The R60 inherits the success of the R20 mono power amplifier and the R30 integrated amplifier. In order to ensure that the output characteristics perfectly match the electrical and acoustic characteristics of the electric speaker, it is designed and manufactured under the concept of uncompromising. With its high performance and high sound quality Combined, it has become the reference power amplifier in the Deson product line.
 
● Design of switchless distortion amplifier
 
Thanks to Dussun's adaptive biasing technology, the R60's power amplifier always maintains a Class A output even if the speaker impedance drops significantly and the output power doubles. This allows the R60 to avoid the regret of traditional pure class A amplifiers returning to class B when the speaker load impedance drops, bringing it closer to an ideal class A amplifier..
 
● Power
 
Three power supplies provide stable and clean direct current for different circuits. High frequency noise is pre-filtered on the AC power bus with receptacles that contain common-mode and differential-mode filters. Individual fuses on the AC power bus are used for complete protection..
 
All control circuits are powered by a separate low-voltage DC power supply, which prevents noise from the control and display circuits from entering the audio circuit.
 
As an amplifier to look forward to, the audio circuits for the left and right channels are powered by two independent power supplies, and large custom-designed toroidal transformers (800 watts/each) are used to reduce the AC power to the appropriate voltage required by the audio circuits , followed by the separate rectifier filter, is an active regulator used to power the voltage gain stage line.
 
The separate power supply for the left and right channels ensures that the power supply of one channel does not modulate the power supply of the adjacent channel. This dual mono method is most conducive to the reproduction of dynamics and stereo image details..
 
● Power amplifier
 
The R60 output stage uses high-performance output devices (12 per channel). All output devices have been carefully selected by Dussun technicians, which allows us to build each channel with closely matched transistors in gain to ensure that no one device will take on more work or run in extreme heat than any other. The result is better sound and better amplifier durability.
 
In the design, we have considered and provided the most appropriate heat dissipation conditions for this high output capacity amplifier. The output transistors are distributed as much as possible around the circuit board of the current gain stage to facilitate heat dissipation, and are arranged on both sides of the chassis. The radiator provides good air convection.
 
●Perfect protection
 
Protection against internal or external device failure is one of the integral features of the Dussun design philosophy. The R60 uses a range of forms of protection, both for itself and for the speakers and other devices connected to it.
 
Surge Snubbers - Provides protection against occasional or delayed surges.
 
Overload protection circuit - used to avoid high energy and high frequency ringing when the amplifier is overloaded, which may cause damage to the speaker. When the amplifier is overloaded for more than a predetermined time and the speaker wire or output is shorted, the overload protection circuit will shut down the amplifier.
 
DC Servo - Used to correct for potentially harmful DC drift. The correction range is ±1 V. If the problem exceeds the range of the servo, the amplifier will be shut down.
