1 CLOUD MPA Seies Mixe-Amplifies Clealy bette soun 48.6 mm mm 3½ (U) MPA Seies - font panel view (MPA40 illustate) MPA Seies - ea panel view ( illustate) Geneal Desciption The Clou MPA Seies is intene to povie a complete auio solution fo Houses of Woship, etail outlets, hotels, license pemises an othe spaces whee music, announcements an/o flexible paging ae equie. It combines the functions of a fouchannel micophone mixe, full paging facilities, a six-input music souce selecto an a mono powe amplifie in a single U unit. The MPA ange consists of thee moels, which iffe only in the ate powe of the amplifie stage: 60 watts MPA10 10 watts MPA40 40 watts (all atings ae into 4 ohms) The MPA mixe-amplifies have six unbalance steeo line inputs fo music souces, an fou balance micophone inputs. Each micophone input has its own ea panel sensitivity contol an font panel gain contol, allowing multiple mics to be mixe togethe. Each line input has a ea panel sensitivity contol; the equie music souce is selecte by a font panel otay switch an the volume is also ajuste on the font panel. The selecte music souce is mixe with the summe mic signals befoe being fe to the powe amplifie stage. The MPA Seies is compatible with the Clou PM1 single-zone paging micophone, an may also be use fo one of the zones suppote by the Clou PM4/8/1/16 multizone paging micophones. Altenatively, Mic 1 input may be configue to suit most OEM paging systems; paging is activate by a shot-to-goun access connection, an Mic 1 may be configue to have automatic pioity ove the othe mic inputs to pevent announcement clashes. Mic inputs may be selecte to have automatic pioity ove the selecte music souce, an aitionally, one line input may be set to have pioity ove any othe selecte to facilitate connection of a igital soun stoe o simila evice. A pe-announcement chime may also be enable at installation. A ange of EQ cas to match the MPA Seies to vaious popula installe-auio louspeakes is available. A 100/70/5 V tansfome is fitte as stana, an the output stage ives high-impeance line louspeake istibution systems iectly. An intenal jumpe allows the tansfome to be isable, pemitting the amplifie to to be use to ive low-impeance louspeakes. Music level only, o music level an souce selection may be contolle emotely if wishe, using stana Clou emote contol plates. In common with most Clou poucts, a Music Mute Input is povie, which may pemit compliance with local Fie Authoity egulations; the micophone inputs emain active when the Music Mute is applie. All Clou poucts ae exclusively esigne in the UK. Evey Clou pouct is exhaustively teste fo electonic pefomance an sonic pefection in Sheffiel, Englan.

Any of the music souces can be selecte an the music level contolle fom the RSL emote contol plate at the back of the space. Depening on the size of the aea, any of the thee moels - (60 W), MPA10 (10 W) o MPA40 (40 W) - coul be use. The system is shown with multiple speakes being iven fom the high-voltage (100/70/5 V) output, though in a smalle space, fewe speakes being iven iectly fom the low-impeance output might be moe pactical.

Any one of five steeo music souces may be selecte in the aea by the RSL emote contol plate, which can also be use to set the volume. Input 6 has its pioity option set, an is connecte to the output of a igital soun stoe, which coul fom pat of a wie builing management system. This woul typically play time, pe-ecoe, non-emegency messages. The MPA40 s multiple mic inputs ae paticulaly useful in such an application, as seveal mics ae often neee simultaneously in eceptions, pesentations, an the like. The example shows thee aio mics which ae in aition to the paging micophone connecte at Mic 1 input. The MPA40 can be configue to give the paging mic pioity ove any music souce, an also othe micophones, if equie. In an emegency situation, all music inputs woul mute une contol of the fie system.

7 Clealy bette soun Achitect s an Enginee s Specification The mono mixe-amplifie shall be equippe with six unbalance steeo music inputs on phono sockets (RCA jacks) an fou balance micophone inputs on multipin connectos. The music input to be use shall be selectable by a 6-position font panel otay switch. The fou mic inputs shall be mixe to a mono signal an summe with a mono (L+R) sum of the selecte music input. Each mic input shall have its own font panel level contol. It shall be possible to contol the level of the music souce inepenently of the mic levels. Each music input an each mic input shall also have a ea panel gain contol. -ban equalisation ajustment shall be povie inepenently fo the selecte music souce an summe mic signals. A contol input shall be povie to activate one mic input (Mic 1) by extenal contact closue; it shall be possible to configue the mixe-amplifie such that this function is oveien an Mic 1 is always active. It shall be possible to configue the mixe-amplifie to pefom the following aitional functions: i) when activate by its contol input, Mic 1 will take pioity ove any othe mic input in use; ii) etection of a signal on any mic input will automatically euce the music level by 30, iii) one line input will automatically oveie all othes, even if unselecte. Optional emote contol panels shall be available to pemit contol of music level only o music level an input selection; it shall be possible to etofit these to the mixe-amplifie at any time. An extenal contol input shall be povie to allow muting of the music souce by a fie alam o othe extenal emegency system. The mixe-amplifie will inclue a chime geneato cicuit tiggee by a signal on Mic 1 input; it shall be possible to intenally isable/enable this function. The micophone mixe stage shall inclue a high-pass filte to emove backgoun LF noise below 100 (-3 ). A secon highpass filte shall be inclue to emove LF content below 65 (-3 ) fom the mixe music an mic signals to minimise tansfome satuation in 100/70/5 V-line systems; this filte shall be intenally by-passable. Two sepaate intenal fixe limite cicuits shall be fitte; these shall be locate at i) the output of the micophone mixe stage an ii) at the input of the powe amplifie stage. Opeation of eithe limite shall be inicate by a font panel LED. The mixeamplifie shall incopoate potection cicuity that isolates the output i) uing powe-up, ii) in the event of DC being etecte at the amplifie output, iii) if the intenal heatsink tempeatue excees 90 C (194 F). The mixe-amplifie shall be available in thee moels with iffeent output powes of 60 W, 10 W o 40 W, into a 4 ohm loa. The mixe-amplifie shall be capable of iving eithe low impeance (4 ohms o highe) loas, o 100 V, 70 V o 5 V line systems via an intenal tansfome fitte as stana. It shall not be possible to use both types of output simultaneously. The 100 V, 70 V an 5 V tansfome outputs shall be available on sepaate ea panel output teminals, shoue by a scew-attache safety cove. The mixe-amplifie shall accept intenal plug-in equalise cas to pemit use with compatible louspeakes fom vaious manufactues. The mixe-amplifie shall be built in a U steel chassis fo mounting in a stana 19 ack. Tempeatue-contolle foce-ai fan cooling with font-to-ea aiflow shall be employe. The amplifie will be fitte with a font-panel powe switch with LED inication. The mixe-amplifie shall be the Clou (60 W output), the Clou MPA10 (10 W output) o the Clou MPA40 (40 W output). The emote contol plates shall be the Clou RL-1 Seies (music level only) an the Clou RSL Seies (music level an souce selection). Clou Electonics Limite 140 Stanifoth Roa, Sheffiel, S9 3HF. Englan.
