XL-4165M CONTROL PANEL LAYOUT
NOTE: Panel Layout and Controls may differ by model.
1. POWER/STATUS Indicator
This clear LED lights Blue when the power is on—or turns Red constantly when the built-in protection circuitry is activated. Red
indicates a problem with the system in relation to the amplifier (See Troubleshooting Tips).
2. REAR Low Level RCA and High Level Speaker Inputs
Use this Low Level 4-pin High/Low style input is where the wiring harness plugs in for the Low Level input that connects to source
units with RCA line level outputs. A source unit with a minimum input of 250mV is required for proper operation. However, this input
can accept levels up to 10Vrms.
3. REAR GAIN Control
This control is used to match the input sensitivity of the amplifier to the particular source unit that you are using up to 250mV to
10 volts.
4. MODE Switch
Matches the input from the Source Unit to that of the amplifier, either 2 or 4 Channel. This eliminates the use of “Y” adapters and
provides a cleaner input signal. When the 2-Channel mode is selected, both front and rear outputs will operate with only one pair of
low level RCA inputs. In 2CH mode, use rear inputs only.
