L-ACOUSTICS - LA-AES3 card for amplifier LA8 (New)

LA - AES3 card has a stereo AES / EBU and AES / EBU recovery to connect the LA4 and LA8 to any digital mixing console or any digital audio distribution system network input port , maintaining fully the signal in the digital domain.

Main Features :

1 AES / EBU input to specification AES3 (AES / EBU ) and IEC 60958 Type II (S / PDIF) , protected against electrostatic discharge

Automatic selection and instant analog inputs in case of failure of the AES / EBU input , with time constant propagation

Converter sampling frequency of high quality (Sample Rate Converter or SRC) accepts digital audio signals sampled Fs = 44.1 kHz to 192 kHz

Digital adjustable input gain - 12.0 dB to + 12.0 dB in 0.1 dB

1 port AES / EBU active with relay emergency recovery, protected against electrostatic discharge

Maximum cable length : up to 300 m ( with certified and dedicated to the transportation of the AES / EBU cables Fs = 48 kHz )

1 USB port ( reserved for future applications).

Automatic selection of analog inputs in case of failure of the AES / EBU input :

Switching conditions : Clock absence, loss of lock , invalid signal ( valid bit ), CRC error , error bipolar encoding, offset data
