FOR EQUIPMENT THAT CONNECTS TO THE POWER MAINS

1. CAUTION: If the power cord of the device is equipped with an earthing contact, then it must be connected to an outlet with a protective ground. Never deactivate the protective ground of a power cord.

2. If the equipment has been exposed to strong fluctuations in temperature (for example, after transport), do not switch it on immediately. Moisture and condensation could damage the equipment. Do not switch on the equipment until it has reached room temperature.

3. Before connecting the equipment to the power outlet, first verify that the mains voltage and frequency match the values specified on the equipment. If the equipment has a voltage selection switch, connect the equipment to the power outlet only if the equipment values and the mains power values match. If the included power cord or power adapter does not fit in your wall outlet, contact your electrician.

4. Do not step on the power cord. Make certain that the power cable does not become kinked, especially at the mains outlet and/or power adapter and the equipment connector.

5. When connecting the equipment, make certain that the power cord or power adapter is always freely accessible. Always disconnect the equipment from the power supply if the equipment is not in use or if you want to clean the equipment. Always unplug the power cord and power adapter from the power outlet at the plug or adapter and not by pulling on the cord. Never touch the power cord and power adapter with wet hands.

6. Whenever possible, avoid switching the equipment on and off in quick succession because otherwise this can shorten the useful life of the equipment.

7. IMPORTANT INFORMATION: Replace fuses only with fuses of the same type and rating. If a fuse blows repeatedly, please contact an authorised service centre.

8. To disconnect the equipment from the power mains completely, unplug the power cord or power adapter from the power outlet.

9. If your device is equipped with a Volex power connector, the mating Volex equipment connector must be unlocked before it can be

removed. However, this also means that the equipment can slide and fall down if the power cable is pulled, which can lead to personal injuries and/or other damage. For this reason, always be careful when laying cables.

1. Unplug the power cord and power adapter from the power outlet if there is a risk of a lightning strike or before extended periods of disuse.

2. The appliance is not to be used by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge.

3. Children must be instructed not to play with the device.

4. If the power cord of the device is damaged, do not use the device. The power cord must be replaced by an adequate cable or assembly from an authorized service center.

CAUTION:

To reduce the risk of electric shock, do not remove cover (or back). There are no user serviceable parts inside. Maintenance and repairs should be exclusively carried out by qualified service personnel.

The warning triangle with lightning symbol indicates dangerous uninsulated voltage inside the unit, which may cause an electrical shock.

The warning triangle with exclamation mark indicates important operating and maintenance instructions.

Warning! This symbol indicates a hot surface. Certain parts of the housing can become hot during operation. After use, wait for a cool-down period of at least 10 minutes before handling or transporting the device.

Warning! This device is designed for use below 2000 metres in altitude.

Warning! This product is not intended for use in tropical climates.

INTRODUCTION

The I AMP is a 4-channel power amplifier in a 19" rack format, specifically developed for installations of CURV-500-Systems. The flat design with class-D topology and DSP control has a highly efficient switch mode power supply and a frequency response of 10 Hz - 22 kHz. Each channel features parametric EQ and delay and provides 240 watts RMS at 4 ohms with a total harmonic distortion of less than 0.01%.

The I AMP is easily and intuitively operated via a push-and-turn dial and a high-contrast, easily readable OLED display. It is equipped with a soft start and low-noise temperature-controlled fans and protected against direct current, overloading, overheating and short-circuiting. The balanced inputs are XLR sockets and terminal block connections. The I AMP can power up to six CURV-500 satellites or one CURV500ISUB subwoofer per channel via its Speakon-compatible output jacks or terminal block connections. Presets for speakers from the CURV500 series are pre-installed. PC software for management of the I AMP is available to download from the product page at WWW.LD-SYSTEMS.COM.

EXIT

To exit the selection menu and show the main display, turn the MENU dial to EXIT (light background) and confirm by pressing the MENU dial.

To set up a 70 V installation with the CURV 500 I AMP and CURV 500 satellites you require the LD Systems SmartLink adapter for 70 V applications LDCURV500SLAT (available in black and white, please note the instructions in the user manual for the LDCURV500SLAT); if you wish to use the speakON-compatible speaker output of the CURV 500 I AMP you require speaker cables with specially configured speakON-compatible plugs, since two amplifier channels can be connected simultaneously in bridge mode in conjunction with the relevant speaker preset. As an alternative to speakON-compatible plugs, you can use terminal block connectors (supplied, for configurations see diagram CONFIGURATION OF SPEAKER OUTPUTS or label on the amplifier, recommended for speaker cables 2 x 1.5 mm²). Select the preset corresponding to the number of satellites per SmartLink adapter as described under PRESET, then connect the CURV 500 I AMP and the CURV 500 SLAT SmartLink adapter. It is advisable not to combine SmartLink adapters with differing numbers of satellites due to the different preset settings. The maximum number of SmartLink adapters connected per bridge channel is derived from the number of CURV 500 satellites per SmartLink adapter.

Examples:

1 CURV 500 satellite per SmartLink adapter 70 V = maximum of 24 SmartLink adapters (24 x 20 W = 480 W max.)

Speaker preset 1xC500-70V

2 CURV 500 satellites per SmartLink adapter 70 V = maximum of 12 SmartLink adapters (12 x 40 W = 480 W max.)

Speaker preset 2xC500-70V

The speakON-compatible sockets and the terminal block connectors are wired in parallel. In bridge mode (BTL = Bridge Tied Load) / 70 V operation, the speakON-compatible sockets B and D may NOT be assigned; this also applies to the minus pins of the terminal block connections. For signal control, please note that the input routing can be freely configured (see ROUTING). A combination of two bridged amplifier channels (bridge mode) for controlling 70 V SmartLink adapters and controlling, for example, two CURV 500 ISUB speakers is possible in normal mode (e.g. channel A/B bridge mode – channels C and D in normal mode). Select the appropriate speaker presets.
