Dynamic low-Z mics

Silver Bullet Dynamic – low impedance harmonica microphones

The Silver Bullet | Dynamic low-Z mic has at its heart a bulletproof dynamic element of low impedance that provides a lovely rich, fat tone and harmonic content with headroom to enable you to drive the mic’ and produce a classic “blues” sound – with a little help from your amp. The mic’ is low impedance which provides a medium powered microphone that may need impedance conversion (low to high) or pre-amplification for large-venue gigging but is perfect for practice or small-venue performance straight out of the box. Depending on your rig the use of an impedance converter is recommended for maximising output and significantly boosting the power output of this microphone. For example using a Shure A85F “low to high impedance microphone-matching transformer” will provide an additional 24 dB of signal gain. Note that this will also require a mono (female) to XLR (male) converter plug to link to your microphone lead and couple (line 1 and 3 to earth) to the in-line transformer. This or similar impedance conversion is really recommended as it releases the beast in this lovely dynamic mic.

The use of Dynamic mic’s are practically bulletproof while providing a microphone that is rich in tone and performance – perfect for practice or gigging and with proven reliability. The mic’ is low impedance which means it suits a rig with medium and high amp impedance sockets. Silver Bullet Dynamic mic’s are available with and without gain control.
