1.3 The Amplier

The VORTEX 3 QUADRO is a Class-H four channel power amplier with a power
output of 750 W per channel / 4 Ω load (1,5 kW in stereo / 2 Ω or 8 Ω load). These
four channels are subdivided in two stereo ampliers A/B and C/D which can be
independently set to stereo, Mono-Bridge or Parallel-Mono operation.
This feature guarantes the most exibility of the VORTEX 3 QUADRO.
It is supplied by Switched Mode Power Supplies (SMPS). These SMPS’s radically

1 WELCOME

reduce the weight and size (only 2U) of the amplier. Using SMPS, the 2 sym­metrical supply voltages of the power amplier are more stable than the power
supplies used in conventional ampliers.

The VORTEX also uses three microprocessors for controlling and monitoring
the power amp. Controlling a power amp designed for use in modern sound
systems, has four main advantages over more traditional power amp systems:

Reduced Distortion

Improved Noise Characteristics

Integrated Remote Control

Indication of protection or failures by different LED sequences

The VORTEX has been designed as an intelligent and powerful product
for performing specialised tasks within a complex audio system. Users can
adapt the power amp to meet their specic audio requirements before use.
Controls mounted on the front and the rear of the VORTEX allow access to the
functionality.

Since some of the externally mounted controls have multiple functions, it is
important that users should familiarise themselves with the entire range of con­trols and programmable features before using the power amp.

If you have questions about features of the VORTEX power amp that are not
covered by the basic descriptions in this manual, CAMCO would be pleased to
offer you further information. Alternatively, contact your dealer/distributor.

3.1 On/Off Switch

NOTE: This switch does NOT disconnect the amplier from mains.

The switch initiates start-up by activating the current limiting function.
As soon as the power amplier is connected to the mains power supply, a
voltage is supplied to both the line-lter and the fused input of the controllable
rectier. Disconnecting the amplier from the main power supply can only be
achieved by physically separating the amplier from the mains by pulling the
mains plug. The mains plug therfore has to be freely accessible. Disconnect
the mains plug from the mains during a lightning storm or when the amplier
remains unused or un-supervised for a prolonged period of time. Alternatively,
you can disconnect the amplier via an external all-pole disconnection from
the mains.
If a power cut occurs while the amplier is switched on, it will restart auto­matically once the power supply has been restored. All settings operation prior
to the loss of power will be maintained.

3.2 Precautions

When mounting or connecting the amp always disconnect it from mains.

3.3 Mounting

Use four screws and washers when mounting the amplier to the front rack rails.
For mobile use, the amplier should also be secured using the 19” mounting
elements on the rear panel.

3.4 Cooling

Under normal operation of the power amp, overheating should never be a
problem. The air is taken in from the front and out through the back, it is of
course essential that while the power amp is running air is able to circulate
around it freely.
The temperature of the cooling air will depend on the immediate environment
(e.g. an enclosed rack, direct sunlight) and on whether the front lter is clogged.
If the amp is installed in a case, the open area at the back of the case must be at
least 140 cm². This area should be in line with the amp.

3INSTALLATION

If this can not be achived a forced ventilation system has to be used.

3.5 Ground Lift

The input signal ground (pin 1 for all 4 XLRs) is tied to the ground potential in
the mains supply. Opening the ground lift switch causes this connection to be
broken. This allows ground loops that sometimes occur in practice to be elimi
nated. The ground potential of the power amp and therefore of the loudspeaker
outputs is independent of the switch setting and remains at the ground poten
tial of the mains supply.

Removing or taping the mains connector ground is illegal and dangerous.

DO NOT REMOVE MAINS CONNECTOR GROUND

IT IS ILLEGAL AND DANGEROUS

3.6 Mode Indicators

On the front panel there are two pairs of yellow LEDs (A/B, C/D) to indicate the
modes that are set to the ampliers A/B and C/D. In stereo mode none of them
will be lit. In Parallel-Mono the (PM) LED and in Mono-Bridge the (MB) LED will
be lit.

3.7 Mode Selectors

The switches AB MODE and CD MODE on the rear panel change the operating
mode of the appropriate amplier (A/B , C/D). Moving one of these switches will
shutdown the VORTEX 3 QUADRO and restart it in the new operating mode.

