SYSTEM CONFIGURATIONS
The XD700/5v2 is a very flexible amplifier, 
well-suited for a multitude of system 
configurations. In this section, the most likely 
configurations for a system with a single 
XD700/5v2 are explained in detail.
Once you have selected your desired 
configuration, you can use the amplifier panel 
drawing on pages 18 & 19 to mark the required 
switch positions for easy reference.
BI-AMPLIFIED SYSTEMS
Bi-amplified systems are defined as systems 
in which separate amplifier channels drive low-
frequency (LF) and high-frequency (HF) speakers 
and are separately filtered to send appropriate 
frequency ranges to each speaker system.
The most common application of 
bi-amplification in mobile audio is to drive a 
subwoofer system from one or more amplifiers or 
channels and component speakers from separate 
amplifiers or channels.
The XD700/5v2 can be configured to drive a 
bi-amplified system by itself.
 
Bi-Amplified System with one XD700/5v2
In this configuration, the Subwoofer Channel 
of the XD700/5v2 will drive a subwoofer system 
with low-pass filtering. The Main Channels (1&2, 
3&4) will drive component speakers in stereo 
with high-pass filtering. 
Crossover Setup for Bi-Amplified System  
with one XD700/5v2:
Once the input sections have been configured 
appropriately (see page 6), go to the “SUB CH.” 
control section and select “12dB” or 
“24dB” 
(low-pass) on the “LP Filter Mode” switch and 
an appropriate “Filter Freq.” (80 Hz is a good 
starting point). The “12dB” setting engages a 
shallow filter slope that gradually attenuates 
frequencies above the selected “Filter Freq.” 
setting. The “24dB” setting engages a sharper 
filter slope that more aggressively attenuates 
frequencies above the selected “Filter Freq.” 
setting. Neither setting is “better”, but in general, 
the shallower “12dB” setting is more desirable for 
a subwoofer having to fire from a trunk into the 
cabin of a sedan or coupe. The sharper “24dB” 
setting is typically better in a hatchback, SUV or 
wagon application. Experiment to find the slope 
setting that results in the smoothest subwoofer to 
midbass transition.
Next, turn your attention to the “CH 1 & 2 
Controls and select “x1” (high-pass) on the “HP 
Filter Mode” switch and select an appropriate 
Filter Freq.” (again, 80 Hz is a good starting 
point). The  “x1” setting means that the Filter 
Freq. indicated on the dial is exactly what you are 
selecting.  (In the “x10” mode, the actual Filter 
Frequency is ten times higher than the indicated 
value. This setting is generally not used in 
bi-amplified systems.)
Finally, turn your attention to the “CH 3 & 4 
Controls and select “HP” (high-pass) on the “Filter 
Mode
” switch and select an appropriate “Filter 
Freq.
” (again, 80 Hz is a good starting point).
Tri-Amplified Systems with one XD700/5v2
The XD700/5v2’s 3-way crossover capability 
allows you to create true, tri-amplified systems by 
selecting the appropriate settings described below.
In a tri-amplified configuration, the 
Subwoofer Channel of the XD700/5v2 will 
drive a subwoofer system, in mono, with 
low-pass filtering. Channels 3 & 4 will drive 
component woofers (or mid-range speakers) in 
stereo with bandpass filtering (both a high-pass 
and a low-pass filter applied). Channels 1 & 2 
will drive high-frequency speakers (tweeters, 
typically), in stereo, with high-pass filtering.
To operate a single XD700/5v2 in Tri-Amplified 
mode, set the “Input Mode” switch in “2 Ch.” 
mode, and apply a single set of stereo inputs to the 
Ch. 1 & 2 Inputs only!
