Product Description
The Bosch PLE-1ME240 amplifier is rated at 240 watts, with outputs available on 100 volt line as well as 4 ohm.
Four switchable mic / line balanced inputs are provided and phantom power is also available for condenser microphones.
Input 1 can be activated by contact closure on a push to talk paging mic, and this can take priority over all other microphone and music inputs. There is also a pre-announcement chime built in.
- A separate music input with volume control is also available.
- 4 microphone / line inputs, plus music source input
- Announcement only output, 3‑wire volume override
- Also available in 60 and 120 watt versions
- 2‑tone chime
