The E524D incorporating 2 electret condenser capsules in an XY 90°
arrangement. This popular arrangement provides easy to achieve
stereo Hi-Fi result. Suitable for choir, orchestra, drum sets, solo
instrument or chamber music recording, with good background and
spacious capture.
Cardioid left and right channels emphasis on-axis sound and
suppress rear bound sound that brings the on-axis performance to the
audience and captures minimum direct sound from audience seats.
Matched capsules is vital for stereo microphone, XY arrangement
picks up most sound around axis that demands uniform polar
response across frequency bands in order to reproducing nature
sound. The matched capsules on E524D enable the user to record
nature stereo sound easily.
The E524D's low inherent noise and high sound pressure level allows
to record in very quiet background noise and sustain very high playing
level. The power source can be internal battery or external phantom
power. The package including an XLR5F to 2 XLR3M cable that
connects both channels to the recording device or mixer. Phantom
power to both channel shall be turn-on at the same time. The E524D
works with 9 to 48VDC. The internal battery is ok to leave it in the unit
when using phantom power. The battery can be a automatic back-up
power for phantom power. Phantom power provides better operating
condition, and user don' t need to worry the battery capacity.
The 1.5 V battery is an extremely convenient tool for field
assignments, with the same frequency response and same high SPL
ability.
A blue LED power indicator shows the power condition, it will flash
once during power-up. When the microphone doesn't work or signal
become weaker, it is the time to replace with a new battery. Please
insert the battery according to the polarity indication. When the
microphone is not in use, please switch off the power switch to save
power. If the microphone will not be used for an extended period,
please remove the battery to prevent leakage damage. A good quality

When use the microphone at outdoor, be careful excess handling
noise and wind noise. Same as other condenser directional
microphone, E524D is sensitive to wind, so please place the included
foam wind screen to reduce the wind noise when use the microphone
exposed to windy environment. To reduce shock noise, please refer to
the extended selections of accessories from Superlux.
Applications
— For drum sets, place the E524D above the drummer's head and
pointing toward the drums. Very easy to achieve stereo drum pick-up.
— For recording choir in a studio or stage. Please the microphone at the
middle of the performers, arrange the distance to be as uniform as
possible. Please refer to the "Consideration of distance" for future set-up
reference.
— For recording piano, place the E524D to the opening of the piano and
move around for your sweet spot.
— For duet, trio, quartet, quintet… place the microphone at the center
and equal distance with direct view to all performers.

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. E524D work with 9 to 48VDC
phantom only and 1.5VDC battery. Please make sure your sound system
provide adaquate power to the microphone.
About Frequency Response
Flat
Suitable for working a t control le d environ me nt , or for acoustic
meas uremen ts . Alth ou gh peo pl e persui t flatne ss , but for non eprofessionals, 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.

Directivity
Select or set the directivity of your microphone for stereo recording, for
various music instrument, vocal, speech, and environmental sound pick-up.
Pair of spaced omni for A/B stereo, pair of near coincident cardioid for ORTF,
and pair of coincident XY for Blumlein stereo.
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 advantages which is not good for speech.
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.
