46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED 5.2 Setup And Installation Guide Music Control - Local or Remote The music source and music level control functions can be controlled from either the front panel, or a remote control plate located up to 100m from the 46/50. There are two remote control plates available for the 46/50 the RSL-6 and the RL-1.
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED Setup And Installation Guide 5.3 Music Equalisation 5.4 Line 6 Priority over Zone 1 Each zone has separate treble and bass controls for the music signals only, allowing an installer to tailor the response of the music signals to suit the acoustics and speakers of each individual zone.
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED 6 Setup And Installation Guide Microphone Inputs Two microphone inputs are provided each having electronically balanced, transformer-less circuitry configured for optimum low noise performance. The input impedance is greater than 2kW and suitable for microphones in the 200W to 600W range. Inputs are via 3-pin plug in screw terminal type connectors (Phoenix type) located on the rear panel.
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED 6.1 Setup And Installation Guide Paging Microphone & Access Contacts The Cloud PM4 four zone paging microphone is an accessory for the Cloud 46/50; it features zone selection switches which allow paging to all four zones in any combination and a 'call all' button that is used for convenient announcements to all zones. In addition to this the PM4 has a built in chime. The PM4 connects to the 46/50 via its analogue interface.

See the “PM4/8/12/16 Installation and User Guide”, page 27, “Systems with multiple paging microphones” for more details.
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED 6.6 Setup And Installation Guide Microphone Level Controls Each zone has separate front panel mounted level controls for Mic 1 and Mic 2. The level controls allow the user to adjust the microphone signals to a suitable level in any zone; rotating any Mic level control fully anti-clockwise effectively turns the microphone off.
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED 7 Setup And Installation Guide Output Details 7.1 Speaker Outputs 7.2 Auxiliary Outputs Each speaker output uses a 2-pole plug-in screw terminal (Phoenix type) located on the rear panel; these connectors can accommodate flexible leads up to 2.5mm². It is good practice to distance output wiring from input wiring at all times and use twisted pair cable for the speaker wiring, ensuring that it remains twisted right up until termination.
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED 9 Setup And Installation Guide Zone 1 Facility Input Facility Input Pin Configuration Zone 1 has a facility input; this 9 pin sub D connector provides direct access to the zone and is primarily used to connect one of the dedicated active remote input modules such as the DM-1 or LM-1. An active module can extend the facilities of the 46/50 by providing local zone access and control remotely. (See section 11 for more details on active modules).
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED 11 Setup And Installation Guide Active Remote Modules The Cloud DM-1 & LM-1 are the same physical size as a double UK electrical socket (BS4662 & BS1363 type) and can be mounted in the recessed back box provided or be surfaced mounted in a standard 35mm deep housing. The modules should be wired back to the facility input of the 46/50 using a single multi-core screened cable.
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED 11.2 Setup And Installation Guide DM-1 Dual Microphone Input Module The Cloud DM-1 is a remotely located active module with two balanced microphone inputs via 3 pin female XLR connectors. Each input has a level control and tamperproof treble and bass equalisation controls. A 'music ducking' switch provides facility input priority over the main system music if required. Modules can be linked when wired in a 'daisy chain' format (see section 11.
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED Setup And Installation Guide 11.4 LM-1 Mic/line plus remote control of music signals. The Cloud LM-1 is a remotely located active module with a balanced microphone input, a line level music input and music source select & level controls (rather like a built in RSL-6). A microphone priority switch provides the option to reduce the level of the music signal when the mic is used. Use 9 core screened cable to wire the LM-1 to the 46/50.
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED 13 Setup And Installation Guide Active Speaker Equalisation Modules Each output channel has the facility to connect a plug-in, speaker equaliser module. See the table below for details of the connector for each output and the respective bypass jumper. Installation: 1. 2. 3. 4. 5. 6. Switch off the mains supply and remove the 46/50’s power lead. Remove the unit’s top panel Remove bypass jumper (see table below for jumper map).
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED 14 Setup And Installation Guide 100V or 70V Line Operation A four-channel line transformer module the CXL-4160 is available as an accessory. This gives the 46/50 up to four 100V or 70V, 40 watt outputs. This module is designed to fit inside the 46/50 chassis and may be configured for 70 or 100V operation by means of wire links on the PCB. Unless specified otherwise, the module is pre-configured for 100V output.
46/50 Integrated Mixer Amplifier Setup And Installation Guide CLOUD ELECTRONICS LIMITED 16 DC Control of Music Functions The 46/50 can be used as part of an automated sound system by controlling the music level and music source with a pair of external 0-10V DC voltages. The 3-pole connectors that are normally used to terminate RSL-6 or RL-1 remote control plates can be used to feed two separate control voltages into the 46/50 on a zone-by-zone basis.
46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED 17 Setup And Installation Guide Solving problems 17.1 Ground loops (aka Earth loops) Despite your best efforts, if the completed sound system 'hums' you probably have a 'ground loop'; the offending signal source can be found by setting the volume control to minimum then disconnecting the input leads (both left & right channels) on each line input until the 'hum' disappears.

46/50 Integrated Mixer Amplifier CLOUD ELECTRONICS LIMITED Setup And Installation Guide Safety Considerations and Information The unit must be earthed. Ensure that the mains power supply provides an effective earth connection using a three-wire termination. When the mains switch is in the off 'O' position the live and neutral conductors of the mains transformer are disconnected. CAUTION - Installation Do not expose the unit to water or moisture. Do not expose the unit to naked flames.
