Nx75W integrated power amplifier components

The SRPP front-stage main voltage amplifier is composed of 6N11J tubes; the use of tubes can soften the sound
. Next is a set of simple RC attenuation tone networks.
    As a high-quality sound reproducing system, this article recommends not using
IC analog inductive graphic equalizers or feedback tone systems with large distortion and poor sound image positioning, because high-quality amplifiers have a wide bandwidth and
do not need to be artificially placed. Certain frequency bands are greatly boosted or attenuated. The RC attenuated tone circuit has a simple structure and
extremely low distortion and noise. It is the circuit of choice for high-quality amplifiers.
    This component is composed of C109, R108, RP103, etc. to form an equal loudness control circuit, which makes
the music components feel full and transparent when listening to small and medium volumes.
    The output part is composed of the module lclol. The internal part of this module is a high-quality symmetrical power amplifier circuit,
including Overheating, overcurrent, overvoltage and other protection circuits ÷ frequency response from 3Hz to 500kHz, distortion <0.5%, maximum sine wave output greater than
120W, is a highly reliable, high-performance, peripheral-free and highly adaptable power module. For the actual five channels including R, 1, center channel,
surround channel SR.SI., I think the optimal power of the main channel is 100W per channel (actual), and the center channel channel and two
surround channels should be no less than 50w (each channel), in order to truly create a cinematic home-like listening effect. 6
    In this way, this combined power amplifier component can use 5 pieces, 2 pieces of output power, each with low output power. The working voltage is ±46V,
the output power of the three blocks is 50w each, and the working voltage of the output part is ±35V. Figure 10-31 is a general power amplifier circuit, the optimal capacity is
550VA, the amplifier components and the power amplifier are all three-dimensionally installed, and the machine The shell size is 430mm×3 50mrn×150mm, and can be installed with
5- channel integrated power amplifier components .
