Cards

Term
I/O Module
Definition
parts of the console that address individual signals; adjust the routing and signal levels allowing the engineer complete control
Term
Master Section
Definition
portion of the console where all the global controls are placed; where functions such as listening levels, headphone levels. metering, etc. are found
Term
Patchbay (jackfield)
Definition
set of connectors that allow dorect access to all of the adio signals in the control room
Term
Channel Path (Input Path)
Definition
in recording situations, used to control signals coming from sound source on its ways to the MTR
Term
Channel Path (Input Path)
Definition
in mixing situations, used to control signal playing back from the MTR
Term
Monitor Path
Definition
in recording situations, used to control signals coming from the MTR aloowing it to be heard
Term
Monitor Path
Definition
in mixing situations, can perform many tasks or none at all
Term
Balancing Circuit
Definition
receives the 2 out-of-phase signals coming from the source and "unbalances" them by putting both the high and low signals from the unbalanced line-in polarity w/ each other
Term
Balancing Circuit
Definition
takse inverted signal and reverses it polarity so its in phase
Term
Phantom Power switch
Definition
located in input section, it's used to turn on 48V to service mics connected to preamps
Term
Phantom Power
Definition
commonly used to power condenser mics and some active direct boxes
Term
Pad
Definition
a fixed attenuator used to lower the level of incoming signals
Term
Pad
Definition
prevents overloading and distortion to preamp by lowering the mic signal level before it reachs the preamp
Term
Mic Preamp
Definition
amplification circuit used to amplify the low level output signal coming from mic to a usable "line level"
Term
Mic Preamp
Definition
brings low-level signals from mics to the same level as the console, MTR, and effects processors
Term
Mic/Line Trim
Definition
allows for amplitude adjustment of signals entering the console via the channel's line input
Term
Mic/Line Trim
Definition
adjust for unusual levels on tape, effects processors, or other line level input sources too high or too low
Term
Mic/Line Switch
Definition
determines the input source for the channelpath or I/O module
Term
Direct Box (DI)
Definition
takes signals which are unbalanced and not intended to be connected to a professional console and makes necessary adjustments
Term
Direct Box (DI)
Definition
balances signal THEN corrects impedance so Consumer/prosumer equipment can connect to professional consoles
Term
Fader Ballistics
Definition
number scale alongside the fader; represents how much affect the fader is having on the signal in decibels
Term
Voltage-Controlled Amplifier (VCA)
Definition
amplifier that determine output level and can be controlled remotely
Term
Unity Gain
Definition
point where the fader has no effect on the signal passing through it; considered the optimum fader setting for the highest possible signal-to-noise ratio
Term
Summing Amp
Definition
allows us to combine multiple signals while maintaining the integrity of their relationship
Term
Summing Amp
Definition
combines signals while preserving their relative volumes
Term
Bus
Definition
another name for both the summing amps AND each of the assignments in the routing matrix
Term
Routing Matrix
Definition
allows us to send multiple signals to a single destination, OR single signal to multiple destinations, OR both
Term
Active-Combing Network (ACN)
Definition
a group of summing amps that perform a vital task to multitrack recording
Term
Odd-Even Pan
Definition
pan control feeding the routing matrix
