ETS CSM8 8" Ceiling Speaker Microphone

The ETS CSM8 8" Ceiling Speaker Microphone combines a pre-amplified omnidirectional microphone and an 8" speaker in one unit. It is designed for flush mounting in acoustic tiles, drywall, or similar surfaces.

This unit operates on half-duplex audio systems only and connects via the ETS SMA1 interface or comparable equipment. Avoid activating both microphone and speaker simultaneously to prevent feedback. The microphone features a low-noise MOSFET pre-amplifier, adjustable gain, and a frequency response from 200 Hz to 16 kHz.

• Microphone peak limiter with 1-second attack and release
• Breakout circuit board with Euro-style connectors for easy wiring
• Speaker frequency response: 200 Hz to 10 kHz
