SAFETY SYMBOL AND MESSAGE CONVENTIONS

CAUTION
RISK OF ELECTRIC SHOCK  – DO NOT OPEN

This symbol indicates that dangerous voltage constituting a risk of electric
shock is present within this unit

This symbol indicates that there are important operating and maintenance
instructions in the literature accompanying this unit.

Warning

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, allow unit to dry out and have checked by qualified personnel before further use. Avoid impact, extreme pressure or heavy vibration to the case. No user serviceable parts inside – Do not open the case – refer all servicing to qualified service personnel.

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 Bluetooth connection range of the sending device

Cleaning

• Use a soft cloth with a neutral detergent to clean the housing as required
• Use a vacuum cleaner to clear apertures and controls of any dust or debris build-ups
• Do not use solvents for cleaning the unit

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 4Ω for each output.
(i.e. 2 x 4Ω speakers… or… 2 pairs of 8Ω 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 (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 labelled “AUX OUT”

Note : 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)

If several IW amplifiers are set up in an AUX OUT-IN daisy chain, ensure that the first amplifier in the chain is powered up initially. This will ensure that it is the one that receives the line input or is paired to via Bluetooth and that all of the amplifiers in the 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 the IW30B (for Android devices, it is possible to rename it)

Note : Once pairing is successfully completed, no other devices can pair with the IW30B until it has been powered off and then on again.

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 it is not being used for long periods of time.
