Thank you for viewing. This product is a custom-length cable that can be directly inserted into an amplifier. [Transaction Flow] Please specify the cable length for each audio output in 0.1m increments, starting from 1m, and we will provide an estimate. Front[high]R/L convex = ○.○m Rear[Mid]R/L convex = ○.○m SW R/L convex = ○.○m If the estimate meets your requirements, we will add your name and specifications and change the price, so please purchase. We have set the shipping time to 4-7 days to allow for the production period, but we will ship as soon as it is ready. [Please Note] We do not support anything other than audio output cables. If necessary, please transplant from the original cable. [MOGAMI 2549] We use MOGAMI 2549, which is highly regarded as a microphone cable for recording studios. I still vividly remember being surprised by the improved high and low frequency extension and resolution when I switched from the MOGAMI 2534, which is considered a standard in my system, to 2549. [Amphenol ACPR-SRD/ACPR-SWH] ・Robust die-cast shell body ・Highly flexible boots to protect the cable ・Gold-plated contacts [Soldering] We use WBT-0800 silver solder and a temperature-controlled soldering iron, and work by inserting it into RCA jacks with heat dissipation measures. [Confirmation after production] We confirm that there are no wiring errors with a continuity check using a tester, and we also confirm that there are no short circuits before completion. We appreciate your consideration.
