Power consumption in OFF-mode:
Power consumption in auto standby mode:
Time without input signal until auto-standby: 15 min. (autostandby can be switched off).
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, re cord 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
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.
Output impedance
Term for the AC internal resistance of the driving
signal source, here the preamplifier. The output
impedance of the signal source typically should be
significantly lower than that the input impedance
of the power amplifier. Exception: For power
amplifiers with transmitter input an impedance
matching to 600 ohms is advantageous.
Since between preamp and power amp the con-
nection should be done via coaxial shielded
cables for the best possible reproduction the out-
put impedance should be designed so that the
connected cables do not have disturbing influence
to the signal transmission. Typical cable impedan-
ces are 50 - 75 ohm. The output 2 of the SA-T7 is
designed optimally for this cable types.
