Vanguard Dynamics IOS Series Owner's Manual

WIRING
1. Attach the speaker cables to the speaker cable terminals located on the back of the IOS
speaker.
2. Connect the speaker cable while ensuring proper polarity with the amplifier, + to + (red)
and – to – (black).
3. Also ensure that the right channel of the amplifier is connected to the right speaker and
left channel to the left speaker.
PLACEMENT
Outdoor Installations
1. When mounting the IOS speakers outdoors, the eaves of the roof provide an ideal
location as they reduce the exposure of constant direct sunlight and precipitation.
2. If installing speakers on a boat, the wheelhouse provides the best location for
the same reasons.
Indoor Installations
1. When placing the IOS speakers on a wall or bookshelf, we recommend that they are mounted at ear level or
slightly higher.
2. The usual listening area should be no closer to the speakers than the distance between the speakers themselves.
MOUNTING
1. The IOS speaker is supplied with a U shaped wall mounting bracket that can be installed vertically or horizontally.
2. Use screws, bolts or anchors (not included) that are capable of supporting the weight of the speaker to mount the bracket.
3. Once the wall mounting bracket is securely fastened, insert thumbscrews through bracket into the speaker.
4. Rotate the speaker to desired position and tighten the thumbscrews.
5. There are two M6 inserts located on the back of the speaker for other types of mounting brackets.
6. Make sure to select a bracket capable of supporting the weight of the speaker.

listening area.
