The Bose PANARAY system digital controller utilizes digital signal processing (DSP) architecture to provide smooth, accurate spectral response for any Bose professional loudspeaker product requiring active equalization (EQ) or additional processing. Any Bose professional loudspeaker EQ can be accessed by simply selecting the appropriate preset and configuration. No programming is required. The controller has two balanced XLR analog inputs and four balanced XLR outputs. It can be configured to run two mono Bose EQ presets or a single stereo Bose EQ preset (including preset crossover settings). Mains voltage: 100 to 240VAC, 50Hz to 60Hz (auto switching). Power consumption: < 15WIn addition to providing Bose speaker EQ presets, the controller also has the following easy-to-use programmable features:Four independent signal delays (200 ms per output) which can be used for decentralized or distributed speaker alignment and for creating custom bass arrays.Four independent output limiters that can be set to protect speakers from unpredictable spikes in program material.A programmable signal router which allows each output to select full-range and high- or low-pass combinations of input signals.Sample Rate: 44.1kHzConnectors: (2) XLR balancedImpedance balanced: 21k?Input level: Maximum: +18dBu / Minimum: 0dBuSensitivity: @9dB headroom: -12dBu to +9dBuA to D conversion: 24 bit, 128 x oversampling bitstreamDynamic range: 95dB typ, 20Hz - 20kHzTHD: ...
