In terms of configuration, if the requirements are not high, your equipment can cope with it by adding a mixer. There are also players such as dvd and cd. It's best to add a reverberation effector to polish the sound better.

The mixer, also known as the mixer, amplifies, mixes, distributes, modifies and processes multiple input signals, and then outputs them through the mixer. The mixer is an important equipment for playing and recording programs in modern radio broadcasting, stage amplification and audio program production systems.
Mixers can be divided into analog mixers and digital mixers according to the signal output mode.
The mixer has four main functions:
The first function is to amplify the program signal. When signals from different program sources enter the mixer, different signals need different amplification, so the mixer must be able to process different signals separately. For example, the musical signals and vocal signals of various musical instruments are different in amplitude and need to be processed separately.
The second function is to adjust the frequency of various signals (i.e. tuning). We know that different signals have different timbres due to their frequency spectrum distribution, harmonic components and other reasons, and the influence of buildings on sound has greatly changed timbres. The sound engineer should process different sound signals entering the mixer according to different amplification environments, so as to make the sound as close as possible to the original sound. Each channel of the mixer has the same processing means, such as three-stage equalization, gain controller, high-pass filter and so on.
The third function is the combination of signals. After the mixer adjusts various signals, it combines them into standard left and right channels (stereo) and outputs them as the input signals of the next level equipment, which is the most basic function.
The fourth function is the distribution function. In addition to the main output of stereo, the mixer can also provide more than two auxiliary output signals, which has two purposes: one is to monitor the sound room or listen back to the stage; The second is the excitation signal used as the effector.
