How To Set Up A Headphone Amp
A headphone amp is the best solution to optimize the power supply and audio quality of your headphones or in-ear monitors. But how exercise you lot connect a headphone amp in the most efficient mode? How practise y'all connect all the sources already associated with your hi-fi amplifier? Is it possible to connect your calculator or smartphone to it? Notice out how to properly connect a headphone amplifier to your equipment to relish the best possible listening experience.
Why use a headphone amp?
The headphone output built into amplifiers or CD players normally works fine, just it is frequently the poor relation when designing these devices, especially entry level models. Interference can degrade the sound betoken, especially if the distension of the headphone output is not isolated from the master excursion. For example, the operation noises of a CD player's disc drive tin be transmitted through the headphones. With amplifiers, the power supply is liable to create disturbances in the signal. Thus, whatever the qualities of the headphones used, it is possible to improve their musical operation by associating them with a headphone amplifier. The latter also has the reward of better managing impedance variations betwixt dissimilar headphones, especially the more than demanding ones that require a off-white corporeality of power to deliver their total potential. A headphone amplifier therefore allows yous to benefit from better dynamics and optimized tone reproduction. Enough to make the most of a pair of high-end headphones.
How to connect a headphone amplifier to a how-do-you-do-fi amplifier
If you have an existing hello-fi system, all your sources are probably already connected to a hi-fi amplifier. Then how tin yous bask these sources on both your how-do-you-do-fi amplifier and via your headphone amp, without having to constantly unplug each device? For this purpose, many stereo amplifiers offer 2 solutions: a pre-out and/or a REC output.
If y'all connect the headphone amplifier to the pre-out, the hi-fi amplifier will act every bit a pre-amplifier. In practice, you will be able to adjust the volume from both the hullo-fi amp and the headphone amp. This configuration tin be very user-friendly when your headphone amplifier does not accept a remote command, as you can then hands control the volume remotely with the stereo amplifier's remote command. Nonetheless, care must be taken to keep the output level close to that accepted by the headphone amplifier's input so as not to generate distortion. For this reason, it is often preferable to connect a headphone amplifier to the REC output of an amplifier, as the latter has a constant line level. There is therefore less hazard of distortion and the book tin can only be adjusted from the headphone amplifier.
Whether the headphone amplifier is connected to the REC output or pre-out of a hi-fi amplifier, it is better to employ a high-quality RCA cable such equally the Norstone Arran RCA to maximize the signal transfer from your unlike sources. Notation that depending on the electric installation, the association of a headphone amplifier can cause a ground loop problem resulting in unwanted noise from the speakers and headphones. In this case, information technology is necessary to isolate each element using a galvanic filter such as the Oehlbach Sound Linear 8.
How to connect a headphone amplifier to an AV receiver
The headphone output of A/5 receivers is oft of poor quality. The employ of an external headphone amplifier is often essential to relish the best sound quality. To connect a headphone amplifier to an AV receiver, the best solution is to use the receiver'south Zone 2 output. The level of the latter tin can commonly be set to stock-still or variable. As with how-do-you-do-fi amplifiers, it is best to opt for a fixed level to maximize the performance of the headphone amplifier. In addition, using the Zone 2 output allows you to enjoy an output that is contained of the rest of the A/Five receiver, making information technology possible to listen to your music through headphones while someone else is watching TV.
How to connect a headphone amplifier to a figurer
Information technology is possible to connect a headphone amplifier to a computer using a mini-jack to RCA cable such every bit the Audioquest Gilt Gate mini-jack RCA cable. Although practical, this solution is not the most efficient, because the music is converted and largely amplified past the figurer's sound card. The latter is often of poor quality, even on high-end computers. It is therefore best to use a headphone amplifier that has its ain DAC and a USB input. Such models include the Cambridge DacMagic 200M, iFi Audio Zen Dac and iFi Sound iDSD Neo iDSD. Using a cable like the NorStone Jura USB A>B, you can then connect the amp to the figurer'south USB port to bypass the sound card entirely. Using software such as Foobar or Audirvana, this configuration also allows you to savor How-do-you-do-Res music and DSD files that your reckoner cannot decode and read without losing information. An Sound DAC with a headphone amp office is therefore a sure manner to savor the best music quality possible.
If your headphone amplifier is entirely analog and you even so want to enjoy optimal sound quality with a figurer, you tin can add a USB Sound DAC like the Micromega MyDAC. The latter has a USB-B input to support the conversion of music played from your reckoner. The headphone amplifier is and so easily continued to its analog RCA output.
How to connect a headphone amplifier to a smartphone
For the most office, the latest smartphones aren't equipped with a mini-jack output to allow you to connect a pair of headphones or in-ear monitors. Fifty-fifty if some notwithstanding feature this output, it is often of average quality and its power is insufficient to power demanding headphones. It is therefore condign increasingly common to have to connect a headphone amp to your smartphone to use hi-fi headphones in the best possible conditions. To practice this, the connectedness is very similar to that used for computers. Consequently, you demand a headphone amplifier with a USB input or a USB Audio DAC. The required cable, yet, varies from one smartphone to another. For Android models, you lot need a USB-C to USB-B cable similar the Audioquest Forest USB-B to USB-C, while Apple tree smartphones require the Apple Lightning to USB adapter.
For mobile use and to enjoy the qualities of your hi-fi headphones or IEMs when traveling, it is possible to pair your smartphone with a portable audio DAC or a portable headphone amplifier. The latter also connect to the smartphone'southward USB port, the only difference existence that they are more meaty to fit in your pocket and exercise not need to exist plugged into the mains. Some models such as the Astell & Kern PEE51 are no larger than a USB wink drive and are powered directly by the smartphone. More energy-intensive models similar the iFi Audio hip-dac integrate their ain battery and then every bit not to impact the autonomy of the associated device.
