  If there's no sound from your selected music source on the Pyle Amplifier, first, ensure the Input Selector is correctly set to the current playing source. Then, check that the Music Master Volume isn't set to the minimum; increase it to an appropriate level. Also, verify the Effect Loop bars are correctly inserted horizontally (L-OUT to L-IN and R-OUT to R-IN) and that any connected device is working correctly. Finally, inspect the speaker and speaker cable connections, tightening or replacing them if necessary. If the issue persists, the source player may be malfunctioning, consider replacing it and resetting the unit's power supply.

  Elizabeth HarperAug 19, 2025
  If you're experiencing high-pitched squealing when using the microphone with your Pyle Amplifier, it might be because the microphone is too close to the speakers; move it away. Alternatively, the treble levels on the microphone channel might be too high; try turning them down.

  If there are no graphics on the screen when using your Pyle Amplifier, first, ensure the video cables are firmly connected to the correct video jacks. If that doesn't work, confirm that you're using a CDG disc for playback. Lastly, check that your TV or monitor is set to the correct video setting to accept the video signal.

The Pyle PMXAKB2000 is a 2000 Watt Wireless BT Streaming Stereo Mixer Karaoke Amplifier designed for audio mixing, karaoke, and public address (PA) applications. It combines a stereo amplifier with a mixer, allowing users to blend microphone audio with various music sources, including wireless Bluetooth streaming, RCA inputs, and USB/SD card readers. The unit is rack-mountable, making it suitable for both home theater setups and external speaker systems.

Function Description:

The PMXAKB2000 serves as a central hub for audio entertainment, particularly for karaoke. It features multiple microphone inputs (both 1/4" on the front and rear panels) that can be routed through an effects loop for external processors. The amplifier supports two channels (A/B) for audio and video input, allowing users to switch between different source players like CD/DVD players. A key feature is the Digital Key Control, which enables adjustment of the source music's key to match the singer's vocal range. The microphone talk-over function automatically lowers the music volume when a microphone is in use, ensuring clear vocal projection.

The unit's wireless Bluetooth streaming capability allows for easy connection to mobile devices, enabling playback of music from smartphones, tablets, and other Bluetooth-enabled sources. It also includes USB flash and SD memory card readers for playing digital audio files like MP3 and WMA.

For output, the amplifier connects to external speakers via binding posts (MDP) and offers RCA audio outputs for recording or connecting to other audio devices. Video input/output connectors allow for integration with video displays, TVs, or monitors, ensuring a complete karaoke experience.
