Ctrl. Interface
• REST control API over Ethernet.
• Control4 driver available.
• Trigger input and output, 12Vdc on, 0Vdc off.
Processor
• Analog Devices, internal processing sample rate 192 kHz, bit depth 64 bits.
• Bohmer Correction is a Loudspeaker In-room Energy-Time alignment that optimizes the loudspeaker
room acoustic transfer function in both frequency and predominantly time domain. Working with
revolutionary new algorithms it starts with a psychoacoustically based measurement method.
