Power ON/OFF Management

- The On/Off function of electrical components cause pulses that can be

amplified by the system’s amplifier and cause “POP” noises. The HDSP firmware and software are designed
to prevent this. The Power On/Off menu lets you modify the On /Off delays to best suit your system’s
needs. From the factory, the HDSP will turn on with only power and ground by pushing the Volume
knob of the Dashboard remote. One of the first things you should do is what system you will use for
On/Off triggers. A couple of notes are needed for Power by Audio in and for the timing of the amplifier
turn-on from the HDSP. For the Power On/Off by Audio In you will want a short delay for On, but a long
delay for Off. The lower section is to control the amplifier turn-on from the White +12v out. Power off
delays are normally not used because you want the amp to turn off fast so it cannot amplify the turn-off
pulse. This is often a problem because most processors that have turn-on wires must turn off before
the amp trigger can turn off. The HDSP lets you set a delay for the amp turn-on and delay, or no delay,
for amp turn-off. The third setting (Off Power Enable Delay) lets you set a delay time that keeps the
HDSP on until after the amp has had time to shut off completely so there will be no turn-off noise. 

Reset

- Allows you to undo changes you have made to the system. You can choose to return to the

default settings of the desired parameter or you can simply return to the last saved value to undo only
the last adjustment.
