Safety
Placement: To prevent the risk of fire or electric shock, do not expose any components to rain or moisture. If liquids are spilled on the casing, stop using immediately, allowunit to dry out and have checked by qualified personnel before further use. Avoid impact, extreme pressure or heavy vibration to the case.
Cleaning
To clean the IW415B, use a soft, dry cloth. Do not use any liquid or abrasive cleaners.
Connections
To install the IW415B:
- Locate the IW415B in the ceiling, wall or on the surface required. Tabs at each end of the housing can be used for securing with screws.
- Connect speakers using the supplied wires or equivalent by connecting + and – on the speaker to the relevant connections on the IW415B.
- There are 4 speaker outputs in total, which are 2 x Left and 2 x Right.
- The speaker connections are via screw terminals on 2 Euroblocks, each with stereo speaker outputs (Left + Right on each block). These Euroblocks can be removed for easy access whilst making connections.
Important:
- Ensure that the load is no lower than 4 ohms for each output. For example, use either 4 x 4-ohm speakers or 4 pairs of 8-ohm speakers wired in parallel.
- Ensure that the connected speakers can handle 15W from each output.
If the IW415B is to be used with a wired audio line level input (instead of Bluetooth), connect this to the 3.5mm stereo jack input labelled AUX IN as shown on the Connections diagram above. AUX IN connection should be made using shielded stereo audio cable and not a speaker cable. In either case, Left & Right audio is fed simultaneously to 2 x Left and 2 x Right outputs. It is not possible to choose Bluetooth for one side and AUX input for the other.
Operation
When powered up, the IW415B will be open for Bluetooth pairing. A small LED will flash inside the housing.
To pair and connect with a Bluetooth device:
- Search available Bluetooth devices on your smartphone or other sending device for a device with Bluetooth ID IW415B-**** (where is a unique ID number for each unit).
- Select to pair and connect with this ID (rename if required on Android).
- When paired and connected, set the volume low on the smartphone or other sending device and play a track to check the sound through the speakers. Increase volume as required from the sending device or Aux input source.
