Funktion‑One XO4 DSP – 4 Input / 8 Output Audio Management Processor
The XO4 is a high-performance digital audio processor tailored for Funktion-One systems, manufactured to precise audio engineering standards. It offers four balanced inputs and eight balanced outputs with full matrix routing, built-in DSP, and network control compatibility.
Audio Processing & Performance
- Four balanced input channels matched with eight balanced outputs
- Native 96 kHz DSP sampling for ultra-wide bandwidth (extending beyond 30 kHz)
- Low-noise, high-resolution converters with very low distortion (< 0.02% at typical operating levels)
- High dynamic range and precision crossover alignment
Input & Output Capabilities
- Fully flexible input/output matrix: route any input to any combination of outputs
- Input DSP features: graphic and parametric EQ, delay, gain control, phase adjustment
- Output DSP features: crossovers (up to 48 dB/octave), parametric filters, delay, polarity, mute/gain control
- Delay resolution down to microseconds for precision timing alignment
Control & Networking
- Compatible with XTA AudioCore control software (via RS-485 or network with XO4A variant)
- Allows remote realtime configuration of EQ, routing, limiters, delay, and presets
- Manage up to 32 units remotely when using networked versions, allowing scalable system control
- Front panel display and low-profile controls provide local editing and navigation
Protection & Reliability
- Per-channel limiting options and global look-ahead protection for speaker safety
- Secure password provisioning and scene memory with preset recall options
- Internal clock for scheduled event recall (XO4A variant offers enhanced control communication)
