Diamond Audio Technology D5 1200.1 Kullanıcı El Kitabı

GAIN

This control matches the output voltage of the source unit or processor to the

amplifier inputs. Rotating this control to the "MIN" mark (counterclockwise)

configures your D5 amplifier to accept input voltages as high as 5V RMS. This

control should be set as low as possible. The basic procedure for setting input

gains is as follows:

Adjust all amplifier gain controls to just above the minimum setting

(fully counterclockwise).

Using the highest quality source (usually CD) play some music and

slowly turn up the source unit until you can hear distortion. Now

turndown the volume until the distortion stops. This is your maximum

source unit level.

Turn up the amplifier gain until audible distortion starts. Turn down

the gain to the point JUST BELOW the start of the distortion.

Repeat step 3 for all amplifiers in your system.

SUBSONIC FREQUENCY

Turning this control sets the Subsonic filter point from 15Hz (fully

counterclockwise) to 40Hz (fully clockwise).

PHASE IN/OUT

Pushing this button "IN" engages the Phase switch, putting the amp 180

degrees out of phase. Pushing this button "OUT" keeps the amp in phase. In

some vehicles this can help with the timing and overall response of your

system. If your woofers are not in phase with the rest of the system it can

cause bad timing and gaps in the pass band. Unlike some Class "D" amplifiers,

this option does not allow you to use two D5 Class "D's" as one channel.

Trying this can cause damage to your amplifiers and woofers.

LOWPASS FREQUENCY

Turning this control sets the Lowpass crossover point from 50Hz (fully

counterclockwise) to 250Hz (fully clockwise).
