EAW CAZ1400 Benutzerhandbuch

 – CAZ Series

The amplifi er's power cord should be plugged into an AC 
outlet properly confi gured with the voltage required for 
your particular model.

Be sure the AC outlet can supply enough current to allow 
full power operation of all the amplifi ers plugged into it. 
The outlet should be a three-prong socket that matches the 
power cord.

WARNING: Bypassing the plug’s safety ground pin can 
be dangerous. Don’t do it!

The AC current demand of an amplifi er varies depending 
on several factors, including the load impedance, the crest 
factor, and the duty cycle of the program material. Under 
typical conditions reproducing rock music where musical 
peaks are just below clipping, the amplifi ers require the 
following average currents.

CAZ800 = 5 A

CAZ1400 = 7 A

CAZ2500 =10 A

It is recommended that a stiff supply of AC power be used 
because the amplifi er places high current demands on the 
AC line. The more power that is available on the line, the 
louder the amplifi er will play and the more peak output 
power will be available for cleaner, punchier bass.

If you have more than one amplifi er sharing an AC outlet, 
you should avoid turning them all on at the same time. 
Rather, sequence them on, one at a time, to prevent 
popping the circuit breaker (due to in-rush current).

The power amplifi er is fan cooled. Air is drawn through the 
rear panel vents, to cool down the amplifi er heatsinks, and 
then expelled through the front panel vents.

When installing, be sure to allow suffi cient air space 
around the front and rear of the amplifi er for adequate 
cooling for the heatsinks. Leave at least one rack space 
above and below, and at least 6 inches behind and in front 
of the chassis to allow proper ventilation.

If the amplifi er should overheat, a thermal switch turns 
off the power amplifi er, allowing the heatsink to cool 
down. Once the amplifi er has cooled to a safe operating 
temperature, the thermal switch resets and reactivates 
the amplifi er. If this should occur, identify the cause of the 
problem and take corrective action. For example:

• Provide 

better 

ventilation

•  Install a fan in the rack to move more air

•  Make sure the amplifi er is not overloaded with too 

low of a load impedance or by a short circuit on the 
speaker line

The CAZ amplifi ers are designed to be mounted in a 
standard rack. They require two rack spaces (2U = 3.5”). 
They also require 15.75” depth inside the rack, including 
the rear support brackets. When designing your rack, put 
the heavier items at the bottom and the lighter items 
toward the top.

Secure the front panel of the amplifi er to the front of 
the rack using four screws with soft washers to prevent 
scratching the panel. In addition, because of the weight 
of the amplifi er, you must secure the rear support brackets 
of the amplifi er to the back of the rack. You could use a 
support rail or shelf across the back of the rack, or angle 
brackets attached between the rear support rails and 
the rear rails of the rack. This is recommended for all 
components mounted in a rack that is going to be moved 
frequently.

Usually, your amplifi er will not require regular maintenance 
for normal use. However, you can do several things to keep 
it in good operating and cosmetic condition.

•  Testing: Periodically test your system for proper 

performance. A simple test is to play a CD through 
it using well-defi ned, articulate, wide-range 
program material. Listen to ensure all drivers are 
working properly and for any evidence of distortion 
or other extraneous sounds. Test at several volume 
levels: very low, normal, and high.

•  Cleaning: Use only a clean dry cloth to dust off 

and clean the surface. Turn off the power to the 
amplifi er while you do this.
