LIMITED AMPLIFIER WARRANTY STATEMENT

HOW TO OBTAIN WARRANTY SERVICE

Diamond Audio Technology, Inc. (DAT) warrants this amplifier to be free from defects in material and workmanship for the lifetime of the

amplifier in its original installation provided the amplifier was purchased from and installed by an authorized DAT retailer. Amplifiers

purchased from but not installed by an authorized DAT retailer carry a one (1) year parts and labor guarantee.

This warranty is not transferable and applies only to the original purchaser of this amplifier in its original installation. Original

purchaser must reside in the United States and register the amplifier with DAT within 30 days of installation. Warranty registration

information can be found at www.diamondaudio.com or by calling 866-328-2834. Original purchaser must be able to provide proof of

purchase and installation with the sales receipt from the authorized DAT retailer that sold and installed the amp.

Should a manufacturing defect occur in the first three (3) years of the above said warranty period, DAT will replace the defective product

with new product of the same or equivalent value and performance. Should the defect occur after the first three (3), DAT will (at its

discretion), repair or replace the defective product or parts with new or remanufactured product for as long as the amplifier is in its original

installation. Damage or failure caused by any of the following is not covered under this warranty policy: negligence, improper use, abuse,

product modification, unauthorized repair attempts, accident, acts of God, misrepresentations by DAT retailers, and improper/inadequate

packaging during return shipping.

Warranty is void if serial numbers have been removed, altered or defaced or if protective seal is broken.

In the event a DAT product should require service, you should visit the authorized DAT retailer you purchased the product from and they

can expedite your claim. All claims must fall into the guidelines listed above and be accompanied by a copy of the original sales and

installation receipt from that authorized DAT

retailer.

Product returned for warranty service must be freight-prepaid, properly packaged and clearly marked with the Return Authorization (RA)

number issued by DAT. Any product returned to DAT that is improperly packaged, does not have a RA number clearly marked on the package,

or never received a RA number; may be refused upon delivery. DAT does not assume responsibility for lost or misdirected product.

Repair or replacement under this warranty is the exclusive remedy of the consumer. DAT shall not be liable for any incidental or

consequential damages for breach of any expressed or implied warranty on this product. Some states do not allow the exclusion or

limitation or incidental or consequential damages, or allow limitations on how long an implied warranty lasts, so the above limitations or

exclusions may not apply to you. This warranty gives you specific legal rights and you may also have other rights that may vary from state to

state.

Customers outside the United States should contact their local sales office to obtain information on pricing, exchange unit availability,

CAUTION

Prolonged exposure to sound pressure levels in excess of 100 dB can cause permanent

hearing loss. Diamond Audio D6 amplifiers produce enough power to make most speaker

systems exceed that level. Please exercise restraint and protection during their operation

in order to preserve your ability to enjoy their fidelity for years to come.

DC CONNECTIONS

D6 amplifiers need proper power and ground connections to deliver maximum performance and efficiency. This is typically the least understood part of the installation process. The D6 power supply is completely defendant on current, not voltage, so it is truly regulated by nature. Voltage drops due to poor connections or grounding practices will only cause the amp to pull more and more current to sustain output. This increased current draw causes unwanted noise, thermal issues, and will eventually make the amp shut down or cause the vehicles electrical system to fail.

The gauge of the power and ground cables must be capable of handling the current needed by the entire system. Power and ground cables must be of the same gauge. If the alternator is not capable of supplying enough power for both the vehicle AND the audio system, a high output alternator should be installed for best performance.

Batteries and High Output Alternators…

The battery in your car is a chemical storage device for electrical energy generated by the alternator. It is capable of briefly supplying high currents for cold starting the vehicle as well as powering other important electrical loads either partially or entirely for a limited period when the engine is off.

In order to supply the power required for ignition, lighting, large audio systems etc. a car needs its own efficient, reliable, and constantly available source of energy. When the engine is stopped, the battery is the vehicle’s energy source. When the engine is running, the alternator is the on-board “electricity generating plant.” It is the job of the alternator to supply power to all current-consuming loads (including the audio system).

Alternator output, battery capacity, and power demand of all electrical loads and systems must be matched as ideally as possible so the entire system is reliable and trouble-free in operation.

PROFESSIONAL INSTALLATION

To achieve maximum performance and life time warranty coverage (see warranty statement), Diamond Audio strongly recommends that a factory authorized Diamond retailer professionally installs your new amplifier. The D6 amplifier is an awesome component with category leading technology, proper attention must be taken during installation to ensure optimum performance. The authorized Diamond retailer you purchased your amplifier from has the training, expertise, and tools for proper installation. If you decide to install your amplifier yourself, please read this manual through to become familiar with the amplifiers install and set up procedures.

MOUNTING

D6 Reference Amplifiers do not utilize any fan driven cooling system. Care must be taken to provide a sufficient flow of air around the amplifier for the thermal management system to operate at peak efficiency. Air should be able the flow over the top and sides of the amp freely. Adding a fan to your system can be beneficial in keeping your amp cool. A minimum 2 inches of space around the amplifier is recommended to ensure proper air flow. Never mount any amplifier where it can get wet. Water damage is not covered under warranty.

Mounting your amplifier inside an enclosure is not a good idea unless that enclosure is equipped with ventilation fans to circulate fresh air through the enclosure.

The D6 amplifier features adjustable mounting flanges. Should they need to be moved to a different location, remove the self-tapping screws on the bottom of each mounting flange. Move the flange to the desired location. Carefully tighten the self-tapping bottom screws. Warning - Over tighten these screws will cause stripping of the thread and/or screw head.
