English 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 with

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 gr

• Always use great care when attaching anything to a vehicle! Check clearances on all sides of the planned installation before drilling any holes or installing any screws. • Make sure the holes you plan to drill will not cut into the fuel tank, fuel lines, break lines (under the chassis) or electrical wiring. Don’t guess. Check first. Wiring precautions Read all wiring precautions. If you are not sure of the connections, contact your authorized Clarion Dealer. • Do not open the case. There are n

English Cables • Whenever possible, route power wire and signal wire on opposite sides of the vehicle. This prevents the signal cables from picking up electrically radiated noise. • Protect all wire from damage. Where a power wire passes through the fire wall or near exposed metal edges, protect the wire with a rubber or plastic grommet. Use wire loom where possible for further protection. • Extra cable can cause signal loss and act as an antenna for noise. Use only high- quality RCA cables that

DPX1800 and DPX11500 stackable configurations In this mode, the master amp’s front-panel controls apply to all amplifiers. For ex- ample, setting the crossover frequency on the master sets it on all slaves. This works for all front-panel controls. Multiple amplifiers can be daisy-chained together. For example, if you had six DPX1800s in a show car, you could control all of them from one master unit (and one remote). The following describes the configuration of the amplifiers: Master • Route inpu

English 6. Turn the volume back down slightly. 7. Slowly increase the gain control (clockwise). Stop when you hear a slight audio distortion. When the gain is properly set, you should achieve maximum undistorted output with the volume turned up all the way, not half way. If an oscilloscope is available, monitor the output of the amplifier with the scope, watching for clipping of the waveform. Set the gain so that only minor clipping occurs.
