VU-NET OPERATION
Vu-Net is Martin Audio's monitoring and control application. It may be used with the DD12,
either stand-alone or in conjunction with other Martin Audio network-ready products such as
MLA, MLA Compact, MLA Mini and PSX. Connection between a PC and the DD12 (or other
system components) may be made:
•
directly on a one-to-one basis via USB (note the maximum USB cable length is 5 m),
•
directly on a one-to-one basis via a Silex Ethernet-to-USB converter, or
•
by using a Merlin system processor as a PC-to-network hub. When a Merlin is in use,
interconnection between the various cabinets in the system is via the U-Net network
protocol.
Vu-Net is also used to upload DSP parameters to the DD12, and to perform system firmware
checks.
It is important to realise that once a set of DSP settings has been uploaded into the system, the
presence or absence of a U-Net network in no way affects normal audio operation; cabinets will
continue to pass audio with their last known configuration even without an operational U-Net
network. This applies also to power-cycling: the DD12 retains the last-used set of parameters
when powered down and reloads them when re-powered, whether they were a Preset or
a modified set of parameters loaded from Vu-Net.
DSP functions which can be controlled via Vu-Net include level, mute, polarity, input selection,
delay, high pass filter and 10 bands of parametric EQ. User Presets can be stored and recalled
via the rear panel switch after the network is disconnected.
For full details please see the Vu-Net User guide which is available from the Martin Audio
website.
