Gain Staging and Analog Output Levels
Application Note Gain Staging and Analog Output Levels This paper seeks to clarify questions regarding analog input audio from one place to another, a digital system—regardless and output levels when using digital transport systems and of its manufacturer—is comprised of multiple active electronic how these devices can be used effectively for a range of circuits (at minimum, one at input and another at output). The applications. devices in a digital snake should be thought of as additional circuits in the signal chain—along with the mixing console, mic preamps, effects processors, DSP, amps, and so on. Looking At LeVeL ACroSS the SignAL FLoW Some users have connected their system and then asked why In all of these devices, there is no expectation that the input there’s “signal loss” from analog input to analog output. Com- signal and the output signal match, and the industry is full of ing from a world of largely lossless analog wires, users expect gear with input and output specs that are different from one to see a signal move from one place to another without much another. Unfortunately, input and output level specifications change in level. are not standardized. But it’s essential to remember that, while both analog cables and digital snakes perform the same basic function of moving Source Destination Output +4dBu Input Source A typical analog signal path using copper wire Destination Output +4dBu Input This diagram above shows a typical analog signal path using nation device—no processing occurs in the copper wire con- copper wire.

An Audio Amplifier Is the Heart of a Sound Reinforcement System in a Classroom
Best Practices for Selecting Classroom Amplifiers An audio amplifier is the heart of a sound reinforcement system in a classroom. The amplifier takes the line level signal produced by the source device, amplifies and distributes it to the speakers throughout the room. It is important to note that an amplifier will only be required for speakers that are not self amplified. Self amplified speakers will typically have line level audio inputs, such as RCA or 3.5mm. Speakers that require an audio amplifier will typically have speaker wire connection as inputs. Selecting the proper amplifier helps to ensure that the audio system performs to its maximum potential. There are many factors that must be considered when selecting the proper amplifier for an installation. Size of Room The size of the room is one of the most obvious considerations when selecting an amplifier. An amplifier that is designed for a typical classroom, typically 90ft2, would not be appropriate for an auditorium that is 900ft2. One of the main differences between the amplifiers for these different size rooms is the power output. For a typical classroom a power output of 40 to 50 watts is more than sufficient, whereas an amplifier with a power output of 500 to 1000 watts is better suited for an auditorium. While it is possible to use an amplifier that has more power than is needed within a classroom, this would incur an unnecessary expense. Audio Inputs The audio inputs on an amplifier are an important consideration because they impact the ease of installation. Many classrooms now integrate a microphone system for the teacher, in addition to a separate audio playback source such as a DVD or Blu-ray player. -

Audio Electrical Wiring Considerations Basic Branch Circuits in Homes And
EELE 217 Science of Sound 2017 1 Audio Electrical Wiring Considerations Basic branch circuits in homes and businesses (U.S.) Service Panel Black Wire ("hot") Circuit Breaker (from power company and White Wire (wide) power meter) (neutral) (narrow) Ground Bus Bar Green or Bare Wire Cold Water Pipe (protection ground) IF the outlet is wired correctly (never EVER risk your life on this assumption!!), the white wire ("neutral") should be the wide blade and the electrical potential should be near zero potential. In the U.S. the black wire ("hot") is 120 volts RMS (root-mean-square) sinusoid, 60 Hz repetition frequency, with peaks ±170 volts respect to the neutral. Keep in mind that the colors are purely customary: the color itself doesn't influence how the electricity flows in the circuit! The green (or bare) wire is the protection ground, and the internal wiring of an appliance will have this conductor connected it to the metal chassis of the appliance. The green wire does not conduct any current under normal circumstances, EXCEPT if there is a fault in the appliance that allows the "hot" wire to come in contact with the chassis. In the case of a fault the ground wire short circuits the "hot" wire through the chassis and back to ground, which should draw enough current to trigger the circuit breaker to open, de-energizing the outlet. This protection is important, because without it a fault could energize the chassis, and then a person could get shocked by simultaneously touching the chassis and a nearby grounded surface, inadvertently completing the circuit. -

How to Choose the Right Cable
Choosing the Right ProX Cable for Your Needs Unbalanced vs. Balanced Cables First thing to know about microphone cables, XLR is a CONNECTOR, not a cable although often called an XLR cable incorrectly. A more correct description would be “Audio Cable with XLR”. A balanced electrical signal runs along three wires: a ground, a positive leg, and a negative leg. Both legs carry the same signal but in opposite polarity to each other. Any noise picked up along the cable run will typically be common to both legs. Assuming the destination is balanced, the receiving device will “flip” one signal and put the two signals back into polarity with each other. This causes the bulk of the common noise to be out of phase with itself, thus being eliminated. This noise cancellation is called “Common Mode Rejection” and is the reason balanced lines are generally best for long cable runs. XLR Audio and TRS cables are used to transmit balanced audio from one balanced device to another. If you are experiencing noise on a balanced cable, it could be caused by incorrectly wired cables. Unbalanced cables are less complicated, but they’re much more susceptible to noise problems. In general, unbalanced lines should be kept as short as possible (certainly under 25 feet) to minimize any potential noise that may be carried with the signal into the connected equipment. Understanding Common Cable Connectors In the audio world, there are six common cable connectors you’ll come across frequently: TRS and XLR for balanced connections and TS, RCA, SpeakON, and banana plugs for unbalanced connections. -
