Page 5: Safety Notes
General Description The Cloud 46/50 is a versatile, Four Zone 50W x 4 Integrated Mixer Amplifier. It has applications where up to two microphones and six line level music signals are required to feed four separate areas in any combination. -
Page 6: Schematic Diagram
PHANTOM POWER The Cloud 46/50 occupies two units of a standard 19" equipment rack. Sufficient ventilation should be provided particularly where it is required to deliver a high output power for long periods of time; the unit draws cool air through the front panel and exhausts through the rear panel. The 46/50 is 320mm deep but a depth of 400mm should be allowed to clear connectors. -

46/50 Integrated Mixer Amplifier Setup And Installation Guide CLOUD ELECTRONICS LIMITED 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. -
Page 13: Output Details
46/50 Integrated Mixer Amplifier Setup And Installation Guide CLOUD ELECTRONICS LIMITED Output Details Speaker 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. -

Page 19: 100V Or 70V Line Operation
46/50 Integrated Mixer Amplifier Setup And Installation Guide CLOUD ELECTRONICS LIMITED 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. -
Page 20: Dc Control Of Music Functions
46/50 Integrated Mixer Amplifier Setup And Installation Guide CLOUD ELECTRONICS LIMITED 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. -
