INSTALLATION
1. Install back box to wall (e.g. included iWB 1)
2. Install power supply. The iWA 1 is designed to be operated at 24V dc, but will accept from 24 to 30V dc.
A regulated power supply is highly recommended. If using a very long cable, between the power
supply and the iWA 1 consider a higher voltage power supply (e.g. 30V) to allow for the resulting
voltage drop.
3. Connect power supply to the 24V dc terminals taking care to observe the correct polarity.
4. Connect the audio source to the audio input terminals
5. Connect the speakers (minimum impedance 4 ohms) to the speaker left and right terminals respectively.
If a metal back box is used, take care that no connections come in to contact with it.
OPERATION
1. Push the volume knob once to turn on the iWA 1 from MUTE.
2. Rotate the volume knob on the control panel clockwise; the volume will increase and the indicator
light will continually light up. The indicator light around the edge of the volume knob will flash when
maximum is reached.
3. If an external Media player is connected to the front Aux IN socket (using a 3.5 mm stereo plug), the
external Media Player will be directly selected and the rear audio input will be cut out. It is
recommended to mute the volume before plugging/unplugging the external Media Player cable.
4. Push the volume knob once again to put the iWA 1 into MUTE mode. The iWA 1 has no OFF switch.
Please push the volume knob to MUTE it if not use.
5. The volume level is stored when the DC supply is removed; it will be restored when the power is
resumed.
