Thank you for choosing this K-array product!
To ensure proper operation, please carefully read this owner’s
manual and safety instructions before using the product.
After reading this manual, be sure to keep it for future reference.
Should you have any questions about your new
device please contact K-array customer service at
[e-mail] or contact the official K-array distributor
in your country.
Composed of 16 x 6 mm electret condenser cardioid
capsules aligned in a line array configuration, the KMC50
has been designed for voice and instrument amplification
as well as for capturing environmental sound with the
precision of a perfect directive microphone.
Thanks to the Pure Array Technology, the KMC50 polar
response is cardioid in the horizontal plane and very narrow
in the vertical plan, which allows for a precise and clean
concentration of the signal capture.
Achieving higher directivity with the Capture-KMC50 by
linking up to 4 units to create an impressive continuous
steerable array allows users to explore new microphone
techniques and applications.

Getting Started
Unpack the Capture-KMC50 microphone and its accessory kits.
A preamplifier kit is required! Select either the K-PREMC01
or the K-PREMC02 preamplifier kit according to the number
of microphone units and the configuration you want to make.
Single unit
1. Assembly the Capture-KMC50 microphone and the female adapter
with cable and MiniXLR connector supplied in the K-PREMC01
preamplifier kit (see Single-unit microphone assembly, page 6).
2. Plug the top cap on the Capture-KMC50 microphone.
3. Connect the MiniXLR connector to the K-PREMC01 single unit
preamplifier.
4. According to the type of application:
• Stand mounting applications: mount the K-BRK50 bracket on the
Capture-KMC50 microphone assembly and set it on the Rycote
InVision INV-1 adapter.
• Surface mounting applications: slip the Capture-KMC50
microphone on the foam brackets: four screws are provided for
fixing the foams to the surface.
5. Plug the microphone to the input device and switch on the Phantom
power (see Connecting, page 9).
Multiple units
1. Assembly the Capture-KMC50 microphones and the KMC50-
JOINT according to the desired array configuration (see Multiple-unit
microphone assembly, page 7).
2. According to the type of application:
• Custom bracketing: plug the female adapter with cable and MiniXLR
connector supplied in the K-PREMC02 preamplifier kit to one end of
the Capture-KMC50 microphone line array.
• Suspended microphone line array: plug the K-FLYM5 flybar to one
end of the Capture-KMC50 microphone line array.
3. Plug the microphone cap on the opposite end of the Capture-KMC50
microphone array.
4. Connect the MiniXLR connector to the K-PREMC02 preamplifier.
5. Connect a reliable 5 V 500 mA power supply to the K-PREMC02
preamplifier (see Connecting, page 9).
6. Plug the K-PREMC02 microphone preamplifier to the input device and
switch on the Phantom power.

Assembling
In order to operate the Capture-KMC50, the microphone and
the proper preamplifier kit – either the K-PREMC01 or the
K-PREMC02 – must be assembled.
Single-unit microphone assembly
The K-PREMC01 preamplifier is designed to drive a single
Capture-KMC50 microphone unit.
The K-PREMC01 single unit preamplifier kit comprises the
top cap and the bottom adapter with cable and MiniXRL
connector. Follows the images below to assemble the
microphone.
The connectors on top and at the bottom of the
microphone are shaped according to the unit
orientation.
Set the microphone cap and the adapter with cable
at the opposite ends of the unit.
Plug the miniXLR connector to the K-PREMC01
preamplifier.

Multiple-unit microphone assembly
The K-PREMC02 preamplifier is designed to drive up to
4 (four) Capture-KMC50 microphone units in line array
arrangement. The KMC50-JOINT accessory is needed to
joint multiple microphone units.
The optional K-FLYM5 flybar is available for ease the aiming
of the microphone array.
The connectors on top and at the bottom of the
microphones are shaped according to the unit
orientation.
Connect two microphone units to the KMC50-JOINT
accessory and gently tighten the 2x M2 screws.
In order to plug the first unit to the K-FLYM5 flybar, the
Capture-KMC50 microphone shall be oriented upside-down
with the plug connector on top.

It is possible to connect up to 4 (four) Capture-
KMC50 units using 3x KMC50-JOINT accessories
achieving a maximum of 2-meter-long (6.5 ft)
steerable microphone line array.
Place the cap at the bottom unit and connect the
microphone line array assembly to the K-FLYM5
flybar. Gently tighten the flybar M2 screw to secure
the assembly.
You can possibly angle the joint in order to achieve
the desired microphone array pick-up coverage.

Connecting
The Capture-KMC50 microphone needs the 48V phantom
power supply.
4
Use only the K-PREMC02 preamplifier for powering
multiple microphone units.
K-array assumes no liability for any damage
caused by a defective power supply.
Always mute the sound reinforcement system
before switching on the power supplies
Use only high quality 5VDC, 500mA power supply
for guarantee pristine audio.
A further 5VDC 500mA power supply unit (not provided)
is needed to guarantee proper microphone operating.
The auxiliary DC power supply can be connected to the
K-PREMC02 preamplifier either via a MicroUSB connector or
using a XLR connector.
When the phantom power
is supplied, the LED on the
K-PREMC01 preamplifier lights up.
When more than one Capture-
KMC50 microphone unit
is employed in line array
configuration, the K-PREMC02
preamplifier must be used AND
a further DC power supply must
be connected to the K-PREMC02
preamplifier.
