Glossary; Input Sensitivity - VINCENT STU-1 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 pre-
amplifier, amplifier or receiver. This includes CD
players, DVD players, FM tuners, cassette players,
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 on the amplifier.
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

signals for amplifier inputs. Inputs on amplifiers
(mostly represented by RCA sockets), which are desi-
gned 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 abbreviati-
on 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
cylindrical-shaped outer lead. This enables a
mono audio signal or a video signal to be trans-
mitted. Compared to the XLR plug connector, this
type of connection is also called "unbalanced
signal connection".
Dynamics
The volume difference between the quietest and
the loudest sounds possible in audio signals, wit-
hout distortion or transition to noise.
