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:	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.

User questions & answers

Question:	How well would this work with 6 ohm bookshelf speakers
Answer:	It would work. I’m using 8 ohms right now and I tried 4ohms also and it worked.
Question:	Does it have a connection for a powered subwoofer
Answer:	Most subwoofers have speaker level connectors. You connect all four speaker wires out from the amp into the sub and then there are four connectors to go out to the speakers from the sub. Then you can set the pass through levels on the subwoofer for the optimum sound you want. The sub handles the low tones and passes the higher tones on to your speakers. It works great. Plenty of tutorials on youtube and such.

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:	How do you format this and why is that necessary for new drives? What stops me from plugging it right into my system and getting started
Answer:	Depends on what you're doing. You can connect this to your system but new drives will not be functional until you initialize them and create a partition under Disk Management. Your other option (what I did with this drive) is to disconnect your existing drive and then install this (while PC is off if that's not obvious). Then you have a blank drive in your system and can boot from an OS disc like Windows 10. A fresh Windows 10 installation will still recognize the drive and be able to initialize it properly as well as create the necessary partitions. Let me know if you have any follow up questions.
Question:	Hi i have questions how the better samsung evo 970 or wd black 250gb high-performance nvme pcie gen3 8 gb/s m
Answer:	Reviews have suggested that the two drives are VERY close in performance (nearly within margin of error of tests). The WD Black gen3 devices were the first ones to actually challenge the 960 EVO NVMe drives for dominance of the high-performance consumer grade SSDs. You can't go wrong with either one, as far as I can tell, at least from reviews. They'll provide insignificant differences in speed/performance between the two. Therefore, you should purchase based on price and (if it's important to you) warranty. Note also that the WD drive caps at 1TB in size (vs. 2 TB for the 970 EVO), so if you wanted to go that route, there's only one choice. As far as "best high-performance consumer level" NVMe drive, the 970 EVO and the 3rd generation WD black are on an even playing field, and both at the top of the stack (this ignores the "prosumer" market devices like the 970 Pro where prices are much higher per gigabyte). Note that it's possible that you won't notice any performance difference between these high-performance NVMe drives and, say, a high-quality SATA drive.
Question:	I want the 2 TB, is it possible
Answer:	If you find someone with TB, you can have as much of it as you want!
Question:	Whats the difference between this one and the 960 pro
Answer:	The 960 Pro is from the previous generation. The newer one is the 970 Pro. Comparing the 960 Pro to the newer 970 EVO is a bit difficult because they aren't in the same class. The Primary difference between the Pro and the EVO is the Pro uses MLC (Multi Level Cell) whereas the EVO uses a Triple Level Cell. Case and point with the EVO. You can get a 2tb EVO drive but the Pro tops out at 1tb. The silicon is able to get more storage space for the real estate with TLC. On the other hand MLC is more reliable and more hearty than TLC which is why the Pro is using the MLC. Maybe you want to know about write endurance. One thing to keep in mind about write endurance is you will probably never come close to hitting it's limits unless you are using the drive all the time to save and load large files like a professional would. Also, the write endurance of the 1tb 970 Pro is double the write endurance of the 512gb 970 Pro. hardware review sites and done tests of the actual write cycle longevity of these drives and these drives last longer than what they're rated for. More than likely in your case, these drives will be long obsolete by the time they're half worn out. The write endurance of the 500gb 970 EVO is 300TB write cycles. Sequential R/W of the 970 EVO is 3400MB/s read and 2300MB/s write. I believe the 970 evo uses a Single Level Cell cache to boost write speeds. The write endurance of the 512gb 960 Pro is 400TB/wc. Sequential R/W of the 960 Pro is 3500MB/s read and 2100MB/s write The 970 series is more refined. Both use the updated Phoenix controller whereas the 960 series uses the Polaris controller. Both the 960 Pro and 970 EVO have a 5 year warranty. The older 960 EVO only has a 3 year warranty. The answer to this question between the 960 Pro and 970 Evo is simple........... get whichever is cheaper.

