Problem: No output at all

•Verify that you really have no output, and that you should have output. (Subwoofers reproduce only very low frequencies. If you happen to be playing something without low frequency content, then nothing will come from the subwoofer. In addition, since low frequency sound has very little localization information, if your main speakers also produce low frequencies, it may be difficult to notice the contribution from the subwoofer with some program material.)

•Verify that the subwoofer output on your source equipment is active and configured correctly, and that the output is active in the particular mode you are using with the content you are using. (Some combinations of content, processing mode, and configuration, don’t use the subwoofer. For example, some decoders don’t use the subwoofer at all when playing stereo content in some modes.) If the subwoofer produces output in any mode with any source material, then the subwoofer and connections are probably working correctly and the problem lies with your source component configuration or program material

•Verify that you have power.

•If you have power and signal, but still have no output, then please contact

Emotiva Technical Support.

Problem: Excessive hum or noise

•Check your signal source.

•Verify that all cables are plugged fully in, that the connectors fit tightly, and that the cables and connectors are in good condition.

•Try repositioning cables. If you have signal cables running near power cables, try moving them further apart. (This is especially important with unbalanced cables.)

•If you are using unbalanced connections, try higher-quality cables with better shielding. If that reduced but fails to eliminate the hum, consider trying balanced cabling (especially for long runs or where runs next to power cables are unavoidable).

•Some audio equipment (especially vacuum tube type) has a high output impedance, which makes it inherently sensitive to picking up hum and noise, especially if

only unbalanced connections are provided. This is also true for some electronic crossovers (especially passive models). It is essential that signal cables used with such equipment be kept short, of good quality, and not run near power cables.

•Some difficult installations may require a balanced connection to completely eliminate hum and noise.
