Daisy Chain
If you are using 2xDB1.8 in a daisy chain configuration you must switch the master/slave
control on each to choose which unit will be in control. Connect the two together using an
appropriate 4 pin RJ45 style cable. Plug into the Master Output terminal FROM the master
and Slave Input terminal TO the Slave. Please make this change BEFORE powering the units
up. Failure to get this correct before power up for strapped operations can result in damage
to the processor which is NOT covered under warranty.
Setup
Once everything is perfect and you’re ready to go set the gain to minimum and put the
fuses in and apply power to the remote terminal. We recommend also setting the gain on
the remote to zero as this control is a gain control with 18db of range.
Begin with the bass boost at 0db, the phase shift at 0 degrees and the subsonic set to a
suitable value to save power below the real output floor of your woofer. Dial in the low pass
filter (all these are 12db/octave) and ensure your source unit or processor is also
appropriately set to zeroed.
We recommend a conservative gain structure, leaving headroom in the remote control to
allow real world tweaking of the level to suit the recording from the cockpit. We don’t
recommend that you gain the amp up to the maximum level for the most dense music you
