Page 3: Safety Notes
The Cloud 36/50 is a versatile, multi-source two zone mono mixer with integrated power amplifiers. The 36/50 has one 50 watt power amplifier for each zone plus an additional 50 watt ‘utility’ output. The unit has applications where one microphone and six line level music signals are required to feed up to three separate areas. -
Page 4: Installation
The 36/50 is 300mm deep but a depth of 375mm should be allowed to clear connectors. -

±10dB at 10kHz and the music bass control operates with a range of ±10dB at 50Hz. Priority The Cloud 36/50 has a facility to allow fully automatic priority to a JukeBox or Spot Announce Player on both zones. Internal priority jumpers J12 (Zone1) and J13 (Zone2) can be repositioned to the ‘ON’... -

• Use a microphone that requires phantom power. Microphone Access Inputs The 36/50 has microphone access contacts to facilitate the connection of a paging microphone. Internal jumpers J2 (Zone 1), J3 (Zone 2) and J4 (Utility) should be removed if a paging microphone is to be used. -
Page 7: Microphone Gain Control
36/50: Installation and Operation Manual Multiple CPM paging microphones can be connected to a 36/50 when wired as the following diagram shows, each microphone will require an external power supply (CPM-PSU): - Microphone Gain Control A pre-set gain control is provided adjacent to the XLR input connector. The gain can be adjusted from 0dB to 60dB and this wide range of gain allows direct connection of high output devices such as radio microphones without the need for additional attenuation. -
Page 8: Speaker Output Details
A three-channel line transformer module – the CXL-3120 is available as an accessory. This gives the 36/50 up to three 100V or 70V, 40 watt outputs. This module is designed to fit inside the mixer chassis and may be configured for 70 or 100V operation by means of wire links on the PCB. -
Page 9: Remote Music Mute - Fire Alarm Interface
This is usually a relay mounted close to the 36/50, which is powered by the fire alarm control panel. The relay should close during an alarm condition (the installation of this relay is normally undertaken by the fire alarm installation company). -
Page 10: Controlling Two Or More Zones With One Rsl-6
Controlling the music functions using external DC control. The 36/50 can be used as part of an automated sound system by controlling the music level and music source by an external 0-10V DC voltage. The 3-pole connector normally used to terminate the RSL-6 can be used to feed two separate control voltages into the unit. -
Page 11: Solving Problems
36/50: Installation and Operation Manual Level Control A maximum gain reduction of 60dB can be achieved with a control voltage of +10V; the rate of attenuation is approximately 165mV per dB. A control voltage of zero realises unity gain (full volume), however, with no external connection to pin 2, an internal 4k7 resistor connected to the +15V power will ‘pull up’... -
