Going On-Line and Initialising… Once the app is opened and on-line (pressing the on-line button does this!) the amplifiers will be sending out identity messages and the app will recognise these and inform that an amp (or a number of amps) are available to connect. Press the orange button that appears to start the process. If grouping has been used, or previously configured using DeltaCore or AudioCore, a dialogue will appear asking do you want to use the most recent grouping session configuration found with a time and date of this session’s last set-up.

Once connected, all the amps appear on the default "All Devices" view, and real time metering should start. The amp’s icon on the left hand side of the virtual panel will show blue if the amplifier is running, grey in standby and red if there is a fault or the amp goes off line (stops communicating). The meter group for the outputs will also switch to show meters in greyscale if the power amp is in standby.
Page 6
The left hand icon on the amp's panel can be touched to reveal more info and adjust a selection of device properties including its name (touch to edit), standby switching, AES switching, bridging modes, and network output source selection (if audio network card is fitted). The buttons along the bottom of the screen allow quick access to see all device, and all absolute and relative groups.

Editing an Individual Device Touching an amplifier panel will open it up for editing: Mute buttons directly mute outputs (if a meter is outlined in red it is muted elsewhere by a group mute). The inputs are shown on the left of the screen, and the outputs are arranged in two banks of four on the right - main power amp DSP channels, then aux line level output DSP channels.

Individual bands may be edited by touching them in the table and directly moving slides or typing in values. On outputs, the crossover filters are accessed at the bottom of the table. Bypassed bands numbers are grey (like 3, 8 and 9 above). Touch the options top right on the window to reset all bands and access copy and paste.

Drag filter nodes to adjust frequency and gain. Pinch to adjust filter 'Q'. Touch the filter information above the graph to edit directly with sliders and numeric input. Touch options (top right) to reset a band, all bands and change what's shown - channel gain offset, Xovers included, phase response.

Touch routing matrix to access routing, channel ganging and channel naming. Full matrix mode can also be enabled independently for the power amplifier channels and aux channels. DeltaDirect Quick Start Guide Page 10...
Working With Groups Advanced grouping architecture can be directly configured from the app, and grouping information is stored in the amplifiers so can be retrieved when reconnecting. Touch the options in the top right of the devices screen to select "Configure Grouping": 32 absolute groups and 32 relative groups are available.
Page 12
Groups appear below the devices on the main screen - Absolute groups have an "A" top left, relative groups have an "R". Touch a group to see its members (dots above channels on devices that are part of the group). Controls for the group appear above the devices and can be directly edited. Muting a relative group will make the group button turn red.

You can still access individual device channels when using grouping, but channels in absolute groups will not allow EQ to be edited — they will show the EQ and detail which group they are part of so it’s quick to switch to that group and make changes as required.

This value will be the aggregated value of all group memberships' offsets. Channel meters outlined in red show that this channel is muted by a group. Copyright XTA Electronics Ltd. 2017 DeltaDirect Quick Start Guide Page 14...
