Description
• Designed for high-level
(speaker) signals only
• Detects input signal from
CH. 1 (L) only
• Using DC Offset or Signal
Sensing methods will turn the
"Remote" terminal into a +12V
turn-on output.
• Multiple amplifiers can be controlled
from a single HD-RLC using a non-
duplex phone line splitter and multiple
phone cables.
