4.OPERATIONS
Selecting input voltage
APX and DPX amplifiers accommodate a wide range of signal input voltages (0.2V to 8V). This wide range is split up into three ranges, which are accessible through switches located in the “Gain” area of the amplifier.
•0.2V-0.6V selects an input sensitivity range between 200mV and 600mV.
•0.6-2V selects an input sensitivity range between 600mV and 2V.
•2V-8V selects an input sensitivity range between 2V and 8V.
The gain rotary control operates within these voltage windows.
Note:
Most decks, even 4V and 5V units do not operate at full output voltage. This requires the switch to be set in the 0.6-2V range.
Setting the operating level
The gain switches allow you to set the nominal operating level of the amplifier from 0.2 to 8V for RCA inputs or 500mV to 5V for speaker level inputs. This wide adjustment range accommodates virtually any source unit brand.
Once you set the correct range using the IVS, you must adjust the gain to match the amplifiers sensitivity to that of the source unit. The gain control is not a volume control. It exists only to allow an amplifier to be used with different models and brands of head units.
Improving bass sound
The amplifiers feature a narrow-frequency band bass boost circuit (known as “high- Q”). Acting much like an equalizer, the bass boost control lets you tune low-frequency audio response to compensate for a less than ideal subwoofer enclosure design. The added boost produces rich, full bass tones that are normally difficult to reproduce in the car audio environment.
•The APX2180, APX4360, and DPX2250 have a switchable gain that is fixed at 45Hz. If you don’t want to boost the bass frequencies, set this control to “OFF.”
•The DPX1800 and DPX11500 have a variable-frequency bass boost control from 30Hz to 125Hz. They do not have a bass boost on/off switch, but a level control that goes from 0dB to 15dB.
CAUTION
This control can dramatically increase the power output level and could cause speaker damage if you over use it.

Matching subwoofer output to mid-range speakers
The DPX1800 and DPX11500 feature a polarity control switch for reversing the polarity of the output signal. This can be useful when matching the acoustic output of your subwoofers to the output of your mid-range speakers.
Connecting directly to a head unit
The amps provide connections directly to a head unit without a pre-amp output, such as a factory-installed head unit.
WARNING
When using the speaker (high-level) inputs, the black wire must be grounded at the radio. Failure to do so will result in noise and/or improper operation.
Care and maintenance
Cleaning the case
Use a soft, dry cloth to gently wipe dust and dirt from the unit.
Do not use benzene, thinner, car cleaner, or other cleaners. These substances may damage the unit or cause the paint to peel.
Servicing the unit
In the event that trouble arises, never open the case or disassemble the unit. The internal parts are not serviceable by the user. Opening any components will void the warranty.
CAUTION!
Changes or modifications to this product not approved by the manufacturer will void the warranty and will violate FCC approval.
