Upon powering up the unit, the device screen displays the current program number and program name assigned to the unit. If the program number ends with *, it means that no program is assigned, the last data before previous power down is recalled instead.

Channel menus
Channel linking
If the user presses one of the input or output Channel menu buttons, holds it down and presses any other channel menu button(s) in the input/output group, then the channels are linked together. The green menu LEDs for the linked channels are lit. Any modification of the data for the selected linked channel will be applied to the linked channels as well. To cancel linking, just press any other Channel menu key or the Exit key after releasing the held key.

When a channel(s) is selected, the front panel menu will display the settings. 


Use the Menu buttons to navigate menus, Cursor buttons to navigate parameters, enter to save to settings and exit to exit the menu. 

Input microphone gain (Only available for XD 4080-M and XD 8080-M models)

LEVEL: The level (or gain) ranges from 0dB to +45dB in 3dB steps. This level will only have an affect on the input channel when Mic input is selected from the system menu.

System Menu
The System menu allows the user to control and change parameters that are related to the system behaviour and general operation.
To access the system menu,

Make sure you are first in the main menu. (Press the Exit button to return to the main menu any time). Press the Enter key.


Preset Recall 

The XD has a built-in non-volatile memory that can store up to 30 different preset set-ups.
PRESET: This control selects which program to recall from the non-volatile memory. The program name is displayed to the right of the program #.
NAME: This shows the name of the program. This is read-only. The user has no access to them.


Preset Store

The XD has a built-in non-volatile memory that can store up to 30 different program (or preset) set-ups. A program can be stored using this menu. The old program with the same program number will be replaced. Once the program is stored in the flash memory, it can be recalled at a later time, even after power down.
PROG: This control selects which location in the non-volatile memory to save the program to.
NAME: A descriptive name of up to twelve characters can be assigned to each program.

FIR Taps Settings

1-4
Number of FIR Taps for each pair of output channels (i.e.. Output 1&2, output 3&4, output 5&6, output 7&8.) The sum of all taps cannot exceed 1500 and maximum taps per pair is 1200.(Parameters 5-8 are also available for XD series v5.xx and v6.xx. The FIR filters have been changed to dual channel structure in v7.xx.) For FIR filters, the higher the Taps the higher the slope in dB for the same frequency, or the lower the frequency the FIR can handle for the same slope. Generally speaking, higher frequencies require smaller number of Taps, and lower frequencies require a higher number of Taps.


Mic pre-amps

An optional microphone pre-amp can be added to the XD series. The user can select Line input or mic input from this menu. (Only available for XD4080-M and XD 8080-M models. Applies to Phantom power as well)
1-8
The user can choose between Line input or Mic input/ For Mic input, the input will receive a 30dB gain. Each input channel can be selected individually. (Input 5-8 only available for XD 8080 model. Applies to Phantom power as well.)

Phantom Power

The option microphone pre-amp also comes with Phantom power, which can also be enabled or disabled from this menu.
1-8
A 48V DC voltage can be supplied to external microphone when the Phantom power is enabled. Phantom power cannot be enabled individually for each input channel. All Mic input channels will automatically receive at 48V DC voltage. This will not affect Line input since they are disconnected physically.


Input and Output mode

The user can select analogue or digital signal for input and output channels. (I56 and I78 available forXD8080 revision B model only)If using AES/EBU, the XD accepts any sample rate on the inputs and will automatically up sample to its internal clock. The XD has a fixed output sample rate of 96kHz.

Copy Channels

Copy channels from the source to the target. When the source and targets are both inputs and outputs, all audio parameters will be copied. When the Source or the Target is an input while the other is an output, only the Level, Polarity, Delay, EQ, Crossover, and Channel name are copied.
SOURCE: This is the channel to be copied from.
TARGET: This is the channel to be copied to.

General Settings

FREQ MODE: This changes the frequency control mode for EQ and crossover filters. It can be 36 steps/octave or All frequencies (1Hz resolution).
DELAY UNIT: This sets the time unit for input and output delay to ms, ft, or m.

Ethernet Settings

IP ADR: A unique IP address should be assigned to each unit in the network.
GATEWAY: The gateway address of the network. Usually this should be the IP address of your router/switch/hub address.
SUBNET: This sets the subnet mask used by your network.


Communication Settings

NOTE: The user must power cycle the unit for this setting to take effect.
BAUD RATE: Sets the baud rate of the serial communication. XConsole uses a Baud rate of 115200. This should be left unchanged for most users.
DEVICE ID: This control assigns a device ID from 1 to 16 to the unit.
NETWORK ID: This control assigns a network ID from 0 to 60000 to the unit. The ID is used for future network expansion only. Please leave this at 0.

Security Lock and Unlock

PASSWORD: The password is four characters in length. The factory default of a new unit does not require a password. The device can be protected for unauthorized parameters and/or system abuse. The security settings can be controlled and stored in the device with the XConsole GUI only. When the correct password is entered in the device, all the locks are disabled. After re-entering the password or power cycling the device, the locks are automatically enabled again.

Factory Settings

CURRENT: This resets all the current parameters back to factory default settings only, while stored presets and system settings stay untouched.

ISO Settings

This internal system optimizer reduces ground floor noise if no signal is present. If unwanted noise gate effects are audible at low sound levels, it can be switched to bypass mode.


Info

This menu displays the device name, firmware version and security code. When no password is set, the factory default code is 11110000. When another combination of characters is displayed, a password is set in the device and certain functions are disabled for the user to modify.
