Line Input
This is an input that is designed to operate at Line Level.
Line Level
This is the nominal or operating level of an audio system. This level normally corresponds with a '0 VU' meter reading. Standard Line levels are:
+8 dBm (1.95 volts RMS), Broadcast
+4 dBm (1.23 volts RMS), Pro Recording
-10 dBv (310 millivolts RMS), Alternative Pro Recording
Line Output
This is an ouput designed to operate at the nominal Line Level.
Loss
This is completely the opposite of gain in a circuit, i.e. attenuation.
Low Pass Filter
This is a type of filter that attenuates frequencies above a cutoff frequency. i.e. it allows low frequencies to pass through unchanged.
