NM 84 LCD Edit Pages

Each Edit page name appears in the upper left corner of

the LCD display. Seventeen (17) pages are found:

   8 pages for Inputs, named IN 1 through IN 8 (one page for

each of the Mic Inputs)

   4 pages for Monitor Outs, named Monitor 1 through

Monitor 4 (one page for each Monitor Out)

   2 pages for Network Transmit, (NetTx A/B and NetTx

C/D) for selecting 20- or 24-bit Format audio transmission

over the network and to select which of four CobraNet

Bundle(s) to transmit onto.

There is one Edit page each for the following:

   Mem page for Memory Storing, Recalling and setting the

Memory Recall Port Transmit (MRP Tx) and MRP Receive

(MRP Rx) channels.

   Serial page for setting the RS-232 Baud rate and Transmit

(232 Tx) and Receive (232 Rx) channels.

   Config page for setting the IP Address and Device Name.

The top row of text on each Edit page contains the

parameter names. Their current settings appear below the

name. To edit a parameter’s setting, place the underline cursor

under the value that appears below the parameter name. Use

the lower Previous (<) and Next (>) cursor buttons to move

the cursor. Edit the parameter value by rotating the Data

Wheel. Clockwise rotation increases the value, counterclock-

wise rotation decreases the value. To quickly maximize or

minimize a parameter’s value, hold down the EXE button and

press Next Page (>>) or Next Cursor (>) buttons, respectively.

Copy, Paste and Load “X” fields are found in several Edit

pages. Move the cursor under the Copy field, rotate the

DATA wheel to select the desired command, then press the

EXE button to execute the command.

Use Copy to place the current Edit page contents in a

clipboard. Navigate to the Edit page where you want to paste

these settings and execute a Paste by pressing the EXE

button. [For convenience, the Copy field is automatically

changed to Paste after executing the Copy command.]

Load “X” allows the contents stored in Memory “X’s”

corresponding Edit page to be pasted into the current Edit

page. “X” can be changed to any of the 16 Memories, 1

through 16, using the DATA wheel; Load 1, Load 2, Load 3,

etc. This is an easy way to copy a single Edit page’s contents

from a stored Memory into the current page.

Input Edit Pages – IN 1 through IN 8

Each of the eight Input Edit pages sets up one of the Mic

Inputs. Two modes are possible for each Input, Mic or Line

(see LCD screen shot below).

The only differences between Mic mode and Line mode

are that Mic offers selection of +48 volts for phantom power

and the Gain selection differs. Mic mode Gain 15, 30,

45 and 60 dB settings while Line mode 10 dB and -5

dB gain settings. All other settings and ranges are identical.
