Introduction

Thank you for choosing Senal.

Senal’s CX-series Professional Boundary Microphones are sleek, low-proﬁle microphones

that are designed for capturing voices. Both omnidirectional and cardioid models are

perfect for video conferences, lectures, and meetings.

The CX-series microphones integrate into most AV conferencing systems or sound

systems. Balanced output minimizes unwanted RF interference and noise, even

over long cable runs, and a high-pass ﬁlter minimizes room noise and low-end

rumble. The microphones’ low-proﬁle design offers an inconspicuous appearance

and an unobstructed view. Rugged metal housing protects the mic capsule, and the

nonskid padding keeps the microphone stable on a tabletop or lectern.

Instructions

Setting Up

To set up your room with omnidirectional or cardioid CX

microphones, refer to the illustrations below.

Cardioid Polar Pattern

The CXBM-620/C rejects off-axis noise. Use it in rooms with

inadequate acoustic treatment or in spaces where background

noise is problematic. The CXBM-620/C will capture the voice of the

person sitting directly in front of it while it minimizes room noise

and reverberation.

Omnidirectional Polar Pattern

The CXBM-620/O microphone picks up sound in a 360-degree

pattern. Use it in quiet rooms with adequate acoustic treatment.

Microphones set in the center of the table will pick up all

participants seated around it.

Instructions

Using the CX Boundary Microphone

Each application of the CX Boundary Microphone will be slightly different. The following

scenarios cover frequently used setup.

Live Lecture/Sound Reinforcement

Ideal in an auditorium or house of

worship where a voice needs to be

ampliﬁed for an audience.

Note: CX-series microphones

need phantom power in order to

operate.

Video and Audio Conferencing

CX-series microphones are

compatible with most audio and

video conferencing systems. Refer

to the conferencing system’s user

manual for setup instructions.

Powering the CX Microphone

The CX-series microphones operate on phantom power. Once connected to the power

source, the CX Boundary Mic is ready to work.

Important! When integrating the CX Boundary Mic into a video or audio conferencing

system, or using it with a mixing board, make sure that phantom power is enabled.

High Pass Filter

Activate the High Pass Filter when using the microphone in rooms with inadequate

acoustic treatment or constant noise from air conditioning, fans, or lights.

To roll off low frequencies, use the tip of a pen or a similar pointed object to switch the

high-pass ﬁlter to the on position.

Muting

CX-series microphones are equipped with an easy-touch membrane mute button. To

mute the microphone while in use, press the mute button. The indicator LED will turn off

to show that the microphone has been muted.

Press the mute button again to resume operation.

Problem Solution

The microphone

is connected, but

there’s no sound.

• Make sure that both XLR connectors on the cable are fully inserted into the

plugs on the microphone and input device (conferencing system or mixing

board).

• Make sure you are connected to an XLR port with phantom power, and that

the phantom power is turned on.

• If the indicator LED is off, touch the mute button to unmute the micro-

phone.
