This document discusses cables and connectors used in audio applications. It covers the different types of cables including straight pair, twisted pair, coaxial, and fiber optic cables. Straight pair cables are used to power speakers while microphone cables use XLR or D-sub connectors. Coaxial cables transmit digital audio signals. The document also discusses balanced and unbalanced signals, various audio connectors, and applications of different cables and connectors in audio systems.

2. Expected outcomes
 Students will be able to understand about the
various types cables and connectors used in
audio industry
 Students will be able to identify different cables
and connectors to be used for specific
application.
 Students will know about various applications
and conversions of audio and video
connectors.

3. Topics Covered in this Session
 Cables and Connectors
 Types
 Uses & Applications

4. Introduction
 When you connect two devices using a
cable, The device that puts out a signal is
called as the source and The device
which receives the signal is called as the
load.
 Cables are group of wires together. They
carry electric signals from one device to
the another.
 Connectors links two cables together to
form a temporary path for the signal to

5. Introduction
 Basically there are 4 types of cables
 1. Straight Pair
 2. Twisted Pair
 3. Coaxial
 4. Fiber optic

In Audio Industry Straight pair cables are used in powering speakers in PA
systems (Live Sound Reinforcement).
Microphone cables either use single channel XLR cables or Multiple channel
cable used in D-sub connectors.
Coaxial cables are used for digital signal transmission digitally from one audio
device to the another.

6. CONSTRUCTION of CABLE
 Audio cables are usually made of one or
two insulated conductors (wires)
surrounded by a wire-mesh shield which
can reduce the hum noise. The shield is
surrounded with a soft plastic or rubber
insulating material.

9. BALANCED AND UNBALANCED SIGNALS
 A cable for a balanced signal uses two conductors to
carry the signal, surrounded by a shield. A cable for a
balanced signal is usually called a balanced line.
 A balanced line rejects hum better than an unbalanced
line, but an unbalanced line under 10 feet long usually
provides adequate hum rejection and costs less.
 An cable for an unbalanced signal has a single
conductor surrounded by a shield. In this case, both the
center conductor and shield carry the signal.

10.  Connectors are part of cables; they are called cable
connectors. Other connectors are built into equipment
chassis; they are called chassis connectors.
