Installation
The speaker is supplied with a mounting bracket that can be left on in case of permanent
fixing, or removed altogether depending on personal choice.
Connect the 3.5mm mono lead supplied to the extension speaker socket of your
equipment and the 4mm black and red plugs into the corresponding red and black sockets
on the rear of the speaker.
Connect the fused DC power lead supplied to a power supply capable of providing 12 -
18VDC @ 300mA. (The centre pin of the 2.1mm power connector is positive and the lead
with the white stripe is positive), or use a suitable mains plug-in 12V DC power supply
(300mA).

Speaker Operation
Once installed and connected, apply power to both the audio source and the speaker.
Press the power/bypass switch located in the speaker front grill. When power is applied to
the speaker, the LED will flash and turn red or orange depending on whether 4 or 8 levels
of noise cancelling have been selected. The power button switches the module on and off.
When the module is switched off, the audio bypasses the module, so the circuit will
behave as if the module isn’t present and the unit becomes a passive extension speaker.
Note:
If the power is on and the DSP is switched off, the audio still passes through the
DSP, but without any signal processing.
