Registered. Hi Mike, Generally you always want to place an isolation transformer at the end of the line, not on the source side. So in this case you would place it directly in front of the sub (between the cable and the sub).

There is the commonly accepted version of directionality: in most audio quality shielded connections, compared to standard coax cables, the negative terminal has its own inner conductor and the metal shield is only connected to ground at one end , which defines the direction of the cable.
The arrow points in the direction of the signal. It should therefore point out of the receiver and into the subwoofer.
Imagine using a Y-splitter to separate two different paths, but in reverse. This happens inside the receiver. Now that the left and right signals are combined into a single channel, the appropriate sound can be directed to the subwoofer.
Connect the subwoofer to the AV receiver with a subwoofer cable (RCA cable) by routing the cable from the receiver’s subwoofer output to the subwoofer’s line input. Klipsch subwoofers can be connected via the LFE channel, the white RCA connector, or in a stereo pair using both the white and red RCA connectors.
Connecting Your Subwoofer
Most subwoofers have both a left and an amp; correct entry. Usually it doesn’t matter which one you use. Some people will buy a “Y-adapter” or “splitter” so that a single cable can feed both subwoofer inputs.
Are Nordost cables directional? Yes, Nordost cables are directional. This is especially true for unbalanced (RCA) connections since the shield is only connected at the source or output end.
In fiber optics, polarity is directional; Light signals travel from one end to the other through a fiber optic cable. The transmit signal (Tx) of a fiber optic link at the end of the cable must match the corresponding receiver (Rx) at the other end.
What happens when speakers are wired backwards? Swapping the speaker wiring results in them being out of phase. Phase cancellation causes certain frequencies in the output to be reduced and degrades audio quality. It also negatively affects the stereo imaging of the speakers.
Dual input allows the subwoofer additional sensitivity adjustment. Normally, using a mono LFE subwoofer signal from its processor would suffice. So if you have a processor with very low output power, you can use a Y-splitter. Using both inputs with the same mono signal doubles the subwoofer sensitivity.
In order to properly connect a powered subwoofer, an RCA “splitter” cable (“Y” cable) is not required. Any single standard RCA or subwoofer cable should work just fine.
Sub outputs are usually just 1 phono RCA connector as the signal is Mono, also called the LFE channel, the X. 1 in denoting a 5.1 or 7.1 surround setups. If there are further subwoofer outputs on the surround receiver, these also in mono, it is possible to connect several subwoofers.
Subwoofer cables are basically the longer, more powerful versions of RCA cables. They have thicker insulating material and shielding to protect them from interference and noise that can affect your audio quality. They also use thicker wire to avoid power loss.
Therefore, subwoofer cables play a role as they improve the sound quality by adding reinforced shielding to the cable, which serves to enhance the analog signal sent through the wires and reduce the audio hum that would otherwise be generated.< /p>
The preferred method of connecting a subwoofer is through the subwoofer output (labeled SUB OUT or SUBWOOFER) on a receiver using a Low-Frequency Effects (LFE) cable. Almost all home theater receivers and processors, and some stereo receivers, have this type of subwoofer output.
