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 amplifiers designed for use in Vocia systems. All models are CobraNet® enabled and feature either two or four channels of amplification, with on-board DSP. Channel-to-channel or device-to-device failover may be user configured. Each amplifier channel has user-selectable support for 4 or 8Ω operation or Constant Voltage operation of 25, 70 or 100 Volts. The onboard DSP provides comprehensive fixed-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 amplifier. Intuitive software provides audio system design via PC computer. Two RJ45 connectors on the rear panel of the amplifier provide redundant connectivity to control data and audio over a single Ethernet cable. The VA-2060e and VA-4030e models can 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.

VOCIA AMPLIFIERS VA-2060, VA-2060e, VA-4030, VA-4030e FRONT PANEL

System Indicators

The LED indicators on the front panel of the amplifier provide information and the operational status of the amplifier and its associated output and input channels. LED layout and features vary between amplifier models. LEDs are grouped to show chassis and amplifier channel status indication. Please see the Front Panel View section for details on the different configurations between the various amplifier models.

Amplifier Chassis Indicators

These indicators relate to the entire amplifier unit (chassis):
AC power is a green LED indicator. This will illuminate when an 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. Two types of chassis faults can be reported, depending on the severity of the problem. Flashing yellow indicates a Warning, which means that some aspect of the amplifier chassis is not performing within normal specification. 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 amplifier chassis has failed and audio may no longer be passing through the device. Use Vocia software to determine the specific type of chassis warning or fault that has occurred.

Activity is a tri-color LED that illuminates to show the configuration 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 configured. A flashing yellow LED indicates the unit is active but not configured. A solid yellow LED indicates that the unit is configured 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 amplifier hardware. A green LED indicates the unit is powered up normally. A flashing yellow LED is shown briefly 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.

Amp Channel Indicators

These indicators relate to each amplifier 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 amplifier module is not performing within normal specifications. 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 amplifier module has failed and audio is no longer passing on that channel. Use Vocia software to determine the specific type of channel warning or fault that has occurred.
Activity is a two-color LED that illuminates green when that channel is configured and actively passing audio and yellow when that channel is configured and in standby. Standby only occurs when a channel has been designated as the redundant channel in a failover configuration.
The signal is a tri-color LED that indicates an audio signal presence on the amplifier channel. Green indicates the audio signal level is between -36 dBFS and -6 dBFS, yellow indicates a signal level between -6 dBFS and -2 dBFS, and red indicates clipping (above -2 dBFS).

Analog Input (VA-2060e and VA-4030e models only) is a tri-color LED that indicates audio signal presence on the amplifier 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 -2 dBFS).

Conventions

All numbered audio, relay, and power connectors on the rear panel of the amplifier are configured with the lowest output or input on the right of the connector as viewed from the rear of the unit.

AC Power Socket
Provides for connection of the appropriate power cord. Each amplifier uses a switch-mode power supply that has an operating voltage of 100-240V at 50/60 Hz.

Auxiliary Power : Only available with VA-2060e and VA-4030e amplifiers.

Caution : Due to potential energy hazards, connections to the Auxiliary Power 24V DC inputs must be made by a qualified electrician or other qualified person as required to conform with all local codes.

This connection allows dual 24V DC power inputs to be used. Dual 24V DC supply capability allows the amplifier to meet standards that call for redundant power supplies. The DC supply must be wired into both power supply inputs, either from redundant supplies or from a single supply wired in parallel to the two inputs. If 24V is not supplied to both inputs, a loss-of-supply fault will be reported. If a VA-4030e or VA-2060e amplifier is required to operate without a 24V supply, the Auxiliary supply fault monitoring must be disabled in Vocia software. A loss of supply fault is indicated via the Vocia software and by a blinking yellow Amp Fault indicator on the front panel of the affected device. The power supplies used for the amplifier must meet the voltage range and power requirements detailed in the specifications table below. Local standards, norms or codes may require the use of certified power supplies and may require observance of minimum on-battery running times both for standby and maximum power conditions. Note that dual redundant power supplies must each independently meet the total power requirements of the amplifier.
The pluggable terminal blocks provided will accommodate wire sizes from 12-18 AWG. External over-current protection must be provided, according to the current carrying capacity of the connecting wires, and in no case greater than 30 Amps. Do not ground or connect to chassis either the positive or negative Auxiliary Power connections. The Auxiliary power must be floating with respect to the ground.

