Dynamic noise reduction with DC volume control
A dynamic noise reduction circuit and a DC volume and tone balance control circuit, which are applied to the input stage and the discharge line between the amplifier.
The described circuit configuration incorporates two primary functions: dynamic noise reduction and volume/tone...
Analog Audio Delay Line: Expand Your Virtual 3D Sound Space
Creating a variable space in a small room can be enjoyable; however, designing an actuator to move a wall or room partition poses challenges. This can be achieved using an analog audio line delay.
To implement a system that allows for...
ARRL Handbook Audio Intelligibility Enhancer
Assistance is sought for building the N4GG audio intelligibility enhancer project as detailed in the ARRL Handbook. A circuit board has been ordered from Far Circuits, but there are difficulties in sourcing the necessary components. Attempts have been made to...
Signal Conditioning Analog Front-end for Microcontrollers
The I/O board incorporates 16-bit resolution voltage analog inputs and outputs, along with a 4-20mA current loop transmitter and receiver for microcontroller applications. The document discusses amplifier circuits and schematics, including a signal conditioning variable gain amplifier, analog filter, and...
Discrete components sound and light control stairs delay switch circuit 4
This circuit describes a sound and light control delay system for a walkway stairs light switch. It involves various components including 220V AC electric bulbs, diodes (VD1-VD4), and resistors. The circuit utilizes a rectifier regulator to stabilize the voltage supply....
Compressor Protector
This circuit monitors the AC voltage of the power line. Upon a power failure, when power is restored, the circuit introduces a five-minute delay before energizing relay K1, which safeguards the compressor against low voltage conditions. U1 is a 16-stage...
Balanced microphone preamp project
Well, it's pretty much a PAiA preamp - usual input circuitry followed by one half of dual op-amp rigged in fixed 20dB amplification circuitry, followed by second stage which is adjustable for up to 40dB amplification, for up to 60dB...
LM1894 Principles and Applications a
A typical representative of dynamic noise reduction developed by the United States National Semiconductor is the LM1894. Its principle is illustrated in Figure 1-1070, where the left and right input signals are processed through a main signal path. The input...
Hi-ficompressor-with-pre-emphasis
The compressor includes a high-frequency pre-emphasis circuit (C2, R5, CS, R14) that addresses this issue. A corresponding de-emphasis circuit on the expander is necessary. More sophisticated designs may allow for variable pre-emphasis.
The compressor's high-frequency pre-emphasis circuit is crucial for enhancing...
