Carver px1450 User Manual

Once the amplifier has been installed and wired into the system, you are ready to use it. Here are some
tips to help you get the most from it.

• Verify that the switches (Output Configuration/Input sensitivity) have been set to the mode that you want.

• Verify that the Signal Smart Standby circuit threshold is set at the level you want.

• When you power the system up for the first time (out of the carton), it’s a good idea to start with all of the

amplifier level controls turned down, then advance them slowly, one at a time, so that you can confirm that each
amplifier channel is operating normally.

• Be sure that the Input Level controls are set sufficiently high to allow the preceding device to drive the amplifier

to full output. For most installations, this is wide open (fully clockwise).

• Once you have established settings, it is a good idea to mark them down, either on paper, or on pieces of tape or

sticky-dots attached to the amplifier’s panel.

• In bi-amplified (multi-amp) systems, it is a good idea to start with the low-frequency amplifiers turned off or

down, and to check each frequency range from highest to lowest to ensure that each loudspeaker component is
operating correctly.
