  • Auto-Mixer
  • Ambient Noise Compensation
  • Dynamics processing with auto-ducker
  • EQ & crossovers including FIR filters
  • Time alignment and tower delay
  • Scheduled noise-masking with Real-Time Clock
  • Swept AC load-analysis with baseline logging
  • FIR Filter capable, dynamics, gain, equalization, 2x4 or 4x4 matrix mixer, crossover, delay, metering, and signal generator functions for test and noise masking applications
  • Precision swept load impedance monitoring of each amplifier channel
  • Ethernet Control and monitoring of amplifier functions, with front panel COM activity LED
  • Serial data port for use with Ashly remote control devices, or optional RS- 232 converter for third party controllers (INA-1)
  • Use Protea™ Software to remotely disable all front panel controls, including the on/off switch, for a tamper-proof installation
  • Real-Time Clock with Event Scheduler
  • Instant Standby Mode 30% reduction in power consumption with on/off and Preset Recall, both via contact closure, software control, or event scheduler
  • Programmable power-on delay
  • Aux preamp outputs, and fault condition logic outputs
  • Optional Cobranet™ or Dante® and AES3 digital audio input with passthru
  • Rear panel DIP switches select low impedance (2, 4, and 8 Ohm), constant voltage (70V or 100V), high pass filter, limiter and input gain on each channel
  • Ashly Energy Management System (EMS) for increased efficiency) automatic <1Wsleep-mode (defeatable)
  • Switch mode power supply automatically detects 120V or 240V AC operation
  • Extensive protection circuitry
  • Continuously variable cooling fans
  • Front panel power switch and level controls (can be disabled for security)
  • Multiple internal power supplies provide increased channel separation and reliability
  • Remote DC level control on each input channel (2 RU models only)
  • Genuine Neutrik® connectors on 2 RU models for security, safety, and reliability
  • Safety / Compliance: cTUVus, CE, FCC, RoHS
