Based on my research so far it seems relays or FETs are two possibilities.

Audio Selector Circuit. It provides a built-in 2-Channel to6-Channel Translator which can directly mix traditional stereo channel to simulate a 6-Channel audio output. Accepts inputs from and provides power to RAMX2 and RABX2 mixers. The setting is not fixed but is stored in an EEPROM which is read when power is applied.

This circuit designed for audio applications allows the user to select which input signal will be enabled when the system is switched on. The circuit board space can be saved by integrating the noise grounded isolation amplifier and audio selector into one chip. Id appreciate a bit of help figuring out a good way assuming one exists of routing an audio signal to one of 4 possibly more identical output speakers.

The control circuit can be momentary switches to activate and it takes care of the release of the relay when switching over. As shown in the circuit diagram the ten input signals numbered 1-10 are applied to the bases of transistors T1-T10 via capacitors C1-C10 respectively. All you need is a switch a few audio sockets an enclosure of some sort and some wires.

In this Instructable Ive made a switching circuit for 2 inputs and one output but this can easily be expanded to several inputs and one output by swapping out the switch and using more audio sockets. Due to its high performance small shape and multi input response njm2754 is suitable for on-board audio equipment. - Albert Einstien _____ LM380 Bridged Guitar Amp Oatley K301 Phono Pre-amp Oatley K272 Headphone Amp Tube proto-board.

Here is a circuit that helps you choose between two stereo sources by simple touch of your hand. Alternatively an all-off can be implemented with either a fourth button or a smart control circuit that disables the active relay when the same button is pressed twice. Here is the circuit diagram of a simple 3 channel audio splitter based on the IC NE5532.

And three other channels of the remaining S1 short circuit to ground immediately Which there are R1-R16 and C1-C8 serve as directly the short circuit protection devices to the ground of signal input channel that is. Figure 1 the analog signal selector switches circuits. Because IC 4052 contain two pair of 4 channel switch so we can use only one IC in stereo system.

Now you can control the Bass Treble and Volume by rotating three potentiometer on the circuit. The add-on circuit presented here is useful for stereo systems. When switched input is active 1.

The circuit uses just two CMOS ICs and a few other componenets. Im working on an external circuit to add to my arduino synth. Each switch input includes a voltage divider to allow the switch to work in the linear zone of the characteristics this ensures low audio signal distorsions.

This is achieved by connecting the outlet 4 and reset. This circuit has provision for connecting stereo outputs from four different sourceschannels as inputs and only one of them is selectedconnected to the output at any one time. Audio Input Selector Circuit schematic.

Audio Amplifier Circuit Overview In the first part of lab1 you will construct a low-power audio amplifierspeaker driver based on the LM386 IC from National Semiconductor. A Automatic input selector. Audio input Selector Schematic Circuit Diagram.

Custom Engraved Channel and Zone markings will not wear off. From circuit in Figure 1 a selector switchesS1 will be selectness a input signal of 4 inputs put it to work only one input channel. It has a high small signal and power bandwidth making it well suitable for high quality audio applications.

We use the circuit above to select audio input from DVD AUX TUNER and MP3 PLayer. PT2323 is a 6-Channel Audio Selector utilizing CMOS Technology specially designed for Home Theater System. April 18 2021 315pm 1.

3 channel audio splitter. RASX4 4 Channel Remote Audio Selector. This stereo audio switch circuit allows that with only one switch to select one of the four stereo channels.

This Instructable is about making a very simple 35mm stereo audio switching circuit. B Detect audio signal to switch relay on and after some time off again when the music has stopped. Turn the channel and turn the volume control.

This circuit has provision for connecting stereo outputs from four different sourceschannels as inputs and only one of them is selectedconnected to the output at any one time. At the push of a button when an active input 4 is activated again enter 1. System April 17 2013 1106pm 1.

When power supply is turned âonâ channel A AR and AL is. Digital Audio Selector Switch Circuit Diagram. After pressing of the button activates the following input.

The key to a successful build is to keep the smoke IN the circuit. This circuit is so compact that it can be fixed within the audio power amplifier cabinet and can use the same power supply source. In the second part of the lab you will construct a.

The circuit comprises a priority selector circuit which monitors the designated priority audio source for signal amplitude and duration a micro-computer then operates a digital fader to phase in the priority signal and also to phase in the alternate signal in the absence of a sufficient priority signal. To activate selector we must set INH-pin to LOW grounded. The circuits designed to play audio from a L and R channel through a built in speaker by default but upon detecting a headphone.

4 Standard RCA inputs. Headphone detection and output selector circuit. RABX2 and RAMX2 can be programmed to any channel via jumpers.

For this audio signal source selector you dont need to use any mechanical contact or push buttons because you can choose between two stereo sources by simple touch of your hand. To operate the circuit connect the components as per the circuit diagram give 15v and -15v supply to TL072 opamp and give audio input from mobile by connecting 35 mm audio jack to the circuit. NE5532 is a dual internally compensated low noise opamp from Fairchild semiconductors.

Route audio through output selector circuit using Arduino. Easy to operate intuitive interface. -Les We cannot solve our problems with the same thinking we used when we created them.

Then to select one of the input we use the binary code in A-CTL and B-CTL pin. 4 Channel Stereo Audio Selector. This circuit helps you to choose one from two audio signal sources connected the audio amplifier stage.

Single power supply 9V I2C Bus Interface as well as very low Total Harmonic Distortion THD 0005 and other features are. The circuit given here is a novel way of selecting one out of ten audio signals digitally without any of the foregoing drawbacks. The audio amplifier will be a self-contained battery-operated component.
