1.1 Welcome To CAMCO

Established in 1983, CAMCO has gained worldwide experience with profes- sional sound reinforcement technology. Within the audio market, CAMCO specialises in the production and marketing of high quality power amplifiers and sound systems to be used both on tour and in static installations.

The success of the LA, DL, DX, and TECTON series power amps has made the name CAMCO synonymous with professional quality, high performance, and utterly reliable power amps.

With the VORTEX power amp series, CAMCO has been pioneering a new dimension in professional power amp construction in the last decade. The seamless combination of ground-breaking technology with proven safety elements has been the hallmark of the VORTEX series.

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.

The new technologies that have been developed and applied to the proaudio industry have been substantial over the last few years, but actually it is only now that we as designers, researchers, and developers are able to take the next steps in building a more coherent future with tools that really integrate together.

The ancient cultures developed an understanding of our world by a realisation of the individual elements that are at the core of all things. These were described as the Five Elements. We see the development of technology and the resulting products in the same way. Today CAMCO follows the same pattern of realisation, our five elements are ; Efficiency, Power, Networking, Signal Processing, and Design.

As the five elements come together to form the One, we can see that the evolution of amplifiers is now reaching the point where we can truly call the amplifier a universal audio platform, not just X-amount of power output, as impressive as it is in terms of true power per channel across the V8, but a Network station, an advanced Signal Processing station, a multicore like distribution centre, too, allowing hundreds of channels of processing and data to be sent and received which all can be controlled from one platform.

Thus the efficiency of the complete package now shows itself to be much more than just a power amplifier. The CAMCO VORTEX SILVER SERIES V8 is evolving into much more; it is in fact becoming the evolution of today´s pro-audio needs and conditions. It will be the bench mark for building the future.

Welcome to the new world of professional power amplifiers –

WELCOME TO CAMCO!

2.1 Unpacking

Please unpack and inspect your new amplifier for any damage that may have occurred during transit. If damage is found, notify the transportation company immediately. Only you as the consignee may initiate a claim for shipping damage. CAMCO will be happy to cooperate fully as needed. Please save the shipping carton as evidence of damage for the shipper’s inspection.

Even if the amplifier has arrived in perfect condition, save all packing materials for any future transport of the unit.

When shipping the V8 amplifier, always use the original shipping carton and packing materials. For maximum protection, repack the unit as it was originally packed at the factory.

NOTE: NEVER SHIP THE AMPLIFIER WITHOUT THE ORIGINAL PACKING MATERIALS.

2.2 The Amplifier

The V8 amplifiers offer a power output of:

4400 W peak per channel @ 4 Ω (3800 W rms) 4400 W peak per channel @ 2 Ω (4000 W rms) 8800 W peak in Mono Bridge @ 4 Ω (7600 W rms) 8800 W peak in Parallel Mono @ 2 Ω (8000 W rms)

using a bipolar class H high efficiency power amplifier output stage.

The V8 power amplifier is fitted with Dual Voltage Switched Mode Power Supply (SMPS) with automatic voltage selection for 120V / 230 V operation, which significantly reduces the weight and size (only 2U) of the amplifier. Using SMPS, the seamlessly regulated symmetrical supply voltages of the power amplifier are more stable and efficient than the power supplies used in conventional amplifiers.

The V8 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

The V8 has been designed as an intelligent and powerful amplifier for performing specialised tasks within a complex audio system. Users can adapt the power amp to meet their specific audio requirements before use. The display mounted on the front of the V8 amplifier allow the different functions to be accessed. Since there are a lot of parameters available, it is important that users should familiarize themselves thoroughly with the entire range of settings and programmable features before using the power amp. If you have any questions regarding features and/or functions of your V8 amplifier, CAMCO will be pleased to provide you with further information. Alternatively, contact your dealer or distributor.

3.2 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 efficiency of the cooling will depend on both the immediate environment (e.g. an enclosed rack, direct sunlight) and that the front filter 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 cannot be achieved, a forced ventilation system has to be used.

3.3 Wiring

3.3.1 Analog Input - XLR Connection

XLR: Pin 1 = Ground (or lifted via 15 Ω resistor)

Pin 2 = Hot (in-phase) Pin 3 = Cold (out of phase)

Always use symmetrically (balanced) shielded cable to connect the amplifier.

3.3.2 Dual Channel Operation

Two fully independent amplifier channels (normal operating mode).

3.3.3 Parallel Mono Operation

Parallel operation of the two channels together.

The output terminals of the two channels are configured 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 dual channel). While the total output of the amplifier remains the same and the output voltage level is also the same as in dual channel 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 zero. This mode is useful when for example 3 identical loudspeakers are to be operated with the same power.

3.3.4 Mono Bridge Operation

One-channel mono bridged operation.

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 amplifier remains the same,both the available output voltage and the minimum impedance that can be connected are doubled - like being operated in dual channel operation. Only channel A-Input is active – turn the volume on channel B down to zero.

WARNING: In Mono Bridge Operation RMS output voltages are as high as 260 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 specific cables may only be manufactured by qualified suppliers/personnel. All cabling or rewiring work must be carried out by qualified personnel.

WARNING! SPEAKON connectors marked with the lightning flashes 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 qualified personnel.

To prevent electric shock, do not operate the amplifier with any of the conductor portion of the speaker wire exposed.

NOTE: For reasons of safety and performance do only use high-quality fully insulated speaker cables of stranded copper wire. Use the largest wire size that is economically and physically practical. Make sure that the cables are not longer than necessary.

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.

3.4 Mains supply

When mounting or connecting the amp, always disconnect it from mains. Only connect the V8 amplifier to an appropriate AC circuit and outlet in accordance with the requirements indicated in the second line on the rating plate.

