1. INTRODUCTION
2. KEY FEATURES
Ever since K-array launched its first slim column speaker in 2007, it has maintained its position of leader
of sleek line arrays. With every subsequent product release, the company has perfected its solutions
composed of closely-spaced, full-range sound sources by incorporating its Pure Array Technology.
This same line array technology is now being applied to the latest addition to the K-array portfolio in
a form other than a speaker. The Capture-KMC20 is the smallest line array microphone in the market
featuring PAT technology composed of 8 x 4mm cardioid capsules aligned in a line array configuration.
Given its line array characteristics, the Capture shows a minimal variation of gain with distance. As a result,
the distance between the orator and the microphone is not crucial and he is able to move towards or away
from the mic freely without strongly affecting the volume or audio quality.
The polar response is cardioid in the horizontal plane, and very narrow in the vertical plan, therefore,
when mounted in vertical, not only does the mic not pick up sound from behind, but it’s also insensitive
to sounds that come from above and below, strongly reducing the amount of ambient sound captured.
Being very wide in the horizontal plane, a single microphone can pick up more people and gives maximum
freedom of movement to the right and left without volume fluctuations.
While when mounted in horizontal, the capture is very wide on the vertical plane and very narrow on the
horizontal plane, resulting in capturing only the person in front of the microphone while standing or sitting.
The microphone’s impressively slender frame is shaped from a 6x6 mm solid square brass bar using a
milling cutter with bits less than 2 mm in radius. It’s meticulously pieced together welding 2 mm- and
4 mm- tall capsules to a 0.6 mm-thick electronic board then two 0.3 mm-thick stainless steel grills are
micro-stretched over the frame. The frame is secured in place by two plates screwed one on top of the
other. Finally, all the components are sandblasted to obtain a homogeneous opaque finish and embellished
with an ultra-black ruthenium galvanic bath.
And given its thickness of 6mm, these incredibly thin microphones are impressively discreet and made
with durable premium materials like brass to be used for a variety of applications in conference halls,
boardrooms, houses of worship and TV studios.

7.3 MICROPHONE STAND ACCESSORY
Tighten the extendable stand in the floor base. Insert the microphone in the slot on the top of the
stand and screw it in place using the included screw driver. Adjust the orientation of the stand and the
microphone. Connect the wire from the floor base to the preamplifier. Use an XLR microphone cable to
connect the preamplifier to the mixer and feed it with the 48V phantom power.

8. CONNECTING THE MICROPHONE
Connect the wire coming out from the base to the included preamplifier. Use a three-pin XLR professional
microphone cable (XLR) to connect the preamplifier to a microphone input which provides 48 V phantom
powering.
Phantom supply voltage must stay between 36 to 52 Vdc, providing at least 7mA of current. Voltage
must be positive on pins 2 and 3 of the XLR connector of the preamplifier.
