2Technical highlights
2.1 Philosophy
The ideal amplifier is perfectly load stable, 100% level and phase accurate, and
has no long signal paths. It should not use tricks like over amplification and very
high negative feedback to achieve good results in the lab but poor sonic perfor-
mance in the listening room. The stereoamplifier 711 combines extreme speed with
an ultra wide bandwidth (1MHz/-3dB) and a high current capability far beyond that
of valves and output transformers. A unique and sophisticated circuit design opens
up sonic qualities once considered incompatible: precision, velocity, stability and
power.
2.2 Layout
Throughout, the stereoamplifier 711 is designed as a consistent dual-mono layout.
Both left and right channels feature identical audio amplifiers, each with its own
high efficiency power supply. The layout is optimized towards shortest signal paths.
For minimal losses the stereoamplifier 711 has massive copper rails for all high cur-
rent signal paths.
2.3 Amplification
From the input the stereoamplifier 711 first buffers the music signal. A high per-
formance correction amplifier is then used to capture and correct any deviations in
the signal, very quickly and very precisely. Ultra wideband amplification using no
feedback loops follows, a less than 10 nanosecond transit time and level accuracy
to within 0.1dB ensuring signal purity. The whole is housed within a sealed module,
maintaining a common temperature across all stages to further guarantee precision.
The output stage comprises 14 power transistors per channel, all mounted onto a
massive copper rail which is temperature controlled for a constant quiescent cur-
rent. The 711‘s impressive low level signal handling is reflected in its raw power de-
livery. Current levels of 60A and more are readily attainable.
2.4 Power supply
The supply of the amplifier section is based on modern switched mode power sup-
plies. Four modules with 600VA each optimized for audio application combined
with audiophile capacitors (>1’000’000 microFarad) provide enough power reserves
even for the most demanding music signals. Circuitry that does not process audio
signals should not be able to influence them. That’s why we use no less than 5 ded-
icated power supplies for the ancillary stages.

User manual
Follow the safety advices
Keep this user manual.
Mains supply
Exclusively use 3 phase power cords with ground conductor.
Unplug the 711 from the mains in the following cases:
before you manipulate with cables
before cleaning
during thunder storms
before you leave for longer periods
Cabling
While manipulating with cables the 711 has to remain discon-
nected from the mains. Wrong cabling may cause damages to
your 711, amplifier and loudspeakers. Excessive volumes due to
inappropriate handling may cause hearing damages.
Transport
Use only with the cart, stand, tripod, bracket or table specified by
the manufacturer or sold with the apparatus. When a cart is used,
use caution when moving cart/apparatus combination to avoid in-
jury or tip over.
Packing
In order to omit condensation of water inside your stereoamplifier
711, let it warm up within the packing.
Please keep the original packing for future transports.
Operation
Never run your stereoamplifier 711
with opened housing
with closed cooling-slots
with high ambient temperatures (>40°C)
close to heat sources like radiators, etc.
with extremely high humidity for example in humid cellars
close to water (Sink, bathtub, or similar equipment)
Cleaning
Use a soft and dry towel. We suggest using a nonabrasive microfi-
ber towel. Please do not use any solvents or liquidities
Service
Service by a qualified person required if
the mains-cable or the mains connectors are damaged
foreign substances or liquidity have entered the 711
the 711 has seen rain
the 711 seems to malfunction
the 711 has fallen to the floor or the housing is damaged

5.1 Mains (A)
The stereoamplifier 711 does have no mains switch. As soon as connected with the
mains it will be in operation mode OFF (<0.5W consumption)
5.2 Input (B)
Please use top grade audio cables. For longer connecting cables we suggest using
the balanced inputs.

7Protection functions
Comprehensive protection functions ensure safe operation and a long lifetime. The
stereoamplifier 711 has the following protection functions:
Level limitation:
For to high levels at the input of the stereoamplifier 711 the soft clip circuit is acti-
vated. The activated soft clip circuit will distort the output signal significantly, the
sonic performance is reduced. Please ensure that the input levels are within the
limit of 1.8 Vrms.
Overcurrent:
If the output current to the loudspeakers exceeds 80 A the stereoamplifier 711 is
switched off automatically. This represents a maximal impulse power rating of ca.
4’000 W (50 V @ 0.6)
Overtemperature:
The temperature of the power transistors is permanently monitored. If the maximal
operating temperature is exceeded despite of active cooling system the stereoampli-
fier 711 is switched off automatically.
Fuse
The mains connection has a fuse which protects your stereoamplifier 711 against
too high power consumption. Please replace with the same fuse type. The fuse is
located within the mains switch on the rear side of the stereoamplifier 711.
Model 220 - 240 V, 50-60Hz 10A/T 250V micro fuse 5x20mm
Model 220 V, 60Hz 10A/T 250V micro fuse 5x20mm
Model 100 - 120 V, 50-60Hz 15A/T 250V micro fuse 5x20mm
