CAMCO USER MANUAL
VORTEX POWER AMP SERIES
P.8
CAMCO’s commitment to research and development, seen not just in the area
of materials and technology but also most importantly in its highly skilled and
motivated workforce, is one of the keys to its ongoing success.
With its all-new VORTEX power amp series, CAMCO is pioneering a new
dimension in professional power amp construction. The seamless combination
of groundbreaking technology with secure and proven elements is the
hallmark of the new series.
Welcome to the new world of professional power ampliers -
WELCOME TO CAMCO!
NEVER SHIP THE AMPLIFIER WITHOUT THE ORIGINAL
PACKING MATERIALS.
When shipping the VORTEX amplier, always use the original shipping carton
and packing materials. For maximum protection, repack the unit as it was
originally packed at the factory.
1.3 The amplier
The VORTEX is a Class-H power amplier with a power output of 3 kW per
channel / 2 Ohm load (6 kW in mono / 4 Ohm load) for VORTEX 6, 2 kW per
channel / 2 Ohm load (4 kW in mono / 4 Ohm load) for VORTEX 4 and 1300 W
per chanel / 2 Ohm load (2,6 kW in mono / 4 Ohm load) for VORTEX 2.6.
It is supplied by Switched Mode Power Supplies (SMPS). These SMPS’s radically
reduce the weight and size (only 2U) of the amplier. Using SMPS, the 3 symmetrical supply voltages (2- symmetrical supply voltages for VORTEX 2.6)
1.0 WELCOME
of the power amplier are more stable than the power supplies used in conventional ampliers.
The VORTEX also uses a microprocessor 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 specic 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.

3.4 Cooling
Under normal operation of the power amp, overheating should never be a
problem. 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.
If this can not be achived a forced ventilation system has to be used.
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.
3.0 INSTALLATION
3.5 Ground Lift
The input signal ground (pin 1 for all 4 XLR’s) 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 eliminated. The ground potential of the power amp and therefore of the
loudspeaker outputs is independent of the switch setting and remains at the
ground potential of the mains supply.

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 1
or to that of channel 2 (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. This mode is useful when powering 3 speaker cabinets in parallel. A load
balancing is achieved in this case.
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
both 2 channel SPEAKON connectors with all contacts connected.
3.7 Input Signal Chaining
The input signals to the XLR connectors can be hard-wired in parallel using
a switch on the E.U.I. (See 3.6.2, Switch 1, 5.1, Extended User Interface and 5.1.1,
Input Signal Parallel Switch). This serves as a replacement for an external short
XLR female - XLR male cable for parallel linking the signal inputs.

3.0 INSTALLATION
CAUTION:
Linking channels together can cause damage to system components if for
example two inputs are used with separate ‘LF’ and ‘HF’ feeds.
If the amplier is to be used for ‘LF’ and ‘HF’, ensure this switch is set to
STEREO Mode before switching on.

improved noise characteristics. The implementation is comparatively simple:
the volume potentiometers pass the relevant control information (quieter or
louder depending on the adjustment made to the potentiometers) to the
microprocessor. The microprocessor then adjusts the power amp output using
various strategies implemented in software. In addition to improved technical
parameters, this approach allows a signicant reduction in the number of
components and circuits required.
4.0 OPERATION
P.16
NOTE: Even under normal conditions the mains current can reach levels
(up to 60 A / 230 V and 120 A / 115 V); 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. Ask / inform your local power provider. Don’t even
think about measureing this with your ohmmeter. This may damage your
meter, caution - high voltage hazards!
4.2 Controls
4.2.1 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. 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 is active.
Using an intelligent DCA control (Digital Controlled Attenuator) instead of
the “conventional” VCA results in considerably reduced distortion as well as
CAMCO USER MANUAL

The volume pots are also used to set the CAI-address.
(See 5.2.3, CAI Address Settings)

A switch on the rear of the VORTEX allows the maximum amplication
attainable to be set directly in the input stage.

