CLOUD POWER AMPLIFIERS

Cloud amplifiers have been designed for sound reinforcement application within retail, leisure, commercial, hospitality or industrial sectors, giving the user access to multiple channels of amplification within a single rackmount unit.

CA2250

CA2250 is a Class-D amplifier that offers two channels of output into low impedance (4 or 8ohm systems), or 70/100V line systems. Each output of the CA2250 gives a maximum of 250W, and it is capable of analogue audio input via balanced/unbalanced 3-pin plug-in screw-terminal connectors, or Dante audio network input when the optional CDI-CA2 Dante board is retrofit.

When using the amplifier as part of a 70/100V line system, the maximum output of odd and even channels can be shared. This means, on the larger amplifiers like CA4250, CA6160, and CA8125, all of the even channels can together produce a maximum of 500W, and the odd channels can do the same. This is particularly useful when installing into a venue where multiple rooms with 70/100V line have differing numbers of speakers.

CA2250 has energy efficient properties including channel mute function that operates when no input signal has been detected for 15 minutes. The amplifier immediately ‘wakes up’ the channel or group when an input signal is detected. If no input signal is detected for 25 minutes, the automatic power down (APD) feature moves the channel or group into a low-power standby mode to consume less than 2.5W when all channels are switched. The user can alternatively use the remote standby/wake up function which uses external contact closure to operate.

The front facing panel features vents for forced-air cooling, along with LEDs to signify signal, peak, protection, and powered. The number of LEDs depends on the number of channels on the amplifier – in the case of CA2250 there are two of each LED. A power button allows the on/off switching of the amplifier. The rear facing panel again houses vents for cooling, mains IEC connection, and input connection via 3-pole, 3.5mm-pitch plug-in screw-terminal connectors. There is also a 2-pin connector for remote power down functionality when using external closure switching, connector for speaker output channels one and two, and a host of dip switches to switch channel Hi-Z/Lo-Z output, 4ohm/70V or 8ohm/100V, input routing, APD (auto power down) on/off, and channels one/two high pass filter – which is set at 65Hz.

Dante option cards

CDI-CA2, CDI-CA4, and CDI-CA8 are optional Dante network cards for CA series amplifiers. These retrofit option cards allow the amplifier to be directly fed from a Dante audio network. Any card will retrofit any CA series amplifier however it will be limited by the maximum number of channels in the given amplifier. The cards support 16/24/32bit PCM sample sizes, whilst also supporting 44.1/48/88.2/96kHz sample rates. The inputs can be controlled by Dante Controller and Dante Domain Manger software.
