The WheatNet-IP 88cb and 88cbe console BLADEs can be fed from three different
types of inputs: microphone, analog line level, and AES-3 digital.
When processing mic level (-50dBu nominal) inputs, the input to the internal micro-
phone preamplifiers is fed from one of the two female XLR connectors. When using the
internal microphone preamplifiers, a jumper must be connected from the MIC OUTS
RJ-45 to a selected Analog input (1-4). The mic preamp has digitally controlled gain,
up to a maximum of 70dB, and displays remarkably high performance and accuracy.
Phantom power is available via recessed rear panel switches.
Four RJ-45 connectors can be used for analog line level inputs. The line level analog
audio inputs are +4dBu balanced. The analog line inputs exhibit a bridging impedance
and can handle signals up to +20dBu.
To handle digital line level sources there are also four RJ-45 connectors.
The digital inputs of the WheatNet-IP 88cb and 88cbe (inputs 5-8) will accommo -
date digital inputs having a wide range of sample rates. These inputs will be sample rate
converted to the system’s chosen sample rate of 44.1kHz or 48kHz, which is set via the
WheatNet-IP Navigator GUI. The GUI also allows you to select input 8 of the digital
BLADE, or of any BLADE that has a digital input as input 8, to be a primary external
reference, and a digital input 8 from a different BLADE to be a secondary external ref-
erence. Please note that the sample rate of a digital input 8 should be the same, either
44.1kHz or 48kHz, as the system’s chosen sample rate.
AES sources are by design stereo; if the BLADE is not set to be stereo the appropri-
ate Left or Right signal within the AES stream will be applied to the signal path.
