MRM-70S UHF Single Channel Diversity Receiver Module
- Advanced diversity technology for optimum reception quality.
- Preset with 16 auto-scannable frequencies.
- One-touch Scan for a clear, interference-free frequency.
- One-touch ACT™ syncs the transmitter and receiver frequency automatically.
- Easy-to-read LED channel display.
- Interference warning indicator.
- "Sensitivity" adjustor can be adjusted to minimize interference.
- Dual "PiloTone & NoiseLock" circuits minimize interference.
- 5-segment RF and Audio meters.
- Modular design allows easy installation and replacement.
- When MRM-70S / MRM-70D is installed, master level control enables volume be wirelessly controlled by an ACT-32HR transmitter microphone instead of a separate remote. (MA-708 & MA-808 portables)
