VOCIA AMPLIFIERS VA-2060, VA-2060e, VA-4030, VA-4030e
The VA-2060, VA-2060e, VA-4030 and VA-4030e are digital networked multi-channel audio ampliers designed for use in Vocia systems.
All models are CobraNet® enabled and feature either two or four channels of amplication, with on-board DSP. Channel-to-channel or
device-to-device failover may be user congured. Each amplier channel has user selectable support for 4 or 8Ω operation or Constant
Voltage operation of 25, 70 or 100 Volts. The on-board DSP provides comprehensive xed-chain digital signal processing within the device,
including volume control, ducking, equalization, compressor/limiting, speaker crossover, delay and output gain. Locally stored audio messages are retained in non-volatile memory within the amplier. Intuitive software provides audio system design via PC computer. Two RJ45
connectors on the rear panel of the amplier provide redundant connectivity to control data and audio over a single Ethernet cable. The
VA-2060e and VA-4030e models have the ability to be powered via dual 24V connections in addition to the AC mains power supply, as well
as balanced mic/line inputs to be used as a local background input source for the output channel associated with the Input.

The Vocia software provides the interface for conguring and programming the VA-4030(e) and VA-2060(e) ampliers. The information
supplied by this manual relates to hardware installation, physical connections and device and channel failover concerns. For more details
on software setup, please consult the Vocia Software Help File.

VOCIA AMPLIFIERS VA-2060, VA-2060e, VA-4030, VA-4030e FRONT PANEL
System Indicators
The LED indicators on the front panel of the amplier provide information and operational status of the amplier and its associated output
and input channels. LED layout and features vary between amplier models. LEDs are grouped to show chassis and amplier channel
status indication. Please see the Front Panel View section for details on the different congurations between the various amplier models.
Chassis Indicators
Amplier Chassis Indicators
These indicators relate to the entire amplier unit (chassis):
AC power is a green LED indicator. This will illuminate when a AC Mains supply is applied to the unit.
DC Power (VA-2060e and VA-4030e models only) is a green LED indicator. This illuminates when an auxiliary DC supply is applied to the
unit via either or both 24V Auxiliary power inputs.
Refer to the caution in the Rear Panel Auxiliary Power section.
Amp Fault is a yellow LED that illuminates when a chassis fault has occurred. There are two types of chassis faults that can be reported,
depending on the severity of the problem. Flashing yellow indicates a Warning, which means that some aspect of the amplier chassis is
not performing within normal specication. Audio may still be passing, but if the condition causing the Warning is not corrected, chassis
failure may occur. Solid yellow indicates a fault, which means that some aspect of the amplier chassis has failed and audio may no longer
be passing through the device. Use Vocia software to determine the specic type of chassis warning or fault that has occurred.
Activity is a tri-color LED that illuminates to show the conguration status of the device. If the LED is dark, the chassis has failed to
boot or there is some other kind of fault. A solid green LED indicates that the unit is congured. A ashing yellow LED indicates the unit is
active but not congured. A solid yellow LED indicates that the unit is congured and in standby. Standby only occurs when a unit has
been designated as a redundant device when Device Failover is enabled.
Status is a tri-color LED that indicates the health of the amplier hardware. A green LED indicates the unit powered up normally. A ashing
yellow LED is shown briey during the power-up self test and should turn solid green upon successful start. A red LED indicates the unit
experienced a problem during the power-up self test.

Channel Indicators
Amp Channel Indicators
These indicators relate to each amplier channel:
Amp Fault is a yellow LED that illuminates when a channel fault has occurred. Two types of channel faults can be reported depending on
the severity of the problem. Flashing yellow indicates a Warning, which means that some aspect of the amplier module is not performing
within normal specication. Audio may still be passing, but if the condition causing the Warning is not corrected, channel failure may occur.
Solid yellow indicates a fault, which means that some aspect of the amplier module has failed and audio is no longer passing on that
channel. Use Vocia software to determine the specic type of channel warning or fault that has occurred.
Activity is a two-color LED that illuminates green when that channel is congured and actively passing audio and yellow when that channel is
congured and in standby. Standby only occurs when a channel has been designated as redundant channel in a failover conguration.
Signal is a tri-color LED that indicates audio signal presence on the amplier channel. Green indicates the audio signal level is between
-36 dBFS and -6 dBFS, yellow indicates a signal level between -6dBFS and -2 dBFS and red indicates clipping (above -2dBFS).
Analog Input (VA-2060e and VA-4030e models only) is a tri-color LED that indicates audio signal presence on the amplier analog Input
channel. Green indicates the audio signal level is between -48 dBFS and -18 dBFS, yellow indicates a signal level between -18 dBFS and
-2 dBFS and red indicates clipping (above -2dBFS).
