The AKJ7041 digital key & echo karaoke mixer contains three microphone inputs and four music source  inputs.  Up to three microphone inputs can be mixed with one of the four music sources. There is a music volume control knob to control the music volume. There are two microphone volume control knobs, where one control knob is used to adjust the volume of the Mic 1 input and the other is used to adjust the volume of the Mic 2 and Mic 3 inputs.   The tone of the microphone input sound can be adjusted through a MIC TREBLE control knob and a MIC BASS  control knob respectively.

The AKJ7041 digital key & echo karaoke mixer  further contains the echo control function, the key control function, and voice canceling function.  The echo control function enables the users to control or adjust the echo volume, the echo delay, and/or the echo repeat.  The key control function allows the users to adjust the key up to +4 or -4 steps.  The voice canceling feature is controlled by the Vocal Cancel Button and the Vocal Partner button.  The vocal cancel feature can be used to remove the multiplexed vocal portion of a song while the vocal partner feature allows the multiplexed vocal portion of the song to be removed only when the microphone inputs are present.
