Cloud Electronics CX261 Single Zone Mixer

The Cloud CX261 is a 1U rack-mounting stereo audio mixer intended for multi-purpose areas where simple control of high-quality background music needs to be combined with a flexible range of paging options.

The CX261 mixes any one of six stereo line inputs with one or two microphone inputs. Separate front panel controls for music source selection, music level and mic levels are provided. Either music level only, or music source and level may be controlled remotely if wished using standard Cloud RL Series or RSL Series remote control plates. In addition to the main 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 at line level.

LINE 1 input may be switched (on the rear panel) to an alternative front-panel 3.5 mm jack socket, to permit convenient connection of an MP3 player, laptop or similar portable audio source. A front panel LED confirms its selection. This input is provided with an independent front panel gain control and LED signal level indication.

The CX261 is fully compatible with the Cloud PM Series of paging microphones. The mixer may also be configured to operate with third-party paging systems: either mic input may be enabled via a simple short-to-ground access connection. This may be bypassed if wished, in which case the mic inputs are always active. 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 (Automatic Voice-Over) may be selected by internal jumper, and may be triggered either by the access connector or automatically by a mic signal (VOX mode). Additionally, MIC 1 may be set to have priority over MIC 2. Phantom power is available at either mic input (set by internal jumper). Bi-color LEDs indicating signal level are fitted to the rear panel to aid mic gain adjustment.

LINE 6 input may be set to have priority over any other selected music input to facilitate connection of a jukebox, digital sound store or similar device. One of three release times (up to 12 seconds) may be selected by internal jumper, to unobtrusively restore the original music source.

EQ cards to suit a range of popular installation loudspeakers from various manufacturers may be fitted to either or both channels of the main output. In common with most Cloud products, a Music Mute Input is provided, which may permit compliance with local Fire Authority regulations; the microphone inputs remain active when the Music Mute is applied.
