INSTALLATION & OPERATION GUIDE

PREPARATION

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.
Adjust the transformer “tap” setting according to the level specified by the system designer.

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.

TERMINATION

Connect all wires.

INSTALLATION

Thread the bare end of the hanging or safety cable through the Fastlink wire joiner.
Attach the hanging or safety cable by securing it to or around the structure the speaker will hang from.
Thread the cable back through the Fastlink wire joiner and pull to tighten.

PLEASE NOTE:
It is imperative that the needed cable length is measured precisely. The tension cannot be loosened once pulled through the Fastlink.

Attach the carabiner through the eye end of the cable.
Attach the carabiner through one of the eye bolts on the back of the speaker.
Repeat with each cable. All four eye bolts should have a safety cable attached.
Angle the SD5 to fit into the ceiling and place the speaker driver side down into the tile.
Your speaker should now be securely installed.