4.3 Indicators
4.3.1 On / Failure Indicators
4.0 OPERATION
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 6.0, Trouble Shooting)
4.3.2 Signal Indicators
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.
SpP
SpP Clip
Left position:
Clip Limiter: OFF & Speaker Protect: OFF
4.3.3 Clip / Output Current Indicators
The clip LED’s are bi-coloured: green / red. Each colour indicates a different
status.
The green section is subject to analogue control. The brightness is proportional
to the output current in the channel. The LED is visibly lit above around 1 Amp,
while full brightness corresponds to the maximum rated current. If the LED is
lit red only, no load is applied to the outputs or Clip is active with a duty cycle
of more than 10 %.
When under load, there is also a certain current that ows when controlling
the power level; the green section will be lit appropriately. If the power level is
taken to the limit, the green and red sections will appear mixed, resulting in a
shade of yellow that depends on the current. If the microprocessor detects a
clip signal with a duty cycle of more than 10 % within a time interval of 50 ms,
then it suppresses the green section so that the clip LED appears only red.
Careful analysis of the various dependencies when comparing channels that
are subject to identical control (possibly in several different power amps) will
allow conclusions to be drawn about the inherent impedances. This can aid
the detection of incorrectly wired components and faults in loudspeakers at
an early stage.
P.17
CAMCO USER MANUAL
VORTEX POWER AMP SERIES
4.0 OPERATION
P.18
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 DAC.
The strategy is implemented in software. For sinusoidal signals the
microprocessor limits the input signal level with the result that the non-linear
distortion factor never exceeds 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 one or both power amp channels. In
order to detect an under impedance, the microprocessor calculates the resultant impedance. If an impedance of less than 1.33 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 impedance limiter is active, the corresponding channel’s power LED is
turned off. (See 6.0, Trouble Shooting)
4.4.3 Speaker Protect Limiter
Whenever the Safe Operation Mode (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.
User can decide either to use speaker protect or not. When you use this amp
for low frequencies (SUB bass / bass) and you want to squeeze the absolute
CAMCO USER MANUAL
VORTEX POWER AMP SERIES
maximum out of it, switch Speaker Protect off. For all other applications (e.g.
Full Range) it’s recommended to switch Speaker Protect on.
4.4.4 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 are switched back.
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, 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 amplier will recover and continue to operate. DC can be located
in the Output stage, Driver stage or at the input of the amplier.
Output stage
When DC is located in either output stage, the amp stops the main SMPS
and mutes the amp where DC was detected. The On-LEDs will show a
different ash sequence. (See 6.0, Trouble Shooting)
Driver stage
When DC is located in the driver stage only the defective channel’s output
stage and DCA are muted. The other channel still works. The On-LED of the
defective channel will start the ash sequence. (See 6.0, Trouble Shooting)
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.
4.4.6 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!)
4.4.7 Power Amp 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.
4.0 OPERATION
4.4.8 Power Amp 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.
The power LED of the overheated channel will start a blinking-sequence
(See 6.0, Trouble Shooting)
4.5 Mains Protection
4.5.3 Mains Failure Detection
Mains failure detection is always operative. When the mains supply is
interrupted for about 2 mains cycles, the amplier will be switched off. When
the mains voltage returns to a normal value, a soft start occurs.
4.5.4 Fuse Protection
Depending on the load impedance and type of signal levels, the effective
mains current can, even during normal operation, reach a level several times
higher than its nominal value for short periods. Repeated peaks of this nature
will also cause the average value to increase. In such cases, the internal mains
fuse and external 16 A circuit breaker acts as a “bottleneck”, and would trip if the
average current remained too high for an extended period. In order to avoid
this unsatisfactory operation, the mains fuse is simulated inside the amplier
and provides the microprocessor with information. Prior to the point when the
circuit breaker would trip, a signal is sent to the microprocessor, which then
instantaneously reduces the signal level. After the known recovery time for the
fuse has elapsed, the signal is again adjusted to its normal level. This offers
reliable operation of a 6 kW VORTEX on 16 A Mains at 230 V and
30 A at 115 V.
P.19
4.5.1 Inrush Current Limitation
Within 2 seconds of the amplier 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 (110 V operation), the amplier will be switched off. When the mains voltage returns to nominal value, a
soft start occurs.

monitored. If over current occurs, the main SMPS immediately stops working.
Should there be an internal failure, this feature prevents other parts being
damaged.
4.7 Fans
The fans mounted in the 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.
4.8 Filter Cleaning
A removable lter system is provided on the air intakes to the cooling system. If the lter becomes clogged, the unit will not cool as efciently as it should and may
produce output levels that are lower than normal due to high heat sink temperatures.
To clean, gently slide the whole plastic lter assembly to the left and release from the front panel. Carefully unclip the outer moulding to reveal the lter. Clean the lter
4.0 OPERATION
with a mild dishwashing detergent and warm water. Once dry, insert the lter back into the cradle and cover with the surround moulding. Slide the whole assembly to
the right to secure onto the front panel.
Spare lter assembly’s may be ordered from your dealer.

VORTEX POWER AMP SERIES
5.1 E.U.I. (Extended User Interface)
The E.U.I. slot contains the Rear XLR Panel and the Input Signal Parallel switch
as standard. Other input cards are available (See 5.1.3 Accessories) Always switch
off and unplug the VORTEX from mains, when working on the E.U.I.
The switches described below are not readily accessible and cannot be
checked visually from the outside. To remove the E.U.I. unscrew the two Phillips
5.0 OPTIONS
head screws at the left and right end of XLR-Panel and carefully slide out the
E.U.I. To ret the E.U.I into the VORTEX, carefully insert the PCB in the guide-rail
(left/right) and slide it in.
5.1.3 Accessories
Different types of lters are available. For further information contact your
dealer or CAMCO
5.1.4 What Are The Possibilities Using The E.U.I.?
The E.U.I. is a very powerful interface, which allows access to most of the system
parameters. For example: volume, input signal, mute, output current, clip signal,
temperature and more. It makes it possible to utilise lters, remote control,
signal processing, and more… Please contact your dealer or CAMCO to
customise the E.U.I. according your wishes.
P.21
Don’t forget to replace the screws!
5.1.1 Input Signal Parallel Switch
If you want to hard-wire the XLR input connectors together on the E.U.I., just
change from Stereo to Mono using switch S1. Be careful when you do this!
(See section 3.7, Input Signal Chaining)
5.1.2 Filter On / Off Switch
If a lter is present on the E.U.I. this can be activated or bypassed using switch
S2.