3.8 Basic Concepts

The VORTEX 3 QUADRO consists of two Stereo ampliers A/B and C/D. Both
of them are capable to work independently in Stereo, Mono-Bridge or Parallel­Mono. Following you will nd a description about these modes for amplier A/B
(in parenthesis the appropriate channels of amplier C/D).

The output terminals of the two channels are congured in parallel using an
internal relay. The (single) load is connected either to the output of channel A(C)
or to that of channel B(D) (as if in stereo). While the total output of the amplier
remains the same and the output voltage level is also the same as in stereo oper­ation, the minimum impedance that can be connected is reduced by half due to
the fact that current capability is doubled. Only Channel A(C)-Input is active.

NOTE: For Parallel-Mono Operation, to prevent damage of one SPEAKON
connector and to reduce loss of power because of contact or cable re­sistance, it is highly recommended to wire speaker loads using SPEAKON
connector with all contacts connected.

The second channel processes the same input signal, but with reversed phase.
The (single) load is connected between the two positive channel outputs
(1+/2+) using a suitable connected SPEAKON connector. While the total output
of the amplier remains the same, both the available output voltage and the
minimum impedance that can be connected are doubled, as compared with
stereo operation. Only Channel A(C)-Input is active
Channel B(D) down to zero.

WARNING!
In Mono-Bidge mode RMS output voltages are as high as 230 V. Wiring
to the speaker loads must conform to NEC Class 3 safety standards or its
equivalent that meets all national and local electric codes.
All customer specic cables may only be manufactured by qualied
suppliers/personnel. All cabeling or rewiring work must be carried out by
qualied personnel.

4.1 Precautions

Only connect the VORTEX amplier to an appropriate AC circuit and outlet,
according to the requirements indicated in the second row on the rating
plate.

Power Supply Data:

Voltage Mains Frequency Current

VORTEX-3-QUADRO 100 V
VORTEX-3-QUADRO 120 V 50/60 Hz 24 A 1800 W
VORTEX-3-QUADRO 220 V 60 Hz 7,8 A 1070 W

NOTE: Even under normal conditions the mains current can reach levels
up to 60 A (230 V) and 120 A (120 V), respectively; this could cause lamps
to icker if connected to the same mains as the amp. The impedance of
the AC circuit should be less than 0.157 Ohms to avoid icker according
to EN61000-3-11. (Electromagnetic compatibility – sec tion 3 – 11: limits;
limitation of voltage changes, voltage uctuations and icker in the public
LV supply; equipment and appliances consuming more than 75 A current
are subject to special conditions for connection/installation) If in any
doublt, consult your local power provider. Never attempt to measure this
impedance level with your ohmmeter. This may damage your meter and
expose you to the risk of electric shock!

Consumption

4.2 Controls

4.2.1 Volume Control

Two microprocessor-controlled DCAs (Digital Controlled Attenuator) with a
control resolution of 12 bits per channel is integrated into the signal path. This
means that the signal is not subject to an A/D followed by a D/A conversion with
associated losses. Each channel is governed by a linear potentiometer with 41
notched settings. These settings have been selected to correspond to human
hearing characteristics (logarithmically) and therefore guarantee an optimal
range of settings for practical applications. Each channel can be set individually
except when operating in mono mode whereby only ChA (C) is active.
Using an intelligent DCA control (Digital Controlled Attenuator) instead of
the “conventional” VCA results in considerably reduced distortion as well as
improved noise characteristics.

Set the volume to zero before turning on the amplier to prevent the occurrence
of sudden high volume levels which may cause damage to your hearing and/or
the speakers.
The volume pots are also used to set the CAI-address. (See 5.2.2 CAI Address

4.3 Indicators

4.3.1 On LEDs (multifunctional)

Under normal operation, after the amp has started, the green power LEDs are
permanently lit. A variety of different sequences of ashing LEDs are used to
indicate other operating states and errors in one of the channels of the power
amp. (See 6.1 On LED Flashing Sequences)

P.20

USER MANUAL

VORTEX 3 QUADRO

4.3.2 Signal LEDs

The green signal LED is illuminated when the voltage level at the output reaches
approx. 4 V; this corresponds to a power of approx. 4 W at an impedance of
4 Ohms.

