When SW1, SW2 or SW3 are open the input sensitivity is suited to high-output devices like CD players, tuners, tape recorders, iPods, miniDisc players, computer audio outputs etc. Sometimes, the 750 Ohm value for R3, R13 and R17 resistors could be not easy to.... -
As numerous or as few channels as are needed may be added to the mixer. Do this by just duplicating the input "sections" that are shown on the schematic design. An audio amplifier is an electronic amplifier that amplifies low-power audio signals (signals.... -
Welcome to the weblog where we discuss about electronic circuits schematics, PCB design, diy kits and electronic projects diagrams. This mixer shows you how to accomplish microphone pre-amps for low and hi impedance mics. Use the everyman babble op-amp you.... -
The four main input channels are identical, have independently adjustable input sensitivity, tone, panning sound. The fifth entry - linear channel. Despite the cheap and primitive, the work Mini Audio Mixer "Impulse MM-04" was quite satisfactory .. -
Micropower and low-voltage op amps allow you to build high-performance analog-signal processors that require no batteries or wall transformers. Instead, you can use a capacitor as a power source. The circuit in Figure 1 shows an analog mixer designed for.... -
