Add a second cordless microphone to your Expedition XP310w or XP312w PA system with the Samson Concert 88a Wireless Handheld Microphone System. Ideal for singers, DJs, and presenters, this system features a handheld microphone that inhibits feedback and a receiver module that conveniently and easily installs in the back of your Expedition PA speaker.
With up to 100 available frequencies and simple syncing via IR, you can quickly get started and find a strong channel. Two AA batteries (available separately) will power the microphone for up to eight hours, and the mic's power switch doubles as a handy mute function. If you move beyond the system's 100' line-of-sight operating range, the integrated tone key mitigates undesired signal transmission.
As a frequency-agile wireless system, the Concert 88a offers up to 100 frequency presets to help you achieve reliable signal transmission. By operating from 542 to 566 MHz in the UHF spectrum, it avoids interference from Bluetooth and Wi-Fi signals.
Two AA batteries can power the transmitter for up to eight hours of operating time. Use the power switch to mute the mic between performances or turn it off for battery conservation.
Beneath the battery cover, you'll find a plastic screwdriver for adjusting the transmitter's input sensitivity. Generally avoid the maximum gain setting as it can cause distortion when the mic is used on loud sources.
The backlit LCD screen shows vital information including the selected channel and frequency as well as AF and RF levels.
Press the up/down buttons to choose a channel, then use the set button to sync the transmitter to the same channel.
