Overview
Pyle built this as a multi-channel amplifier and Bluetooth receiver for paging and background music, pairing wireless audio with two microphone inputs and rotary controls for bass, treble and echo, aimed at small venues and home setups rather than home theater surround sound.
Background music and paging cover the daily use case, with the talk-over button cutting music the moment mic one speaks. The control layout stays entirely manual dials and buttons, so anyone wanting an app or a channel display should look elsewhere.
Who it's for
A front desk, workshop or small venue running background audio and occasional announcements suits this amplifier well. Anyone chasing multi-room streaming, an app, or cinema-style surround should look at a full AV receiver instead.
Pros and cons
- High peak power rating for a compact amplifier
- Talk-over button gives mic priority during announcements
- Seven inputs cover USB, SD card, FM, and aux
- Echo control included for karaoke microphone use
- No digital display for source or channel status
- No app or smartphone control, manual dials only
- Warranty listed as just one year
- Signal-to-noise ratio and frequency response not listed
Performance notes
Output runs through a multi-channel design so several speaker pairs can be driven off the same unit, with bass, treble, and echo handled by dedicated rotary controls rather than a menu system. The talk-over circuit works by sensing the mic one input and dropping music volume automatically whenever someone speaks into it, restoring level once they stop.
