Microphone Level, Instrument Level, Line Level, Speaker Level

Microphone Level

Speaker Level

Line Level, Consumer (-10dBv) is 0.316 volts, Professional (+4dbu) is 1.228 volts

Speaker level to mic level (radial)

Can convert Mic level to line level

They are transducers that use electromagnetic induction.

A device that converts sound signals to electrical signals into sound., When sound waves hit a thin diaphragm causing it to vibrate, The diaphragm is attached to a coil that is surrounded by a magnet

Creates a magnetic field around the coil., Sound waves move the coils past the magnet and create an electrical current., Creates sound Signal

Dynamic Mics

Condenser mics

Output really low levels, need amplification to boost signal, It is possible to boost the gain by 50 - 90 db of gain, Does not require phantom power

High Output and requires less amplification., They have Amplifiers built into them to help with proper levels preamp(head amp), They require phantom power, Less durable

Adjust the volume and tone of input audio signals., Most of the control knobs and faders are arranged on the top panel, it is easy to understand the signal flow and what state the audio is in., Operating analog mixers is normally an intuitive process

Process input audio signals and adjust their volume and tone using digital signal processing technology, Various kinds of tone control that would be impossible using analog equipment can be applied using digital processing., Can store the positions of faders and knobs, and recall these positions in an instant., will require more experience to set up effectively, but will offer far greater functionality than an analog mixer., have all the signal processing on board including, EQ, compression, effects, graphs, as well as scene templates, recording options, output processing, automation, and more.

They are analog mixers with built-in power amplifiers., Sound can be played with the mixer directly connected to speakers., Can be used by simply turning the power on, so operation is simplified and convenient., These are non-professional mixers and are typically seen in coffee houses, and small conference rooms., They offer limited functionality and typically include a small number of inputs with fixed EQ, a small graph, a couple or outputs and on-board effects.

Microphones, DI Boxes, Passive DI Box, Active DI Box, Line level input sources

Convert unbalanced high z signal to balanced low z signal.

The term "passive" indicates that the unit does not require a battery or other power source to operate., Less expensive passive DI units are more susceptible to hum, and passive units tend to be less versatile than active., They cannot include preamplifier features which enable the user to boost the gain.

Contains a preamplifier. Therefore provide gain, and are inherently more complex and versatile than passive units., Requires a power source, which is normally provided by batteries or a standard AC outlet connection, and may contain the option for phantom power use.

Such as playback machines (computer interface, media players, other mixers)

They are devices that amplify electrical signals that have been adjusted to an appropriate volume and tone sent from the mixer., Varying in size, shape and output power, which are suited to different situations.

Active, Passive

Easiest to deploy with built-in amplifiers that are matched to the speaker components., Woofers, mid-range, tweeters, compression drivers, They only require a line level input and you won’t have to use separate amplifiers to power them., Require power from cable or Batteries

Require amplification, speaker cables, and may require an outboard crossover and other signal processing, Some will utilize an internal crossover network, which functions like the active speakers., You’ll need to look at the specification sheet by manufacturer to determine correct amplifier

Passive 1

A single speaker, or multiple speakers placed far apart, broadcasting a full range of sound from a single point

A single speaker radiates sound in a spherical pattern and therefore has less range.

Features a number of identical loudspeakers arranged in a vertical line., Allows sound waves to constructively interfere with each other so that they can send sound waves farther than single source loudspeakers, in a directional path.

Allows frequency response and clear sonic coverage throughout the range of the system., Suppression of the high frequency output and the physically time-shifted outputs from the individual speakers.

is a rugged metal housing used in the audio engineering and entertainment fields to connect microphones and other sound equipment to the multicore cable., Functions as an extension of the equipment cables, allowing for the sound desk to be situated further away from the stage., Sometimes referred to as an audio snake or simply Snake

Typically come in 2-wire, 3wire and on occasion, 4 and 5-wire., XLR Male and Female, TRS (Tip ring sleeve)

2-Wire: Signal (+) and shielded common., 3-Wire: Signal (+), Signal (-) and shielded common., 4-wire: signal (+), signal (-), common and shielded ground, 5-wire: 2X signal (+), 2 X signal (-), and shielded common (ie/ StarQuad

XLR Male - Connects to various hardware inputs., XLR Female- Connects to the Mic and various hardware outputs.

Connects to both input and outputs.

Ethernet audio expansion port with locking EtherCON connecter supporting multiple AoIP protocols, Provides access to 64x64 digital channels, Connected over a single cable ‘digital snake’ and allowing remote preamp control to mixing systems

The signal being produced from the microphones or equivalent devices such as a direct box., This is the lowest level mentioned, Requires preamps to raise levels to next stage. Between 0.001 volt and 0.10 volts

The level output of keyboards, sample pads, etc., Voltage approx 0.6 volts

The highest signal before amplification and is produced via pre amps., There are 2 variations called Consumer (-10dBv) is 0.316 volts and Professional (+4dbu) is 1.228 volts

The Highest voltage used and are post amplification., Speaker level range is wide. Can go as high as 100 volts
