A WORD ABOUT PROFESSIONAL INSTALLATION...

We, the folks at Diamond Audio, highly advise the use of a factory authorized

installation technician. System performance ultimately depends on proper

installation. Your D7 Series amplifier is an awesome component that deserves

to be professionally installed. If this last-chance plea for dealer assistance

doesn't sway you, the following instructions will make the installation of your

new amplifier a little easier.

Before starting your installation, remove the negative battery cable before

working on the positive terminal to prevent a short to ground. If a short does

occur, current will continue to flow until the short is opened, the main fuse

blows, or the wire melts (possibly taking out any nearby flammable object,

wire loom, etc. causing a fire or possibly even a tear in the fabric of time and

space). Reconnect the negative terminal after all connections have been made.

MOUNTING YOUR AMPLIFIER

WARNING — AMPLIFIERS GENERATE HEAT!

You can mount your amplifier in any position, even upside down.

However, airflow must be maintained. Do not install your amplifier

under carpets or behind airtight panels. Let the amplifier breathe.

Without air circulation, your amplifier will reduce its power

output to protect itself.

D7 Professional Reference Amplifiers utilize a forced-air 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 is drawn

into the system along the sides of the amplifier, over the circuit board, through

the bottom heat sink and is exhausted through the vents on the end panels.

Be sure to allow at least 2 inches of space around the amplifier. Never mount

your amplifier where it can get wet. Water damage is not covered by the
