A hi-fi amp around 01

Description: After extensive practice by enthusiasts, a recommendation has emerged for a hi-fi amplifier setup that includes a preamp, as illustrated in Figure 5-117. This amplifier features dynamic noise reduction and a DC pitch volume controller. The I.M18 9 4 is a non-complementary noise reduction integrated circuit (IC) that effectively reduces noise levels by approximately 10 dB across various media, including ordinary tape, VCD discs, and FM radio. This circuit is characterized by low distortion and simplicity, allowing users to enjoy diverse musical environments. The high bass response caters to different preferences, making tone control an essential component in sound systems.

For hi-fi applications, tone control requirements include the ability to alter frequency response without compromising sound quality. The recommended IC for monolithic DC tone volume control is the I.M1036, which offers treble, bass, volume, loudness, and balance adjustment functions for user convenience. The circuit is designed to maintain loudness and balance in a normally open state, eliminating the need for frequent adjustments. By utilizing DC voltage control at the end of the control path, the potential does not interfere with the signal path, allowing for the use of unshielded cables and minimizing sliding noise associated with traditional potentiometers. A single potentiometer can manage dual sound channel adjustments, reducing the need for expensive high-fidelity potentiometers.

This system is tailored for audiophiles seeking a high-quality tone volume control solution. It features strong bass and clear tonal quality, addressing common issues such as weak sound control. The system is capable of producing a rich sound profile, with adjustments allowing for enhanced low-frequency control, particularly when paired with additional subwoofer plates. During the debugging of the dynamic noise reduction device, it is recommended to use a blank tape for playback, maximizing treble while minimizing bass attenuation. Volume adjustments should be made carefully to avoid excessive noise levels in the speakers, and this process may need to be repeated for optimal performance.After many enthusiasts practice, following a recommendation before and after class hi-fi amplifier. The amplifier preamp shown in Figure 5-117. By the dynamic noise reduction a nd DC pitch, volume controller was opening I.M18 9 4 is a non-complementary noise reduction IC, capable of ordinary tape, VCD discs, FM radio as 1 0 db down noise, it is widely used. And low distortion, a simple circuit. For everyone to enjoy different musical environments, high bass have different hobbies, so the sound is a combination of the tone control must essential part.

HiFi for tone control requirements are: change the frequency response, in line with a particular interest, but the sound quality lossless. It is recommended monolithic DC tone volume control integrated circuit IC I.M1036 this port has treble, bass, sound volume, loudness, balance adjustment function 6 for ease of use t The circuit has been designed in the loudness and balance normally open like state, you do not have to adjust.

Since the end of the control DC voltage control are used, the potential is not in the signal path, thus potentiometer connected to peripheral circuits without the use of shielded cable, but also eliminates the sliding noise potentiometer, potentiometer single joint can be achieved double sound channel adjustment, without the use of costly high fidelity adjustment potentiometer can be achieved, is the production of high quality enthusiasts tone volume control system characteristics surname Chong Dan He established a blind wife Qin Ming Gan mouth. - System Strong bass tone of apartment. bone tone when a boat moving Merced no harsh tone control circuit common problem of weak scared, very nice; the level previously installed some cool sounds hard, high and low due to excellent power amplifier, but also the effect of moves mountains; this excellent low-frequency tone control control over some of the additional subwoofer plate © when debugging dynamic noise reduction device, a plate not available blank tape-recorded program playback, will treble the maximum lift.

Bass minimum attenuation, adjust the volume at full t I.M1894, among foot lkfl adjustable resistance, noise in the speaker is about to increase large state, it is best to work this step repeated several times.