Product description

Geddy Lee has been performing without onstage amps and speakers since the Test for Echo Tour in 1996, favoring major household appliances instead. Known for using a variety of gear to create interesting layered tones, Geddy has included the SansAmp RBI and/or the SansAmp RPM in his rig since 2001. Wanting to streamline and simplify his gear for new projects, Geddy partnered with Tech 21 to design a signature SansAmp, the GED-2112. This challenging collaboration involved distilling a rackload of equipment into a single rackspace. It resulted in a new format for Parallel Pre-Amping - having two separate internal pre-amps that run in parallel. https://youtu.be/wpAqJyRYYVE

• Blend to adjust the ratio of SansAmp tube amp emulation and your direct signal
• Deep pre-amp has dedicated -inch and XLR direct outputs
• Drive control for gain and overdrive
• Dual, all-analog SansAmp circuits
• Effect Loop with Mix 50/50 switch

Question:	Is there a headphone jack on this sansamp
Answer:	I have mine routed through 2 channels on my board. Yes, you can run both the deep and drive channels at the same time.
Question:	How do you hook it up
Answer:	Desolder the leads, remove the two mounting screws and remove the socket. On that model inserting the tubes can be difficult due to the inexpensive sockets. When inserting the tubes put your finger under the socket in order to put a bit more pressure on the tube as you are inserting it.
Question:	What is best way to run unit innto a bass amp
Answer:	I have no way to measure the dB gain but I’ve run the power amp with and without the preamp....it’s a very noticeable boost but not enough boost to run a TT without a cartridge preamp
Question:	Is this a power amp and if so how many watts
Answer:	Just get some RFT 12Ax7 tubes, you'll have more warmth than you will ever want. Just get Shuguang or the Preferred series tubes made for TheTubeStore.com by Shuguang. Pretty warm that you can more than warm up enough with other 12au7s. You have to think and plan with tubes, not plug n play.

User questions & answers

Question:	I want to use this for my Audio Technica M50xs. Worth it
Answer:	Yes
Question:	What's the Difference with the E10K & E10? I loved my E10 but it's starting to fail, so I'm looking for a new one
Answer:	Yes, unfortunately.
Question:	What outputs does it have? I see only one headphone out (small jack). Does it perhaps have RCA in the back
Answer:	I have mine connected to my headset and the back is connected to my speakers. Sound will play from both if you have both devices on
Question:	so you plug this in any usb port and voila?, how do you eq
Answer:	That's what I use the Dragonfly (Black) for. I expected a subtle improvement, but found it to be night and day! The cheapo DAC and output stage circuitry that's built into the laptop was really limiting the sound quality.

User questions & answers

Question:	can you use a pop socket with this case
Answer:	there is no headphone jack
Question:	Does this case fit iPhone 11 mini
Answer:	It comes with instructions - you have several options on hook up along with dual output applications.
Question:	Are those little X all over the case
Answer:	Sansamp actually included an option to sum (mix, add) the 2 channels to 1 channel. Drive and Deep become mixed together and the output of the Drive and Deep output jacks is the same. It takes about 5 minutes and a screwdriver, is easy, and is reversible. I found instructions online you could search for, in short, you remove the bottom panel and swap a jumper. There are two jumpers, the other affects the mute switch to become a bypass. Sansamp says it voids the warranty, so I'd get a guitar tech or electrical buddy to help maybe. Another option, when you are not pretending to be geddy lee, is to use only the output of the drive channel. The drive channel is actually just a sansamp RPM, a discontinued, sought after preamp. Great product by the way, it's got geddy's name on it, but I find that I can use it for anything.
Question:	Does it have a raised bezel to protect the screen, and if so what are the measurements of the raised bezel
Answer:	No. It is not a power amp. It is a pre amp designed to shape tone. You will need an amplifier or you can run it directly to a mixing board. Plug your bass into this, then plug this into your amp or board and adjust tone to your liking. Very versatile pre-amp.

User questions & answers

Question:	Will this work with a Sony a
Answer:	Probably depends on the pop socket. If it can’t stick to silicone (or other flexible material), it might not stick well to this case.
Question:	How could I install a monitor on this
Answer:	Unlike iPhone 12, they don't call any of the iPhone 11s a "mini." This is for the iPhone 11 (not the 11 Pro, which is smaller than this phone, and not the 11 Pro Max, which is bigger than this phone.)
Question:	What is the difference between style I and II
Answer:	The little Xs are only on the back of the case.
Question:	How do I connect the two tubes together
Answer:	It's slightly raised above the front edge all the way around, not quite 1/16 of an inch. Enough, if dropped flat onto a flat surface, the screen itself wouldn't hit. But it's not a screen protector like for scratches or for an uneven surface like a gravel driveway or something like that.
