The E321 gooseneck microphones are designed with high quality sound
pick-up performance for professional recording, broadcasting, and
conferences. Suitable for human voices, or music instruments.

Uniform directivities across working frequency band, cardioid and super
cardioid directional capsules provides high gain before feedback in live
sound applications. With omni capsule, this microphone provides excellent
sound pick-up with uniform frequency response regardless of the distance
variation, and it provides very clean speech at up-close pick-up.

Works with standard phantom power supply ranging from 9 to 52VDC, E321
works with almost all kinds of professional audio mixing consoles or
microphone pre-amplifiers.

Integral XLR male plug connects directly with standard XLR female socket
for fast, easy and error free plug and play simplicity.

Easy to un-screw
capsules can be
exchanged to different
directivity. E321 comes
with Cardioid capsule.
Choices are super­cardioids and omni.
The part number is

3 interchangeable polar-pattern capsules

AM100E10902AH for
cardioid, and AM100E10902AO for omni.

There are 3 length versions to choose. E321S is the short version, 30cm or
12 inches in length. E321M and E321MSL are the medium version, 45cm or
18 inches in length. E321L and E321LSL are the long version, 60cm or 24
inches in length. All provides single bending section, which allows fast and
easy bending without bouncing back problem. Set it there, and it is there.

E321 supplied foam wind screen that filters out wind blow and allows the
sound to pass through with minimum loss.

Optional gooseneck mounts are available from Superlux, such as HM22,
HM23, HM24 and also desktop bases at your selection.…

Installing the E321

Four mounting methods are possible. Either connect the E321 directly
to a surface mounted 3-socket XLR type connector, or use an optional
accessory HM22 standard mount, HM23 shock mount or HM24 shock
mount with XLR connector to mount the E321 preamplifier housing
below a mounting surface.

To install the E321 below a mounting surface, proceed as follows.

Toinstall theE321 below a mounting surface
with HM22, proceed as follows.

1. Drill a 29.5mm(1 1/6” in.) diameter hole
in the surface on which the Hm22 is to be
mounted. (See figure 7)

2. Center the mounting base on the surface
abovethe hole.

3. Mark the location of the three screw holes in
the mount base, remove the mounting base,
and drill starter holes in the threemarked
places.

4. Unscrew the bottom plastic screw, and insert
the E321 in the mounting base, and then
screw in the bottom plastic screw.

5. Fasten the mounting base and E321 to the
mounting surface using the three supplied
screws.

Toinstall theE321 below a mounting
surface with shock mount HM23, proceed
as follows.

1. Drill a 50.8mm 2 in.) diameter hole

(

in the surface on which the HM23 is to be

mounted. (See left picture)

2. Center the shock mount on the surface
above the hole.

3. Mark the location of the three screw holes

in the shock mount, remove the microphone
and shock mount, and drill starter holesin
the three marked places.

4. Fasten the shock mount to the mounting

surface suing the three supplied screws.

the bottom screw of holding fixture, and
insert inthe the XLR connector and then
screw in the bottom screw to fixthe XLR-F
cable.

Toinstall theE321 below a mounting surface with shock mount HM23,
proceed as follows.

1. Drill a 43mm(1 11/16 in.) diameter hole in the surface on which the
HM23 is to be mounted. (See figure 9)

2. Center the shock mount on the surface above the hole.

3. Mark the location of the three screw holes in the shock mount,remove
the microphone and shock mount, and drill starter holesin
the three marked places.

4. Fasten the shock mount to the mounting surface suing the three
supplied screws.

Knowing your microphone

Superlux provides variety selection of microphones for professionals and amatures. To
know your microphone is the first step to successful result.

Type of transducer

Condenser

Extremely light weight diaphragm, very sensitive to sound. Very small versions
available for hiding applications. High performance condenser microphones are
regarded as standard equipment of recording studios for extreme detail capturing.
Operates with power, such as phantom or battery.

Powering microphone

Condenser microphones work with power. Professional standard is 48VDC phantom
power. Some microphones work with lower voltage as low as 1.5VDC, such as battery
power model. E321 work with 9 to 52VDC phantom only. Please make sure your sound
system provide adaquate power to the microphone.

Using condenser gooseneck microphone

Uni-directional condenser microphone features very high sensitivity at -40dBV/Pa for
high intelligible speech application. Reduced off-axis sensitivity to keep lower
background noise and maximized on-axis sensitivity for highest gain before feedback
in live soundsystem.

User shall keep 15 cm to 40 cm from microphone, and maintain average speech level.
Up close will result excessive bass due to proximity effect which interfere intelligibility.
Maintain their speakingin front of the microphonefor high gain before feedback.

Quality conference microphone incorporating built-in limiter to prevent distortion due
to exciting useror close upspeaker.

Choices of gooseneck for various demands. For aesthetic, single or double bend
goosenecks are better choice over fully bend design. Low bending noise is another
important feature of good gooseneck microphone. User shall not bend the gooseneck
to hard or rush which may generate excessive noise which disturbs the audience.

In most cases, each attendee has his own microphone or share a microphone every 2
attendee. Although there are numbers of microphones in one space which is not a good
criterion for feedback problem, system operator shall keep as less turn-on microphone
as possible for best result. Auto-mixer is a good choice for multiple microphones
installation which limit the number of turn-on microphone at the one time. Advanced
auto mixer features dynamic threshold and auto gain reduction according to the
number of turn-onmicrophones to keep the same system gain.

Wind screen is vital for windy environment such as outdoor or close to air-conditioning
fan.

Keep capsule and wind screen clean for good audio performance.

Maintainence

Condenser microphone shall be kept in low humidity environment for best sound
performance. Store the condenser microphones in airconditioned room or dehumidifier
to keep away form moisture. Clean air is another important factor. Keep away from
smoking environment to avoid tar residuals.
