Input Sensitivity; Glossary - VINCENT KHV-200 Manuel D'utilisation

Audio Sources/Source devices
These are the components of your HiFi system and
all other appliances, whose sound you want to
hear over the system and are thus connected to
the preamplifier, amplifier or receiver. This includes
CD players, DVD players, FM tuners, cassette play-
ers, DAT recorders, personal computers, record
players, portable audio devices and many more.

Input sensitivity

Term for the smallest average (RMS) input voltage
which causes the maximum output power at the
maximum volume setting
Examples: 100 mV to 500 mV (Millivolts) on line
level inputs, 2 mV to 5 mV on the phono MM input
or 0.1 mV to 0.5 mV on the phono MC input.
dB Level
This is a way of describing any physical quantity; it
is a common measurement for signal voltages and
the volume. It is given in decibels (dB). Alternating
signal voltages below 1V (RMS) are described as
"line level" voltages, which are suitable as music

GLOSSARY

on the amplifier.
signals for amplifier inputs. Inputs on amplifiers
(mostly represented by RCA sockets), which are
designed for signals on the CD player, tape
recorder, DVD player etc. are also referred to as
"line level inputs". Those signal inputs must not be
confused with inputs that accept preamplified
signals.
RCA
RCA is the American name for a type of coaxial
connectors and sockets, originally the abbreviation
for "Radio Corporation of America", the name of
a United States company. Both the plug and cable
consist of a rod-shaped inner lead and a cylindri-
cal-shaped outer lead. This enables a mono audio
signal or a video signal to be transmitted. Compa-
red to the XLR plug connector, this type of connecti-
on is also called "unbalanced signal connection".
Dynamics
The volume difference between the quietest and
the loudest sounds possible in audio signals,
without distortion or transition to noise.
