The Black Hole Series Microphones Owner’s Manual www.jzmic.
Safety Precautions Detailed safety precautions: Please read all safety precautions and operating instructions before attempting to operate the unit. Keep all safety precautions and operating instructions for future reference. Water and moisture: Condenser microphones are extremely moisture-sensitive. Never use your microphone in close proximity to water (e.g. bath tubs, wash basins, sinks, washing machines, pools, etc.). Damage: Take care not to drop your microphone as this can lead to severe damage.
Always turn down the levels (means no sound) of the microphone pre-amp or console while connecting or disconnecting the microphone to avoid possible damage to your speakers or headphones. The Black Hole series microphones set up 1. Take the microphone out of the box. 2. Replace the shipping screw from included shock-mount with the included thumb screw. To unscrew the shipping screw use either the included thumb screw or appropriate screw driver, or you can use the coin if you have one with you.
Installation: Before mounting your shock-mount on a microphone stand replace the shipping screw from the shock-mount with included thumb screw for easy operation. Squeeze the shock-mount and carefully put on the microphone. There is removable adapter in microphone`s swivel mount which lets you mount it on mic stands with either metric (Europe) or imperial- gauge threads (North America). Make sure that your microphone is standing safe on the shockmount.
The Golden Drop Capsule (GDC) The soul of each and every Black Hole Series microphone is the unique Golden Drop Capsule (GDC) technology, created by JZ Microphones’ founder and lead designer Juris Zarins. Using this innovative technology, the capsule’s diaphragm is lighter; therefore, it moves and gets to its default position faster than the same capsule’s diaphragm without Golden Drop technology. It gives more clarity, precision, fewer colorations and distortions in frequency response.
instead it just lovers the signal level allowing capsule to handle high SPL`s and keeping the signal unaffected. Important is that in most cases the microphone can handle high signal level but the microphone preamplifiers can`t. That is why we care about your preamplifier and made a BH1s and BH3 microphones with pad option. BH series microphones share basically the same electronic parts. Every BH series microphone except BH1s use component selection with tolerance 1.
