The PGA58 is designed for speech and vocal applications whereas the PGA57 is specifically designed to meet instrument applications.
There are several differences between the two mics. Here are the most relevant ones: Polar pattern: Beta 58A = supercardioid; SM58 = cardioid Output level: Beta 58A is 4dB hotter than SM58 Handling noise: Beta 58A has less handling noise than the SM58 Grille: Beta 58A has a hardened grille that is very difficult to dent Frequency response: Beta 58A has extended low and high end compared to SM58
The SM58 wireless capsule RPW112 is available for and compatible with all Shure wireless series allowing interchangeable capsules.
Please note that BLX and GLX-D wireless series do not feature interchangeable microphone capsules. For these series the SM58 is available as an integrated microphone capsule design.
SE112: Uses one dynamic driver and does not feature detachable cable
SE215: Uses one dynamic driver and comes with detachable cable and ergonomic earphones housing SE315: Uses one balanced armature driver and comes with detachable cable and ergonomic earphones housing
SE425: Uses two balanced armature drivers and comes with detachable cable and ergonomic earphones housing
SE535: Uses three balanced armature drivers and comes with detachable cable and ergonomic earphones housing
SE846: Uses four balanced armature drivers including subwoofer performance, detachable cable, ergonomic earphones housing and detachable nozzle
The SE215, SE315, SE425, SE535 and SE846 earphones use a cable which is resistant against sweat. These earphones have been designed to resist conditions on stage, which includes a lot of sweat.

The GLX-D Advanced receiver is rack-mountable and features detachable antennas. This allows users to use directional antennas, helping to increase system stability in environments with other WiFi sources.
The GLX-D Advanced Frequency Manager creates a shared group of frequencies for all receivers to use and automatically assigns frequencies to each receiver. If interference occurs, the frequency manager assigns new frequencies without audible dropouts.
No. When running two channels we recommend using the UA221-RSMA antenna splitter to split the incoming antenna signal to the two receivers
No. There is only one series of transmitters. These can be used with GLX-D receivers (GLXD4 and GLXD6) as well as with GLX-D Advanced receivers (GLXD4R).
In an environment with no other WiFi devices you can run up to 11 channels. Under typical conditions (one WiFi channel is active) you can run up to 9 channels. The more WiFi channels active in an environment, the lower the max. amount of channels. Please be sure to use frequency manager.
Group A is optimized for low latency (4 ms), ideal for a channel count of 6 systems, maximum 9.
Group B has a higher stability and a higher latency (7,3 ms), ideal if you experience interference or need to run 9 to 11 systems.
If you are not using the Frequency Manager, then the GLXD4R receiver operates similar to a GLXD4 receiver. In that case, follow the guidelines and best-practices for GLX-D.
If you are using the Frequency Manager, we recommend only one GLX-D standard system.