5.2 C.A.I. (Camco Audio Interface)
5.2.1 Camco Audio Interface
C.A.I. 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. The master can serve several phases for larger
applications. For more information, please contact your dealer or distributor.
5.2.2 Wiring
To connect the VORTEX to your C.A.I. - system use a fully-wired telephone-type
cable with RJ12 connectors. For longer distances use high grade cable like
for RS485, DMX512 for AES/EBU digital audio. You can chain several VORTEX
ampliers using the second C.A.I. Connector on each amplier. A linear network topology is recommend with 100 Ohm termination at its end. Please refer
to RS 485 specications.
5.2.3 C.A.I. Address Settings
The C.A.I. address selection procedure will not affect the operation of the
VORTEX but whilst this procedure is active, the Volume cannot be adjusted by
using the Pots.
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!
5.2.4 To Activate CAI Address Selection Procedure
Briey press the ENTER -Switch. This push button switch (Enter - Switch) can be
accessed through the 3mm hole in the front panel located between the main
5.0 OPTIONS
power switch and the LEDs.
Enter Switch
After briey pressing the Enter-Switch the actual address will be displayed by
the power LEDs.
Flashing of Power LED channel A indicates the tens,
Flashing of Power LED channel B indicates the units of the address.
These sequences are repeated for 30 seconds (timeout). Then the Power LEDs
return to their normal function.
To change CAI address, turn the appropriate Volume Potentiometer to the
required address (Volume Pot Ch A => TENS, Volume Pot Ch B => UNITS).
To adjust the address you can use the scale markings of the
potentiometers. You will nd the digits 0,1,2,3,4,5,6,7,8,9 on the 10 scale
spacing .
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 leave 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 mains. Be sure to
set the CAI-Master-PC to this new address. If not, the communication will be
interrupted.
5.2.5 CAI Status Indicator
This green LED indicates the presence of communication between PC and the
amp.

5.2.6 Overview Or Remote Controls CAI
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 mode (and back again)
To monitor temperature, output-signal, clip, output-current.
6.1 On LED Flashing Sequences
When switching on the amp the Power LEDs ash twice accompanied by a
ash of clip LEDs. This is normal for the ‘Start’ sequence of the VORTEX.
When switching off the amp the Power LEDs ash several times followed by a
ash of clip LEDs. This is normal for the Shut Down sequence of the VORTEX.
(It is the same as the loss of the mains voltage.)
In the following table you will nd the possible LED sequences of the ON-LEDs:

Check the speaker wiring for breaks.
Try another speaker and cable.
Indication: On LED(s) sequence
The amplier is in protective muting. Refer to On LED ashing sequences table to nd out the cause for the mute.
Overheating will cause protective muting.
Check for proper ventilation. If the fan isn’t running the amplier requires
servicing.
6.4 Problem: No Sound or Sound is too Low
Indication: On LED not or sporadically lit
Signal LED off
Clip/Output Current indicator lit green or red
Under Impedance Limiter is active. The load impedance is
abnormally low or shorted.
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 -
CAMCO USER MANUAL
VORTEX POWER AMP SERIES
an impedance that is too low for normal operation!
Indication: On LED(s) Sequence
Please refer to the On LED sequence table to nd out which
protection is active.
High temperature will cause an attenuation of output level so that under
normal conditions the amp will never mute!
DC will cause the amp to mute or shut down.
Switch off the VORTEX and unplug the source from the amp’s input to
prevent DC entering the amp via the signal source. Then switch on the
VORTEX. If the On-indicator shows the same sequence, the amp will need to
be serviced by a qualied technician.
All other 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.
6.5 Problem: No Channel Separation
Check the mode indicators on the front panel.
Make sure the mode-switch 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.
On the E.U.I., check the Input Signal Parallel Switch is in the stereoposition.
6.6 Problem: Distorted Sound
Indication: On LED lit
Signal LED responding to signal level
Clip/Output Current indicator lit only green
A faulty speaker or a loose connection could cause this. Try another
speaker and check the wiring.
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.
Try changing input sensitivity from 1,4 V to 32 dB or 26 dB at the
Gainswitch.
6.7 Problem: Music Sounds Frequency Filtered
If you have installed an optional lter module on E.U.I check the lter
6.0 TROUBLESHOOTING
on/off-switch to be in off-position.
6.8 Problem: Hiss
Unplug the amplier input to conrm 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.
6.9 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 source
towards the amplier and check each device in the signal path by reducing
its gain or by unplugging it.
