With an RCA adaptor, you can use a resistor on the positive side. I would recommend using an attenuator with 23 resistors for each channel up to 5K because gain might not be equivalent for all volume levels or between CD's. Pots didn't work well for me but I didn't try the expensive ones like Alps. Marchand electronics might be able to help you out if your soldering iron is rusty. If you're lucky, a single well-chosen resistor just might do the trick.
Power matching while bi-amping
I want to by-amp with a Hafler 500W for the low end and a Rotel 70W for the high. Can I just put an appropriate sized resistor in series on the Hafler side to match volume levels? I would think this would work. And wouldn't it be better to put the resistor before the Hafler, so it isn't amplifying the full signal?

My old attenuator is available along with solid RCA Y-connectors. All it would require an extra pair of ICs. It is a stereo attenuator ranging from 1k to 4k and has additional 3-way switch that adds another 3k, 6k or nada. All in a cheesy, small DIY box. The attenuator, itself, was professionally assembled. $100.00 plus shipping is a giveaway. [email protected] |
