Amplifier:
• 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 70/100 V-line systems
directly
• Nominal power ratings: 2 x 500 W (CV2500), 4 x 250 W
(CV4250), and 8 x 125 W (CV8125)
• 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
• Per-channel, front panel LEDs for signal presence, peak level,
protection activity and power status
• Balanced line level inputs
• 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
70/100 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
DSP functions:
• On-board, per-channel DSP section providing extensive routing,
filtering, EQ and limiting for all channels including the auxiliary
outputs
• 1.5 s delay pool, freely assignable across all channels and aux
outputs
• Simple DSP configuration via on-board web server; any device
with a compatible web browser and an Ethernet connection
can be used to perform setup
• Built-in DSP crossover configurations allow amplifiers to be
easily used with 2-way speakers
• Crossover configurations allow derived LF sub output
• DSP-implemented 5-band parametric speaker EQ section
• Optional EQ presets for OEM speakers (under development)
• Password-protected multi-user security system
• Optional web monitor card performs load impedance tests and
reports out-of-tolerance results via a web interface or SNMP
