Notes
• 4 AWG wire (8 AWG minimum)
• Install 20A fuse at (+) battery post
• 4 AWG wire (required)
• 18 – 12 AWG wire capacity
• See Turn On Mode for more info
• Accepts 200mV – 4V input voltage
• See Input Mode for more info
• Same signal that is connected to
CH. 1&2 inputs
• Unaffected by the amplifier's filters
• Operates as an attenuator only:
Fully counter-clockwise = Level Muted
Fully clockwise = Level Unaffected
• Multiple amplifiers can be controlled
from a single HD-RLC using a non-
duplex phone line splitter and multiple
phone cables.
CH. 1&2 Bridged (+)
• Minimum impedance load:
Stereo mode ≥2 ohms
Bridged mode ≥4 ohms
• 16 – 8 AWG wire capacity
CH. 1&2 Bridged (–)

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.