The intensity of the green light is dened by the current passing through
the output stage of each channel (lowest brightness is proportional to
approximately 1 A, the maximum brightness reects the maximum output
current). The red colour indicates the amount of signal clipping in each
respective channel. If the green LED (current indicator) and red LED (clipping
indicator) light up simultaneously, the Clip LED is yellow.

4.3.3 Clip LEDs (multifunctional)

The clip LEDs are bi-coloured: green/red. Each colour indicates a different status.

If the amplier is overdriven for prolonged periods, the Clip LED will appear red
to alert the user more effectively (the green component of the LED is switched
off).
Monitoring the output current and clip via the LEDs can aid the detection of
incorrectly wired components and faults in the loudspeakers at an early stage.
(See 6 Troubleshooting)

4.4 Power Amp Protection Systems

4.4.1 Clip Limiter

If the power amp is overdriven, the clip detection circuit triggers the micro­processor. The processor reduces input signal level by controlling the DCA.
The strategy is implemented in software. For sinusoidal input signals the
microprocessor limits the input signal in such a way that non-linear distortions
of the signal never exceed 1 %.
The clip limiter can work on each channel independently (except in mono­operation). To disable the Clip Limiter, see 4.2.3 Limiter Switch.

4.4.2 Under Impedance Limiter

As a result of incorrectly connected or defective loads, under impedance or even
short circuits may be presented to the power amp channels.
In order to detect an under impedance, the microprocessor calculates the result­ant impedance. If an impedance of less than 2,66 ohms/channel is detected, the
microprocessor limits the signal to the power amp until a subsequent measure­ment indicates that impedance has risen to a safe level. Whenever the under

USER MANUAL

VORTEX 3 QUADRO

4 OPERATION

P.21

P.22

impedance limiter is active, the corresponding channel’s On LED is turned off.

(See 6 Troubleshooting)

4.4.3 SOA Protection

Whenever the power transistors leave their Safe Operation Area (SOA), the
SOA-protection in stereo mode switches back the current rail of the respective
power stage. In mono modes the rails of both channels of one amplier are
switched back.

4 OPERATION

4.4.4 Speaker Protect Limiter

Whenever the SOA protection of the power amp switches back the current rail
there could be a small clipping at the output; but the microprocessor is also
triggered by this protection and will reduce the signal level immediately to
minimise the effect.

The user can decide either to use Speaker Protect or not. If you use this amp
for low frequencies (bass / Sub bass) and you want to squeeze the absolute
maximum out of it, Speaker Protect can be switched off. For all other applications
(e.g. Full Range) it’s recommended to keep Speaker Protect switched on.

4.4.5 DC Protection

Each output of the power amp is constantly monitored for persistent DC voltage
levels. If the 3 V thresholds are exceeded at any of the outputs, main SMPS will
shut down and the channel at that output will be automatically disconnected.
The microprocessor performs a sophisticated strategy to locate the cause of DC.
If short-term DC is detected, the amplier will recover and continue to operate.
DC can be located in the output stage, driver stage or at the input of the amplier.

Output Stage

When a DC voltage is located at an output stage, the main SMPS remains
switched off. The On LEDs will show a ash sequence corresponding to this
malfunction. (See 6 Troubleshooting)

USER MANUAL

VORTEX 3 QUADRO

Driver Stage

When a DC voltage is located at the driver stage only the defective channel’s
output stage and the DCA are muted. The other channel continues to work.
The On LED of the defective channel will indicate the malfunction by starting
the relevant ash sequence. (See 6 Troubleshooting)

Amplier Input

When DC is located at the input stage only the DCA of the affected channel is
muted. (The other channels continue to operate normally). If the DC signal at
the input vanishes the microprocessor will de-mute the affected channel and
the amplier will work as usual again.

4.4.6 DC Servo

To prevent DC Offset at the speaker output the VORTEX is tted with two DC
Servos per channel. (Hence there are no capacitors in the signal path!)

