Shure Brothers SLX24/SM58-L4
Overview
Shure SLX24/SM58-L4
Handheld UHF System, SLX4 and SLX2/SM58
The Shure SLX24/SM58-L4 is a UHF system that includes a SLX4 wireless microphone receiver, as well as a SLX2/SM58 handheld wireless microphone transmitter combined with a SM58 microphone capsule. Both components operate on the L4 frequency band of 638 to 662 MHz.*
SLX2/SM58-L4
The Shure SLX2/SM58-L4 is a professional dynamic handheld wireless microphone transmitter fitted with the legendary SM58 cardioid vocal microphone, tailored to deliver warm and clear vocal reproduction. It is designed for seamless integration with the SLX4 Wireless Receiver.
The SM58 microphone capsule features brightened mid-range and bass roll-off, and a built-in spherical wind and pop filter.
SLX4-L4
The diversity design of the SLX4-L4 receiver allows dual receiver circuits and antennas to compete for the strongest possible reception. The SLX4-L4 features XLR microphone level and 1/4" phone line level outputs. A comprehensive LCD display provides Frequency, Group, and Channel information, as well as locked/unlocked status, and battery strength.
This UHF receiver brings unprecedented ease-of-use with Auto Frequency Selection and Auto Transmitter Setup. Including rack hardware and detachable antennas, it's ready for installation right out of the box.
* Important notice: In the US, the FCC requires that the frequency of this device be set between 652 to 662 MHz. 638 to 652 MHz cannot be used. Foreign customers must check that the frequency band 638 to 662 MHz is unrestricted before purchasing.
