Check for porper polarity
Pay close attention to the polarity on the rear panel binding posts. It is critically important that you match plus and minus (red and black) of the GCA Series Power Amplifi er to the plus and minus of your speaker. Carefully observe the polarity.

Be careful when connecting a subwoofer
Locking binding posts
Most subwoofers have low level inputs only, as in an RCA or XLR connector. Some subwoofers have high level inputs where the output of the amplifi er can be connected as an input to the subwoofer. Generally there is no problem. In a few rare instances there may be a problem, whcih will show itself as problematic if the amp’s protection comes on after hooking up the sub. REL subwoofers and some Sunfi re subwoofers can be problematic. Please check with the factory or your dealer if you encounter these subwoofers or any problems.
These binding posts, on the rear panel of the GCA Series Power Amplifi er, will accept either spade or banana type connectors. To use a spade or forked connector, simply unscrew the binding post, place the tongs of the spade over the threaded binding post and tighten the outer barrel of the binding post. It is permissible to us a wrench to tighten the binding post down.
Connecting a banana style
Do not ground the outputs
Plug it into a power source
The banana style connectors should be inserted into the center hole on the rear of the binding post. The PS Audio binding post is a unique locking design for banana style connectors. You should not attempt to insert a banana connector into the GCA Series Power Amplifi er’s binding post while the binding post is locked closed. To insert a banana style speaker cable connector, loosen the outer barrel of the GCA Series Power Amplifi er’s binding post, insert the banana connector and then tighten. Note that once this has been tightened, the banana connector is locked securely in place. Do not attempt to remove the banana connector without fi rst loosening the outer barrel of the binding post.
Make sure that neither the + nor the – terminals of the amplifi er come in contact with each other, or ground, or anything other than the speaker terminals when the amplifi er is on. This will shut the amp off and place it in a protection mode.
Plug the GCA Series Power Amplifi er into the power source using the AC power cable you selected. It is advisable to use as short a power cable as possible to the GCA Series Power Amplifi er. We do not recommend plugging the GCA Series Power Amplifi er into an extension strip or plug extender unless it is of the highest quality and heavy duty design, such as the PS Audio Juice Bar or device with similar properties.
Push the front panel logo to turn it on
Turn your equipment back on. Make sure everything is powered up properly with the GCA Series Power Amplifi er between the AC receptacle and your AV equipment.
Make sure the preamplifi er or surround processor that is feeding the GCA Series Power Amplifi er is turned on fi rst. Then, press the front panel PS logo on the GCA Series Power Amplifi er to power up the GCA Series Power Amplifi er. There is a normal 2 second delay for the amplifi er once powered up.
At this point you should be ready to enjoy the benefi ts of the GCA Series Power Amplifi er and enjoy!
