Hardware Interface Description
Audio Network Interface (ANI)
Front Panel
① Input Channels
Adds analog line- or aux-level signals to the digital network. When
associated to the APT, inputs are automatically routed to linked
microphone channels (Input A to channels 1-4; Input B to 5-8). Typical
applications include sending translated audio or a mix for personal
monitoring at the microphone headphone jack.
② Output Channels
Sends analog audio out from the digital audio network. When connected
to the MXW system, the outputs are automatically routed from the
associated MXWAPT.
③ Channel Select Button
Selects a channel and performs the following functions:

Mute/unmute a channel. Mute is indicated by
the⑥MuteLED.
④ Selected Channel LED
Illuminates when a channel is selected.
⑤ Signal Strength LED (sig/clip)
Indicates audio signal strength for each channel:
Green = Normal
Amber = Strong
Red = Clipping (to eliminate clipping, attenuate the signal level at the
audio source)
⑥ Mute LED
Illuminates red when the Channel Select button is held for 3 seconds,
muting the channel. A muted channel is still routed to the HEADPHONE
jack for monitoring or troubleshooting.
⑦ Input Level Select Buttons
Set the selected channel to line- or aux-level to match the input signal.
⑧ Output Level Select Buttons
Set the selected channel to an output level that matches the connecting
device:
line: +4 dBU
aux: −10dBV
mic: −30dBV
⑨ Output Gain Control
Use the up/down buttons to adjust the channel gain attenuation from 0
dB (no attenuation) to -24 dB.
⑩ Output Gain Setting
Displays the attenuation made from the Output Gain Control.
⑪ Level Meter
Displays a selected channel’s audio level in dBFS. It is good practice to
use -18 dBFS on the output meter as an approximation of 0 VU on an
analog meter.
⑫ Hardware Status LEDs
Illuminate to indicate the status of the hardware:
