8. H8 DSP INSTALLATION GUIDE USING A PC.

To configure the H8 DSP inputs, analog (PRE) outputs, equalizations and time delays, the processor must be
connected to a PC after calibrating the input levels. At that point, you need to have in mind the system you want to
develop, since from this moment if you want to change any of the settings, you will have to go through the guided
procedure all over again.
More specifically the guided procedure will request:
- Which kind of specialization the main inputs channels use. The guided procedure changes according to your
selection.
- Which auxiliary inputs will be used (e.g. AUX and OPTICAL IN).
- Which kind of signals will be allocated to the different outputs (e.g. Front Left, Center or Subwoofer etc.).
- Which speakers you are using for your system (e.g. 2-way Front, Front / Rear, Sub etc.).
- If the system features passive crossovers to manage speaker groups (e.g. 2-way system with active mid-low).
During this procedure, you should disconnect the H8 DSP output RCA plugs to the amplifiers.

SELECTING THE MASTER (FRONT / REAR) INPUTS AND OUTPUTS - TARGET MODE

1.
Connect the head unit speaker outputs to the H8 DSP high-level input
Before turning on the system, make sure the amplifier's RCA plugs are disconnected from the H8 DSP to avoid
speaker damage during the calibration procedure
The input calibration procedure must be performed with the ignition turned on. In this case, the car voltage is
about 14.0 volts. The head unit will provide an undistorted output signal at higher volume.
2.
Make sure that the IN Level knobs for the inputs used (L / R Front, L / R Rear, Aux IN L-R) are set to minimum
sensitivity as in the figure (position -).
3. Turn on the H8 DSP and connect the USB cable to a PC. Start H8 DSP software by clicking the icon previously
created on the PC desktop.
The first window is the start page where you need to choose among three operational modes:
Select the CONNECT start mode on the drop-down menu.
