Set-Up Adjustments; Input Gain Adjustment - DLS DD31T Owner's Manual

INPUT Gain Adjustment

This control allows you to match the input level of the amplifier to the output level of your head unit. Matching the input can be
accomplished in three simple steps:
1. Set the volume of GAIN on the amplifier to Min (completely counter clock wise).
2. Turn on the head unit and adjust volume to 2/3 maximum, and set the BASS to zero.
3. Adjust the GAIN control clockwise until the sound just begins to distort, then back o slightly to cut distortion and operate
at optimum gain.
Remember, the GAIN control is not a volume control . Ignoring the three steps above may leave you with damaged
speaker and/or a damaged amplifier.
BASS EQ Control
This special feature is designed to provide you more powerful sound quality, and it allows you to increase the bass output up to
+18dB at 45Hz (Sub Channel only). Keep in mind more is not always better. Setting the control to the max (18dB) may stress the
amplifier and woofer and could result in damage.
NOTE: More is not always better. By turning the BASS EQ all the way up to 18dB you can overwork the
amplifier and send the unit into thermal protection.
LPF (Low Pass Filter) Adjustment
Adjust the LPF frequency for your subwoofer(s) operation. Using the LPF control, adjust the Low Pass Frequency to limit the
amount of midrange going to your subwoofers.
