CloudPower CP1504D

CloudPower 4-channel Class-D amplifier is built for easy remote control and monitoring using the IntelliCloud WebUI, reducing site visits.  It features fully integrated DSP and GlidePath architecture for ultra-low distortion, along with True Cone Excursion to extend speaker life. The ‘D’ models include 4×4 Dante integration, and it supports both low impedance and 70/100v speakers. Designed for networked or standalone setups, it also includes a high-visibility OLED display, ultra-quiet airflow management, and operates with high efficiency and low idle power in a slimline 1U chassis with a universal power supply and PFC.

ALF-MA15075D

The ALF-MA15075D is a compact digital mixing amplifier designed for low or high impedance applications. The mode selector switch allows it to deliver either two channels of 75 watts per channel into 4 or 8 Ω, or a single channel of 150 watts at 70 or 100 V. The use of a Class-D amplifier provides power efficiency and energy-saving. In addition to the amplified speaker output, a line level audio output allows the mixed audio signals to be sent to an additional amplifier or other audio system. Feature:
  •  Inputs: 2 x Dante audio, 1 x optical audio, Stereo balanced analog input, 2 x balanced microphone inputs
  • Outputs: 1 x balanced line level outputs, Stereo Low Impedance amp out, 1 x 70V/100V amplifier output
  • Selectable low or high-impedance operation.
  • 2 x 75 watts @ 4 or 8 Ω.
  • 1 x 150 watts @ 70 or 100 V.
  • Class-D amplifier design.
  • Automatic standby after a period of inactivity to minimize power consumption.
  • Rear panel input level controls for setting Microphones input gain.
  •  Low inrush current to prevent audible “thumps” when multiple amps are powered on simultaneously.
  • Balanced analog audio output for pass-through to an additional amplifier or audio system.
  • Basic integrated DSP functions including five-band Graphic equalizer.
  • GUI Webserver with TCP/IP control for remote control or third-party integration.
  • Trigger port for external mute/ unmute trigger.
  • Front panel signal status LEDs for power, panel button lock, audio source, mute, and real-time volume level.

Crest Audio – CKd 604

The CKd Power Amplifiers combine the legendary overbuilt power supply design made famous by the Crest Audio Pro 200™ with NexSys® networking functionality and an ultra-lightweight class D topology. The design centers around an ultra-high efficiency amplifier output circuit that reduces weight while increasing output power, reliability and thermal efficiency. The CKd Series offers four multi-channel models to meet the needs of demanding audio installations. The CKd 1208 and CKd 1204 provide 1,250 Watts per channel in eight and four channels, respectively, while the CKd 608 and CKd 604 provide 625 Watts per channel in eight and four channels. Each amplifier channel will operate to rated power in direct 70-volt, 100-volt, 8-ohm or 4-ohm modes, configurable per channel. CKd amplifiers are networkable through Crest Audio’s Nx Dante-8™ and Nx Cobranet-8 NexSys control modules and either Crest Audio NexSys 5 or Peavey® MediaMatrix® NWare™ software programs for advanced control and audio routing. The Nx Dante-8 and Nx Cobranet-8 modules fit into the rear bay of CKd Series power amps and support all NexSys functions, DSP functions and Dante digital audio I/O (via 1 Gigabit Ethernet connection) or Cobranet digital audio I/O (via 100baseT connection). A Control Voltage input is included on each channel to allow external gain control, while the Fault output on each channel allows the CKd power amps to be wired to other monitoring systems. In addition, users can conserve energy by disabling channels that are not in use. The CKd Series includes Crest Audio's exclusive ACL™ (Active Clip Limiting), which automatically reduces gain at the onset of clipping to prevent amplifier and load damage, and IGM™ (Instantaneous Gain Modulation), which monitors load current to protect against overloading.
