Page 4: Safety Notes
Schematic Diagram Installation The Cloud Z4 and Z8 venue mixers are suitable for mounting in a standard 19” equipment rack and occupy 3 units of rack space. The units are 160mm deep but a depth of 235mm should be allowed to clear the connectors. Avoid positioning the units in close proximity to magnetic fields or equipment operating at a high temperature. -
Page 5: Sensitivity & Gain Control
& Z8 : Installation and User Guide Music Inputs - Sensitivity & Gain Control All six line inputs have a pre-set gain control on the rear panel, adjacent to the respective input sockets. The input sensitivity can be varied from –12dBu (195mV) to +8dBu (2.0V). The pre-set gain controls should be set so that all the input signals operate at the same level within the mixer so that the change in level when switching sources is minimal. -
Page 6: Paging Mic
Once the input gain control has been set the paging mic level of each zone can be optimised by adjusting the front panel mounted pre-set level controls. The Cloud CPM-4 & CPM-8 zone paging microphones are available as an optional accessory, both microphones feature zone selection switches allowing paging to all four or eight zones in any combination;... -

Page 8: Microphone Priority
& Z8 : Installation and User Guide Microphone Priority Fully automatic, voice operated priority is provided. When any microphone is used, the music signals will attenuate by approximately 30dB; after the announcement, the music signals will restore smoothly to their former level. Priority over Mic 1 & Mic 2 is provided for the paging mic only;... -
Page 9: Microphone Priority Over Facility Input
In certain circumstances, there may be a requirement to mute the music signals via a fire alarm control panel in an alarm condition. The Cloud Venue Mixer provides a facility to mute the music signals by connecting the two pole music mute connector to a pair of relay contacts that are controlled by the fire alarm control panel. -
Page 10: Controlling The Music Functions Using External Dc Control
Controlling the music functions using external DC control The Cloud Z4 and Z8 can be used as part of an automated sound system by controlling the music level and music source by an external 0-10V DC voltage. The 3-pole connector normally used to terminate the RSL-6 control plate can be used to feed two separate control voltages into the mixer on a zone by zone basis. -
