Shure ROSWELLITE KSM353 - Manual (Page 4)

PERFORMANCE CHARACTERISTICS
The KSM353, like all ribbon microphones, performs optimally with
the least amount of loading on the ribbon element as practical.
The higher the impedance input on the microphone, the better the
low-end and mid-range frequencies are represented in the output
signal. We recommend using preamps with impedance settings of
1000 Ohms or more.
The KSM353 is a low noise microphone. The combination of
its efficient transducer, robust shielding, and custom full-sized
transformer give the microphone a low noise floor and output level
equal to moving coil microphones. Certain ribbon designs have
weaker magnets and less shielding, and require additional gain for
optimum performance. This is not the case with the KSM353. Most
professional level preamplifiers with normal gain and high input
impedance are well suited for this microphone.
The KSM353 is quite natural sounding and does not require color-
ation at the preamp stage for optimal performance. Preamps that
provide simple, transparent gain usually provide the best results.
However, you may prefer a more colored sound, and we encourage
you to experiment to find the right combination that suits your taste.
When addressing the rear side of the KSM353 please remember to
invert the signal polarity.*
