DCM – MVP Dual Chain Module
Destination – A category or type of electronic component designed to receive a signal and project
it to the listener/viewer. (e.g. video monitors, Speakers, etc.)
Equalizer – An electronic component that divides a 2 channel signal into typically 5, 7 or 9
frequencies and allows the user to adjust the amplitude of these frequencies to the
desired levels.
Equalizer Amplifier – An Equalizer designed to receive a 2-Channel or 4-Channel low-level or high-level
signal, then process and amplify that signal to a four channel high-level output
signal.
Fade – To balance the front and rear attenuation.
Fader – A control that balances the front and rear attenuation.
Floating Ground – Having left and right signal grounds isolated and electrically different.
High-Level – A signal that does not require amplification to be heard through Speakers. Also
referred to as Speaker level or active.
High Power – A high-level signal that is typically greater than 6 watts.
Input – Where a signal enters a component.
Line Level – A non-amplified signal. Same as Low-level, Passive, and Preamp Level.
Low-level – A non-amplified signal. Same as Preamp, Passive, and Line Level.
Low Power – A high-level signal that does not require amplification that is typically 6 watts or less.
Output – Where a signal leaves a component.
Passive – A non-amplified signal. The opposite of Active.
Passive Component – An electronic component designed to receive and output a low-level signal.
Passive Equalizer – An Equalizer designed to receive, process and output a low-level signal.
Position – A set of 2 channel (R+ L+ R- L-), high or low-level connectors on a Switching Module
where components are connected to the Matrix System
®
and assigned selection
numbers.
Preamp Level – A non-amplified signal. Same as Low or Line Level, or Passive.
Process – To modify a signal by adjusting the amplitude of certain or all frequencies.
Processor – An electronic component that receives a signal at its input and modifies the signal
before it passes through the component’s output.
RCA Connector/Cable – The type of male and female connectors used with low-level signals.
RF Level – A video signal that in a sense is “amplified”. Typically transmitted at the 75 ohm or
300 ohm level with coaxial cable.
