2. INTRODUCTION Congratulations on the purchase of your new EAW Commercial power amplifier. You now own one of the finest professional audio products available - the result of exceptional engineering and meticulous craftsmanship. Please read these instructions to get the maximum performance from your new power amplifier. Each EAW Commercial power amplifier is intended for professional use.
3. FRONT PANEL FEATURES 1. POWER 5. LEVEL CONTROLS Use this rocker switch to turn the unit on or off. This connects/disconnects the AC power to the AC power transformer. These two knobs control the levels of Channels A and B. The knobs are detented to make it easy to set both controls to the same level. Usually, these controls are set all the way up. The amplifier is on when the top of the switch is pressed in. It is off when the bottom of the switch is pressed in.
4. REAR PANEL FEATURES 1. SCREW TERMINAL INPUTS 4. CLIP LIMIT The CAZ series amplifiers give you three options for connecting the input signal — these screw terminals, and XLR or 1/4” connectors via the "combination" input described below. When engaged, the CLIP LIMIT switch protects your loudspeakers from the effects of clipping. It is designed to be virtually transparent, meaning you probably won’t even notice any audible difference when the switch is turned on.
. FAN VENTS 9. POWER CORD SOCKET Do not obstruct the ventilation openings of the amplifier. 7. SPEAKER OUTPUTS Connect your speakers to these output screw terminals. The hookup diagrams on page 10 show how to connect your speakers in various ways. There are three pairs of terminals. Use the two outer pairs (CHANNEL A and CHANNEL B) when using stereo or mono modes. Here is where you connect the detachable power cord included with your amplifier.
5. OPERATION The following steps will help you set up your amplifier, and get the levels just right. GETTING STARTED 1. Be sure the amplifier’s POWER switch is off when making any connections to or from the amplifier. 2. Turn down both Level controls. 3. On the rear panel, set the SUBSONIC FILTER switch OFF and the CLIP LIMIT switch ON. 4. Determine which AMP MODE is best for your application. CONNECTIONS 1.
AC POWER REQUIREMENTS The amplifier's power cord should be plugged into an AC outlet properly configured 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 amplifiers 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.
1/4" TS Phone Plugs and Jacks 6. CONNECTIONS Use a high-quality 3-conductor shielded cable to connect the signal between the signal source (mixing console, equalizer, etc.) and the balanced inputs to the amplifier. If you are using unbalanced inputs, use a high-quality 2-conductor shielded cable. Here are some common audio connectors and their internal wiring: “TS” stands for Tip-Sleeve, the two connections available on a mono 1/4" phone jack or plug. They are used for unbalanced signals.
