Dynamic range to amplifier output

Analog input, better than 113dBA typical

AES / DanteTM input, better than 114dBA typical

Gain (with all DSP level controls set to 0dB)

32dB

Frequency response, 4 Ohm load

Less than 7Hz to greater than 30kHz, -2.5dB points

Total harmonic distortion, THD

Less than 0.05% typical, 1kHz signal, AES17 filter, 4 Ohm load

Inter-channel crosstalk, worst case combination

Better than -85dBr at 1kHz and -75dBr at 10kHz

Maximum analog input level

+20dBu

Analog input sensitivity range for full output

0dBu to +20dBu, continuously adjustable

Analog input and link

Input 20k Ohm, electronically balanced, link directly connected to analog input

Analog ground scheme

AES48 standard compliant

AES3 input

Transformer isolated with unique active cable equalisation for extended range

AES3 link

Active AES3 signal regeneration. Automatic direct bypass to the AES3 input ensuring

the audio signal will still flow even when the amplifier is powered down

AES3 supported sampling rates

24kHz to 192kHz (auto locking)

Digital Signal Processing

Resolution

40 bit, proprietary algorithms

Sample rate

96kHz throughout

Physical inputs to DSP drive modules

4x analog, 2x AES & 4x DanteTM inputs can be routed to four DSP drive modules

Drive module input processing

Input signal routing, delay, gain, high pass filter, polarity, mute

EQ: 2x low shelf, 6x parametric, and high FIR shelving filter

Drive module output processing

Source, delay, gain, polarity, mute, high pass and low pass crossover filters, VX limiters

EQ: low shelf, 8x parametric / all pass, and high shelf filters

Preset management

10 snapshots for device wide setup, 50 presets for loudspeaker settings

Presets can be recalled to sets of outputs or individual outputs as required

Unique high performance processing

Overlays

Twelve additional independent overlays of EQ, Delay and Gain

Flexible grouping for effective control of many amplifier channels in large systems

Class leading VX limiters

See the ‘speaker protection systems’ section

Hardman crossover filters
