RCF ZM 21246 Bölge 240 Watt Merkez Ünite
ZM 2124 is the system main unit that includes a preamplifier with 6-zone selection and a built-in 240W amplifier. It is mostly indicated for small systems, where the required power per zone is limited.
It has input connectors for sources and can manage priority and route the two buses to the system zones. It includes an output level control for each of the 6 zones powered by the internal 240W amplifier. An additional external amplifier is needed to keep the music programme in zones not involved by paging.
- Dual-bus system architecture
- System Paging consoles input for up to 6 selective devices daisychained, aux input and overall emergency input on precedence primary bus
- 4 inputs of which 2 microphone and 2 universal, 3 selectable aux inputs with individual volume and tone controls with configurable priority on secondary bus
- 240W constant voltage power amplifier with VU-meter for output signal level and overload indication.
- Auxiliary external amplifier input and output terminals to manage primary and secondary buses independently
- Volume attenuators and switches with indicators to send or not the secondary bus program (i.e. music) on each of the 6 speaker line outputs
- Link to connect up to eight ZE 2200 6six-zone expansion units so to built-up paging systems in excess of 50 zones.
- Dedicated wall mounting system remote control allows you to remote the main commands available on the master unit
- Priority indicator to show when any system priority circuit has been triggered
- Selectable chime generator is available on announcements
- GPI and GPO logic ports are available for interface purposes with third parties systems and for monitoring feedback.
- RS 232 port for FW upgrade and communication/interface purposes
- Power supply AC or DC24V, 3U 19" rack mounting
