Precision, stability and velocity…
… just a razor-thin fraction behind our reference designs of Series 7, this was the design goal we have set for the 511 stereo amplifier. The 511 is equipped with the same “switched-mode” power supply technology, optimised for audiophile applications, as our series7 products. Additionally it is optimised for shortest “signal paths” for the music signal but as well for shortest paths and optimal flow of the current supplying the amplifier stages. Get inspired by the uncompromising music playback and enjoy the diversity and natural beauty of the music. A sound experience, of which everyone will be enchanted. Convince yourself.

Amplification
The amplification circuit similar to the technology used for the 711 and 701 amplifiers. At its core is a proprietary voltage amplification stage that consists of linearized amplifiers operating up to a cut-off frequency of 80 MHz. Current amplification is done in three stages, each using a very small and thus almost linear operating range. The high Class A operation supplemented by 500,000 µF of storage capacitance in the power supply results in a nearly infinite impulse response. Massive copper bars on the amplifier board and to the speaker terminals ensure that all the power of the 511 stereo amplifier is available to drive the speaker. This ensures the 511 does not get the plaything of the loudspeakers, but controls them with the appropriate precision, power and velocity asked for by the music signal. High-precision idle current management ensures optimal Class A operation for all conditions, without requiring any readjustment in the music signal. Optimal sound is thereby guaranteed immediately from switch on.

Power supply
A total of 10 power supplies – optimised for each function – feed the 511 stereo amplifier. Circuitry that does not process audio signals should not be able to influence them. Therefore those supplying the digital and audio circuits are electrically isolated from each other by optocouplers. Four cutting-edge switched-mode power supplies combined with more than 500’000 µFarad of storage capacitance deliver 2,400W of audiophile quality power. They feature high performance filtering at the input and output, and six linear, high speed, ultra low noise voltage regulators to deliver considerably more stable power than any conventional, transformer-based technology.

Safety
Control circuits that protect the 511 stereo amplifier against RF or DC signals at the input, and short circuits at the output ensure safe operation in all situations. The input level is also monitored continuously. In case a malfunction is detected the 511 stereo-amplifier is muted and will automatically power down.

Operation
The 511 stereo amplifier is operated via push buttons and a rotary control on the front panel. It can be switched on remotely with other soulution devices via the LINK system.

Operating modes
The 511 stereo-amplifier can be used in three different setups:

Stereo-mode: 140 W @ 8 Ω, 280W @ 4 Ω, 560W @ 2 Ω per channel
Dual-mode: 140 W @ 8 Ω, 280W @ 4 Ω, 560W @ 2 Ω per channel
Mono-mode: 560 W @ 8 Ω, 1’120 W @ 4 Ω, 2’000 W @ 2 Ω
The operating mode can be changed in the menu functions of the 511 stereo amplifier.
