Page 1: ...is 150 ohms Connection is by standard XLR male connector OPERATION Preamp connection A standard balanced XLR can be used for preamp connection The preamp should be a high quality low noise design with 2000 ohms differential input impedance or higher and be capable of up to 60 dB gain Phantom power is not required Figure 8 setting Most ribbon microphones exhibit a figure eight polar pattern The fro...

Page 2: ...sure pressure gradient microphone Hyper cardioid exhibits a moderate proximity effect not as much as figure eight This occurs only from sources close and in front The middle setting of the bass cut is calibrated for flat response at 300 mm source distance Maximum clockwise setting can be used for additional bass cut if desired Omnidirectional setting As the name implies this setting gives the broa...
