OWNER’S MANUAL

APPLICATIONS

NOTE: It should be noted that the AMP102/110 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.

STEREO SETUP

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 AMP102/110 (Figure 9). 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.

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 AMP102/110. Connect your mono speaker to the terminals of your AMP102/110 (see “Speaker Terminals” on Page 6). Leave the balance set to the center detent position.

SETUP FOR MULTIPLE SOURCE

In the application shown in Figure 10, a distributed audio system is connected to the AMP102/110 as a local zone amplifier via the Line 2 inputs. Normally the distributed audio system will be the audio source for the AMP102/110. 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.

Figure 10. Line Level with Multiple Sources

The audio output of a local source, such as an MP3 Player, CD, television, computer, etc., is connected to the AMP102/110 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 AMP102/110. Once the local source is turned off or muted, the AMP102/110 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.