Network Connections

The amplifier is a CobraNet device. A Primary and Secondary CobraNet connection is provided for this. All CobraNet routing and bundle assignments are processed by the Vocia devices locally. Vocia makes dynamic use of available bundles in CobraNet. A 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 specified maximum length of 328 feet (100 meters). Additional Ethernet switches, or switches that provide the 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 CobraNet network connection is configured with the primary connector on the left and the secondary (redundant) connector on the right. The primary and secondary CobraNet ports are provided to facilitate connection redundancy. Each connector provides two LEDs that indicate the Ethernet link and network activity.

Table 1. CobraNet LED indication

Device ID switches

The rotary ID switches are located on the back of the amplifier and give the unit a unique Device ID. The switches are in hexadecimal format. All Vocia units of the same type must have a unique Device ID to function properly within a Vocia Paging World (for instance, it is not possible to have two Vocia devices of the same type with the same Device ID of hex 07). Note that VA-4030 and VA-4030e units represent one device type, while VA-2060 and VA- 2060e units represent another device type.
As an example, to assign a Device ID of hex 07, leave the MSB switch on 0 and turn the LSB switch to 7. To create an ID of hex B7, turn the MSB switch to B and turn the LSB switch to 7. 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 can be found in the Vocia Software Help File.

Analog Audio Inputs with Phantom Power Option

For the VA-2060e and VA-4030e, each amplifier channel has analog inputs that allow a locally balanced microphone or line-level background source to be delivered to the amplifier channel associated with that input. Two such inputs are available on the VA-2060e amplifier and four on the VA-4030e. Input sensitivity and 48V phantom power on/off state may be determined in the Vocia software. Because a local input may only be delivered to the channel associated with that input, if a local background source is required on two or more chan-nels the source must be wired in parallel to each of the inputs. An exception is that if two or more channels of an amplifier are configured in software as a group or multi-way, the lowest local input channel number will be presented to all channels. For instance, if a VA-4030 is deployed with channels 2, 3 and 4 configured as a group or 3-way multi-way, local input 2 will be presented to outputs 2, 3 and 4.

Page Active Relay

Page Active Relays (PAR) are available on all amplifiers. Via the Page Active Relay connectors, one Form C (single pole, changeover) relay is presented per channel for the VA-4030 and VA-4030e. Similarly, two such relays per channel are presented for the VA-2060 and VA-2060e (relays operate in tandem). Each PAR connector is a six-way 3.5mm pluggable screw terminal block. The PAR connections are labeled as follows:

• C : Relay Common
• NC : Normally Closed
• NO : Normally Open

Page Active Relay: VA-4030e and VA-2060e

Amplifier Output Connections

CAUTION : All speaker wiring connections and output load selection should be made by qualified personnel and with the amplifier power removed. The 100V output requires Class 3 wiring. Please refer to a qualified electrician or other qualified person according to local codes.

Transformer Load Selection

The required amplifier output load is configured via the use of a recessed indented selector above the amplifier speaker output connectors. The switch is designed to be operated with a flat blade screwdriver (blade width 0.1”- 0.25”/ 2.5mm – 6.4mm). Selection can be made between 4 or 8Ω for Low Impedance connections and 25V, 70V or 100V for Constant Voltage loads. By default, the amplifier factory default setting is 8Ω. Do not operate the amplifier with no speaker load. If an amplifier channel is unused (i.e., has no load) do not configure the channel in Vocia software to pass audio.

Speaker Connection

To minimize power loss, use a speaker cable of appropriate gauge for the load impedance. For long speaker cables, to minimize high-frequency loss, choose a low-capacitance cable. Use the supplied 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. Use of the supplied cable restraints is required to secure the cable in the connector. To facilitate parallel wiring, each connector allows for the connection of two loads to each amplifier channel. Two four-way connectors are available on the VA-2060 and VA-2060e amplifier and four connectors are available on the VA-4030 and VA-4030e amplifier.

Rated Load Table : The total output load connected to any channel must not be less than the rated impedance load for that channel, as detailed below. Operating the amplifier in excessive overload may cause power supply safety limiting.

Output Fault Detection

The Amplifier monitors (supervises) for faults on speaker connections using a combination of multiple out-of-band (inaudible) high-frequency tones for end- of-line detection, and DC current for ground fault detection. For end-of-line detection, one or more (up to 15 maximum) ELD-1 units must be connected to the end/s of the speaker line. End-of-line and ground fault detection may be individually enabled/disabled in the Vocia software. To ensure the correct operation of fault detection it is necessary to follow these guidelines:

• When an ELD-1 is being used in a Vocia system it is important that the Amplifier Output Setting in the software matches the Hard-ware Output setting selected on the physical amplifier (8Ω, 4Ω, 25V, 70V or 100V). See the Software Help file for more information.

