4. Using Audio-over-USB decoder
To install these loudspeakers so that a PC will
recognise it as an audio output device follow these
steps:
Step 1: Connect USB to the decoder.
If using a Techconnect connectivity faceplate USB
from the PC will plug into the front of the USB-B
module. Then use the short USB cable included to
connect from the rear of the USB-B module into the
decoder (2).
The decoder has a USB-A connector which (1) is
connected to an interactive whiteboard.
Step 2: Connect audio output (green connector)
on the decoder to the input on the amplifier as
shown.
NOTE: The USB decodes outputs line-level
signal which can be input into any low
impedance amplifier
Step 3: Connect power to power input
(black connector) on decoder.
NOTE: Power is ONLY required if the USB
signal continues on to another device such as
an interactive whiteboard. If no other device is
connected then the power carried on the USB
input cable is sufficient to power the decoder.
If using a Techconnect amplifier plug the power
supply into the decoder (1), use power patch cable
provided to connect the decoder power output
connector to the Techconnect Amplifier module
power input (2).
