ZYLIA ZM-1S microphone array

ZYLIA ZM-1S - the 3rd order Ambisonics microphone array with 19 calibrated capsules (MEMS sensors), high-end 24-bit recording resolution and timecode input channel allowing for synchronization of multiple ZM-1S microphones.  

Main features of the microphone: ​

• High quality 360 audio recording - 3rd order Ambisonics
• ​19 microphone omnidirectional digital MEMS capsules distributed on a sphere
• Timecode input channels
• Multiple ZM-1S timecode synchronization
• ​LED ring status indicator informing about recording status
• 48 kHz / 24 bit recording
• USB connectivity making the process of recording easy
• Recording -  ZYLIA Studio PRO plugin, ZYLIA 6DoF VR/AR software or any DAW (Digital Audio Workstation) 

Timecode input

It allows for synchronization of multiple ZM-1S microphones as well as other devices connected to recording system such as video cameras.
Timecode input specification:

• Act as slave device

• Audio line input
  • Full-Scale voltage input (single-ended): 2.1 VRMS
  • ADC sampling rate: 48 kHz
  • ADC bit resolution: 24 bit

Timecode support:       

• SMPTE Timecode Rates: 23.98, 24, 25, 29.97, 29.97DF and 30 FPS
• General audio

Support for multiple ZM-1S recording system (ZYLIA 6DoF VR/AR set)

ZM-1S contains a dedicated chip that allows for the connection of multiple ZM-1S through the USB interface in a single computer. That is, signals from multiple ZM-1S microphones can be aggregated and stream through a single USB interface. It is possible to connect around 20 ZM-1S to a single USB 2.0 interface. However, if a computer has more USB controllers then it is possible to aggregate more signals. In that case, the only limit for connecting ZM-1S is hard disk speed. For modern SSD disks, it should be possible to record more than 150 ZM-1S connected to a single computer.
Typically, each USB port on laptops has a dedicated USB controller.

Mounting options

ZYLIA ZM-1S is equipped with a tripod. The device itself has 1/4" inner thread (compatible with camera stands – picture on the left side). Set includes also 5/8" to 3/8" adapter (inserted into the tripod) which is compatible with standard microphone stands (picture on the right side).

ZYLIA ZM-1S has a detachable stand. You can disassemble it using 3/16 inch hex key. To assemble it back, simply insert stand in the device (you will notice positioning incision), then insert the screw and use a hex key to screw it.
