Damping factor (ref 8 ohms) >800 at amplifier output
Maximum analogue input level +20 dBu
Analogue input sensitivity range for full output 0 dBu to +20 dBu, continuously adjustable
Analogue input 20k ohm, electronically balanced
Analogue link Directly connected to the analogue input
Analogue ground scheme AES48 standard compliant
AES3 input Transformer isolated with active cable equalisation for extended range
AES3 link
Active signal regeneration with automatic direct bypass to the AES3 input if
the unit is unpowered
AES3 supported sampling rates 24 kHz to 192 kHz (auto locking)
Digital processing
Resolution 40 bit, using proprietary LMD (Linea-Micro-Detail) algorithms
Sample rate 96kHz throughout
Special functionality:
Class leading limiter suite (See the ‘speaker protection systems’ section )
Hardman crossover filters (Better out of band rejection than Linkwitz-Riley)
LIR crossover filters (Linear Phase without the compromises of FIR filters)
FIR Shelving EQ filters (For linear phase filtering)
Overlays (Twelve additional independent overlays of EQ, Delay and Gain)
