Digital Audio Channels Per Unit: 16 at 20-bit, 14 at 24-bit
Notes:
1. All specifications are typical for any channel(s).
2. All specifications are for AC line of 120 Volts rms.
3. All measurements are made via a CobraNet / AES signal path with
20-bit audio data transmit width.
4. All Cab16o measurements are made using 600 Ohm balanced loads
at 24 dBu full scale unless otherwise stated.
5. All Cab16i measurements are made using a 40 Ohm source imped-
ance at 24 dBu sensitivity unless otherwise stated.
6. All measurements are made with gain/attenuation set for unity
unless otherwise stated
7. Audio specifications for the CAB 16i are measured in the digital
domain after the signal has been transmitted through an Ethernet
switch and converted to AES format.
8. Audio specifications for the CAB 16o are measured in the analog
domain. The test signal is generated digitally in AES format and
transmitted to the CAB 16o through an Ethernet switch.
