I/O Connections
All audio input and output, control, Ethernet, and power supply connections are made
via various connectors mounted on the VP-8
iP
’s rear panel.
Six XLR connectors are provided for analog and digital audio input and output con-
nections.
Four BNC connectors are provided for SCA in and TX (transmitter) out connections.
An RJ-45 connector is provided for Ethernet connection, which can be used to con-
nect a Windows
®
PC running the VP-8
iP
GUI.
The two DB-9 connectors provide eight GPI inputs for the first eight presets and
four GPO outputs.
The pinout drawings on pages 1-15 through 1-18 summarize all wiring connections.
Audio Inputs
The VP-8
iP
accepts three types of audio input sources:
• Balanced analog line level left/right audio;
• Digital AES3 compliant left/right audio with sample rates between 32kHz and 96kHz;
• Optional WheatNet-IP via 100BaseT Ethernet connection to a WheatNet-IP audio
network.
Input audio can be applied to all inputs simultaneously.
Automatic audio failover from analog to digital or vice versa is supported.
Automatic failover from AES3 or WheatNet-IP to analog is instantaneous and based
on invalid or missing bits in the AES3 or WheatNet-IP stream, or after 30 seconds of
“silence” (level below -48dBFS).
Automatic failover from analog to AES3 is based on silence sense responding to
audio on both channels being below -48dBFS for more than 30 seconds.
Failover from AES3 to WheatNet-IP (or vice versa) is not available.
