Onkyo M-5060R Integra Super Servo Stereo Power Amplifier

Product description
This super servo integral type stereo power amplifier analyzes the amplifier not only as a single electric circuit, but also includes the acoustic aspects of the reproduced sound field, and thoroughly investigates the problem of time difference distortion.

In addition to Onkyo's proprietary W Super Servo method, it also uses a Super Servo Integral method that suppresses the effects of the speaker's electromotive force.
When the voice coil of a speaker vibrates, a microphone effect occurs in which an electromotive force is generated within the coil, which affects the reproduced sound. The super servo integral system employs a circuit that reduces the influence of this electromotive force to -20dB or less, and applies positive and negative feedback using a linearity correction circuit only to the current amplification stage to improve the linearity of this stage. This has dramatically improved and suppressed time difference distortion.

The final transistor operates using a linear switching method.
This method uses two transistors for amplification, similar to class B operation, and uses a special bias circuit to correct the linearity of the joints of the operating curves, which is a problem in this case, to obtain linear operating characteristics. Masu. As a result, crossover distortion is reduced, and characteristics close to class A operation are obtained while retaining the benefits of class B.
Furthermore, by using a High fT power transistor, switching distortion is suppressed to a negligible range.

Logarithmic compression and peak hold are performed using a highly stable monolithic IC, and it is equipped with a large peak meter that suppresses left and right variations.
In order to obtain high-speed response, it is driven by a dedicated meter drive circuit using an operational amplifier, and the level can be changed from 0dB to 130W and 13W with the front switch.

A monolithic IC is used for the protection circuit, which not only improves stability, but also detects DC leakage voltage appearing at the speaker terminals and overcurrent in the power stage, and in the unlikely event of an emergency, the relay will be shut off to protect the circuit components. .
A highly reliable gold-plated silver contact relay is used for the speaker switching relay, and the use of a parallel connection prevents deterioration of the damping factor.
In addition, the low-pass filters for DC voltage detection are independent on the left and right, and work even when the left and right polarities are different.

The power supply section uses a large twin-wide type power transformer, and the rectifying chemical controller is a low-inductance circuit that is a multi-tab type low impedance wide range chemical controller that is directly connected to the bus earth after careful consideration. I am using it as.
In addition, the power supply and distribution to each section, the ground line, etc. are also thoroughly low impedance.

It uses an auto-tracking bias method that detects local temperature changes in each part and provides a stable bias supply.
