Introduction
This manual was prepared by Sonic Distribution USA LLC to be used in conjunction with
sE Electronics products. Congratulations on purchasing your new sE microphone! Used
with care, it will provide you with many years of reliable service. By combining the
expertise of manufacturing and design engineers with the listening skills of musicians,
sE is able to produce mics that give exemplary audio performance in a variety of
recording situations. sE is a US company with its own manufacturing facility in
Shanghai, China, ensuring affordable prices and a high level of technical performance.
sE does not buy or sell microphones from or to other companies. If it doesn't say sE on
the mic, it is not an sE microphone! Every sE mic is designed from the ground up to fill a
specific need and is assembled using high quality parts. All mics are built in a modern
manufacturing facility that uses the latest precision machines in combination with a
skilled and specially trained assembly staff.
Care and Use of Microphones
General
Most of the operational requirements of this microphone follow common sense practice
for electrical devices in general. Do not operate the mic in excessively damp
environments or where accidental contact with water is a possibility. Do not use solvent
based products to clean it as the finish may be damaged. Always ensure that the
electrical system into which the microphone is plugged is grounded in compliance with
the local electrical wiring code. Condenser microphones are precision instruments and
may become damaged if dropped onto a hard surface. In case of such damage, please
contact an authorized sE service agent. Attempting to repair the microphone yourself or
any attempted repair by a non-authorized service agency will void the warranty.
Safe Use of High Voltage Tube microphones
All sE tube mics operate at high voltages to supply optimum power to the tubes. The
power supply must always be connected with the included power cable to a properly
grounded outlet. NEVER attempt to open the mic or power supply when they are
connected to power as contact with the voltage inside could be fatal.
Tube Replacement
With proper care and use, the tube in your sE microphone should provide you with many
years of optimal performance. If you feel that your microphone is losing sonic
performance, it may be time to replace the tube. NEVER attempt to replace a tube while
the mic is connected and be careful when handling tubes as they can be hot after use.
Unscrew the base of the microphone and carefully slide the body off. Gently remove the
old tube from the socket and replace with a new one. Reassemble the body.

Microphone
User’s Guide
All sE tube microphones use an ECC83A (popularly regarded as a low noise, low
microphonic 12AX7). The Gemini II also has an ECC82 (12AU7) tube, which provides an
actively balanced output. We recommend using only sE Electronics tubes. Damage to
the microphone caused by using tubes other than the recommended types will not be
covered by the warranty. Contact Sonic Distribution for replacements.
Operating Environment and Storage
All condenser microphones are susceptible to a short term loss of performance if they
are exposed to moisture. Store your microphone at a sensible room temperature and
always use it with a pop screen when recording vocals. In addition to preventing
popping on plosive “B” and “P” sounds, a pop screen will help keep moisture away from
the diaphragm. If your microphone becomes noisy (a “rumble” sound) or loses
sensitivity because of exposure to moisture, simply put it somewhere warm and allow it
to dry out for a few hours. Its performance should return to normal. It is also
recommended that all condenser microphones be used in a non-smoking environment
as smoke deposits can build up on the diaphragm over time. This can result in a loss of
performance that can only be remedied by professional cleaning. It is highly
recommended that you keep the microphone in its included cases when not in use.
Cleaning
If the microphone body requires cleaning, use a damp cotton cloth with a little mild
detergent and then dry the microphone body thoroughly. Never let water get into the
grille protecting the capsule and never spray cleaning products or contact enhancing
products where they could come into contact with the capsule as irreparable damage
could be caused.
Warranty
For information regarding your warranty, please refer to the included warranty card.
Common Problems and Solutions
Shockmount will not fit on my stand:
Remove the brass thread reducer.
Distortion or clipping when recording loud sources (drums, guitar amps, etc.):
Engage the -10dB pad when available. If not, the microphone may need to be moved
further from the source.
Low frequency distortion
Engage the hi-pass filter ( ) when available.

Microphone Models:
Gemini II
The Gemini II is a one-of-a-kind, no holds barred piece of microphone
history. The dual tube design means pure tube warmth from an ECC83A
input tube coupled with an ECC82 tube on the output stage in place of
the traditional transformer. The result: an incredibly large, detailed and
intimate sound reminiscent of the classic tube microphones from
decades ago.
Operation
Connect the microphone to the power supply using the 8-pin cable and tighten the
fasteners on both ends. Connect the power supply to a grounded outlet using the 3-pin
power cable. Use a standard 3-pin XLR to XLR cable to connect the power supply to your
preamp and turn it on, ensuring your monitors are turned off or muted. It is
recommended that you let the microphone warm up for a minimum of 30 minutes
before use. For standard low frequency response, use the --------- setting. To attenuate
frequencies below 100 Hz – reducing rumble or other low frequency sounds – engage
the setting. When micing louder sound sources, you may want to engage the
-10dB pad to prevent distortion or clipping of the microphone.

Notes on Recording
Polar Patterns
The polar pattern of a microphone refers to the direction or directions in which it
picks up sound. Some microphones are a fixed single pattern (usually cardioid)
while others offer the ability to switch between multiple patterns. When using a
multipattern mic, it is always a good idea to experiment with different patterns
not only for different directional characteristics but also for tonal variations. Here
are descriptions of 4 basic and common polar patterns.
Cardioid
Figure 8
Omnidirectional
Hypercardioid
Picks up sound from the front and sides of the microphone
with good rear rejection. Exhibits proximity effect.
Picks up sound from the front and back of the microphone
with good side rejection. Exhibits maximum proximity effect.
Picks up sound from all directions. Exhibits no proximity
effect.
Like cardioid with more rejection on the sides, less rear
rejection and more proximity effect.
Note: Proximity effect refers to an increase in low frequency pickup as the source
is moved closer to the microphone, typically within a 2 ft range.

Using Variable Patterns on the Z5600a II
The rotary control switch on the Z5600a II power supply gives you complete
control over the microphone’s 9 available polar patterns. By adjusting this
control, you can alter the ambience and spaciousness of the captured source as
well as the low end response (proximity effect).
Directionality – Starting with the rotary control set completely clockwise, your
Z5600a II will pick up sound from all directions in an omni polar pattern. The next
three positions in the counter-clockwise direction will progressively become more
like a cardioid pattern, rejecting more sound from behind the microphone. The
center position of the switch yields a true cardioid pattern. The next three
positions counter-clockwise after cardioid will progressively become more like a
figure 8 pattern, rejecting more sound from the sides and picking up more in the
front and rear of the microphone.
Proximity Effect – In the omni polar pattern, the microphone will exhibit no
proximity effect. As you turn the switch towards figure 8, the proximity effect will
increase. This is an extremely useful feature that allows you to add or subtract
low end response from sources that are recorded close to the microphone. For
example, if you’re recording a vocal in cardioid and it sounds “thin”, try adjusting
the pattern a few positions towards figure 8. It may give you that extra “oomph”
you’re looking for!
