User questions & answers

Question:	Can this be used to amplify the sound coming from microphones in an auditorium (I will be using headphones
Answer:	I very much doubt it. This is a "line level" amplifier. Line level voltage is much higher than the voltage coming from a microphone. This amp is not designed to amplify a microphone.
Question:	Can i sub the power supply for a 12vdc usb cable? would usb sufficiently power this unit
Answer:	USB ports supply 5V, not 12V, so, no, you can't power this thing with a USB cable.
Question:	could this device be bridged like a car amp
Answer:	If you mean could you listen to headphones in the car with this, it is possible if you are a good technician or if your car unit has a “pre” or “pre-amp” output. Trouble is the device has a wal-wart that wants alternating current and concerts it to direct current but you could look around for a CLA with the proper output voltage and tip. So with a pre-amp output, the proper cabling, (rca l/r to 1/4” stereo or trs) and the appropriate power supply this will power headphones in your vehicle. CAUTION: Using headphones while driving is illegal in many jurisdictions- check your state or local traffic codes. This will not drive speakers well by the way... the output power is too low. Good Luck!!
Question:	Are the individual outputs amplified beyond normal "line-level" voltages? In other words, if the input is at max volume, will the output be louder
Answer:	The amplifier circuit has a maximum voltage gain of 10 (20dB). However, the actual gain you can get will depend on the impedance of the headset you plug into any given channel. The design calls for a 47 Ohm output resistor for each channel, but the two I received were manufactured with 470 Ohm resistors installed, so the output impedance was ten times what it was supposed to be. People getting units assembled with this error will see far lower gain than they should. Beware!

User questions & answers

Question:	do the mackie hm-400 bass, treble and balance pots have a detent
Answer:	I dint know. I obliterated have the 4-user version, which does not have any sort of adjustment aside from volume... and there's is no detente.
Question:	Does this work in reverse, i.e., can I plug 4 stereo (line level) inputs and mix them to a single stereo output
Answer:	No, it is one input only, it's not designed (nor will it work) in the opposite direction
Question:	What is the amplification amount of this device? I am going to connect to tv out with low sound level and need to increase the sound output for 2 peop
Answer:	Its definitely enough for two people. I use it to play electronic drums along with music tracks and it works well. Tv would probably require less volume and be equally acceptable.
Question:	Does the mackie hm-4 come with a 1/4" to 1/4" tsr cable in addition to the included 12v power supply
Answer:	Hi, no it comes with HM-4 and the 12 VDC Power Supply, that's all,. Typically manufacturers don't give cables like that since it adds to the cost for them, and many people already have tons of cables. Please let us know if you have any other questions, thank you

User questions & answers

Question:	Does this just split the audio, or does it actually "drive" headphones? If so, how many Ohms can it handle
Answer:	No. This is an 8 channel headphone amp. It simply increases the response of multiple headsets used at one time, to boost the output of each headset in a recording studio setting.
Question:	How do I use this with my laptop? I got male extensions but it doesn't seem to be working
Answer:	We use inputs on the front of the panel and at the same time use some of the ins on the rear panel and it works fine. No issues with volume. Overall a good product for the small amount of money we paid for the item.
Question:	is this just for volume control, or does it actually amplify bass, highs, lows, etc
Answer:	Yes. Just run ear buds with an adapter
Question:	does it come with the extender cord? compatible with M-Audio fast track - cord from the existing headphone jack to amp
Answer:	Hello, to the best of my knowledge, a 220v version is not available in the US. I could not find a specification in the amplifier. A lot of power amps use universal power supplies that allows a voltage from 110 to 220 @ 60 or 50 Hz to be allowed. Usually that specification is marked on the amplifier at the AC input. I don’t see that on the power amplifier images. Hope this helps.

User questions & answers

Question:	can i use this with powered pc speakers to make the splitt more even between 4 sets of small speakers that are powered
Answer:	You want line-level outputs to feed powered PC speakers. Not amplified. That said, it will work, but you would have to keep the output VERY LOW so you don't kill your PC speakers.
Question:	can i use this for using your product in Singapore: Simran SMF-200 Deluxe 200 Watts Step Down Voltage Converter for International Travel to AC 220V
Answer:	Yes but you do not need that amount of potency. Needs 110 to be used with it´s own transformer but you can use a cheaper 220 AC to 12 v DC (negative inside plug) of 200 milliamperes.
Question:	So does this thing pack adequate power to really amplify the sound of my headphones or is it only s mediocre bump in the sound? I need power lol
Answer:	I have an ATH-M50x and I only use half volume of the HeadAmp. It does really amplify the sound!
Question:	can you listen to four separate diff songs through 4 headphones
Answer:	The point of this hardware is to allow 4 to 8 people to listen to one input of a single audio input. To listen to four different inputs you need something like a mixer or the scarlet 18i8

User questions & answers

Question:	What is the difference between a tube amp and a dac/amp combo
Answer:	Not from my knowledge no. There's just an input on the back of the cab. With other cabs it may be possible though.
Question:	Can the line/headphone out be connected to powered speaker
Answer:	Mine did *not* come with a speaker cable. Please note that an 'instrument' cable is needed rather than a regular guitar cable.
Question:	Would this work for the audio-technica ath-m50x headphones
Answer:	It comes w/ jumper cable from head to speaker. Then you’ll need a guitar cable to go from instrument to head unit. I would recommend you buy head unit separate and get a larger speaker than the 8”. It’s loud but doesn’t sound as good as a 10 or 12
Question:	Is this a true 100% tube driven amp? Most Nobsound amps use tubes for pre-amp and use transistor amplification, rendering the tubes useless
Answer:	The head yes but the cab no. It gets really loud but sounds pretty bad through 8” speaker. Buy the head separate and get a 12” cab

User questions & answers

Question:	I bought one of these 2 days ago and it only works when it's halfway into my focusrite solo scarlett gen 3 interface. is this normal
Answer:	That doesn’t sound normal to me. I would check it on another device to make sure it’s not your focusrite that’s defective.
Question:	I bought the 1/4 male to 1/8 female and tried to plug in my apple earbuds but it wont fit. Do I need the 1/4 male to 1/8 female
Answer:	I had to use that in order to plug into my Stereo receiver to connect to regular headphone jack cable. so in short yes, as only a Sony cable plugs into their headset.
Question:	Which adapter should i purchase to use apple earbuds to a ypt-360 yamaha keyboard? would be greatly appreciated
Answer:	Nanyi 1/4 male to 1/8 female connector
Question:	Would this work if I plugged it into my headphones to connect to a microphone
Answer:	This will work on virtually any device with an old 1/4" plug that you are trying to reduce to 3.5 mm. I actually connected a set of old earphones to my AT2020+ mic and it worked fine. One problem: it's about 3" and heavy when assembled. A new device with 3.5 mm connection can be damaged if not careful. For a mic connection I recommend buying a new high quality set of earphones with a 3.5 mm connector.
