AMPSUB210
OWNER’S MANUAL
APPLICATIONS
SINGLE SOURCE SETUP
In this configuration the amplifier plays a single source such as home theater or home stereo. Connect the line out jacks from a stereo preamplifier or receiver to the Line 2 input jacks of your AMPSUB210. (Figure 10) Next connect your speakers to the terminals observing proper polarity (see “Speaker Terminals” Page 6).

The audio output of a local source, such as an MP3 Player, CD, television, computer, etc., is connected to the AMPSUB210 via the Line 1 inputs, and whenever the local source is active its signal will take priority over the distributed audio signal present at Line 2 . However, the distributed audio signal will still be present at the Line 2 input. In this circumstance the audio output of the local source will be heard via the AMPSUB210. Once the local source is turned off or muted, the AMPSUB210 will automatically switch back the distributed audio system as an audio source, assuming the local source remains inactive. The delay time of 4 seconds determines when switch back to the normal source will occur. This set up assumes all incoming signals are at line level and not at speaker level.

SETUP FOR MULTIPLE SOURCE
In the application shown in Figure 11, a distributed audio system is connected to the AMPSUB210 as a local zone amplifier via the Line 2 inputs. Normally the distributed audio system will be the audio source for the AMPSUB210. The distributed audio is then passed on to be used by additional zones or sub zones in the distributed system via the Line 2 outputs.
(Speaker Level Input)
Figure 12. Speaker Level with Multiple Sources
If the whole house distributed audio is only available as a speaker level signal you can connect it to the “Speaker In” connections and set the routing switch
to the “Line 2” position, the right hand position of the switch (Figure 12).The AMP SUB210 will no longer be able to pass the Whole House Distributed Audio to another zone via the Line 2 Output. If you have any questions regarding how to set this up, please call AudioSource® Tech support at 1.800.435.7115

Some home theater receivers have LFE Output. This bypasses the amplifier volume control, so use the receiver to set levels. Also set Variable Crossover 5 to full clockwise position (500Hz) and Subsonic Filter 4 slightly lower than your woofer’s F3 point, or between 9 and 12 o’clock if woofer specification is unavailable. See block diagram (figure 5) on page 5.
