draws very little power from its wall-wart power supply which would remain powered-up even with the unit switched off. I recommend leaving it on or controlling it along with the other audio equipment. Powering it up while monitoring its output results in a loud "thump."
Question:	how do i know which capacitance option to use (100pf or 200pf
Answer:	You can't "hurt" anything with any of these settings. Of course, you want to use the 'phono' or direct output of the turntable, not the 'line level' or amplified output. just try the 100pf (I think this is more 'standard') and listen for a while. Then try the 200pf setting and see if it sounds better. I think the effects would be mainly small, possibly none.
Question:	Is this what I need to plug an older turntable into a new receiver/amp that does not have a phono jack? When I plug in AUX, there is no sound
Answer:	Yes, you need a preamp to drive the aux channel on your amp. This one work great.
