PRA628 MKII
PRA628
MKII
Unidirectional Instrument Microphone
The PRA628MKII With “flat-profile” design is an optimized model of the
PRA628. Side address mounted capsule for miking guitar amps face on and
extremely close to the signal source. Super-cardioid pick-up pattern isolates the
main sound source while minimizing background noise. With extended
frequency response, deeper to the lower bottom range, higher SPL capacity and
supercardioid directivity with high gain before feedback, it is suitable for guitar,
bass amplifier pick up or instrument reinforcement. Also suitable for drum
miking, particularly toms, where the microphone’s profile allows the capsule to
be positioned close to the drum skin.

• High dynamic range and extended
frequency response
• High SPL up to 150 dB SPL
• Flat pop screen design, closer to
the sound source
• Universal clamp and mic clip
included
• Tailored frequency response to
reproduce the instrument natural
sound
• Sturdy metal body
• For guitar amps captured medium attack sound profile with balanced sound,
place PRA628 MKII around 15-30 cm (6-12 in) away from speaker, centered
directly in front of speaker cone.
• For percussion instrument captured most attack sound profile with natural
sound, place PRA628 MKII 2.5 to 7.5 cm (1 to 3 in) above rim of top head of
drum. Aim mic at drum head.
• For higher gain before feedback and lowest background noise, the microphone
shall be pointed directly to the sound source.
• The sensitivity of a supercardioid microphone is highest on axis and lowest at
120 to 135 degrees.
• To avoid interference between multiple microphones, each sound source shall
be picked-up by one microphone, use as less microphones as possible in one
space, or turn-on as less microphones as possible at the same time.
• To reduce crosstalk between microphones, an 1:3 guide line shall be follow:
The distance between microphone A to the sound source A is “1” , the distance
between any other microphone to the sound source A shall be more than 3 times.
• Reflecting surface affect sound as well. Beware of these surfaces such as wall,
table, or floor. Place the microphone away from the hard surfaces or directly
contact these surfaces to form a pressure zone microphone.
• When using the microphone outdoor or in windy environment, additional foam
wind screen helps to reduce wind noise.
• Keep grill pop screen clean to avoid degrading the sound quality. Do not expose
the microphone at high humidity/temperature environment to avoid damage.

General Rules for Use
Proximity Effect
When the supercardioid microphone get closer to the sound source, the low
frequency response is boosted, as so call “proximity effect”. Experience engineer
takes advantages of the proximity effect to improve the richness of instrument
sound or to increase the bass of the instrument as if an extremely high quality
equalizer is used. Same ideas to reduce the bass by increase the distance to
reduce the bass when needed.
Mounting the Microphone
Sturdy drum clamp and stand can set the microphone exactly at the sweet spot
and keep it there. Superlux provides wide range of drum clamps and stands for
various demands. Please check on our web site www.superlux.com.tw to get
more information.
Maintenance
Microphones shall be kept in low humidity environment for best sound
performance. Store the microphones in air-conditioned room or dehumidifier to
keep away from moisture. Clean air is another important factor. Keep away from
smoking environment to avoid tar residuals.

• The front side of capsule is located at the side with the mark of “Front”
• For guitar amps captured most attack sound profile with emphasized bass,
place PRA628 MKII around 2.5 cm (1 in) away from speaker, centered
directly in front of speaker cone.
• For guitar amps captured sharp attack sound profile with higher frequency
sound, place PRA628 MKII around 2.5 cm (1 in) away from speaker, at the
edge of speaker cone.
