4. REAR PANEL FEATURES 1. SCREW TERMINAL INPUTS 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. You can connect either a balanced or an unbalanced signal here. - Page 6 6. FAN VENTS 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.

CAZ800 = 5 A CAZ1400 = 7 A CAZ2500 =10 A It is recommended that a stiff supply of AC power be used because the amplifier places high current demands on the AC line. -
Page 9: Connections
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: XLR Connectors XLR connectors are commonly wired as follows (according... -
