Cloud USA Z8MK4 Overview

The Z8MK4 3 U Rackmountable Audio Mixer from Cloud USA is a multi-zone mixer that combines simple control of background music with versatile microphone paging for up to eight separate areas. It is suitable for use in many types of premises, including pubs, bars, clubs, shops, offices, hotels, and more. It has six stereo line inputs, four balanced and two unbalanced and three microphone inputs, one of which is configured specifically for use with paging mics. The mixer has eight separate mono zone outputs. The front panel provides separate controls for music source selection, music level, and two mic levels in each zone. The EQ cards are suitable for various models of installed sound loudspeakers that may be fitted to any or all outputs.

The audio mixer is compatible with Cloud PM Series paging microphones via the Cloud Digital Paging Interface, which requires a single Cat5 cable for connection. The interface allows a second mixer to be cascaded, permitting up to 16 zones to be addressed. The paging mic input can alternatively be configured to suit most OEM paging systems, zone selection for paging being via short-to-ground access connections. Each zone may be independently configured for music ducking, triggered either by the access port or VOX control. The ducking feature has selectable release times. The paging mic has priority over the other mic inputs (Mic 1 and Mic 2). Paging mic level to each zone is set with a recessed front panel preset control. When Mic 1 and/or Mic 2 are in use, music ducking can also be enabled on a per-zone basis. Additionally, Line input 6 may be set to have priority over any other selected music source in any zone, to facilitate connection of a digital sound store, jukebox, emergency message system or similar source.

The Z8MK4 audio mixer is provided with a multi-purpose Facility Port. The purpose of the port is to connect the LM-2 remote input plates (sold separately) which allows mic and/or line level sources located in the zone to be routed to the zone’s audio system. The Facility Port can also be used as a general purpose, balanced, line level, auxiliary zone input.
