what is a dac?

modern includes an electronic component dac (digital to analog converter). a dac’s job is to convert digital audio data into a low voltage signal that can be amplified by an amplifier.

analog components, like a cassette deck or turntable, don’t require a dac; already output low-voltage analog signals. but digital audio devices like smartphones, tablets and ipods need both a dac and a headphone amp to be able to hear sound through your headphones.

what do headphone amps do?

an amplifier can be added between your player and your pair of headphones to improve clarity, detail and dynamics.

Headphone impedance rating is something you may be familiar with. the combined resistance and reactivity of the headphones to an amplifier acting as an electrical load is called impedance.

  • high impedance headphones require more voltage to achieve a solid listening level. it’s an excellent choice for portable players with limited internal battery voltage.
  • low-impedance headphones may have a lower damping factor and draw more current. an amplifier can improve the sound quality of low-impedance headphones.
  • an amplifier may be warranted depending on the size and dimensions of your pair of headphones. in-ear and in-ear headphones are generally very efficient and won’t benefit from an amplifier.
  • an amplifier will make larger headphones sound clearer and more natural. Some audiophile models may require an amplifier to achieve desired volume and sound quality, especially if connected to portable devices.
  • Headphone amplifiers with internal digital-to-analog converters (DACs) may improve drastically your quality of music listening experience if you have a tablet, computer or laptop.

use a line out port on your portable device to connect to headphone amps. if there is no line output, you can use the headphone jack to send the audio signal to the amplifier.

computer audio only

Although many people enjoy listening to their headphones on their computers, let’s face the fact that they’re not as good as you’d like. computers will convert digital files to analog, which is usually as cheap as possible.

a new generation of amplifiers allows you to connect your computer via usb cable to this amplifier. the amp will come with dacs that are better than the ones in your computer. some even resynchronize the incoming signal to improve timing. you can know more.

there are two types. the one will have a usb connector that plugs into the usb connector on your computer. the other will have a standard headphone jack and can control the volume through the computer. you will need a usb cable to connect the other type of component. the front of this guy will have volume control and a full size headphone jack.

the usb connector feeds the amplifier which is connected indirectly. you can connect the amp to your smartphone with the correct adapter cable for much better audio on the go.

multiple audio inputs

These amps will include usb audio input to a computer or smartphone, analog audio output or digital sound. some models may have both a digital and analog input.

Headphone amplifiers with multiple audio inputs can be portable or battery powered. These amps have a great section for headphone amps and can drive a power amp or power a pair of powered speakers.

every component in your system can be connected to the amplifier that provides the switching. you can also use amplifiers with additional audio outputs that allow you to drive an amplifier or a pair of powered speakers. this will help you build a small but great sounding system and improve the performance of your headphones.

how to connect a headphone amp to a hifi amp

You probably already have a hi-fi system. this means that all your sources are connected to a hi-fi amplifier. how can you get these sources into your hi-fi amp, as well as your headphone amps, without unplugging them all? many stereo amps have two options for this purpose: a preset or a record output.

  • the hi-fi amplifier will function as a pre-amplifier if it is connected to the pre-out. in practice, you’ll be adjusting the volume of both the hi-fi amp and the headphone amp.
  • This arrangement can be extremely convenient if your headphone amps don’t have a remote control. you can control the volume remotely using the stereo amplifier’s remote control.
  • To avoid distortion, it is important to keep the output level within the limits of what the amplifier can accept. it is better to connect a headphone amp to the rec output of an amp since the latter has a constant level. volume can be adjusted from the amp alone, and there’s less chance of distortion.
  • to maximize signal transfer between your sources, whether the amp is connected to the recording output of a power amp hi-fi or to the pre-amplifier of a hi-fi amplifier, it is best to use a high-quality rca cable.
  • Electrical installation may affect the ability to associate a headphone amplifier with the rec production. this can cause unwanted noise in the headphones and speakers. it is important to isolate each element with a galvanic filter.

connect to an av receiver

Poor quality headphones are often emitted by a/v receivers. for the best sound quality, an external amplifier is often required. The best way to connect an amplifier to an AV receiver is to use the receiver’s zone 2 output.

you can configure the output as fixed or variable. To maximize amplifier performance, the volume should be set to a fixed level. the zone 2 outlet also allows you to have an independent outlet, allowing you to listen to your music while watching TV.

connect to a computer

A mini-jack cable can be used to connect a headphone amplifier and a computer. this solution, although practical, is not the most efficient. the computer’s sound card converts and amplifies the music. even on the most powerful computers, the latter can often be of poor quality. a headphone amp with its own dac is best.

This setting allows you to play high resolution music as well as dsd files. your computer cannot decode or read these files without losing any information. the feature can be added to an audio dac, allowing you to have the highest quality music possible.

You can still enjoy the best sound quality using a computer. this dac supports converting music from your computer via a usb-b input. then it can be connected to the analog output rca.

connect to a phone

Latest smartphones do not have a minijack output that allows you to connect headphones or internal monitors. although some smartphones still have this output, the quality is not great and there is not enough power to power the headphones.

  • To use hi-fi headphones at their best, you’ll need to connect a headphone amplifier to your smartphone. the connection is similar to the one used for computers. you will need a usb audio or usb input amplifier to do this.
  • however, the cable required will vary from smartphone to smartphone. Headphone jack sizes come in different varieties, as do headphone amps. You will need an apple lightning to usb adapter, which is required for android models.
