Clearly better sound

Architect’s and Engineer’s Specication

The mixer shall be available in two versions, with four or eight electronically

balanced mono outputs (zones) on rear panel multipin connectors respectively.

Unless otherwise stated, all specications which follow shall apply to both

versions, with the two versions differing only in those facilities specic to the

outputs.

The mixers shall be equipped with six unbalanced stereo music inputs on rear

panel phono sockets (RCA jacks) and three electronically balanced microphone

inputs (plug-in screw terminal connectors). One of the microphone inputs shall

be congured specically to operate with paging microphones.

The music input to each zone and the music level in the zone shall be

adjustable by front panel controls. Each zone shall also have its own front panel

microphone level controls, one per microphone input. The level control for the

paging microphone input shall be of the preset type and recessed behind the

panel. It shall be possible to control the level of the music source independently

of the microphone levels in each channel.

Each music input shall have a rear panel input gain trim control with a range of

20 dB. Two-band equalisation adjustment shall be provided on the rear panel for

the music signal in each zone. Two-band equalisation adjustment shall also be

available for each microphone input; phantom power shall be available at any or

all microphone inputs when selected by internal jumpers.

A control input shall be provided to activate the paging microphone input by

external contact closure, and route its signal to any or all zones, replacing the

music signal while the contacts are closed. It shall also be possible to congure

the mixer to perform the following functions: i) detection of a signal on either

non-paging microphone input will automatically reduce the music level by 30 dB,

ii) detection of a signal on the paging microphone input will automatically route

the signal to all zones, iii) one line input will automatically override all others in

all zones, even if unselected.

Optional remote control panels shall be available to permit control of i) music

level in any zone; ii) music source selection and music level in any mixer channel;

it shall be possible to retrot these to the mixer at any time. The remote control

panels shall connect via a rear panel multipin connector. It shall be possible to

disable either the front panel music level or the music level and music source

selection controls by moving internal jumpers. An external control input shall

be provided to allow muting of the music source by a re alarm or other

external emergency system via isolated, ‘volt-free’ contacts, and this input shall

be congurable to respond to either a short or open external circuit. Front

panel LED indication of the muting action shall be provided.

Each zone output shall be provided with an additional balanced input on a

multipin connector; this input shall feed only its own zone. An optional input

plate shall be available to allow the connection of external microphone and

line level audio sources at a remote location, and this plate shall connect to

the mixer via the multipin connector, which also shall supply DC power and all

necessary control interface connections. The remote input plate shall allow the

connection of one microphone and one stereo line level input, with individual

level controls for each input, and sum the inputs. Controls shall also be provided

for music source selection and music level in the zone to which it is connected.

It shall be possible to enable the mixer’s music ducking facility from the plate.

The mixer shall accept internal plug-in equaliser cards to permit use with

compatible loudspeakers. It shall be possible to t these in any or all of the

zone outputs.

The mixer shall be built in a 3U steel chassis for mounting in a standard 19” rack.

The mixer will be tted with a front-panel power switch with LED indication.

Two mains supply variants shall be available: 230 V or 115 V. Mains supply shall be

connected via a detachable IEC cable.

The mixers shall be the Cloud Z4MK3 (four output zones) and the Cloud Z8MK3

(eight output zones); the optional remote control panels shall be the Cloud RL-

1series (music level only) and the Cloud RSL-6 series (music level and source

selection). The optional remote input plate shall be the Cloud LM-2.
