Soulution 701 mono amplifier
More power, more control and even lower distortion.
Supported by the new “switched mode” power supply technology the soulution 701 monoamplifier sets new standards in for uncompromising music reproduction and outclasses its predecessor the soulution 700 by far. Colossal power and breath taking performance. Never has an amplifier been so close to perfection, but at the same time the technology must be subordinate – and transparent – to the music. Letting you experience music in all its natural diversity and beauty.
Key features:
- Audio grade “switched mode” power supply (4 × 600 VA )
- More than 1,000,000 µFarad storage capacity in the power supply unit
- Peak current rating of more than 120 Ampere
- Impulse power rating > 12,000 Watt
Highlights
Philosophy
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 (2 MHz/– 3 dB) 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 1,200 W of continuous power (into 4 Ω) and more than 12,000 W 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 µFarad) 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-options
The monoamplifier 701 does have balanced and unbalanced inputs. With the balanced connection the input signal can be bypassed to another amplifier. Switches at the back of the amplifier allow to define the start options for the brightness of the display, the start-condition of the amplifier and the operation mode (mono or bi-amping).
