Versatile power amplifier equipped with a new generation circuit
New generation amplifier equipped with MK4 circuit
The thickness, amount of information, and reality of the sound have increased. A versatile amplifier that rivals the high-end class.
The SCA-7511MK4 is a power amplifier with a completely new board design and significantly upgraded sound quality and functionality. It provides a clear and natural sound with a deep and quiet background, and is powerful enough to be used in a normal room.
Significant upgrade in MK4
- Increased amount of information: While retaining the MK3's ability to reproduce an overwhelming amount of information, it is equipped with a newly developed input/output impedance adjustment circuit. This further increases the amount of information, and reproduces the overwhelming amount of information of high-bit, high-sampling with a realistic sound that rivals high-end class.
- Fast start-up: It also takes 30 seconds to start up when you turn on the power, which is much faster.
- Improved sound: The thickness of the sound, the amount of information, and the reality are increasing.
Compatible with current input (SATRI-LINK)
The MK3 had two voltage input systems, but the MK4 has one voltage input and one current input system.
- High-FidelityTransmission: By using SATRI-LINK, furtherHigh-FidelityIt is now possible to obtain.
Stereo/monaural BTL switching function
The SCA-7511MK4 is equipped with a BTL mode, allowing you to easily switch from a stereo amplifier to a monaural amplifier with a switch on the rear panel.
- High output mono: By using two SCA-7511MK4 units, you can enjoy authentic monaural sound with much higher output and no distortion.
- Stereo output: 15W+15W ($8\Omega / 10%$distortion)
- Mono output: 20W
Authentic headphone amplifier performance
This unit is a versatile amplifier that also has the performance of a full-fledged headphone amplifier.
- connection: Please connect directly to a CD player and enjoy the sound of real CDs that you have never heard before.

Overwhelming clarity and silence – the pure sound produced by the SATRI circuit
The MK4 has undergone a major overhaul of the board design and has kept noise levels surprisingly low. When the playback starts, the "silence of the background" is completely different, and there is a feeling that the sound rises quickly from there. Subtle nuances emerge without being buried, making the contours of the sound feel sharper and more natural.
While maintaining the clear, uncolored tone typical of the SATRI circuit, the transparency and amount of information are further extended, and the atmosphere and spatial nuances engraved on the high-resolution sound source are brought out firmly.
Natural texture and three-dimensional sound field expression
The effect of the new impedance adjustment circuit increases the depth and realism of the sound, and the depiction of details is smoother. It has a natural tone with no sharp points, so there is no stress on your ears even during long listening sessions.
The sound field shows a way that completely exceeds the size, and the depth and three-dimensionality are much richer. The positional relationship of the instruments is very clear, and there is a reality that makes the recording space stand up as it is.
Driving power that doesn't seem to be small - BTL for even more room sound
Contrary to the impression you get from the rated 15W number, the actual driving force is more powerful than you might imagine, and even medium and large models can be easily played with highly efficient speakers. The midrange is dense, and the low frequencies are tight and tight, giving the overall center of gravity a sense of stability.
Switching to BTL mode further enhances the punch and sense of scale of the sound, allowing it to perform as a full-fledged mono power amplifier. When used in a two-unit configuration, the spaciousness and stability make you forget that it is a compact chassis.
A versatile model with a high degree of completion as a headphone amplifier
The front headphone jack (200mW) delivers a quality that feels far from a mere supplementary feature, offering very high transparency and resolution, giving a sound quality close to that of a dedicated unit. It has enough capability to serve as the main unit even for desktop use.
It also supports current transmission via SATRI-LINK, and when combined with DACs or preamps from the same series, the freshness of the sound is significantly enhanced, giving the impression that the overall level of your system is elevated.
