The Pyle PDA7BU is a 5-channel home theater amplifier built for rooms that need real coverage — front, center, and surround channels plus a dedicated subwoofer output, all run from one compact receiver. Bluetooth wireless streaming connects phones, tablets, and computers using a dedicated antenna for a stronger signal. Two microphone inputs with adjustable echo and mic volume make this a genuine karaoke-capable amplifier. USB and SD card inputs handle digital playback, and FM radio with antenna rounds out the source options — all shown on the front LCD display, which reports track info, EQ settings, and Bluetooth connection status. Bass, treble, balance, and independent subwoofer volume controls are adjustable from the front panel, and a source selector switches between AUX, CD/DVD, and TV RCA inputs. Rack mount hardware is included for permanent installation, along with a wireless remote and FM antenna. Built to power a full room, not just a pair of speakers, the PDA7BU is ready for movie nights, karaoke parties, or everyday listening.
