Since , IntraSonic Technology IST has been enriching the residential audio experience by manufacturing robust yet easy-to-use home audio systems. The IST product line offers a premium home audio selection, including music distribution systems, video door intercom systems, and associated accessories.
Envelop yourself "inside your sound" with IntraSonic Technology. Aux outputs are similar to line outputs and are often used to send an additional output from a stereo amplifier or mixing console to a separate recording device. Auxiliary sends are commonly used in bigger mixing consoles. These aux sends allow for alternative mixes within a mixing console and are often used to feed different monitors mixes for different musicians on stage or to feed external recorders.
This means that the audio signals are electrical AC voltages that travel through conductive wires in a cable. That being said, due to the digital nature of many audio devices, there are often analog-to-digital converters immediately at the jacks of both headphone and auxiliary ports. For example, the audio being played within a smartphone is digital and must be converted to analog audio before being outputted from the headphone jack.
This is why they so often get confused. The headphone output of a smartphone or laptop looks the same as the auxiliary input of a car stereo. As mentioned previously, the auxiliary input is designed as a sort of universal plug that accepts various audio sources. The 3. Although headphone jacks vary widely in size and wiring, the 3.
A simple male-to-male 3. There are plenty of 3. Aux outputs have relatively low-level signals that are designed to drive fairly high-impedance loads. Most commercially available headphones have a much lower impedance than the aux out is designed to drive. This will result in a fairly weak signal, and it may be distorted. To get a better understanding of impedance and headphones, check out my article The Complete Guide To Understanding Headphone Impedance. For more information on the sizes of headphone plugs and jacks, check out my article The Differences Between 2.
Aux outputs can be either balanced mono or unbalanced stereo. Aux send line outputs sometimes have a single TRS connector which can be wired as balanced mono rare or unbalanced stereo common. Aux send line outputs may also have two separate connectors for balanced left channel audio and balanced right channel audio.
This brings us to our next point. The aux input is a 3. This allows the aux input to accept stereo signals from other devices with ease. Satellite Radio Integration. Bluetooth Integration.

Generally, the use of these audio ports requires different types of adapters and fittings for backward compatibility as system components evolve from many different manufacturers. The IRQ address is a signal sent from a device to the central processing unit CPU specifying an event, such as an audio signal starting or stopping.
More recently, auxiliary ports and auxiliary jacks became important for the widespread distribution of digital music, through home or car speakers, or directly from a device. So the auxiliary jack and its corresponding port became extremely useful to users.
That is particularly true in the smartphone world, where the single auxiliary jack provides for so many different uses, for example, watching movies or television programming with high-quality audio direct to your headphones, playing music through headphones, participating in conference calls through a headset, etc.
This required the purchase of specialized headsets and other gear that plug in through the lightning port. While defended vehemently by Apple, the move was unpopular with a wide range of users, and remains an example of unanticipated interface problems that are created by the manufacturer. Generally speaking, now that many standard auxiliary reports are becoming obsolete, companies are finding ways to make new systems backward-compatible to older devices, or in other words, to adapt older devices to play music.
New smartphone models have a universal audio port design, at least, they did until the idea of Lightning-port-audio came along. Now, the debate around audio connectivity is a major interest in the mobile device world.
