• Remove the speaker from the box and packaging.

• Remove the ceiling tile from the grid where you wish to install the speaker. NOTE: If you are installing the speaker into a

2’ x 4’ ceiling tile space, you will need to cut the tile to ﬁt the speaker and use a common ceiling t-rail.

• Pull all needed wires.

• Set the 70 volt/8 ohm tap selector*: Use the transformer switch to match the input voltage speciﬁed by the system

designer. To do this you may need to slide the switch from 70 volt (factory default setting) to 25 volt or, in some cases, to

bypass directly. This switch is located next to the power level selector switch. Both 70 volt and 25 volt settings are

available, as well as a bypass to the 8 ohm driver**.

• Adjust the transformer “tap” setting according to the level speciﬁed by the system designer. The ESSENTIALS and PRIVACY

speakers are set at a factory default 2 watt tap setting prior to shipping. The APPLAUSE speakers are set at factory default

7.5 watt tap setting prior to shipping***.

*Use in conjunction with ampliﬁer output/rating requirements.

**Do not feed 70 volt or 25 volt signal into the speakers when the 8 ohm bypass mode has been selected. This will permanently

damage the speaker.

***Do not exceed the maximum power rating of the speaker. The maximum power rating for each speaker is as follows:

ESSENTIALS = 8 watts, PRIVACY = 4 watts, APPLAUSE = 30 watts
