MANUAL DE USUARIO – LDA ZES-22
1 TECHNICAL DESCRIPTION
LDA ZES-22 is n udio DSP m trix b sed on the COBRANET Audio over Ethernet
st nd rd.
ZES-22 h s 4 ch nnels of udio input nd 4 ch nnels of udio output being these
configured by softw re s ch nnel input or output. It m y h ve up to four ch nnels of input
or output so be ble to send the udio over Ethernet using the COBRANET. St nd rd.
2 FUNCTIONING DESCRIPTION
ZES-22 llows both, the injection nd extr ction of n log udio ch nnel in network of
Ethernet COBRANET.
COBRANET llows up to 65536 “bundles” (where ´bundle´ is p ck ge with up to 8
ch nnels of digit l udio). A ZES-22 c n get up to 4 input ch nnels nd 4 output ch nnels
within the COBRANET network. These ch nnels c n be connected to ny of the n log
ch nnels using the intern l rr y. Also, it h s digit l system integr ted with the sign ls
(DSP) being ble to m ke sign l g in djustments, equ liz tion, filtering, limit tions, etc.
