Four Microphones for Vocal and Instrument Capture

The bundle supplies four Audio-Technica Pro 70 cardioid lavalier microphones built for clear mid-range reproduction of voices and acoustic instruments. Each unit uses a focused pickup pattern to reject off-axis sound and improve gain before feedback in live or studio settings. A low-frequency roll-off switch cuts rumble from wind, handling and electrical hum. The pack suits presenters, musicians and content creators who need multiple matched channels.

Cables, Power and Cleaning Accessories Included

Four 10 Ft XLR cables connect every microphone directly to mixers, preamps or cameras without extra purchases. Four UM3 power supplies are provided, each accepting a single AA battery or external phantom power for flexible placement. A dedicated charger and four sets of AA batteries keep all channels running. A microfibre cloth and microphone cleaner help maintain capsule hygiene across repeated use.

XLR Interface and Battery Power Constraints

The 3-pin XLR output requires a compatible input on the receiving device; no wireless or digital alternative is included. Each UM3 supply operates on one AA cell, so runtime depends on battery capacity and the phantom-power draw of the connected preamp. The cardioid pattern reduces rear sensitivity but does not eliminate loud ambient sound arriving on-axis. Buyers needing wireless freedom or more than four simultaneous channels must look elsewhere.

Questions about this item

How long do the AA batteries last before I need to replace them?

The UM3 power supply runs on a single AA battery or external phantom power, so battery life depends on the cell you choose and how long you record each session.

What limits how many of these lavaliers I can run at once?

Each Pro 70 needs its own XLR input and phantom power source, so the number of free mixer channels or camera inputs is the practical limit.

How much heat or noise does the UM3 power module add during all-day use?

The UM3 supply is a small battery-powered module that generates no audible fan noise and negligible warmth even during continuous operation.
