SPECIAL CONTROLS FOR THE XL-4165M
The following instructions apply to the model XL-4165M only. You will not find these controls on
the other models in this series.
Fig.15 2 - 4 Channel Input Mode
Fig.16 Rear Channel Crossover
MODE Switch
Matches the input from the Source Unit to that of the amplifier, either 2 or 4 Channel. This elimi-
nates 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. Must
use rear inputs.
AUX INPUT NOTE: The MODE switch must be in the 2-Channel position in order to use
the 3.5mm AUX input
Rear X-OVER Switch
Activates the Low Pass Filter (LPF). The LPF is variable from 40Hz-400Hz. FULL runs the rear
channels full range without any filter
HPF (High Pass Filter) Adjustment
When you are using coaxial or component speaker system, this allows you to adjust high-pass X-over frequency
from 40Hz to 400Hz. To get better sound quality from coaxial or component speaker system, we recommend the
frequency should be higher than 80Hz. Make sure the X-OVER switch is positioned at “HPF”.
NOTE: The HPF circuit is always active on the front channels of the XL-4165M.
