Kopul CMCS-1 Passive 3.5mm Microphone Combiner/Splitter

Offering superior sound quality compared to conventional adapter cables, the Kopul CMCS-1 lets you easily capture sound from two 3.5mm microphones into your DSLR camera or camcorder in discreet mono or combined stereo while bypassing the hassle of a dangling adapter cable.

This simple and lightweight solution utilizes a shoe mount for effortless attachment to your shooting rig, and it features dual mono inputs for external microphones and a 3.5mm stereo output, making connectivity uncomplicated. The onboard switch allows the CMCS-1 to transmit a mixed stereo signal or two individual mono signals to any DSLR camera or camcorder with a 3.5mm input.

The compact and featherlight CMCS-1 is ideal for recording dialogue, narration over ambient sound, or stereo soundscapes and is so straightforward to operate, it will improve your audio without any interruptions for your workflow. Since the CMCS-1 is passive, it requires no batteries or special source of power.

Kopul's CMCS-1 allows you to add two external microphones to your camera rig. Use two lavalier mics when you're recording dialogue or a lavalier and a camera-mountable microphone for recording a narrator with some ambient sound.

There's nothing like rich audio to enhance a video production. The wide 20 Hz to 20 kHz frequency response means the CMCS-1 can transmit detailed and accurate sound to your camera.

The CMCS-1 couldn't be simpler to use. Its passive design means no power source is necessary. All you do is plug in your 3.5mm microphones, connect the included 3.5mm cable to your camera's audio input, and you're ready to record.

When you select mono mode, the CMCS-1 combines both mic inputs to a mono signal and outputs this mono mix identically to two channels. Since the two mic signals are married together, you can tweak the level, EQ, or compression of the combined signals in postproduction.

When you select stereo mode, the CMCS-1 splits the two signals and outputs them to separate channels. This is ideal if you want the flexibility to alter the volume, EQ, compression, and panning on each individual track in postproduction. It's also a great option if you want to record a stereo soundscape.

The CMCS-1 attaches directly to your camera's hot/cold shoe. Weighing less than two ounces, the CMCS-1 is featherlight. You might not even know it's there.

The CMCS-1 is outfitted with a 1/4"-20 mounting socket so you can conveniently mount it on a tripod or onto your camera rig.

The CMCS-1 comes with a coiled 3.5mm TRS cable, which extends from eight to 30 inches. It features gold connector plating and OFC (oxygen-free copper) shielding to maintain the purity of your signal.
