WARNING: SHOCK HAZARD - DO NOT OPEN the unit may be degraded. The product conforms to the following European electrical AVIS: RISQUE DE CHOQUE ÉLECTRIQUE - NE PAS OUVRIR safety standard: BS EN 60065:2012 CX263 Installation and User Guide v1.1...
Disconnect the power cable from the unit before removing the top panel and do not make any internal adjustments with the unit switched on. Only reassemble the unit using bolts/screws identical to the original parts. CX263 Installation and User Guide v1.1...
What’s in the box OVERVIEW Unpack the CX263 and its accessories with care. It is always a Introduction good idea to store all packaging (if practical), in case you ever need to return the unit to your Cloud dealer for any reason.
POWER – Green LED, confirms power is applied to the unit. Rack mounting ears – the unit may be rack-mounted in a standard 19” equipment rack. It requires 1U of rack height. See “Hardware Considerations” on page 9. CX263 Installation and User Guide v1.1...
11. SERIAL INTERFACE CARD – optional CDI-S200 card with 9-pin Dsub connector. A blanking panel is fitted when the card is not installed. 12. MUSIC MUTE – Emergency control input for muting music source. See “Music Mute” on page 11. 13. IEC mains input 14. Mains fuse CX263 Installation and User Guide v1.1...
Suitable audio transformers, which should have a ratio of 1:1, are readily available from major audio component suppliers. The CX263 Zone Mixer is built in a 1U-high 19” rack mount The transformer(s) should be mounted as close to the Zone enclosure.
MIC 2 input (see “Mic-over-Music priority” on page Music Control 14 for full details.) Like many other Cloud products, the CX263 allows remote control of music level and source selection in each zone. Zone Outputs Cloud remote control plates from the RL-1 Series (music...
(typically the Fire System). The alarm output must be volt-free; if no such output is available, an intermediate relay or other isolation device must be installed between the alarm output and the Music Mute input. CX263 Installation and User Guide v1.1...
Gain & level To avoid dramatic changes in volume when switching between sources, the CX263’s music inputs are provided with preset gain trim controls ([2] on “Description of rear panel” on page 8). These vary the input sensitivity from -17.8 dBu to +6 dBu (approx.
To achieve a “flat” response for either microphone input, set Paging Access Control the controls for that input to 0 dB (the ‘12 o’clock’ position). On the CX263, MIC1 input may be used for paging purposes. Paging microphones from the Cloud PM Series (and also High-pass filter the older CDPM Series) are fully compatible;...
Microphone installed. The CX263 is fitted with HF and LF EQ adjustments 2. When the priority circuit is triggered, signals at MIC 2 input ([6] on “Description of rear panel”...
CDI-S200 Serial Interface Card The CDI-S200 is an optional RS-232C interface card designed specifically for use with the CX263. It can be retrofitted to the Zone Mixer at any time. It carries a 9-pin Dsub connector, which replaces the blanking plate adjacent to the mains connector on the rear panel.
Note that there is an internal 4k7 “pull-up” resistor between pin 2 and the internal +12 V rail. If pin 2 is left “floating”, this pull-up will result in full attenuation. The output impedance of the control voltage source should be low enough to overcome the effect of this resistor. CX263 Installation and User Guide v1.1...
To install equalisation modules, first remove the top cover from the CX263 (6 screws). The modules plug into the four empty, white 12-pin connectors in the centre of the main PCB. (Note that as Zone 1 is stereo it has two connectors.) The connectors on the main PCB have two notches on one side only;...
Music sources and levels could be set from the front panel of the mixer itself if preferred. Paging to any zone is achieved using a paging mic (such as the Cloud PM4) connected to Mic 1 input; this would typically be located somewhere other than within any one of the zones.
PCB jumper location and settings The CX263 has various internal jumpers, the setting of which may require alteration during installation. The table below lists each switch and jumper and its purpose, together with the factory default setting. JUMPER NAME EFFECT...
(see “Music Sources” on page 9). EMC considerations The Cloud CX263 fully conforms to the relevant electromagnetic compatibility (EMC) standards and is technically well behaved; you should experience no operational problems and under normal circumstances, no special precautions need to be taken.
