1.3 The Amplier
The VORTEX is a Class-H power amplier with a power output of:
VORTEX 200V 3,2 kW per channel @ 4 Ω
VORTEX 6 3 kW per channel @ 2 Ω
1 WELCOME
VORTEX 4 2 kW per channel @ 2 Ω
VORTEX 2.6 1,3 kW per channel @ 2 Ω
VORTEX power ampliers are tted with Switched Mode Power Supplies (SMPS),
which signicantly reduces the weight and size (only 2U) of the amplier. Using
SMPS, the 3 symmetrical supply voltages (2 symmetrical supply voltages for
VORTEX 2.6) of the power amplier are more stable than the power supplies
used in conventional ampliers.
6,4 kW in Mono-Bridge @ 8 Ω
6,4 kW in Parallel-Mono @ 2 Ω
6 kW in Mono-Bridge @ 4 Ω
6 kW in Parallel-Mono @ 1 Ω
4 kW in Mono-Bridge @ 4 Ω
4 kW in Parallel-Mono @ 1 Ω
2,6 kW in Mono-Bridge @ 4 Ω
2,6 kW in Parallel-Mono @ 1 Ω
The VORTEX also uses a microprocessor for controlling and monitoring
the power amp. This 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 amplier
for performing specialised tasks within a complex audio system. Users can
adapt the power amp to meet their specic audio requirements before use.
Controls mounted on the front and the rear of the VORTEX allow the different
functions to be accessed.
Since some of the externally mounted controls have multiple functions, it is
important that users should familiarise themselves thoroughly with the entire
range of controls and programmable features before using the power amp.
If you have any questions regarding features and/or functions of your VORTEX,
CAMCO will be pleased to offer you further information. Alternatively, contact
your dealer or distributor.

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 – Part 3-11: Limits
– Limitation of voltage changes, voltage uctuations and icker in the
public low-voltage supply systems – Equipment with rated current more
than 75 A and subject to conditional connection”. If in any doubt, 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!
3.2 On/Off Switch
NOTE: This switch does NOT disconnect the amplier from mains.
The switch initiates start-up by activating the current limiting function. As soon
as the power amplier is connected to the mains power supply, a voltage is
supplied to both the line-lter and the fused input of the controllable rectier.
Disconnecting the amplier from the main power supply can only be achieved
by physically separating the amplier from the mains by pulling the mains plug.
The mains plug therefore has to be freely accessible. Disconnect the mains
plug from the mains during a lightning storm or when the amplier remains
unused or un-supervised for a prolonged period of time. Alternatively, you can
disconnect the amplier via an external all-pole disconnection from the mains.
If a power cut occurs while the amplier 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.

3.4 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 efciency of the cooling 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.
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 connected to the ground of the
mains supply. In order to avoid ground loops, this connection can be separated
via a resistor. The ground potential of the power amp and the ground of the
loudspeaker always remain connected to the ground of the mains supply
regardless of the setting of this switch.

Removing or taping the mains connector ground is illegal and dangerous.
3.6 Optional Feature
Could be activated with future released software versions.
3.7 Mode Indicators
On the front panel there are two yellow LEDs to indicate the mode that is set.
In stereo mode none of them will be lit. In Parallel-Mono the (PM) LED will be lit

The output terminals of the two channels are congured in parallel using an
internal relay. The (single) load is connected either to the output of channel A
or to that of channel B (as if in stereo). While the total output of the amplier
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-Input is
active. The channel B-Input is inactive – turn the volume on channel B down to

The second channel processes the same input signal, but with reversed phase.
The (single) load is connected between the two positive channel outputs using
a suitable connected SPEAKON connector. While the total output of the amplier
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-Input is active – turn the volume on channel B 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 specic cables may only be manufactured by qualied
suppliers/personnel. All cabeling or rewiring work must be carried out by
qualied personnel.

WARNING !
SPEAKON connectors marked with the lightning ashes indicate high voltages that are potentially life threatening.
Wiring to these terminals requires installation by an instructed person or
the use of ready-made leads or cords.
Custom wiring should only be carried out by qualied personnel.
To prevent electric shock, do not operate the amplier with any of the
conductor portion of the speaker wire exposed.
NOTE:
For reasons of safety and performance, use only high-quality fully insulated speaker cables of stranded copper wire. Use the largest wire size that
is economically and physically practical, and make sure the cables are no
longer than necessary.
3 INSTALLATION / 4 OPERATION
IMPORTANT:
When connecting speaker cabinets in parallel, always use all the contacts
in both SPEAKON connectors. If not, this may cause permanent damage to
the connectors and considerably reduce performance.
4.1 Controls
4.1.1 Volume Control
A microprocessor-controlled DCA (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.
Using a DCA instead of the “conventional” VCA signicantly reduces distortion
and, at the same time, it improves the noise characteristics. A volume control
with 41 notched settings controls the DCA via a microchip.
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 modes whereby only channel A is active.
Set the volume to zero before turning on the amplier to prevent the occurrence
of sudden high volume levels which may cause damage to your hearing and/or
the speakers.
The volume controls are also used to set the CAI address. (See 5.2.2 CAI Address
Settings)

