summarize
Professional enthusiasts know that the role of the power amplifier is to amplify the former signal through a series of repeated, generating voltage and current to push the horn unit forward and forward, so that the speaker to push the air to produce sound.
Think of it in physical terms. The work of sound systems involves electricity, electronic materials science, structural materials science, physics, chemistry, aerodynamics, and most importantly, the aesthetics of sound. The final evaluation criteria for all work is demonstrated by professional sound aesthetics.
As the amplifier circuit level between the signal source and the sound source, the work is to faithfully amplify the previous signal and complete the AC signal that drives the work of the unit.
Many people ask, at what point is a passing grade? With the professional experience of TTR in recent decades, we can simply put forward a few points: what can be achieved is a pass, and what is beyond these points is good.
One, the built-in speaker fully protects the line
The E series post-level power amplifier adopts the new ACL automatic limiting circuit and OLP overload protection technology in view of the bad environment of the professional use place and the diversity of the field conditions.
The ACL circuit will intelligently determine the amplitude, frequency and size of the input signal, and select the most appropriate time to start reducing the amplification factor to reduce the output power. If the input signal continues to increase, the output power will be further reduced. When the input signal returns to normal, the ACL circuit will continue to limit the output power for a certain period of time before amplifying. Ensure the dynamic and power limits of music; The traditional limiting circuit, basically the signal is too large pressure, so it is easy to press the continuous signal into a square wave, and burn the horn unit;
OLP overload protection technology, compared with the traditional protection technology, the biggest difference of the E series post-power amplifier is that the overload protection is added to the negative feedback loop for the first time, in addition to the current limit is more accurate, the distortion after overload protection for the first time reached less than 3%, while the traditional power amplifier is basically more than 10%, and the protection of the hearing sense and the horn has reached a new height;
Two, built-in power amplifier comprehensive protection of the line
E series post-level power amplifier, all components to achieve 98% of the batch machine operation, basically eliminate human factors caused by bad products;
In view of the working characteristics of large current and large heat output, the high power device is directly attached to the radiator design, and the temperature control and power limit are intelligently balanced, and the output power of the amplifier is always limited to the ideal working temperature to ensure the stability of the product itself.
Three, can produce the correct driving unit design
The E series post-power amplifier, in terms of speaker promotion, has done as much as possible to truly restore the sound source signal, especially the core components of the post-power amplifier, power supply, TTR repeatedly tested the impact of A variety of silicon steel sheets on the sound, and finally chose the A-material silicon steel sheet imported from the United States, and with a reasonable proportion of winding turns. To realize the real big dynamic sound performance to the user;
Four, can push the horn sound design.
E series post-level power amplifier, according to the characteristics of singing grade products, we hereby design high-quality dynamic response front circuit, the performance of the human voice to achieve thick and warm, more dynamic and not easy to produce cracking sound effect;
The E series post-amplifier has done a lot of optimization design on these points.
