Review on 🔊 Pyle PT390BTU Wireless Bluetooth Power Amplifier System - 300W 4 Channel Home Theater Audio Stereo Sound Receiver Box with USB, RCA, 3.5mm AUX, LED, Remote - Ideal for Speaker, PA, Studio - BLACK by Franz Esquivel

Love the extra USB port and an SD card reader. Also 2 microphone inputs with echo. I will be using this with my karaoke machine. 300 watts divided into four channels at 75 watts per channel, which is very good. I don't like the radio part of the receiver. There should be a knob that you can turn to set a channel. Overall, this is a very good receiver for the money (around $100). The blue tooth sometimes breaks out. Today's date is July 21, 2021. Ever since I've been using the receiver, I've had a problem with the microphone jacks. My mics are low impedance and I connected a transformer to convert low z to high z (z is the impedance). However, the 1/4" headphone jacks did not fully fit the jacks on the receiver, although other 1/4" phone jacks did. The bushings fit all of my other gear. I think the manufacturer had a bad batch of 1/4" sockets. I bought another transformer and will update this review. I highly recommend this receiver. I just got another transformer and it doesn't fit a female either Microphone I just ordered a Performance Plus Hi Z to Low Z Switchable Line Transformer Microphone Cable Adapter, XLR Female to 1/4" Male (MCT-1S) which should work as there is no ferrule attached to the end of the cable is. Jack. If you have low impedance microphones, be aware that there is an issue with the type of connector used. Pyle should use different microphone jacks on this receiver. A new transformer costs $34.50. If you use a high-impedance microphone, this is not a problem. I still really like the receiver.
