KNA MP-Wi Wireless Mandolin Pickup — Cable-Free Piezo Amplification

The KNA MP-Wi is a portable bridge-mounted piezo pickup with integrated UHF wireless transmission, engineered specifically for mandolin players who want to amplify their instrument on stage without trailing cables. A passive piezo sensor slips between the bridge saddle and base to capture the natural voice of the mandolin, while the included transmitter and receiver pair instantly for a stable, low-latency signal to an amplifier, mixer, or audio interface. The KNA MP-Wi is the right choice for performing mandolinists who need authentic acoustic tone and the freedom to move around the stage.

What Sets the MP-Wi Apart

Unlike conventional magnetic or stick-on pickups, this model uses a passive piezo design that reproduces the mandolin's wooden resonance with high fidelity. The integrated UHF transmitter pairs with the receiver in seconds and offers a transmission range strong enough to pass through interior walls, while remaining immune to typical stage interference. A tonewood housing blends visually with the instrument, and the cork-padded adjustable clamp legs with soft suede cushioning protect the finish during long sets.

Wireless Performance and Power System

The wireless stage experience depends on a stable signal and reliable power. The MP-Wi delivers both through UHF transmission and a rechargeable lithium-ion battery integrated into the transmitter and receiver units.

• Wireless Technology: UHF — strong, low-latency signal with anti-interference performance
• Battery Type: Integrated rechargeable lithium-ion — long-lasting power for extended sets
• Charging Port: USB-C — faster top-up between gigs

Pickup Design and Signal Control

The piezo element and onboard controls determine how faithfully the mandolin translates through the system. KNA pairs a passive bridge sensor with simple physical controls so the player stays in command of the output level at all times.

• Pickup Type: Passive piezo — captures authentic acoustic resonance without batteries in the signal path
• Volume Control: Onboard "+" and "−" buttons — adjust output directly from the instrument
• Wired Backup Output: 1/8" (3.5 mm) jack — plug straight into an amp or audio interface when wireless isn't needed

Installation and Instrument Compatibility

The MP-Wi is designed for quick, non-permanent mounting on standard mandolins. The sensor sits between the bridge saddle and base on the 1st (E) string side, with shims provided for tighter bridge gaps.

• Compatible With: Mandolin (8 strings, 4 courses) — purpose-built for the instrument's string layout
• Mounting System: Cork-padded adjustable clamp with soft suede cushioning — protects finish, no permanent modification
• Package Includes: Manual, mounting kit, USB-C cable — everything needed to install and start playing