4.2 Indicators
4.2.1 On LEDs (multifunctional)
Under normal operation, after the amp has started, the green On LEDs are
permanently lit. A variety of different sequences of ashing LEDs are used to
indicate other operating states and errors in the relevant channels of the power
amp. (See 6.1 Flashing sequences for On LEDs)
USER MANUAL
VORTEX 6, 4, 2.6 and 200V
P.17
Page 19
4.2.2 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 over a 4 Ohm resistor.
If the amplier 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)
P.18
4 OPERATION
4.2.3 Clip LEDs (multifunctional)
The colour of the bi-coloured (green/red) LED changes between red, green and
yellow depending on the load and the signal modulation conditions. (Yellow is
created by a mixture of red and green light).
The intensity of the green light is dened by the current passing through
the output stage of each channel (lowest brightness is proportional to
approximately 1 A, the maximum brightness reects 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.
USER MANUAL
VORTEX 6, 4, 2.6 and 200V
4.3 Power Amp Protection Systems
4.3.1 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 the two
mono-operation modes). To disable the Clip Limiter, see 4.1.3 Limiter Switch.
4.3.2 Under Impedance Limiter
As a result of incorrectly connected or defective loads, under impedance or even
short circuits may occur in one or both power amp channels.
The microprocessor constantly calculates the load impedance at the output
channels. If an impedance of less than 1,33 ohms/channel (2,7 ohms/channel
for VORTEX 200V) 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 Impedance Limiter is active, the corresponding
channel’s On LED is turned off. (See 6 Troubleshooting)
4.3.3 SOA Protection
To ensure that the power transistors are only used in the Safe Operation Area
(SOA), the SOA-protection in stereo mode switches back the rail voltages of the
respective power stage. In mono modes the rail voltages of both channels are
switched back.
Page 20
4.3.4 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.
4.3.5 DC Protection
Each output of the power amp is constantly monitored for persistent DC voltage
levels. If the 3 V threshold voltage is exceeded at any of the outputs, the main
SMPS will shut down and the channel will be automatically switched off. The
microprocessor performs a sophisticated strategy to locate the cause of the
malfunction. DC can be located in the output stage, driver stage or at the input
of the amplier.
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)
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)
Amplier Input
When DC is located at the input stage only the DCA of the affected channel
is muted. The other channel continues to operate normally. If the DC signal
at the input vanishes, the microprocessor will de-mute the affected channel
and the amplier will work as usual again.
4.3.6 DC Servo
To prevent DC Offset at the speaker output the VORTEX is tted with two DC
Servos. (Hence there are no capacitors in the signal path!)
4.3.7 Over Current Protection
The output stage is permanently monitored for possible current surges. 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.
4.3.8 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)
4.4 Mains Protections
4.4.1 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.
4.4.2 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 amplier
will switch off. When the mains voltage returns to nominal value, a soft start
occurs.
USER MANUAL
VORTEX 6, 4, 2.6 and 200V
4 OPERATION
P.19
Page 21
4.4.3 Mains Failure Detection
Mains Failure Detection is always operative. When the mains supply is
interrupted for about 2 mains cycles, the amplier will switch off. When the
mains voltage returns to a normal value, a soft start occurs.
4.4.4 Fuse Protection
The average mains current can peak temporarily, depending on the load
impedance and type of signal, at values several times higher than the nominal
4 OPERATION
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 amplier due to current overload, the amplitude of the input signals will
be limited.
The limitation of the input signal allows a 6 kW VORTEX power amplier to be
operated reliably from a mains power supply of 230 V/16 A (120 V/30 A).
4.5 Main SMPS Protections
4.5.1 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.
4.5.2 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)
4.6 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.

5.1 E.U.I.2 (Extended User Interface)
CAUTION! Always switch off and unplug the VORTEX from mains, before
making alterations to the E.U.I. card.
The E.U.I. card contains the Rear XLR Panel as standard. Other input cards are
available (See 5.1.1 What Are The Possibilities Using The E.U.I.2?).
5 OPTIONS
To remove the E.U.I.2 unscrew the two Phillips head screws at the left and right
end of the XLR-Panel and carefully slide out the E.U.I.2.
To ret the E.U.I.2, carefully insert it. Pay attention that the cable is not clamped.
ATTENTION! Don’t forget to tighten the screws!
5.1. 1 What Are The Possibilities Using The E.U.I.2?
The E.U.I.2 is a very powerful interface, which allows access to most of the
system parameters, such as volume, input signal, mute, output current, clip
signal, temperature and more. You can use the E.U.I.2 as a lter, remote control,
signal processing device and more… Please contact your dealer/distributor or
CAMCO to customise the E.U.I.2 according to your wishes.
5.2 CAI (CAMCO Audio Interface)
CAI is a bus system, in which all signicant device functions can be monitored
externally and remotely controlled using a master PC. Up to 99 devices can be
controlled in parallel in each phase of the bus system, which simply consists of
a two-core insulated cable. For more complex operations, the Master can serve
multiple busses. For more information, please contact your dealer or distributor.
CAI allows:
To control the output-level of each Channel independently
(exception: mono modes, only Channel A is affected)
To mute each channel independently
(exception: mono modes, only Channel A is affected)
To switch the VORTEX into Standby (and back again)
To monitor temperature, output-signal, clip, output-current.
5.2.1 Wiring
To connect the VORTEX to your CAI system use a fully-wired telephone-type
cable with RJ12 connectors. For longer distances, use higher grade cable, like
RS485, DMX512 for AES/EBU digital audio. Using the second connector, CAI
signals can be sent to other VORTEX ampliers (or to other CAI controlled
devices). A linear network topology is recommended with 100 Ohm termination
at its end. Please refer to RS485 specications.

