PRO238MKII handheld large diaphragm condenser microphone is
based on the superior performance, and improving the frequency
response, lower handling noise, and mechanical structure. Modular
design makes it easy to remove/restore the capsule. While the
hidden low cut filter switch inside the chamber can be protected
from mis-operation, and let the artist perform comfortably with the
great holding feeling of the PRO238MKII.

Wide and extended frequency and optimized damping, this
cardioids PRO238MKII exhibit nature and lively sound. A best
microphone for live sound, broadcasting, and recording.

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

Directivity

Cardioid

Picks up most signal on axis. Rejects side and picks up least to the back. Suitable for
live sound re-inforcement. Apparent proximity effect and most singer likes to take this
bass boost advantageswhich is notgood for speech.

MS131E

Adjustable

boom stand

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. PRO238MKII work with 9 to 52VDC
phantom only. Please make sure your sound system provide adaquate power
to the microphone.

About Frequency Response

Flat

Suitable for working at controlled environment, or for acoustic
measurements. Although people persuit flatness, but for none­professionals, it is a challenge to makes it works as expectation.

Popular curve response

Based on years of practical experience of pro users. There are curves to be
build for various applications, so that it is very simple to use the
microphone for the purpose. Limiting bandwidth, and emphasing are typical
skill.

Variable response

Incorporating switchable filters to elliminates interference, such as sub­sonic filter to cut air-conditioner and floor vibrations. And allows full flat
when used in controlled environment.

Distance to source

Close miking or distant miking sound very differently. Vocal recording or
live performance practice close miking mostly. Suitable proximity effect is
one desired target, and lower feedback problem is another factor for live
sound application.

While distant miking is common practice for recording, especially stereo
pair recording with large group of performers, such as orchestra or choir.

Distant miking generally picks up less bass section with pressure gradient
type of microphone (cardioid, figure-8, shotgun...) due to acoustic nature
and lack of proximity effects.

Rich bass with distant miking can be recorded with pressure type of
microphone (Omni), which performs the same frequency response with
close or distant pick-up.

Mounting the microphone

Pressure gradient microphone is very sensitive to vibration. Suitable shock
mount for high performance microphone is necessary for extreme low noise
recording. Sturdy stand can set the microphone excatly at the sweet spot
and keep it there. Choose heavy duty microphone stand for studio
condenser microphone which weights much more than handle microphone.

Superlux provides wide range of microphone stands for various demands.
Big Foot Willie is specially developed for large condenser microphones that
able to support 2 large microphones with stereo bracket for single point
stereo recording.

Extension foot on all the 'E' versions serve to mount heavy studio
microphone in limit space live sound applications.

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.
