APPLICATIONS

NOTE: It should be noted that the AMP210/310 is rated to operate into a minimum 8-ohm bridged load. Therefore, if you are using more than a single

8-ohm loudspeaker in bridged mode you should consider using an impedance matching speaker selector, such as the Phoenix Gold® Innovative Home ISM4, ISM6 or ISM8, or possibly using an impedance matching volume control, such as the Phoenix Gold® Innovative Home VMT100 available at your favorite DIY store or electrical supply. The choice of a volume control would allow you the additional flexibility of being able to attenuate the volume whenever necessary.

In this configuration, the mode switch is set to “Stereo”. Connect the line out jacks from a stereo preamplifier or source to the Line 2 input jacks of your AMP210/310 (Figure 11). Next connect your speakers to the terminals marked “Speaker A” observing proper polarity (see “Speaker Terminals” Page 6). Connect a second (optional) pair of speakers to the terminals marked “Speaker B”. Select the “A” speakers using the front panel speaker selection buttons.

The audio output of a local source, such as an MP3 Player, CD, television, computer, etc., is connected to the AMP210/310 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 AMP210/310. Once the local source is turned off or muted, the AMP210/310 will automatically switch back the distributed audio system as an audio source, assuming the local source remains inactive. The delay time adjustment 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.

MONO SETUP

In this configuration, the mode switch is set to “Bridged”. Connect the Left line out from a preamplifier to the left Line 2 inputs of your AMP210/310. Connect your mono speaker to the terminals of your AMP210/310 (see “Speaker Terminals” on Page 6). Use the left “Master Level” control on the rear panel to adjust the volume. Leave the balance set to the center detent position.

SETUP FOR MULTIPLE SOURCE

In the application shown in Figure 12, a distributed audio system is connected to the AMP210/310 as a local zone amplifier via the Line 2 inputs. Normally the distributed audio system will be the audio source for the AMP210/310. 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.

If the whole house distributed audio was only available as a speaker level signal you could 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 13).The AMP 210/310 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 or 503.286.9300.
