All control functions will be self-contained and not require any external computers

or software.The Mixer/Zoner shall be built in a steel chassis for mounting

in a standard 19” rack enclosure.

The front panel shall incude:power switch,backlit LCD display,rotary encoder with

“press”function and software-assignable push-buttons for control functions.One of

the buttons shall control the Mixer/Zoner’s menu system.Five further buttons shall

select submenus, and another button shall activate a set of menu options which

require the entry of a password.The password shall be re-definable by the User.

The front panel will have various LEDs indicating: external paging access, remote

line input selection,remote mic input selection and emergency Music Mute activity.

The Mixer/Zoner shall have 8 stereo line channels,4 microphone inputs and

a paging mic input. Line inputs shall be on RCA jacks,one shall also be available

as a balanced input on a Euroblock connector,four shall also have RJ45 sockets

providing balanced inputs for the connection of optional balanced or unbalanced

stereo external connection plates.The microphone inputs shall be balanced

on RJ45 sockets for the connection of optional external connection plates.

The line Inputs shall each have level trim adjustment via software.

The Zone outputs shall be balanced, on Euroblock connectors.Two shall be stereo,

the remainder mono. It shall be possible to adjust the following parameters for

each Zone output:Level, Maximum and Minimum Levels; EQ (3-bands). It shall

be possible to route any microphone or line input to any Zone output without

restriction, and to adjust each Zone output level independently.It also shall

be possible to make one or more line Inputs unavailable to any Zone without

restriction. It shall also be possible to define up to 4 Groups of Zones;

enabling/disabling Groups shall be possible without entering the password.

The Mixer/Zoner shall interface directly with a Cloud CDPM network and/or

any other paging microphone.The (non-CDPM) Paging Mic input shall be on

a Euroblock connector;routing this to any/all Zones will be by contact closure

at a separate Euroblock connector. Both Paging Mic inputs shall have rear panel

gain controls;HF and LF EQ controls shall also be provided,effective on both inputs.

There shall be a rear panel paging level adjustment for each Zone.The music signal

in a Zone shall reduce in volume when that Zone is being paged, and the Hold

Time, ReleaseTime and Music Attenuation shall all be adjustable.It shall also be

possible to trigger music level reduction by Zone Selection or Paging Mic signal

presence. It shall be possible to assign per-Zone Priority status to any line or

microphone input, such that a Priority signal above a fixed threshold overrides the

current Input selection in each Zone for as long as the Priority signal remains above

the threshold. In connection with this, the following parameters shall be adjustable:

HoldTime,ReleaseTime; Music Attenuation (Mic Priority only).

There shall be a Music Mute Input, a control signal at which mutes the Music

in all Zones. Muting control shall be configurable on either external contact closure

(NO) or short-circuit removal (NC).It shall also be possible to assign any one line

or microphone Input to remain unmuted during Music Mute operation for

Emergency system interface. It shall be possible to assign alphanumeric names to all

Inputs,Zones and Groups;these will still apply after any hardware reset operation.

It shall be possible to save all current settings and reload these settings when

power is applied.Alternative power-up options shall be to load the original factory

settings or those in force at power-down,even if they were not specifically saved.

The Mixer/Zoner shall incude an RS232 serial port permitting remote control

of all unit functions and settings.An optional remote control panel shall be available

for the Mixer/Zoner. The panel shall be provded with IN and OUT sockets

to permit series interconnection of up to 100 panels in any wiring configuration.

It shall be possible to configure a panel to provide the following control functions

for its assigned Zone:for immediate access - Line Input Select and Music Level;

with password entry – Zone EQ (3 bands).

It shall be possible to retro-fit certainType II Bose equaliser cards to any or all

Zone outputs.Compatible cards shall include Bose Product Codes 035467/70-

3/5/6 and 038533 as a minimum.The Mixer/Zoner shall be the Cloud DCM-1;

the remote control panel the Cloud CDR-1; the remote input plates the Cloud

LE-1 (unbalanced line), Cloud BE-1 (balanced line) and Cloud ME-1 (microphone).
