STEREO TRI-AMP MODE:
In this mode, the bandpass feature on the front
channels is activated, configuring the 500/5's
crossover sections to true three-way operation.
This allows the independent powering of tweeters,
midwoofers and subwoofer(s) in the system and
gives extensive control over level matching and
crossover parameters. Left and right tweeter
channels (25W x 2 @ 3 - 4 Ω per channel), high-
pass filtered. Left and right midwoofer channels
(100W x 2 @ 1.5 - 4 Ω per channel), bandpass
filtered. One mono subwoofer channel (250W x 1
@ 1.5 - 4 Ω), low-pass filtered.
Input connection options for the Tri-amp Stereo
mode are as follows:
A) Single pair of inputs connected to the rear
inputs of the 500/5. In this mode, the user has no
adjustability of subwoofer level from the front of the
vehicle. See diagram A below.
B) Two pairs of inputs connected to the rear and
subwoofer inputs of the 500/5 (a source unit or
processor with front and rear pairs of outputs is
required). In this mode, the user has the ability to
fade or control the level of the subwoofer channel
relative to the mid and high-frequency channels. See
diagram B below.
