Q - P O W E R 14 | 1 POWER AMPLIFIER WELCOME! 1. Welcome to CAMCO Thank you for choosing CAMCO products. You are now the proud owner of a very advanced CAMCO Amplifier. The technologies used in your amplifier are of the latest generation and designs delivering a far reaching set of results across all functions. 1.1 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.
2 World’s first DSP controlled Power Supply in Professional Audio. The all new Q-POWER 14 with DSP controlled PFC power supply is the flagship of the series, offering up to 14 000 W of undistorted power in an very compact and lightweight package. The development of a DSP controlled, active PFC (Power Factor Correction) enables the Q-POWER 14 to use the mains power supply much more efficiently than conventional designs.

3 Q - P O W E R 14 | POWER AMPLIFIER M A I N S S U P P LY 3. Mains 3.1 Mains Supply The Q-POWER 14’s power supply is a true wide-range SMPS with active power factor correction (PFC). This means that it can be operated anywhere in the world without the need of any manual voltage range setting. When mounting or connecting the amp always disconnect it from mains.
Q - P O W E R 14 | 3 POWER AMPLIFIER M A I N S S U P P LY 3.4 Mains Voltage Range To guarantee the best amplifier performance all over the world the power supply internally works with three mains voltage “grids” or “ranges”. These are: > 100 VAC (Japan) > 110-127 VAC (North and parts of South America) > 200-240 VAC (Europe and the “Rest of the World”) For each grid there is a set of highly optimised control parameters to get the maximum power performance achievable.

Q - P O W E R 14 | 3 POWER AMPLIFIER M A I N S S U P P LY 3.7 FuseProtect™ Limiter - Mains Circuit Breaker selection The integrated FuseProtect™ feature will at all times limit the mains current draw to the maximum current handling capabilities of the specific programmed MCB for each mains voltage range. When shipped, the Q-POWER 14 is programmed with default MCBs for each mains voltage range.
4 4. Mounting Use four screws and washers when mounting the amplifier to the front rack rails. For mobile and touring use, the amplifier should also be secured using the 19” mounting elements on the rear panel. 4.1 Mounting Dimensions Q-POWER 14 Q - P O W E R 14 | POWER AMPLIFIER INSTALLATION 4.2 Cooling The air is taken in from the front and streams out through the back. It is essential that while the amplifier is running the air is able to circulate around it freely.

Q - P O W E R 14 | 6 POWER AMPLIFIER OPERATION 6. Operation 6.2 Controls 6.1 Indicators 6.2.1 Volume Control A volume control with 41 notched settings controls the audio signal. 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.
6 Q - P O W E R 14 | POWER AMPLIFIER OPERATION 6.3 CAMCO USB MCB Updater The CAMCO USB MCB Updater offers a set of different commonly used mains breakers, and allows to permanently store it inside the amplifier. The stored MCBs will be maintained even after power loss. The application also can display a graph showing in detail each MCBs tripping characteristic.
Q - P O W E R 14 | POWER AMPLIFIER PROTECTIONS 7. Protections 7.1 Power Amp Protection Systems 7.1.1 Clip Limiter If the maximum output level is higher than the amplifier can deliver, the Clip Limiter (if active) will reduce the output signal in order to limit distortion. The Clip Limiter works on each channel independently, but can only be activated for the channel pairs A/B or C/D respectively. The Clip LED sensitivity on the display is designed to be very responsive and accurate.
7 7.1.9 High Frequency Protection All outputs are permanently monitored for high-frequency high output signals. Continous output of 22 kHz sine-wave signals at full scale is permissible, but higher frequencies at very high output levels might trigger this protection. If detected, the corresponding amplifier module will be switched off for a few seconds and restarted again. 7.2 Mains and Power Supply Protections 7.2.

Filter Cleaning 8.1 Removing the Filter System and Cleaning The air intake on the front of your Q-POWER 14 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 lead to reduced output levels.
9 Q - P O W E R 14 | POWER AMPLIFIER VOLUME CONTROL SECURITY COVER 9. Volume Control Security Cover 9.1 Mounting the Volume Control Security Cover It is possible to install a solid protection over the volume controls to prevent intentional or unintentional changes of the amplifier volume settings. ! WARNING! Disconnect the amplifier from the mains before installing the cover.
Q - P O W E R 14 | 10 POWER AMPLIFIER TROUBLESHOOTING 10. Troubleshooting Here are some tips and tricks which might be useful when encountering weird amplifier behaviour during use. If none of the advices work please contact CAMCO for further support. > If this doesn’t help unplug the mains cable and wait for at least 2 minutes, then replug the mains cable and switch the amplifier on.
10 10.6 Signal and Clip LED of one or more channels are red intermittently This LED pattern indicates that the corresponding amplifier channel has gone to short-term protect mode. This can have multiple reasons: a) Short-circuit protection has been triggered (3 sec. protect duration). > Check the loudspeakers and cables for possible short-circuits. b) Overtemperature protection has been triggered (undefined protect duration, depending on temperature rise and fall).
