Sorry I dont know what L-pad or T-pad means when refering to vol control type.It has 2 transformers on it,2 sets of jumpers 1x 2x 4x 8x and I believe the turn knob has 12 clicks or positions.
I expected to get the 2 ohm reading fromt all the speakers in parallel,I just diddnt expect to see it again after coming out of the volume control on its way to the amp.This is whats got me stumped.thanks,B-
Follow Ups:
A pad is a large, high power pot that goes between the amp and speaker. The pad is constructed so that the amp 'sees' a constant load resistance regardless of the volume setting. I have used one to control the volume of a remote speaker.A pad that can handle 25 watts is about the size of a lemon. What doesn't go to the speaker gets wasted as heat.
What resistance do you get on the amp side of your volume control with no speakers connected? Can you post any pics?
At the 1x jumper setting its about 4ohms.at 2x its 5ohms,at 4x its 8 ohms,at 8x its 10ohms.the ohms did not change when turning the volume control.Its about the size of a lemon,fits into a standard single gang switch box.Thanks for your time! Brant-
Well, I'm stumped.The volume control in the link below is clearly for use with only one set of stereo speakers. I've never used one of these and never saw one except after installation.
The other person that responded to your original message described a safe way to connect that many speakers to one amp. I would go with that, measuring the ohms of the network before connecting it to the amp.
Best,
