VORTEX SILVER SERIES V8

1.1 Welcome To CAMCO

Established in 1983, CAMCO has gained worldwide experience with professional 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 per-

1 WELCOME

formance, 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.

VORTEX

SILVER SERIES

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!

2.2 The Amplifier

The V8 amplifiers offer a power output of:

4900 W peak per channel @ 4 Ω 5300 W peak per channel @ 2 Ω 10600 W peak in Mono Bridge @ 4 Ω 10600 W peak in Parallel Mono @ 1 Ω

Using a bipolar class H high efficiency power amplifier output stage. For a complete overview of rated power data please refer to chapter 8 Specifications.

The V8 power amplifier is fitted with Dual Voltage Switched Mode Power Supply (SMPS) with automatic voltage range selection for 120 V / 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 five main advantages over more traditional power amp systems:

1. Integrated Remote Control

2. Extreme fast and accurate monitoring of all amplifier parameters

3. Fast detection of failures

4. Very fast triggering of protection features

5. Very detailed indication of failures on the display

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, the 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 INSTALLATION

3.3. Mains

3.3.1 Mains supply

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. Only use mains cables with original Neutrik powerCON® 32 A connectors for safety reasons.

Please do NOT use much larger mains breakers than recommended here and especially do NOT connect several V8 amplifiers to one single (very large) breaker.

Always respect this rule of thumb for good installation practice for guaraneeing long term reliable, robust and safe operation:

One V8 – One breaker

As soon as the amplifier is connected to mains, the primary capacitors are charged through the inrush current limiter. At the same time the the auxilliary power supply is activated, generating a 5 V standby voltage to the main controller and the display. This allows powering up the main SMPS from the display or remotely via U

NOTE: Turning the amplifier off from the user interface (display) does not disconnect the amplifier from mains. Disconnecting the amplifier from the mains can only be achieved by physically removing / disconnecting the mains cable. The mains cable therefore has to be freely accessible at all times. Attention: Never unplug the powerCON® connector while the amplifier is playing music. Always turn the amplifier off from the display menu (see chapter 4.2) before disconnecting the powerCON® connector.

Alternatively, you can disconnect the amplifier from the mains via an external all-pole disconnection (e.g. a mains breaker).

Disconnect the mains cable during a lightning storm or when the amplifier remains unused or unsupervised for a prolonged period of time. If a power cut occurs while the amplifier is switched on, it will restart automatically once the mains distribution has been restored. All settings prior to the loss of power will be maintained.

VORTEX

SILVER SERIES

3.3.2 Inrush current limitiation

The V8 has a special processor dedicated to limit the mains inrush current.

This limiter will take action anytime: – when connecting the amplifier to the mains through the mains cable – when switching the amplifier on through an external mains breaker – the mains voltage was lost for at least 4 half-cycles or more (e.g. a short

voltage drop)

This limiter will confine the mains current to a value smaller than 17 A

*: maximum rms value of inrush current over one half-cycle of the mains voltage according to DIN EN

55103-1.

3 INSTALLATION

NOTE: Even under normal conditions the mains current can reach levels up to 32 A / 64 A (230 V / 120 V) and even higher for very short periods of time. This could cause lamps to flicker if connected to the same mains as the amplifier. 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!

3.3.3 Mains power consuption and current draw

Due to the huge output power of the V8, the mains current draw can get very high when demanding large output powers. Please refer to following table for an overview of mains currents and power cunsuption under different operating conditions.

Mains current draw and power consumption @ 230 V, 50 Hz

Measured with pink noise with crest factor of 12 dB to represent typical music signal. For 120 V mains operation, the current values can be multiplied by 2. *: duration limited by FuseProtect limiter (set @ 24 A)

Please note that the values given here are typical values only, measured on a standard 230 V / 50 Hz outlet. The actual mains current draw can vary depending on the music signal and the mains characteristics (especially the mains impedance) of any specific installation.

The integrated FuseProtect limiter will limit the average mains current draw to values between 24 A down to 8 A (selectable in 1 A steps).

This allows to control the average (long-term) mains current draw of your installation, while at the same time guaranteeing full power headroom for dynamic music signals. This means that even if the FuseProtect limiter is set to low average values, the short term mains current draw can still reach very high levels, especially when delivering huge output power with very dynamic music signals.

Please see chapter 4.6.5 for more information on the FuseProtect limiter.

This effectively doubles the current capability of the amplifier, allowing to connect lower output impedances. In this mode only the channel A input signal is fed to both amplifiers. The channel B input signal is not used / ignored. The loudspeaker loads can then be connected to either the channel A or the channel B output SPEAKON® connectors (we still recommend to always use both). This mode is useful when for example 3 identical loudspeakers are to be operated with the same power.

USER MANUAL

VORTEX SILVER SERIES V8

In this mode the channel B amplifier stage processes the identical input signal than channel A, but with reversed phase. The loudspeaker load must then be connected between the two positive channel outputs (pin 1+ and pin 2+) using a specially configured SPEAKON® connector / cable. This effectively doubles the maximum output voltage. But please note that this also doubles the minimum allowed loudspeaker impedance Zmin. As in parallel mono operation, only the channel A input signal is fed to both amplifiers. The channel B input signal is not used / ignored.

