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.
