Connections
Installation
Locate the IW30B 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 connection on the IW30B. The speaker connections are via screw terminals on a Euroblock, which can be removed for easy access whilst making connections.
Important: Ensure that the load is no lower than 4 Ω for each output.
(e.g. 2 x 4 Ω speakers… or… 2 pairs of 8 Ω speakers wired in parallel)
Ensure that the speakers can handle 15W from each output.
If the IW30B is to be used with a wired audio line level input (instead of Bluetooth), connect this to the Euroblock terminals labelled “AUX IN” as shown on the Connections diagram above.
Left positive connection (Lef t+) should be connected to “L”
Right positive connection (Right+) should be co nnected to “R”
Both negative connections (Left- and Right) should be connected to “G”
(G is the terminal for Ground connection – common for both Left and Right signals)
Likewise, the Bluetooth or Aux input can be relayed to further IW30B or other amplifiers by connecting a line level output from the Euroblock terminals labelled “AUX OUT”
AUX IN and AUX OUT connections should be made using shielded stereo audio cable and not speaker cable.

Operation
When powered up, the IW30B will be open for Bluetooth pairing.
(a small LED will flash inside the housing)
Ensure that only the first IW30B in an AUX OUT-IN daisy chain is powered up initially.
This will ensure that all of the amps in the daisy chain receive the same audio.
Search available Bluetooth devices on your smart phone or other sending device for a device with Bluetooth ID “ IW30B-**** ” (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 smart phone or other sending device and play a track to check the sound through the speakers
Power down the IW30B when not in use and isolate from the mains if not used for long periods of time.
