RCF ZM 2124 - 240W 6 Zone Mixer/Amplifier in Black Finish

The RCF ZM 2124 is a highly capable 240W, 6-zone mixer/amplifier, designed for small to medium-sized audio systems requiring a flexible and scalable solution for zone control and audio distribution. This versatile unit is the master unit of the ZM 2000 system and combines a preamplifier with a built-in 240W amplifier. The ZM 2124 is equipped with dual-bus architecture, making it ideal for environments where selective paging and music distribution are required in multiple zones. It is perfect for applications such as public address systems, business music systems, and integrated audio setups in offices, hotels, and retail environments.

At the core of the ZM 2124's functionality is its dual-bus system, which helps segregate the audio signals between paging and music sources. The first bus is dedicated to selective or all-call paging, while the second bus is used for distributing music or other audio signals to designated zones. The unit provides toggle buttons for turning the music bus on or off in each zone, allowing for flexible zone management. This means that zones needing only paging can be kept separate from those requiring music audio, ensuring that both functions can operate simultaneously without interference.

For enhanced integration and flexibility, the ZM 2124 features logic inputs and outputs (GPI/GPO), enabling easy interfacing with external devices, such as remote controls and alarms. It is also capable of connecting to up to 8 additional ZE 2200 zone expansions, extending the system's reach to more areas when required. This makes the ZM 2124 ideal for larger systems that require multiple zone control but also need a compact, powerful core unit.

In terms of audio handling, the ZM 2124 supports a total of 9 input channels, with 6 balanced mic/line inputs and 3 unbalanced stereo inputs. These inputs offer flexibility to connect various audio sources, such as microphones, CD players, or tuners. It also provides an emergency audio input to ensure that important messages can be broadcast in case of an emergency. Each of the 6 zones powered by the internal amplifier has its own output level control, allowing for precise volume adjustment in different zones. For areas that do not require paging but still need music, an additional external amplifier can be connected to handle those zones.

Additional features include a selectable chime generator and a dedicated paging input for connecting up to 6 BM 2006 paging consoles. The system supports Music on Hold and has programmable general-purpose inputs and outputs (GPI/GPO) to control various functions remotely. The unit also includes a front panel control for ease of configuration, along with tone controls for fine-tuning the audio quality.

With a frequency response of 50 Hz to 20 kHz, the ZM 2124 ensures high-quality audio output for both paging and music signals. The unit's convection cooling system provides efficient heat dissipation, ensuring reliable performance even during extended use. Designed for 19" rack mounting, the ZM 2124 is housed in a rugged black metal chassis that makes it both durable and aesthetically fitting for professional installations.
