Safety

• Check for correct mains voltage before connecting the power adaptor
• Use only the power adaptor provided or an identical replacement

Placement

• The IW30B can be installed in a ceiling or stud wall to power flush or surface mount speakers
• The IW30B can also be surface mounted if necessary
• Ensure adequate ventilation for cooling and keep away from combustible material or moisture
• Ensure that the IW30B is within the Bluetooth connection range of the sending device

Cleaning

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 for each output. (e.g. 2 x 4 speakers… or… 2 pairs of 8 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 labeled “AUX IN” as shown on the Connections diagram above.

Left positive connection (Left+) should be connected to “L”
Right positive connection (Right+) should be connected 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 labeled “AUX OUT”

AUX IN and AUX OUT connections should be made using the shielded stereo audio cable and not the 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 smartphone 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 smartphone 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.