Exemplary rating plates for a mains supply of 120/230 V AC 50/60 Hz.

Power Supply Data:

Voltage Mains Frequency Current Power Consumption

120/230 V

50/60 Hz 30/15 A 2100 W

NOTE: Even under normal conditions the mains current can reach levels up to 20 A (230 V), and 40 A (120 V), respectively; this could cause lamps to flicker if connected to the same mains as the amp. The impedance of the AC circuit should be less than 0,157 Ω to avoid flicker according to EN61000-3-11 “Electromagnetic compatibility – Part 311: Limits – Limitation of voltage changes, voltage fluctuations, and flicker

in the public low-voltage supply systems – Equipment with rated current ≤

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!

4.2 Power On-Sequence

As soon as the V8 amplifer is connected to the mains power supply, it will start the Power On-Sequence. The display will show the V8 logo followed by the Power On-Screen.

This is the screen used to switch the amplifier on/off. Please touch MENU and ENTER simultaneously to switch on the amplifier or touch any of the touch-sensitive elements to activate the display backlight.

NOTE: Turning the Amplifier off does NOT disconnect the amplifier from mains.

The switch initiates start-up by activating the current limiting function. As soon as the power amplifier is connected to the mains power supply, a voltage is supplied to both the line-filter and the fused input of the controllable rectifier. Disconnecting the amplifier from the main power supply can only be achieved by physically separating the amplifier 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 amplifier remains unused or unsupervised for a prolonged period of time. Alternatively, you can disconnect the amplifier from the mains via an external all-pole disconnection. If a power cut occurs while the amplifier is switched on, it will restart automatically once the power supply has been restored. All settings prior to the loss of power will be maintained.

4.8 Power Amp Protection Systems

4.8.1 Clip Limiter

If the power amp is overdriven, the clip detection circuit triggers the microprocessor. The processor reduces the 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, use 2.5 Clip Limiter Screen.

4.8.2 SOA Protection

To ensure that the power transistors are only used in the Safe Operation Area (SOA), the SOA-protection would mute the corresponding channel. If the power transistors are back in their SOA, the channel is automatically unmuted again.

4.8.3 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 corresponding 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 amplifier.

Output Stage

When a persistent DC voltage is located at an output stage, the main SMPS remains switched off. This will be indicated in the amplifier‘s display.

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. This will be indicated in the amplifier‘s display.

Amplifier 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 unmute the affected channel and the amplifier will work as usual again. This will be shortly indicated in the amplifier‘s display.

4.8.4 DC Servo

To prevent DC Offset at the speaker output, the V8 amplifiers are fitted with two DC Servos (hence there are no capacitors in the signal path!).

4.8.5 Overcurrent Protection

The output stage is permanently monitored for possible current surges. There are two limiting levels of overcurrent depending on output voltage. These limits will be set automatically. This improves reliability without degrading sound quality when driving complex loads.

4.8.6 Thermal Protection

The microprocessor uses several sensors on the amplifier‘s heatsinks in order to ascertain temperature data. If the microprocessor detects a temperature of more than 85 °C at the amplifier‘s heat sinks, the input signal on that channel is automatically reduced. If the temperature exceeds 95 °C, the corresponding channel is muted. If the temperature exceeds approx. 110 °C, the main SMPS is switched off as an emergency protection. The thermal protection status of the amplifiers are indicated in the display.

4.9 Mains Protections

4.9.1 Inrush Current Limitation

Within 2 seconds of the V8 amplifiers being switched on, the inrush current limiter will increase mains current from nearly zero to nominal value. This value depends on programme material, output level, and speaker loads.

4.9.2 Mains Over Voltage Detection

Mains Over Voltage Detection is always operative. When the mains voltage exceeds approx. 265 V (230 V operation), or 134 V (120 V operation) , the amplifier will switch off. When the mains voltage returns to nominal value, a soft start occurs.

4.9.3 Mains Failure Detection

Mains Failure Detection is always operative. When the mains supply is interrupted for about 2 mains cycles, the amplifier will switch off. When the mains voltage returns to a normal value, a soft start occurs.

4.9.4 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 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 amplifier due to current overload, the amplitude of the input signals will be limited. The limitation of the input signal allows the V8 power amplifier to be operated reliably from a mains power supply of 230 V/15 A (120 V/30 A).

4.10 Main SMPS Protections

4.10.1 Overcurrent Protection

Main SMPS (Switched Mode Power Supply) transformer current of your V8 amplifier 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.

4.10.2 Thermal Protection

The temperature of the main SMPS transformer of your V8 amplifier is permanently monitored. If the temperature exceeds 85 °C, the main SMPS is switched off. The amplifier‘s display will indicate a main SMPS error in this case.

4.11 Fans

The fans mounted in your V8 amplifier 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.

4.12 Filter Cleaning

The air intake on the front of your V8 amplifier is fitted with a removable filter system. If the filter becomes clogged, the unit will not cool as efficiently as it should and may result in reduced output levels.

V8 Filter Assembly 1 Clip Aperture 2 Injection Molded Cradle 3 Foam Filter 4 Injection Molded Surround 5 Injection Molded CAMCO Badge

For changing the filter, no tools are required: first, gently slide the whole plastic filter assembly a few millimeters to the left and lift it from the front panel. Next, beginning on one of the long sides, carefully unclip the molded surround (4) from the cradle (2) and then carefully pull the CAMCO badge (5) out of the four fastening holes with both hands. Remove the foam filter (3) and clean it with a mild dishwashing detergent and warm water. Once dry, replace the foam filter carefully into the cradle and repeat the dismantling procedure in reverse. Insert the five pins on the filter frame into the clip apertures (1) and slide the filter carefully to the right to secure.
