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)
