It's a monitor amplifier
You can, but it will not sound loudly. A microphone always needs a pre amplifier.
To connect an equalizer to the Fisher CA-871 stereo amplifier, first, locate the tape monitor loop or the auxiliary inputs on the back of the amplifier. Connect the output of the equalizer to the tape monitor or auxiliary inputs using RCA cables, and then connect the output of the amplifier to the equalizer's input. Make sure to set the tape monitor switch to the "on" position to route the audio through the equalizer. Adjust the equalizer settings as desired for optimal sound.
To hook up a monitor to a Peavey XR 680E amplifier, first, ensure the amp is powered off. Use a balanced XLR or 1/4-inch TRS cable to connect the monitor output from the amp to the input of your monitor speaker. If you want to use a stage monitor, connect the cable to the appropriate monitor output, usually labeled as "Monitor Out" or "Aux Out." Finally, power on the amp and adjust the monitor level as needed.

current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.
A voltage amplifier does not have to supply significant current bur a power amplifier does.
In audio look at an amplifier. It will be always a voltage amplifier.
