NXAMP USER CONTROLS
System Selection Allows control across all NEXO range
System Setup Within selected range, allows cabinets to be set for:
passive or active;
wideband or cross-over;
cross-over points;
omni or directional modes.
Protections (factory defined) Peak limiters fitted for both selected speaker and amplifier;
Acceleration protection preventing membrane stress
Displacement protection preventing over-excursion
Temperature protection preventing voice-coil damage
Inter-channel regulation
Delay Up to 150m (330ft) in 10cm (4”) steps
Input Patching Allows any of the inputs to be routed to any output
Output Gain Global and individual channel gain +/-6dB in 0.5dB steps
Volume Control Global and individual channel gain –inf to 0dB in 16 variable steps
Save / Recall Stores up to 40 user setups; “On-the-Fly” recalls
Array EQ LF or HF shelving filters to compensate for arrays quantity dependent behaviour
Security Mode Password protected for Read-Only or Remote-Only modes
