SEW-ON MOUNTING
MOUNTING THE SM93 PREAMPLIFIER
Use the spring-loaded belt clip to hold the amplifier to a belt, skirt or trouser waistband, or inside pocket.
WINDSCREENS
An acoustic foam windscreen is supplied to help reduce undesirable wind noise associated with outdoor miking.
POWERING THE SM93 PREAMPLIFIER
Power the preamplifier supplied with the SM93 using any phantom supply providing 11 to 52 Vdc, such as the Shure Model
PS1A Power Supply.
SM93 PREAMPLIFIER IMPEDANCE
Use a minimum load impedance of 800 Ω or greater for maximum signal handling and minimum distortion. Load as low as 150
Ω can be used, but a reduction in output clipping level will result. Note that the power supply itself may add loading (3300 Ω in
the Shure PS1A) to the microphone.
USING OTHER PREAMPLIFIERS OR BODY-PACKS
If connecting the 93 microphone to anything OTHER than a Shure wireless body-pack or the preamplifier supplied with the
SM93, make sure it provides a regulated +5 Vdc source (40 µA minimum) at pin 2 of the microphone connector, as shown in
"MICROPHONE WIRING DIAGRAM" Figure.
