volume, moving it down reduces it. Altering the value will change the volume on that channel only. Click and hold the

left mouse button down on the slider and drag the mouse forward or backward to move the slider upward or downward

respectively. The new volume value is sent to the BoomBox once the mouse button is released.

The volume control also accepts a value that is typed in. A single left click on the control will highlight the volume

controls text value and typing a new value will overwrite the current text. Once the required value is entered, press the

Enter key to complete the process and accept the new value. If a valid number is entered, the control will change to the

newly entered number or as close to it as the control's range allows. The control will revert back to its previous value if

an invalid number is entered. If the Enter key is not pressed after entering a new value and a different control is

selected, the control that was being edited will revert to its previous value.

Each individual output has its own local set of controls (see Figure 5). At the top is the

channel select. This allows selection of which of the two possible audio streams to use for

setup. The active channel button will show green, and the inactive channel button show

grey. One or the other of the channel select buttons will always be active. To select the

other audio stream, simply click the inactive channel select button.

There are no restrictions on how many outputs on a given unit can use a particular audio

stream or in which order the streams are allocated to the outputs. The channel selection

can also be changed on the fly.
