Safety And Maintenance - SE Electronics Gemini II User Manual

Low-Cut Switch
The Low-Cut Switch is located on the front-right side of the microphone, inserting a low-cut
filter at 150Hz when engaged. When switched to the left, the filter is removed for a flat
frequency response. This low-cut switch is useful for reducing wind noise, plosives, footfall
noise or rumble that might adversely affect the recorded signal. Additionally, the low-cut
filter will minimize the proximity effect when "close-miking," i.e. placing the microphone a
very short distance from the source.
Powering
The included floor box contains the outboard power supply for the Gemini II. No phantom power is required
from an interface or microphone preamplifier.
Before powering on, connect all required cables (IEC to power, XLR to preamplifier or interface, and 8-pin
cable from floor box to microphone). Then turn the power on via the switch on the back of the Gemini II floor
box.
For best performance, we recommend allowing approximately 15 minutes of "warm up" time before
recording. This allows the tubes within the Gemini II to heat up and stabilize and reduces the risk of unwanted
noise or distortion on your recordings.

Safety and maintenance

Cleaning the microphone
The microphone should only be cleaned with a dry, soft cloth. It is best stored in the supplied wooden
presentation box.
Risk of damage
Do not connect the microphone to any power supply other than the included Gemini II
power supply. Do not apply phantom voltage (+48VDC) from an external interface or
preamplifier. This is the only way to ensure safe and reliable operation.
Risk of damage
Please make sure that the piece of equipment to which your microphone and PSU will
be connected fulfils the safety regulations enforced in your country and is fitted with a
ground lead.
