What is the SM58 best suited to? - It’s an ideal choice for a professional vocal artist in any live performance setting. It is tuned to accentuate the warmth and clarity of lead and backing vocals.
Even in extreme conditions, the SM58 is tailored to target the main sound source while minimizing background noise. It is also very popular with djs and presenters in clubs and in small and large live venues.
Can it withstand the rigours of touring? - Durable construction, a proven shock-mount system, and a steel mesh grille ensure that even with rough handling, the SM58 will perform consistently, outdoors or indoors.
What receiver comes with the SM Wireless Vocal System? - The SM Wireless Vocal System comes with the Analog Wireless Receiver BLX4 that provides improved linearity and frequency response.
The BLX receiver is ready to perform right out of the box and is a great choice for performers who wish to unplug from the wire. It’s also available as a rack-mountable, metal receiver and Dual Receiver.
How many musicians can use this system simultaneously? - Up to 12 compatible channels per group with group and channel scan for easy set-up.
Why internal antennas? - For ideal signal strength, antennas on a wireless system need to be set up in a certain way. The internal antennas on the BLX receiver are already set in this ideal way, offering up to 100 m operating range and optimal signal strength. Additionally internal antennas cannot be broken during setup, use or transport.
Is the setup really that easy? - Yes, with one button you can start the group and channel scan, which gives you the best open frequency. Adjust the transmitter to the same channel and you’re ready to go.
