VOCIA AMPLIFIER 8600/8600c (VA-8600/VA-8600c)
The VA-8600 and VA-8600c are digital networked multi-channel ampliers. Both the VA-8600 and the VA-8600c are CobraNet® enabled
and feature eight channels of modular amplication, and DSP with optional channel-to-channel or device-to-device failover. The VA-8600c
is designed to be used specically with EN 54-16 certied systems, with the AM-600c card. It can support up to eight amplier cards that
are individually software congurable from 100–600 Watts for up to 2400 Watts of power per chassis, with software-selectable 70V, 100V,
and low-impedance outputs per card. The on-board DSP provides comprehensive xed-chain digital signal processing within the device,
including volume control, ducking, equalization, compressor/limiter, speaker crossover, delay, and output gain. Emergency messages for
life-safety compliant systems are stored in non-volatile memory within the VA-8600 and VA-8600c. Intuitive software provides audio system
design via PC computer. Two RJ45 connectors on the rear panel of the VA-8600 and VA-8600c provide redundant connectivity to control
data and audio over a single Ethernet cable.

Channel Indicators Chassis Indicators
Figure 2. System Indicators
Channel Indicators
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 AM-600 or AM-600c 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 AM-600 or AM-600c 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 in 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 conguration
where failover is enabled.

Page 6
VA-8600/VA-8600c FRONT PANEL
Signal is a tri-color LED that indicates audio signal presence on the channel. Green indicates that the audio signal level is between
-50 dBFS and -3 dBFS, yellow indicates a signal level between -3 dBFS and 0 dBFS, and red indicates clipping.
Chassis Indicators
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 VA-8600 or VA-8600c
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 VA-8600 or VA-8600c 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 VA-8600 and VA-8600c unit. If the LED is dark, there is
no conguration in the unit. A green LED indicates that the unit is congured and a yellow LED indicates that the unit is congured and in
standby. Standby only occurs when a unit has been designated as a redundant device in a conguration where failover is enabled. A red
LED indicates a conguration load failure.
Status is a tri-color LED that indicates the health of the VA-8600 and VA-8600c hardware. A green LED indicates that 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 that the unit experienced a problem during the power-on self test.
Power is a green LED that illuminates when power is applied to the unit.

Device ID Switches
The rotary ID switches are located on the back of the VA-8600 and VA-8600c and give the unit a unique Device ID. The switches are in
hexadecimal format. All VA-8600 and VA-8600c units must have a unique Device ID to function properly within a Vocia Paging World (i.e.,
it is not possible to have two VA-8600 and VA-8600c units with the same Device ID of hex 07). To assign a Device ID of hex 07, turn the
LSB switch to 7 and leave the MSB switch on 0. To create an ID of hex B7, turn the LSB switch to 7 and turn the MSB switch to B. Device
ID switches should be set using a 0.1 inch (2.5mm) to 0.12 inch (3.0mm) flat blade screwdriver. More information on setting IDs and
the hexadecimal numbering scheme used in Vocia can be found in the Vocia Help File.
Power Entrance
The Power Entrance provides for connection of the appropriate power cord (included with unit). A switch selects the operating voltage
for the power supply, 110–120V or 220–240V at 50/60 Hz.
NM-1
NM-1 is the Network Module that is included with VA-8600 and VA-8600c. This module provides connectivity for control and audio via the
dual CobraNet interface and logic ports for the device failover functionality. The RJ45 connector labeled "Ethernet" is not used at this time.
Reset Button
Reset button, when held down for 5 seconds, performs a chassis restart. The Status indicator will ash yellow during restart and will turn
solid green once the process is complete.
Logic I/O
The Logic I/O connector on the NM-1 facilitates redundant device failover only. It is not a general-purpose contact closure interface.
See the Amplier-to-Amplier Failover section below.

Page 8
VA-8600/VA-8600c REAR PANEL
Network Connection
The VA8600 and VA-8600c are CobraNet devices. All CobraNet routing and bundle assignments are processed by the Vocia devices
locally. Vocia makes dynamic use of available bundles in CobraNet. Vocia devices are currently not interoperable with nonVocia devices. A 10/100Base-T Ethernet switch (not repeater hub) is required when networking multiple units. CobraNet utilizes
standard CAT5, CAT5e, CAT6, or CAT7 cabling, which has a specied maximum length of 328 feet (100 meters). Additional Ethernet switches, or switches which provide fiber-optic interface, can be used to extend the physical distance between units within a
network. Please note that CobraNet limits network extensions to seven hops (one-way transmissions) within a network.
The primary and secondary CobraNet ports are provided to facilitate connection redundancy. Each connector provides two LEDs that
indicate Ethernet link and network activity (see table below).

AM-600/AM-600c
AM-600 or AM-600c is the Amplier Module card. A VA-8600 or VA-8600c chassis can be populated with up to eight AM-600 or AM-600c
cards. The AM600c reports a fault if it detects a short to ground on a speaker line, where this short would compromise the capability of the
amplier to deliver emergency messages
Output
Use the yellow plug-in barrier strip connectors to connect loudspeaker level outputs. If stranded speaker wire is used, be sure to incorporate
all strands into the connector, as stray strands can short to the adjacent terminal or chassis. Do not leave excessive bare wire outside
the terminals, as this can lead to shorts.
Please note: The VA-8600 and VA-8600c are powerful ampliers
and can damage loudspeakers. Please treat the VA-8600
and VA-8600c outputs as you would AC mains power outlets.
Always check the loudspeaker’s continuous and peak power
capabilities and match the amplier settings accordingly.

Amplier-to-Amplier Failover
Vocia supports one-to-one automatic amplier failover in case of fault. Failover is triggered by one of the following conditions:
Chassis fault•
Channel fault•
Loss of power•
Loss of CobraNet link•
Loss of Logic I/O•
Only faults (e.g., heat sink fault and channel failure fault) trigger the failover mechanism. Warnings indicate abnormal system conditions that
do not immediately impair audio and do not trigger the failover mechanism.
The redundant amplier must have the same conguration as the primary amplier (i.e., amplier module count, watts per module, load
conguration). A wire failover link cable must be connected between the primary and the redundant amplier as shown below. Connect ground
to ground and logic 4 of the primary amplier to logic 3 of the redundant amplier; connect logic 3 of the primary amplier to logic 4 of the
redundant amplier. Leave logic 1 and 2 disconnected. The redundant amplier can be wired in parallel to the existing speaker line or it can
be connected to a redundant speaker line (see gure below). Relays isolate the output terminals on the secondary VA-8600 or VA-8600c
unit. Relays are normally open. When a conguration is received, relays close on the primary VA-8600 or VA-8600c and remain open on
the redundant VA-8600 or VA-8600c. On failover, the relay position is switched.
Primary VA-8600/8600c
Redundant VA-8600/8600c
After replacing the faulty amplier, a power cycle is required to recover from failover. The primary device will resume control after the fail
condition is cleared and the unit is re-powered.

Channel-to-Channel Failover
In addition to entire amplier failover, Vocia supports channel-to-channel failover, which is triggered by one of the following conditions:
Heat Sink fault•
Short Circuit fault•
Channel Failure fault•
The wire failover link cable is not required when wiring channel-to-channel failover.
The redundant channel can be wired in parallel to the existing speaker line (shown above) or connected to a redundant speaker line.
The primary amplier module will resume control after the fault condition is cleared and the unit is re-powered.