The current selected address will be immediately displayed but not automatically stored or activated! After each turn of pot you have another 30
seconds to Timeout. You can exit this procedure without saving the new address
by briey pressing the Enter-Switch or waiting for Timeout (as described
above).
To store and activate the new address you have to press the Enter-Switch for
3 seconds. This new address is stored in an EEPROM, which holds the information
even if the amp is subsequently disconnected from the mains.
Be sure to set the CAI-Master-PC to this new address. If not, the communication
will be interrupted.
5 OPTIONS
The current address will then be displayed by the On LEDs.
Flashing of On LED channel A indicates the tens of the address
Flashing of On LED channel B indicates the units of the address
These sequences are repeated for 30 seconds (timeout). Then the On LEDs
return to their normal function.
To change CAI address, turn the appropriate volume potentiometer to the required
address (volume pot channel A => TENS, volume pot channel B => UNITS).
Example of LED sequences for different address settings:
Address
01 (factory settings) 0* ash 1* ash then short pause
25 2* ashes then short pause 5* ashes then short pause
On LED Channel A ⇒TENS On LED Channel B ⇒UNITS
NOTE: Ensure you return both pots to their original position after address
selection is complete, otherwise the amplier will change its volume level
to the new pot positions!

Unplug each speaker one-by-one. If the On LED indicates normally when
you disconnect a cable, that cable or speaker is shorted.
Take care not to use too many speakers in parallel, which would result in
an impedance that is too low for normal operation!
Indication: On LED(s) sequence
Please refer to the On LED ashing sequences table to nd out which protection
is active. High temperature will cause an attenuation of output level! DC will cause
the amp to mute or shut down.
If the On LED sequence indicates “DC, Input Signal Fault”, switch off the
VORTEX and unplug the amp to disconnect it from the signal source. If the
On LED shows the same sequence when the VORTEX is switched on again,
the amp will need to be serviced by a qualied technician.
All other On LED sequences that shut down or mute the VORTEX indicate a
serious internal fault. At this point, turn the VORTEX off, remove AC power
and have the amplier serviced by a qualied technician.
6.4 Problem: No Channel Separation
Check the mode indicators on the front panel and make sure the mode
selector on the rear panel is in the Stereo-position.
Make sure other equipment in the signal path such as mixers and
preamps are set for stereo, not mono.
6.5 Problem: Distorted Sound
Indication: On LED lit
Signal LED responding to signal level
Clip LED lit only green
A faulty speaker or a loose connection could cause this. Check the wiring
and the speakers systematically (i.e. step by step) and replace them if
necessary.
The signal source might be clipping. Keep the VORTEX volume pots at
least halfway up so that the source does not have to be overdriven.
Keep the VORTEX Volume Pots at least halfway up and try changing input
sensitivity from 1,4 V to 32 dB or 26 dB with the Gain Selector on the rear.

6.6 Problem: Hiss
Unplug the amplier input to check that the hiss is coming from the source
or from a device upstream. Erratic or popping noises indicate an electronic
fault in the offending unit.
To keep the noise oor low, operate the primary signal source at full level,
without clipping.
Avoid boosting the signal further between the source and the amplier.
6.7 Problem: Squeals and Feedback
Microphone feedback must be eliminated by the 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 stages from the signal source

11 Maintenance Information
Cleaning and servicing the inside of the aplier must never carry out by unqualied personnel. The amplier must never be opened by unqualied personnel.
Cleaning and servicing work on the inside of the amplier must only be carried
out by qualied personnel.
Qualied personnel is dened as a person who has gained specialised relevant
knowledge of electronic engineering through education, training and experience and who has sufcient knowledge of all relevant governmental work
safety regulations to be in a position to judge the safe functioning of power
ampliers 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 amplier, it has to be checked
regularly, depending on its application but at least once a year, by a properly
qualied person.
Advice on how to carry out these checks can be found in DIN VDE 0702-1 “Safety
Checks for Electronic Appliances” .
