Comparison M-AUDIO M-Track Solo vs Behringer U-PHORIA UM2

The type of line input provided in the device. Uses the line input to feed audio from an external source to the audio interface.

The following types of connectors can be used for line input:

— mini-Jack (3.5 mm). A socket for a standard mini-Jack plug (3.5 mm). The connector serves as an audio input for two stereo channels. It is designed primarily for portable electronics such as smartphones, pocket players, etc. In stationary devices, Jack (6.35 mm), XLR and RCA are more popular.

— Jack (6.35 mm). A common audio connector for transmitting an analog signal. In design, this type of socket is as similar as possible to a mini-Jack (3.5 mm), but differs in size. Jack connector (6.5 mm) provides tight contact and is less susceptible to interference. It also supports a balanced connection - high-quality transmission of audio signals over fairly long wires with effective protection against interference.

- XLR. The XLR standard is considered professional - not only because of the high quality of signal transmission, but also because of its fairly large size and the presence of locks for securely securing the plugs. However, only one channel of audio can be transmitted over one cable, so XLR outputs are usually installed in pairs - based on stereo sound. Also note that these connectors can be combined with Jack sockets (6.35 mm). They also allow y...ou to implement a connection in a balanced format with a high degree of noise immunity and the use of fairly long wires without affecting the frequency of the analog signal.

- RCA. Connector for coaxial cable with tulip type plug. The standard RCA input consists of two jacks - for stereo sound, left and right channel. One analog RCA connector can only transmit one channel of audio, so the number of such connectors corresponds to the number of channels supported by the device.

— Total audio outputs Jack / XLR. The total number of analog audio outputs such as Jack (6.35 mm) and/or XLR (this interface can be combined with a “jack”). Note that such connectors can play the role of both the Main output and the linear output. For more details, see the relevant paragraphs.

— mini-Jack. The standard 3.5 mm mini-Jack is usually used in audio interfaces as an analog (line) output for two stereo channels, as well as as an output for connecting headphones (see the corresponding paragraphs).

Through the Main outputs it is supposed to transmit signals from the audio interface to external devices for playing and recording sound. In everyday use, there are models with one type of Main connector, as well as with several varieties (for example, Jack (6.35 mm), XLR, RCA, or Jack (6.35 mm) / RCA, or Jack (6.35 mm) / XLR).

— Jack (6.35 mm). Output for transmitting analog audio signal. Structurally similar to the popular mini-Jack, but differs from it in its larger dimensions. As a result, Jack type plugs (6.35 mm) are used primarily in high-end stationary audio equipment. Outputs of this type usually operate on a “one channel per connector” principle (i.e., to transmit stereo sound you will need to use two Jack sockets). Also, this interface often provides a balanced connection - a connection in a special format that allows the use of long wires without compromising the signal quality (due to the suppression of interference in the wire itself). However, the Jack connection (6.35 mm) may also be unbalanced.

- XLR. Another type of output for transmitting an analog signal using a balanced connection. It allows the use of long cable lengths without compromising the quality of data exchange - external interference is absorbed directly in the cable. Often the connector is combined with a Jack interface (6.5 mm). The XLR is equipped with a locking lock and three contacts. A single three-pin an...alog cable can only carry one channel of audio, so a standard XLR output typically consists of two jacks, stereo left and right.

- RCA. Jacks for coaxial cables with characteristic plugs, popularly known as “tulips”. One cable in analog format can transmit one channel of audio. The standard output of this type consists of two connectors - for the left and right stereo channels. On the other hand, RCA does not provide the possibility of a balanced connection, which is why it is inferior to other options in noise immunity, has noticeable limitations on cable length and is poorly suitable for professional use. Nevertheless, “tulips” have become very widespread in entry-level and mid-level stationary audio equipment.

The type of line output provided in the audio interface design. It outputs a line-level analog audio signal. This interface is mainly used for connecting recording devices, outputting a signal to playback equipment or to an external amplifier. And the types of connectors used for linear output can be as follows:

— mini-Jack (3.5 mm). A standard socket for the popular mini-Jack plug (3.5 mm), used as a line output. This connector is mainly used to connect some models of active speakers, while two stereo channels are usually output through one mini-Jack (3.5 mm). Note that headphone outputs, which also use a mini-Jack, are considered separately - see the corresponding paragraph.

— Jack (6.35 mm). A larger analogue of the mini-Jack connector (3.5 mm) for outputting an analog stereo signal. The Jack output provides a more reliable and noise-free connection, making it ideal for professional applications. Effective protection against interference is possible with a balanced connection method. To save space, the 6.35 mm output can be combined with an XLR connector (see the corresponding paragraph). The disadvantage of this design is the impossibility of using both interfaces simultaneously. Jack line outputs (6.35 mm) adhere to the “one channel per connector” principle.

- XLR. A round three-pin connector for outputting a line-level analog audio signal, oft...en with a balanced connection type. Transmission is carried out over three wires instead of two, and during it the noise induced on the wire is eliminated. This allows the use of fairly long cables without compromising the “purity” of the signal, making this type of connection excellent for professional audio equipment. XLR is also considered a professional interface, both due to the ability to work with a balanced signal and due to increased reliability: such connectors are often equipped with locks to secure the plugs.

- RCA. Analog linear audio output using RCA connectors - so-called “tulips” (due to the characteristic shape of the plugs). The standard output of this type consists of two connectors - for the left and right stereo channels. Also note that RCA connectors can be used in other output interfaces, but they have their own names.

The device has a separate output for connecting headphones. Most often, its role is played by the classic mini-Jack connector (3.5 mm). However, there are models with several outputs. They, along with mini-Jack, can use other connectors. Headphone connections serve a variety of purposes - some devices actually act as high-end external headphone amplifiers, while others allow you to control the sound sent to the outputs.

The software included with your audio interface may vary depending on the make and model. The vast majority of it is represented by drivers, utilities for managing the device, software for recording and editing sound, virtual instruments or effects, and all kinds of plugins. It is advisable to clarify separately which specific software components are included in the audio interface package.
