Output Channels

6.2. Setting Output Parameters

Signal processing for each output channel is programmed independently via the separate Output menu associated with each channel. The signal processing parameters are described below in menu order.

To access the Output menu pages for a particular channel

Press its yellow MENU ACCESS button (1 – 8) to switch to its menu.

Press the button repeatedly to step through the pages in turn. Note that, after the last page, the next button press will cycle the menu back to the first page.

To skip across to the same parameter on another output, press its MENU ACCESS button.

6.2.2Naming the Output Channel (Page 1)

Each output channel can be allocated a name up to 8 characters long, which will be shown in the first page of the menu for easy reference. The default names are Output 1, Output 2, etc. Names are retained after power down and are included in stored settings.

To enter a name

User defined channel name

1Turn the left-hand knob clockwise to access the Output Name menu page.

2Use the centre knob to move the cursor right or left, and the right-hand knob to select the letter, number or symbol.

3On completion, turn the left-hand knob anti-clockwise to go back to the main page. The new name is now shown to the left of the menu page.

6.2.3Routing (Page 2)

Each output of the DN9848 can be acquired from a single input, a pair of outputs or all outputs. For paired outputs, the source inputs are attenuated by 6dB prior to summing and the ratio of the two signals used is adjustable. When all outputs are

combined, the source inputs are attenuated by 12dB prior to summing in equal proportion. (See Section 6.1 for Technical Overview).

For easy access and reference purposes, the routing is selected in the first menu page as shown opposite.

To set the routing for the output

1Turn the centre knob to select the required source from the following sequence of choices: A, B, C, D, A+B, C+D, All.

The ratio of paired outputs is adjustable.

2If you select A+B or C+D, use the right-hand knob to set the ratio for the signals, i.e. A:B or C:D, respectively.

Important! Delays for the summed channels must be set to the same value.
