Cloud Electronics, UK introduces its new range of energy efficient, class-leading amplifiers with the introduction of its new CVA-Series digital multi-channel digital amplifiers.

Flexible Output

All models in the CV-Digital series offer a total power output capability of 1KW, shared across the amplifier channels. This flexible approach allows a single, multi-channel amplifier, to drive loudspeaker systems differing in load size, in different areas of a building or venue, whilst optimising overall power output capability. (100v only)

Ethernet / DSP

A full suite of user configurable DSP functionality is on-board the CVA-Digital series, which includes input routing, multi-band parametric room and speaker optimisation EQ, output level control and limiting, and 1.5s of assignable delay. Amplifiers can be easily set up for multi-channel or parallel channel operation and bi-amping, with full control of crossover parameters.

Auxiliary Outputs

Providing the same DSP power as the normal amplifier channels, the auxiliary outputs can be configured as traditional slave outputs, or used as independent signal processing and routing channels.

Analogue and Digital Control

The CVA-Digital series amplifiers are compatible with standard Cloud RL Series remote level control plates. DSP parameters are accessible via RS-232 and Ethernet, for interfacing to third-party control systems. A 3-way GPIO port can be configured for external master mute and fault condition signalisation

Specifications

• Advanced design of 2, 4, and 8-channel Class D power amplifiers
• Standard “out-of-the-box” Cloud amplifier functionality: requires no computer configuration or internal access for basic operation
• Transformerless output stage drives 70 V/100 V line systems directly
• Nominal power rating: 4 x 250 W (CV4250)
• Thermal protection, overcurrent limiting and DC offset protection
• Switch-on delay for speaker protection during power-up
• On 4, and 8 channel models, power sharing allows odd and even channel groups to deliver a maximum of 500 W each (on 70/100V only)
• Per-channel, front panel LEDs for signal presence, peak level, protection activity and power status
• Balanced line level inputs
• Optional Digital Interface Bus
• Per-channel output level controls
• Rear panel input routing switches configure amplifier for manual selection of multichannel, stereo or mono operation
• Rear panel switches select 70 V line or 100 V line output levels
• Per-channel high-pass filter (65 Hz default frequency: adjustable in software) to protect against transformer saturation in 100 V/70 V line systems
• Balanced, line level auxiliary outputs with full channel functionality, configurable and controllable via software
• Independent Automatic Power Down on odd and even channel groups; minimises power consumption in absence of an input signal
• <3 W power consumption with all channels quiescent
• RS-232C serial port for remote control of all amplifier functions, including DSP configuration
• Compatible with standard Cloud RL Series remote level control plates (per-channel)
• Remote Power Down control input
• 3-way GPIO port for master mute function or fault reporting
• Variable speed forced-air cooling
• 2U 19” rackmounting units
