Description
The Adastra COM41 is a dynamic paging microphone built for public address work. It uses a moving coil dynamic capsule, so it runs happily without phantom power and connects straight to a standard XLR channel input. The flexible gooseneck stem terminates in an XLR plug, letting you angle the head to suit whoever is speaking.
You can use the microphone on its own or mount it onto the supplied die-cast base unit, which has a latching on/off switch for hands-free paging announcements. The cardioid polar pattern picks up sound from the front while rejecting noise from the sides and rear, which helps keep announcements clear in busy rooms. Frequency response runs from 50Hz to 12kHz, a range suited to speech rather than music, and output impedance sits at 600 ohms or below for easy matching with mixers and mixer-amplifiers.
In the box you get a foam windshield (windscreen in US terms) to cut breath pops and plosives, plus a 3m balanced XLR-to-XLR lead for connecting to your mixer or mixer-amplifier. Assembled with the base unit, the COM41 weighs 942g and measures 430 x 136 x 107mm, giving it enough desktop presence to stay put during use. Sensitivity is rated at -53.2dB ±3dB. It is a straightforward choice for reception desks, schools, shops and any setting that needs reliable spoken announcements over a PA system.

Frequently Asked
Does the COM41 need phantom power?
No. The dynamic moving coil capsule works without phantom power, so you can plug it straight into a standard XLR input.
What is included with the microphone?
It comes with a die-cast desktop base unit with a latching on/off switch, a foam windshield and a 3m balanced XLR-to-XLR lead.
Can I use it without the base unit?
Yes. The gooseneck stem ends in an XLR plug, so it can connect directly to an XLR channel input, or you can mount it on the base for paging.
What is the polar pattern?
The COM41 has a cardioid pattern, picking up sound from the front and rejecting noise from the sides and rear.
Is it suitable for music?
It is designed for speech and paging. The 50Hz to 12kHz frequency response suits spoken announcements rather than music recording.
How do I connect it to a PA system?
Use the supplied 3m XLR-to-XLR lead to run from the base unit or microphone into your mixer or mixer-amplifier.
