–
The digital signal processor (DSP) Matrix Mixer is the heart of the PLENA matrix system. When combined with the Call Station (PLM‑8CS) and the Wall Control Panel (PLM‑WCP) making announcements and controlling individual zones is easy. The multi channel DSP amplifiers (PLM‑4Px2x) can be connected via STP type CAT‑5 (Amp Link) or via phoenix terminal connectors. The internal audio matrix can control announcements (via the call station), mix four mic./line inputs, and select any of the three background music sources and deliver these to a total of eight independent zone outputs. There is also a logic input for emergency override that will take priority over all other inputs. Control of the DSP features is via Ethernet connection and use of the product GUI of Windows or iPad.
–PLM-4P125 and PLM‑4P220 – Multi channel DSP Amplifiers:
With the exception of the power output, both Class‑D multi channel DSP Amplifiers are virtually identical in features. The amplifiers come with advanced DSP features which are accessed by the PC GUI. Both amplifiers feature the “Amp Link” CAT‑5 cable connection to connect easily to the PLM‑8M8 DSP Matrix Mixer. Loudspeaker outputs are for 100 V, 70 V, 8 Ohm and 4 Ohm operation. The amplifier channels can also be bridged together to make more powerful outputs. The amplifiers also feature an auto standby mode that significantly reduces the power consumption making the amplifiers more cost effective and environmentally friendly.
