SUPRA Y-Link subwoofer audio cable

Supra Sublink RCA
For single channel connection between e.g. a receiver and active sub-woofer (often called LFE channel = Low Frequency Effects). Supra Sublinks low capacitance and high noise interference immunity make longer cable routing possible, which most often is the case for sub-woofer connections. Further the low capacitance allow bass pulse build-up without flattening or slow down, the really desirable property of an excellent hifi sub-woofer sound.

Features and benefits
• Shielding - very silent from noise and microphony
• Easy to install - fits also perfect in conduits
• Low capacitance - Allows for bass pulse without flattening or slowing down
• Robust connectors - Noise immune and gold plated for a long service life
• Made in Sweden!

Why should you often use Y-split cables for an active subwoofer?

It is often an advantage to use a Y-split subwoofer cable (mono to dual-mono), even if the original signal is a mono signal. It is clear that the bass unit itself can be equipped with a double swing coil, or the subwoofer with several units. Most crossovers in subwoofers therefore perform best if both inputs are used. In practice, this usually causes the subwoofer to play a little louder at the same input signal / volume than by simply using one input. Therefore, in order to make optimal use of the subwoofer and the subwoofer has such a stereo input, we always recommend using a subwoofer split cable if no mono or LFE input is specified directly.

Supra Y-Link Subwoofer Cable - Splits singel channel subwoofer output to two mono inputs
Supra Y-Link allows for interconnection between a receiver with a single LFE channel output and an active sub-woofer without specific LFE input but instead two channel (stereo) inputs, or any other devices that is desired to feed with one single channel. Sometimes the output sound level from the sub-woofer becomes too low when feeding only one of the inputs, why we have developed Y-Link cable that branches from one to two single-ended RCA connectors, making it possible to feed both channels with the same mono signal.
