WHEATNET-IP 88cb CONSOLE BLADE
I/O Connections
Two female XLR connectors are microphone preamplier inputs. Recessed rear
panel phantom power switches and gain trims can be independently congured, and one
RJ‑45 connector connects the preamp outputs to any one of the Analog Input RJ‑45’s.
Eight RJ‑45 connectors are for audio inputs. The rst four RJ‑45 jacks are analog
inputs which can be set up as four stereo, eight mono, or any combination of stereo
and mono. The last four RJ‑45 jacks are AES digital inputs.
The Console BLADE also has eight RJ‑45 connectors for audio outputs. The rst
four RJ‑45 jacks are set up as analog stereo outputs, and the last four RJ‑45 jacks are
set up as AES digital outputs. The “Console” template, by default, has a signal map
that automatically cross connects the surface’s Program, Headphone, Cue, and Studio
signals to the designated outputs. The Digital outputs follow the Analog outputs and
cannot be independently connected to different audio sources.
An RJ‑45 and four 1/4" jacks are provided for headphone and cue outputs.
Four XLR male connectors are provided for control room and studio outputs.
The BLADE also has two more RJ‑45 connectors to provide 12 logic ports, which
can be individually designated during setup as inputs or outputs. These ports are where
you wire the various external switches, indicators, and control functions you need in
your facility.
There are two RJ‑45 jacks for Ethernet. One is for 1 Gigabit Ethernet – connect
this one to your network. The 100 Megabit Ethernet port is not used – do not connect
anything to this port.
Consult the wiring diagram on page 4‑8 for detailed information.
The unit has a standard IEC power connector. The BLADE has an internal power
supply that will accept 100‑240 volts 50/60 hertz AC power.
Inputs
The WheatNet-IP
88cb 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
microphone preampliers is fed from one of the two female XLR connectors. When
using the internal microphone preampliers, 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 four additional RJ‑45 connectors.
