Input Switch - DLS DD Series Owner's Manual

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".

Input Switch

Matches the input from the Source Unit to the amplifiers. This eliminates the use of "Y" adapters and provides a cleaner
input signal. When the 2-Channel mode is selected, both front and sub outputs will operate with only one pair of low level
RCA inputs.
AUX INPUT NOTE: The MODE switch must be in the 2CH position in order to use
the 3.5mm AUX input
1) Using the 2CH Mode on the DD33-40 requires input signal to the Front Input Connector.
2) Using the 3CH Mode on the DD33-40 requires both the Front Input and Subwoofer Input to be used. This will allow for fading
between the Front and Rear/Subwoofer Outputs.
