Equipment CABLES AND CONNECTORS CABLES AND CONNECTORS

Mini Plug - 1/8 in. TRS Plug

The worst audio quality. The choice of modern audio players and consumer

electronics. This type of audio connection typically offers a decent

signal for no-professional applications. TRS in the name stands for Tip, Ring, Sleeve. The number of rings tell the

user if the plug is stereo (two rings) or mono (one ring).

Phono Plug - 1/4 in. TRS Plug

A better alternative to the mini plug. This type of connection is used by professionals yet isn’t the preferred

connection. Widely used in the music industry to connect some

microphone applications, connect speakers, amplifiers, and guitars this plug has an inherent flaw. It

can easily be unplugged. The number of rings also tell how many

channels the cable is capable of handling.

Canon XLR - Female End

The best audio quality. The choice of profession

applications. This type of audio connection typically

offers an analog signal.

Canon XLR - Male end

The best audio quality. The choice of profession

applications. This type of audio connection typically

offers an analog signal.The button at the top of the

connector prevents the cable from accidentally

being unplugged. The cable cannot be removed without

pushing this button.

Canon XLR port

This port is used to connect XLR cables to a device. In

this application a Microphone is plugged into this location.

MIDI Port

This is a MIDI port. The MIDI plug allows for input of musical notes

from electronic instruments into a computer.

RCA Phono port

This is a RCA Phono Port. Notice that the port is color coded. The red typically is right and the white is left channel audio. In this application a red and white RCA cable was used

to connect a digital signal input and output.

Phono Plug - 1/4 in. TRS Plug

This port connects phono plugs to a device. In this

application the left and right audio monitor

channels are output.

RCA Plug

This common audio and video connector has been around since the 1940’s and is still

used in modern electronics. It was originally used to connect record players to amplifiers.

Today it is used in many different applications but isn’t the preferred connection for

high quality video and audio. The longer the cable the

greater the chance of interference.

6 & 4 pin Firewire cable plug

The most common way to connect digital audio and video to a

computer. It has been adapted to audio applications. The cable has very fast data transfer rates and is

often used to connect portable hard drives. The term Firewire is a brand name from Apple Inc. and is known internationally as IEEE 1394 High

Speed Serial Bus. The four pin connector is the smaller inset

image.

A & B Type USB Plug

This type of connection was designed to allow universal

connection between multiple devices.USB stands for Universal

Serial Bus. The connection is used for cameras, audio devices, and

data. It is the most commonly used computer connection in modern

computers. The inset image is also a USB plug it is a B Type plug.

B Type USB Port

This plug is used in an audio application. It connects an audio board to a computer. It is also used to connect a computer to many many

things.
