Frequently asked questions£º
ask£ºDo I need an earphone£¿Is the earphone useful to me£¿Use promotion£¿
answer£ºWhether you need an earphone depends on whether you attach importance to the headset system£¬It`s not whether you can use earphones or not£¡As long as you want to have a good earphone feeling£¬Earphones are essential£¬Especially for those who spent a lot of money to buy good headphones£¬According to the principle of bamboo barrel£¬Consider the problem from the perspective of the whole system£¬Only by grasping the weakest link can we get large benefits with small investment¡£
ask:My headphones are plugged into the sound card orCDmachine£¬It`s already loud£¬Don`t put it in your ear£¿
answer£º
1£ºThe output signal voltage of the sound card is generally200-500mVabout£¬The volume will naturally increase¡£But for the sound quality of the output£¬It doesn`t make sense to be loud£¬Voltage is not the main factor of sound quality¡£
2£ºThe focus of sound quality is to see the current£¬Current output is actually synonymous with power¡£Any analog amplifier circuit has its linear operating range£¬Beyond this range£¬The circuit still has amplification effect£¬It just becomes nonlinear amplification£¬It`s called distortion£¬Or it is called offset jitter exceeding reasonable load¡£So simply loud enough£¬Basically, it has nothing to do with the output quality¡£
ask£ºIt`s said that the high impedance headphones can`t be pushed because of the sound card£¬So you need an earphone£¬My headphones are low impedance£¬I can`t use it, can I£¿
answer£º
1£ºNot recommended¡°hear¡±£¬Try it yourself£¬How many Euro headphones do you plug in£¬Same sound£¬What is immovable£¿
2£ºFor high impedance headphones£¬Its impedance is high£¬Earphones are relatively compatible£¬Easy to put on an earphone casually£¬You can hear the effect immediately£¬So it came out that you¡°hear¡±Fallacy of coming¡£
3£ºActually speaking£¬Sensitivity is the most important parameter of headphones£¬Earphone impedance is not the test of earphone impedance£¬It`s earphone sensitivity¡£Low resistance and high sensitivity headphones are very current sensitive£¬It`s hard to push£¬Need a good enough earphone£¬To really play it¡£And many entry-level low impedance headphones£¬Low resistance and low sensitivity£¬Low sensitivity earphone£¬Effect of upper ear amplifier£¬clear as daylight£¬It makes up for many inherent shortcomings of headphones¡£
ask£ºHow about cooking£¿
answer£ºThe cooker is actually very simple£¬You can turn on the computer when you turn it on¡£computer---USB--DAC¡£openFOOBARplayer£¬Select on output selectionUSBAudio output£¬Then restart itFOOBARCan¡£Headphones don`t need to be plugged in£¬You can connect the power amplifier at the back without opening it¡£FOOBARSelect loop playback£¬So your computer is on,DACIt`s cooking continuously£¬Suggest if possible£¬Stew3-4Close in hoursDAC10minute£¬Then continue¡£DACVery low power consumption£¬You don`t have to worry about the electricity bill¡£
ask£ºWhy did I buy itDACThe new machine feels very different from the one after burning£¿
answer£ºyes£¬Electronic products must need a cooker£¬First, the electrolytic capacitor needs a certain time to activate£¬Other components also need a certain time to operate before the sound can be smooth¡£Analog output of discrete components is used in the earphone£¬So it`s more necessary to cook£¬In fact, you can feel it£¬New machine and cooker50After hours, the difference is very large£¬100Hours will continue to change£¬FortunatelyDACIt`s easy to cook£¬It also consumes little electricity¡£