4.4.7 Over Current Protection

Over current is permanently controlled in the output stage. There are two limi­ting levels of over current depending on output voltage. These limits will be set
automatically. This improves reliability without degrading sound quality when
driving complex loads.

4.4.8 Thermal Protection

The microprocessor uses several sensors in the amp in order to ascertain tem­perature data. If the microprocessor detects a temperature of more than 85 °C
at the heat sinks, the input signal on that channel is reduced. If the temperature
exceeds 100 °C, the main SMPS is switched off.
The On LED of the overheated channel will start a blinking-sequence.

(See 6 Troubleshooting)

4.5 Mains Protections

4.5.1 Inrush Current Limitation

Within 2 seconds of the VORTEX being switched on, the inrush current limiter
will increase mains current from nearly zero to nominal value. This value
depends on program material, output level and speaker loads.

4.5.2 Mains Over Voltage Detection

Mains over voltage detection is always operative. When the mains voltage
exceeds approx. 267 V (230 V operation) or 134 V (120 V operation), the amplier
will be switched off. The system will try to start in intervalls and will return with
a soft start when the regular mains voltage returns.

4.5.3 Mains Failure Detection

Mains failure detection is always operative. When the mains supply is inter­rupted for about 2 mains cycles, the amplier will be switched off. When the
mains voltage returns to a normal value, a soft start occurs.

4.5.4 Fuse Protection

The average mains current can peak temporarily, depending on the load
impedance and type of signal, at values signicant higher than the nominal
value allowed by the fuse protection.
Continuous monitoring of the fuse protection status allows the conditions that
would trigger the fuse protection to be predicted. In order to avoid shut-down
of the amplier due to current overload, the amplitude of the input signals will
be limited and by hard overloads the amp will be muted for the time.
The limitation of the input signal allows a 6 kW VORTEX power amplier to be
operated reliably from a mains power supply of 230V / 16 A (120 V / 30A).

4.6 Main SMPS Protections

4.6.1 Over Current Protection

Main SMPS (Switched Mode Power Supply) transformer current of your VORTEX
is continuously monitored. If over current occurs, the main SMPS immediately
stops working. Should there be an internal failure, this feature prevents other
parts being damaged.

4.6.2 Thermal Protection

The temperature of the main SMPS transformer of your VORTEX is permanently
monitored. If the temperature exceeds 85 °C, the microchip reduces the input
signals of both channels. If the temperature surpasses 100 °C, the main SMPS is
switched off. The On LEDs will start a blinking sequence corresponding to this
malfunction. (See 6 Troubleshooting)

4.7 Fans

The fans mounted in your VORTEX operate permanently, but as long as the
temperature remains below 40 °C, they run at their slowest speed and can
hardly be heard. The highest detected temperature from either channel controls
the speed of the fans. Above 40 °C the speed is increased until it reaches its
maximum value.

without clipping.

Avoid boosting the signal further between the source and the amplier.

6.7 Problem: Squeals and Feedback

Microphone feedback should be controlled with mixer controls. If noise

continues to build up with no microphone gain, there is a serious fault
in the signal processors or cables. Working in succession from the signal

11 Maintenance Information

Cleaning and servicing the inside of the aplier must never carry out by unquali­ed personnel. The amplier must never be opened by unqualied personnel.

Cleaning and servicing work on the inside of the amplier must only be carried
out by qualied personnel.

Qualied personnel is dened as a person who has gained specialised relevant
knowledge of electronic engineering through education, training and experi­ence and who has sufcient knowledge of all relevant governmental work
safety regulations to be in a position to judge the safe functioning of power
ampliers based on technical rules according to IEC 60065.
(IEC 60065 (Din EN 60065) Safety Requirements for Audio, Video or simlar Elec­tronic Appliances)

In order to guarantee the safe functioning of the amplier, it has to be checked
regularly, depending on its application but at least once a year, by a properly
qualied person.
Advice on how to carry out these checks can be found in DIN VDE 0702-1 Safety
Checks for Electronic Appliances.

An amplier that is considered to be unsafe must be labelled accordingly and
stored in a safe place to prevent this amplier being used mistakenly.

12 Decomissioning

During the decomissioning process of the amplier, all legally prescribed rules
and procedures must be adhered to.
