P8136 Master unit


The multi-zone system is particularly suitable for large and small installations in which particularly reliable, versatile and practical equipment is required. The simplicity with which the various different units and the control bases can be connected to one another even when far away (CAT 5 connections)  makes sound-broadcasting inside complex buildings effective and inexpensive, using both centralised and/or local control units. Both the Master unit (P8136) and the Slave unit (P8236) enable management of up to six zones each. It is possible to activate/de-activate music for each zone using the front-panel switches provided for this purpose.  The Master and Slave units can be used for switching both line signals (one amplifier for each zone) and the power signals (output from the amplifier, 100 V line). In this latter case, it is possible to connect two amplifiers (one for music and the other for speech, two-channel system) or a single voice/music amplifier (single-channel system). To increase the power being managed, the units have provisions for connecting two amplifiers for speech (3 zones each) and two for music. Depending on the size and configuration of the audio system, it is possible to use the Master and/or Slave units separately or connecting them to one another. The maximum system configuration envisages the use of 6 Master control units connected to 30 Slave units (five for each Master), thus managing up to 216 voice/music broadcasting zones. Up to 16 PMB106-G and/or PMB112-G microphone consoles can be connected to each unit.

Unlike the Slave unit, on the P8136 there are four inputs for auxiliary sound sources with a selector switch and level control, two line inputs with automatic priority activation (VOX) and four RJ45 inputs for PMB106-G and/or PMB112-G call stations to be configured as Masters and able to control all the zones in the system. The P8136 has provisions for inserting an optional ACMG8136 card, needed for automatic and/or manual broadcasting of pre-recorded messages. ACIO8136 cards can also be connected to the same lines as the “local” or “master” microphone stations. These are expansion cards with one balanced line input and 6+6 programmable input/output contacts and they can be used to send pre-recorded messages and/or the incoming audio signal to the various different zones in the system.
