![]() ![]() Unfortunately, I know several people who own soldering irons, but don't have a clue as to how to properly solder.

If it's an AUX input on a pro level mixer with a 5K or 10k input Z, and is being driven from a good, low Z AUX feed, or low Z outputs from some outboard gear then 500 ohms might give the best S/N ratio and signal summing.Īll things considered, it's really best to make your own with full consideration of the stereo output and mono input impedances, although 1k or 2k will "work" with almost anything, it may not be optimum.Īs theblue1 said "everyone should own a soldering iron". If it's a high-Z "prosumer" amp (20k to 100k input Z), then 2.5K or even more may be appropriate. Part of the problem with such summing adapters is that the isolation resistors should be chosen with the input impedance of the mono amp in mind. They are definitely not intended to connect L & R stereo outputs to a mono input. ![]() ![]() There are plenty of adapters and "Y" cables with the tip and ring connected directly to to the TS tip, but those should only be used to connect a mono output to a pair of L & R inputs. ![]() Unfortunately, they haven't offered that adapter in about 10 years. I have one each in the 1/4 inch and 3.5 mm sizes. They made the outer molded plastic "body" out of bright red plastic instead of their usual black. Radio Shack used to make a TRS to TS adapter with two internal 1K resistors. ![]()