• Recorded audio messages or audio content with continuous or swept tonal components (e.g. alert tones) and any content with significant high-frequency harmonic content should be band-limited (>24dB/octave) at 15 kHz during recording. Note that program content that is distorted due to poor recording techniques may contain excessive high-frequency harmonics.

• Signal level adjustments within a Vocia system should be set so as to minimize clipping. Severely clipped signals may also affect the out-of-band fault detection tones.
  The use of speaker cables that inherently attenuate high frequencies is not supported (e.g. screened cables). Speaker cables must maintain frequency response to the end of line of less than -3dB @ 20kHz at with respect to 1kHz.

• Speaker cables longer than 500 feet may prevent the correct operation of ELD and Ground Fault monitoring capabilities. An advantage of Vocia is that amplifiers may be easily distributed close to speakers, thereby minimizing long runs of expensive and potentially lossy speaker cable.

• Highly capacitive speaker lines or loads may prevent the correct operation of the ELD detection system.

• Legacy-monitored speaker circuits that use capacitors and resistors or similar methods must have all legacy monitoring circuitry removed for the correct operation of the ELD detection system.

The amplifiers use DC current to detect whether there is an erroneous ground connection placed on either or both speaker wires. The detection circuit will declare a fault for a resistance to ground of 50kΩ or less. To prevent false ground fault readings, the DC resistance to ground of speaker circuits must be 100kΩ or higher (either speaker wire to ground).

• For EN54-16 compliance, one or more ELD units must be fitted. End-of-line detection and Ground Fault Detection must be enabled in the Vocia software.

Failover Modes

The Vocia amplifiers support a device-to-device or channel-to-channel failover mode. Only one type of failover mode can be implemented per amplifier.

Device-to-Device Failover

All amplifiers support device-to-device amplifier chassis failover in case of fault. The redundant amplifier must be the same model as the primary amplifier. A Failover Link Cable must be connected between the primary and redundant amplifier as shown below. Connect ground to ground and Pin 1 of the primary amplifier to Pin 2 of the redundant amplifier; connect Pin 2 of the primary amplifier to Pin 1 of the redundant amplifier.

Failover is triggered by one of the following conditions:

• Chassis fault on primary amplifier
• Channel fault on the primary amplifier
• Loss of power to the primary amplifier
• Loss of CobraNet link to the primary amplifier
• Loss of Failover Link Cable
• ELD-1/speaker line fault if enabled in software

Only faults (chassis and channel) trigger the failover mechanism. Abnormal conditions that do not immediately impair audio appear as warnings, but do not trigger failover.

The redundant amplifier may be wired in parallel to the existing speaker line or it can be connected to a redundant speaker line. Relays isolate the output terminals on the secondary amplifier unit. Relays are normally open. When a configuration is received, relays close on the primary unit and remain open on the redundant unit. On failover, the relay states are reversed.

Device-to-Device Failover Wiring with Parallel Speaker Wiring

After replacing the faulty amplifier, a power cycle is required to recover from failover. This can be done either by physically repowering the amplifiers or by performing a device reset in the Vocia software via the amplifier test tab. The amplifiers are required to be reset within 10 seconds of each other in order for the primary device to resume control.

Channel-to-Channel Failover

All amplifiers support channel-to-channel failover. This is configured in the Vocia software in the amplifier’s general setting as 1:1 Failover. In this configuration, channel pairs can be specified and adjacent channels will act as a redundant backup. Channel 2 will act as a backup for channel 1. For the VA-4030 and VA-4030e models, channel 4 will act as a backup for channel 3.

Additionally, the VA-4030 and VA-4030e amplifiers support 3:1 channel redundancy. This is configured in the Vocia software in the amplifier’s general setting as 3:1 failover. In this configuration channel 4 will act as a redundant backup for channels 1, 2 or 3.
1:1 or 3:1 channel failover is triggered by one of the following conditions:

• Heatsink fault (over temperature)
• Short circuit fault
• Channel failure fault
• ELD-1/speaker line fault if enabled in the software

The redundant channel may be wired in parallel to the existing speaker line or connected to a redundant speaker line. The primary amplifier module will resume control after the fault condition is cleared and the unit is re- powered.
