DB Drive APM 250.4D Bedienungsanleitung

Due to continuous improvement of the product the Specifications are subject to change without notice.

APM 250.4D, AMP 300.2D

Low Impedance Stability

APM 250.4D - 2 Ohm Stereo (4 Channel)

APM 300.2D- 2 Ohm Stereo ( 2 Channel)

Bass Boost

For added low frequency performance the amplifiers are equipped with a variable 0dB-12dB

bass boost @ 45Hz

Conformal Coating

The internal components of APM amplfiers have been coated with a marine grade

protective coating that shield them from the elements. This asures optimal performance

in even the most rigourous enviroments. Although the amplifier is protected agaist the

elements , it does not make the amplfier 100% water resistant. Special care must be

taken when chosing a mounting location to asure that it does not end sumerged under

water.

The “APM Marine” amplifiers include built-in variable crossovers. The APM 250.4D offers

an independent 12dB per octave High Pass and Low Pass X-Over on channels 1&2 and

a Selectable 12dB or 24dB per octave X-over on channels 3&4. The APM 300.2 offers a

12dB per octave slope when set to either Low or high pass settings.

Variable Crossover

Due to the smaller foot print of the amplifier, external fusing is required.

The APM 250.4D amplier is equippedwith a variable crossover network thatallows you to select the

crossover mode (Highpass—Full Range) and desired crossover point for channels 1 and 2. Channels 3

and 4 allow you to select between a Highpass 12db slope, a 12db Stereo Lowpass / Bandpass slope and a

For example if you wish to drive a pair of subwoofers on channels 3 and 4 in the br acuoy,edomdegdi n

select the LP/BP mono switch setting on the ampli er to lter out the high frequencies with a 24db

slope. You will then need to adjust the Lowpass control to the desired frequency setting (make sure to

have the Highpass control set to 15Hz so that the Bandpass lter does not engage)This will only send

low frequencies to your subwoofers. If you wish to use the Bandpass crossover -xehttestsumuoyretl

over switch to LP/BPstereo. Once the LP/BP stereo switch setting is selected youwill use both the

Lowpass and Highpass controls to lter out the unwanted low and high frequencies to create the

desired Bandpass ehtesuoT)4dna3slennahcylnonoelbaliavasirevossorcssapdnaBehT(.retl
