The Cloud CX261 is a 1U rack-mounting, stereo, audio mixer intended for use in commercial audio systems where simple control of background music needs to be combined with a flexible range of paging options. It will mix one of six unbalanced stereo line inputs with up to two balanced microphone inputs.
Line level inputs are via RCA (phono) sockets, each with individual gain control. Line 1 is switchable between RCA and MP3. During MP3 operation an alternate front panel 3.5mm socket is used for the connection of mobile phones, laptops and other mobile devices. This input is provided with an independent gain control and LED signal level indication. Line 6 can be set for priority over other music inputs via internal jumper. This can be particularly useful in retail environments and visitor centres where it may be desirable to use a digital sound store to play call-to-action announcements. One of three user-selectable release times of up to 12 seconds can be set to unobtrusively restore the original music source.
Two balanced microphone inputs are made via terminal-block connectors, each with independent gain control. Mic 1 priority over mic 2 can be set via internal jumper. A short-to-ground access connector or VOX-triggered voice-over-music priority is available on both mic inputs. A switchable isolating transformer configures Mic 1 input for direct connection to a telephone system, enabling paging messages to originate from an extension. Mic-over-music priority may be selected by internal jumper, and may be triggered either by the access connector or automatically by a mic signal (VOX mode). 12V phantom power available to each microphone input. The CX261 is compatible with Cloud PM Series paging microphones. Rotary knobs are used to select line/MP3 music source, music level and mic levels.
Either music level only, or music source and level may be controlled remotely using Cloud RL Series or RSL Series remote control plates.
In addition to the main L/R stereo output, there is a transformer isolated mono auxiliary output which is suitable for providing a MOH (Music on Hold) output to a telephone system. All outputs are balanced line level via terminal block connectors. A Music Mute Input is provided (N/O or N/C), which may permit compliance with local Fire Authority regulations. The microphone inputs remain active when the Music Mute is applied.
