VU meter circuit
The circuit is placed parallel with the exit of power amplifier and gives the level of signal from output. Changing resistance R1 in the input circuit, we adapt the indication of power in the resistance of loudspeaker that we use.

Wide band high frequency amplifier circuit
This is a wideband high-frequency amplifier circuit designed for a frequency range between 75-150 MHz. It utilizes a PNP transistor amplifier to enhance signal strength before it reaches the receiver of devices such as phones, FM radios, or amateur radios....
simple-amplifier-with-c945mje340-and.html
This simple amplifier delivers good sound quality with a power output of approximately 10 to 14 Watts and operates on a supply voltage of about 34 to 36 Volts DC. It requires a preamplifier due to its limited advanced features....
Stereo balance meter
To utilize the indicator, set the amplifier to mono mode and modify the balance control until both LEDs are equally lit. The amplifier is now in optimal stereo mode balance.
The circuit described involves an amplifier with a built-in indicator system...
Stereo Audio Isolator
This circuit is useful for removing ground loop hum on a remote line level audio signal line. It can be used to connect a computer sound card to a stereo amplifier's line input. Other uses include tapping into a line...
Stereo Balance Meter Circuit
When the L and R signals are equal, no output is present from U1, and pin 6 is at a steady 4.5 V. Unbalanced audio causes the LEDs to vary in brightness, which indicates a difference that corresponds to the...
VU LED Indicator Schematic
The VU LED indicator is simpler and smaller than its analog counterparts and is commonly used in audio equipment. This version is based on a National Semiconductor integrated circuit (IC) that utilizes a logarithmic response. Each LED operates with a...
Stabilized-amplifier
This amplifier operates across a broad range of gains, typically from 1 to 10. It integrates the LT1010 with a fast discrete stage and an LT1008-based destabilizing loop. Transistors Q1 and Q2 create a differential stage that converts to a...
Active-limiting-amplifier
The modified inverting amplifier employs an active clamp to precisely limit the output swing. Consideration must be given to the VBE of the transistors. The output swing is restricted by the base-emitter breakdown of the transistors. A straightforward circuit configuration...
