Three-channel tone control
The input signal is fed through SKI to the first active stage, which is constructed around IC1. This stage is configured as a non-inverting amplifier, with its gain determined by the ratio of R3 and R1. In this configuration, the...
Tone Control Schematic
Based on the classic Baxendall tone control circuit, this provides a maximum cut and boost of around 10dB at 10KHz and 50Hz. As the controls are passive, the first transistor, Q1, is configured as common-collector to act as a buffer...
Audio Equalizer Circuit
Designed for communications use, this equalizer circuit utilizes a Mitsubishi M5226P audio equalizer IC to modify frequency response. It operates with a supply voltage ranging from 9 to 20 V. Capacitors C6 through C16 are polyester film capacitors with a...
ld168 audio control circuit diagram of a voltage-controlled flash decoration
The circuit depicted in the figure involves the LD168, which functions as a sound level indicator for tape recorder speakers. It features four outputs capable of directly driving multiple light-emitting diodes. Additionally, the device can be activated by a thyristor...
Ten-segment frequency equalizer
Figure 1-97 illustrates a ten-band equalizer circuit with its initial connection. Figure 1C represents the utility voltage amplifier, with R7 functioning similarly to the island depicted in Figure 1-92 R1. Additionally, R2 and the transistors VTr to VTio form the...
Bass-treble tone control circuit
The LM1036 is a DC-controlled circuit designed for adjusting tone (bass and treble), volume, and balance in stereo applications such as car radios, televisions, and audio systems. It features an additional control input for straightforward loudness compensation. The circuit includes...
Simple Easy Parametric and Graphic EQs Plus Peaks and Notches
The sound of a wah pedal is characterized by a resonant peak in the signal that can be adjusted. In contrast, a notch represents a sudden decrease in level at a specific frequency, which can be advantageous for achieving particular...
TONE CONTROL AND SUBWOOFER OUT
PT2350 is a tone control subwoofer crossover low pass filter chip utilizing CMOS technology. It features a tone control range of +10dB (50Hz, 4 kHz) and a subwoofer low pass filter of the second-order Sallen Key design. The roll-off point...
3 band equalizer circuit
This 3-band equalizer circuit is an active filter network designed to adjust bass, midrange, and treble audio frequencies. It utilizes the LM833 operational amplifier from National Semiconductors, which is known for its very low noise figure and wide frequency response.
The...
