Two amplifier channels can be used either in "Mono-Mode" or in "Dual-Mode". They work perfectly load stable and 100% level and phase accurate like in the soulution 711 with shortest signal paths and no excessive open loop gain as often associated with solid state amplification. The soulution 701 monoamplifier is an ultra-fast and ultra wideband design (2MHz/-3dB) and provides peak current ratings that would never be possible with a tube design. The unique concept of the soulution 701 monoamplifier combines seemingly contradicting qualities. Precision, Velocity, Stability and Power. The soulution 701 is closest of all to this ideal. As monoblock design it is capable of up to 1'200W of continuous power (into 4Ω) and more than 12000W of transient power. More than enough to breathe new sonic life into even the most demanding, low-efficiency loudspeakers.
Layout
To deliver these impressive power levels we have used bridged amplifiers. Optimized mechanical construction ensures both amplifier circuits are perfectly balanced, sharing identical thermal conditions and ideal grounding. When no music is playing an intelligent control system automatically lowers the quiescent current. And when loudspeakers dictate bi-amping, the soulution 701 monoamplifier can be easily switched to this mode. We think of it as tailor-made amplification.
Power supply
The new power supply of the soulution 701 monoamplifier is based on audio grade "switched mode" modules. Four units with 600VA each combined with highend storage capacitors (>1'000'000 microFarad) provide enough power reserves that allow the 701s reproduce even very complex music signals with ease. Circuitry that does not process audio signals should not be able to influence them. That’s why we use dedicated power supplies within each monoamplifier for the ancillary stages.
Operation
Power, mode and input functions are operated from front panel buttons. Power toggles between on and off states. Mode transfers control of turn-on to an associated preamplifier via soulution’s LINK system. Input selects the desired input and mutes the others.
Connectors and start-up options
The soulution 701 monoamplifier features both unbalanced and balanced inputs. A balanced output can slave the music signal through to other amplifiers. Rear panel switches allow setting of display brightness, start-up options and bridged or bi-amping modes. The LINK system connectors are also located at the rear.