WARNING: In Mono Bridge Operation RMS output voltages can be as high as 280 Vac. 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.

4.5 Power Amp Protection Systems

4.5.1 Clip Limiter

If the maximum output level is langer than the amplifier can deliver, the Clip Limiter (if active) will reduce the output signal in order to limit distortion. The clip limiter algorithm works in a forward driven and clip signal dependent approach.

The Clip Limiter works on each channel independently (except for the two mono-operation modes). The Clip Limiter has three different modes (Off, Slow and Fast) which can be selected in the settings menu.

The Clip LED sensitivity on the display is designed to be very responsive and accurate. This means that you will still see the Clip LEDs light up, even if the clip limiter is working correctly. This allowes the user still to asess if there is real clip, even if the clip limiter does prohibit audible distortion. The remaining (and indicated) clip is then very small and usually low enough to be audibly perceive as "clean" or undistorted signal, compared to a disabled clip limiter.

4.5.2 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 not. If the power transistors are back in their SOA, the channel is automatically unmuted again.

4.5.3 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. 100 °C, the main SMPS is switched off as an emergency protection. The thermal protection status of the amplifiers are indicated in the signal monitor section of the display.

4.5.4 DC Protection

Each output of the power amp is constantly monitored for persistent DC voltage levels. If the 10 V threshold voltage is exceeded at any of the outputs, the corresponding channel will be automatically switched off. A DC issue can be located in the output stage, the driver stage, or at the input of the amplifier.

Output Stage

When a persistent DC voltage is located at an output stage, the main

4 OPERATION

SMPS will be permanently switched off. This will be indicated on the display.

Driver Stage / Amplifier Input

When a DC voltage is located at the driver stage or the input stage, only this channel’s output stage is muted and the volume set to zero. The other channel continues to operate normally. After a short time the channel is unmuted again and the volume increased again. This will be shortly indicated in the Signal Monitor section. of the display

4.5.5 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!).

4.5.6 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.

4.6 Mains Protections

4.6.1 Inrush Current Limitation

Within 2 seconds of the V8 amplifiers being connected to the mains, the inrush current limiter will charge the primary capacitances in a controlled way, limiting the maximum mains current during startup.

4.6.2 Mains Overvoltage Detection

The mains overvoltage detection is always operative. When the mains voltage exceeds approx. 267 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.

4.6.3 Mains Surge Overvoltage Protection

The V8 is fitted with a varistor unit, protecting the SMPS from sporadic surge overvoltages coming from the mains distribution.

If active, this protection is indicated by a orange LED behind the dust cover (on the right side). If this LED is not lit, this means that the amplifier has already suffered significant overvoltages surges and that the varistor protection needs to be exchanged.

4.6.4 Mains Failure Detection

Mains Failure Detection is always operative. When the mains supply is interrupted for approx. more than 4 mains cycles, the amplifier will detect and display a mains voltage loss. When the mains voltage returns to a normal value, a soft start occurs and the amplifier returns to normal / previous operation.

P.20

USER MANUAL

VORTEX SILVER SERIES V8

VORTEX

SILVER SERIES

4.6.5 Fuse Protection

When driving the V8 at very high output levels over a longer period of time (i.e. several seconds and minutes) the average mains current draw can become very high. In such situations, the FuseProtect limiter will reduce the output signal in order to prevent the external mains breaker from tripping. But this limiter in turn will not affect the output signal on dynamic music signal and short current peaks, thus guaranteeing the full available peak output power. Due to the very large output power of the V8, this limiter has been set to a

4 OPERATION

maximum average mains input current of approx. 24 A.

This design choice has been made to achieve the best compromise between mains breaker tripping protection and long term output power capabilities of the V8. This choice allows the V8 to deliver more output power over a longer time period, which it is easily capapable of. But in turn this also means that mains breaker tripping still can occur when driving the V8 at very high output levels over a longer time period.

If repeated mains breaker tripping is an issue, the V8 offers the possibility to reduce the average mains current level down to 8 A if needed (in 1 A steps). Typically a value of 18 A is safe for use with a 16 A C-type mains breaker. Please note that the FuseProtect limiter only controls the average mains input current, not the short term peak input current. This means that with very dynamic music signals the (short term) input current can still reach very high levels, which can be very demanding for a mains distribution, even with this limiter set to low values. See also chapter 3.3.3.

If active, this limitation is indicated in the display’s Signal Monitor and also by a red LED behind the dust cover (approx. in the top middle of the dust cover).

4.7 Main SMPS Protections

4.7.1 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.

4.7.2 Overload Protection

In case of extremely high output levels with heavily clipped output signals and low loudspeaker impedances < 3 Ω, this additional protection will reduce the amplifier stage output current limitation very quickly. If activated, this indicates that the amplifier is running close to it’s absolute maximum power capacity. In normal operation (no clipping or only slight clipping) this protection should never be activated. If active, this protection is indicated by a white LED behind the dust cover (on the top left side of the dust cover).

NOTE: Please reduce the input level if you see this LED flashing.

4.7.3 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.

4.8 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.

Additionally, the SMPS-On-LED and the FuseProtect-LED are oriented in a different direction, so that they might not be easily visible when facing the amplifier. But if you look slightly from the bottom (as on the picture) these LED’s should still be clearly visible.

4.10 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.
