How to connect the mixer of DSP and the amplifier of the effector?

1. Send the signal from the auxiliary sending socket (AUXSEND) of the mixer to the INPUT socket (input) of the effector for effect processing, and then send the signal from the OUTPUT socket (output) of the effector to the auxiliary returning socket (AUXRET) of the mixer. The signal level is controlled by two knobs and sent to L and R buses.

2. Multiple channels work at the same time.

After the signal is sent from the auxiliary sending socket, it enters the input socket of the effector. After processing, it takes the signal from the output socket and sends it to any line input socket of the mixer. At this point, the signal entering the mixer from the line outlet can be regarded as a new sound source, which is a sound signal reverberated and delayed by the effector. The volume can be controlled by a volume controller.

3. Use the jack of a single microphone to process the reverberation effect sound of the singing microphone separately.

This socket is a big three-core interface. The tip of the big three-core interface is SEND, and the signal of the microphone is taken out from this point and sent to the INPUI socket of the effector. The sound signal processed by the effector is sent from the output socket of the effector to the ring inserted into the socket of the mixer, and then returns (ret). The metal sleeve of the plug is a common ground wire.

4. All audio signals are processed by effects.

The effector is connected to the whole sound system (equivalent to series connection), that is, the sound signal after the effect processing is output from the mixer bus to the effector and does not return to the mixer, but continues to be input into the voltage limiter or the room equalizer.

5. Send the connection.

Connect the input of the effector with the auxiliary output of the mixer, and the output of the effector is connected with any one or two inputs of the mixer. The advantage is that it can send signals to the effector, and the effector can handle a variety of sounds.

Amplifier front stage

Multipole power amplifier is generally divided into two parts, front electrode and rear driving electrode.

Generally speaking, the first stage is a differential amplifier circuit (or a * * * collector amplifier circuit). This is mainly used to select the useful signal (differential mode signal) that needs to be amplified from the signal, followed by a multipole * * * emitter amplifier circuit for amplifying the large and small signals. It should be noted here that most of the signals are enhanced at the front pole, but the current is not greatly enhanced.

The driving electrode of the back electrode is mainly used to enhance the current intensity of the signal. * * sets of amplification circuits are generally used. If speakers and the like are driven behind, power amplifier circuits such as Class A and Class B analog circuits are needed to increase the signal power.
