Poor Bass Performance From Full Range Speakers connected to the IPS-1

•Make sure that your preamp does not have the bass (tone control) level turned down.

•Many surround preamplifiers have controls which can direct all the bass to subwoofers or let your main speakers play the full range. Make sure that the preamplifier has been correctly set. If you are not using a subwoofer, set the speaker options to “Large” where possible.

•Check that the speaker wires have been connected correctly: Make sure that the positive of each speaker connects to a positive output of the amplifier, and the negative of each speaker connects to a negative output. If one speaker is wired incorrectly, than it will be “out of phase” with the others, resulting in poor bass performance. In this condition, the speakers' energy is fighting the other rather than combining.

Turn-on and turn-off thumps

•Plug the amplifier into an unswitched AC outlet, and use the SIGNAL position of the turn on switch at the back of the amplifier. This will allow the amplifier to turn on and off silently.

“Hum” Noises in the Speakers

This problem is more than likely caused by a “ground loop” in your system, rather than a fault in the IPS-1. Follow these steps to isolate the main cause of the hum, there may even be more than one. Remember to turn off all components in your system, including the IPS-1, before disconnecting or connecting any cables.

•Remember to turn off all components in your system, including the amplifier, before disconnecting or connecting any cables during troubleshooting.

•Try to have all of your equipment on the same electrical outlet or circuit. Group all the low power com- ponents (preamp, CD player, DVD etc.) on a single outlet or power strip. This is provided that the overall current draw from your equipment does not exceed the rating of the outlet or breaker.

•Disconnect all cables which come from outside the room, and check if the hum goes away. This includes such connections as cable TV, satellite TV, or roof top antennas. Make sure that they are disconnected where they first enter the room, so they are making no connection to the preamplifier or the TV, or any other component. If the hum is caused by the cable TV line, then you will need a “ground loop isolator.” This is an inexpensive device fitted in line with the coaxial cable feed. Contact your cable company or your Emotiva Dealer for assistance.

•Disconnect all connections from the preamplifier to your TV, VCR or DVD.

•As a test, disconnect any other component which has a grounded power cord.

NOTE: Never remove the ground pin from any power cords (if present). This is very dangerous.

•If the hum persists, disconnect all the source components one at a time from the back of the preampli- fier, until you identify the problem.

•Try moving the speaker cables away from any power cords. Try just one speaker, connecting it to each amplifier channel and see if one channel is bad.
