1. Introduction

Welcome!
Thank you for purchasing the DP48 Personal Monitor Mixer!

The DP48 unit is housed in a compact format suitable for mounting on microphone stands with the optional DP48MB mounting bracket system (sold separately).

All user controls are laid out for ease of use on the top panel, while all primary connectors are on the DP48’s rear panel.

The DP48 Dual Monitoring Mixer uses a low-latency, floating-point audio engine to provide an excellent stage and IEM (In-Ear Monitoring) sound with independent mixes for one or two users. The mixer can be operated in two different modes: SINGLE (one mix for one musician, with dual MY GROUP knobs available) and DUAL (separate mixes for two musicians).

The DP48’s AES50 connection provides 48 individual input channels at 48 kHz/24-bit resolution that can freely be mixed into 12 stereo groups. All 12 stereo groups feature semi-parametric 3-band EQ, compression, and reverb send. Mixes A and B each have their own EQ processing and an adjustable brick wall limiter to prevent excessive levels on the phone’s outputs.

DP48 also includes an automatic configuration function to simplify Channel-to- Group assignments when setting up mixes. Now, instead of manually setting up your Groups from scratch, DP48 can automatically evaluate the AES50 datastream and assign to Groups 1-12 all channels that share specific common features, such as channel colors or channel names. This auto-configuration function thereby allows the engineer to easily distribute his mixed structure throughout the connected IEM (In-Ear Monitoring) world.

4. Operation

Controls and indicators
For any operation, the function buttons usable for that operation will illuminate with a white backlight to show the buttons are active. For example, the LOW/MID/HIGH equalizer or COMP (compressor) buttons will illuminate when either a GROUPS 1-12 or MIX A/MIX B button is pressed.

Any selection can be toggled on/off by pressing the button repeatedly. When a specific function button is not available, please consider switching other active functions off first.

In some menus, the REVERB(<<) and PAN(>>) buttons are used to navigate between pages.

Choosing a mixed-mode
As a first step, you should choose a mixed-mode to suit your needs. For example, are you sharing the same DP48 mixer with another musician, or will you be the only musician using the mixer?
Each of the mix modes–SINGLE and DUAL–define what parameters are in common for both MIX A and MIX B:
• SINGLE mode only uses MIX A, but this mode also allows you to assign the left and right MY GROUP knobs to different Groups for extra control on the fly. Use shortcut “MIX A” [“MIX B”] + any of the GROUPS 1-12 number buttons to assign the left [right] group to the MY GROUP knobs.
• DUAL mode permits the same Groups to have different level and panorama settings for MIX A and MIX B
NOTE: For both MIX A and MIX B, the underlying channel-to-Group configurations remain the same.

To choose a mixed-mode

1. Press the SETUP button to access the SETUP screens.
2. Select page 1/8 by rotating the SELECT/EDIT push encoder or pressing the REVERB(<<) and PAN(>>) buttons.

  • Compressor 0% and Reverb Sendoff
  • All groups mixed to both Mix A and B
  • MY GROUP is not assigned yet

Auto-Configuration of Channels and Groups
DP48’s “ASSIGN BY” macro features automatic mapping of incoming AES50 channels to Groups. This mapping can be done by using channel color and channel name information, as set up by the FOH or monitor engineer at the mixing board.
NOTE: The SETUP/ASSIGN BY macros only map channels once, according to the AES50 channel colors/names at the time the function is launched. The function does NOT automatically update, so if the engineer subsequently changes his setup, you will need to re-launch the AutoConfig function to capture the new configuration to your DP48. You can also change the automatic mappings manually at any time if you are not satisfied with the results.
To auto-configure the channel-group assignments, press the SETUP button and choose your preferred ASSIGN BY function on the SETUP screen:

• ASSIGN BY NAME uses channel name information in the AES50 datastream to automatically map input channels to DP48
  Groups, including the following details:

  • Confirm/cancel that channels will be assigned to Groups 1-12 by channel name
  • Function clears all previous Group channel assignments
  • Channels with specific leading characters such as – ` * ( ) ,. / [ ] < > will be mixed to their assigned Group with 0 dB level and panned to center · Input channels with different leading characters will not be assigned automatically
  • Channels can later be re-assigned manually by pressing the ASSIGN button

• ASSIGN BY COLOUR uses channel color information in the AES50 datastream to automatically map input channels to DP48 Groups, including the following details:

  • Confirm/cancel that channels will be assigned to Groups 1-12 by color
  • Function clears all previous Group channel assignments
  • Input channels colored WH (white) or BK (black) will not be assigned
  • By default, channels will be mixed to their assigned Group with 0 dB level and panned to center
  • Channels can later be re-assigned manually by pressing the ASSIGN button

• GROUP NAMES IMPORT is an alternative method that allows you to name all Groups by using an external word processor (e.g., Microsoft Word, Open Office Writer, or a simple text editor) or a spreadsheet/calculation program, such as Microsoft Excel or Open Office Calc.

• Example procedure using a text editor:
  1. Open the text editor and start a new empty document.
  2. Write the group names in one line, separated by “, ” or “; “.
  3. Save the file in .csv format to an SD Card.
  4. Insert this SD card in your DP48.
  5. Go to SETUP screen page 8/8.
  6. Select GRP NAMES.
  7. Select IMPORT.

• Example procedure using a spreadsheet/calculation program:

1.  Open the spreadsheet/calculation program, and start with an empty chart.
2. Insert one group name per cell (from left to right).
3. Save the file in .csv format to an SD Card.
4. Now follow Steps 4-7 as described in the text editor procedure.

NOTES:

1. Do NOT use special characters, such as umlauts/vowels (Ä, Ö, Ü).
2. Case shift (large/small letters) is generally supported.
3. Group names are limited to max. 7 characters (incl. blank spaces).

The SETUP 7/8 screen allows you to choose a preference for the channel group when a RESET is done. Default is “12 STEREO”.

• CLEAR ALL deletes all input channel assignments from all Groups.

• ULTRANET 12 automatically creates 12 mono Groups:

  • Function clears all existing channel assignments from all Groups
  • A function maps AES50 input channels 33-44 to Groups 1-12.

• ULTRANET 16 automatically creates 8 mono and 4 stereo Groups:

  • Function clears all existing channel assignments from all Groups
  • A function assigns AES50 channels as follows:
  • Input channels 33-40 are assigned to Groups 1-8
  • Input channels 41-48 are assigned as stereo pairs to Groups 9-12

• 12 STEREO automatically creates 12 stereo Groups from the first 24 AES50 channels:

  • Function architecture assumes the FOH engineers will provide stereo stem groups for monitoring, rather than
    individual sources

  • The function will work best with groups of instruments, such as drums, horns, strings, choir, keys, bass, guitars,
    and so on, that mainly need level adjustments by the musician using DP48

Configuring input Channels and Groups
To access ASSIGN mode, first make sure the SETUP, SD-REC, MIX A, and MIX B buttons are not illuminated. In ASSIGN mode, the GROUP/CHANNEL ASSIGN screen will show the 48 available AES50 channels as a series of boxes with varying colors. The Group number and channel number will appear on the left side of the screen. In the GROUP/CHANNEL ASSIGN screen, you can judge the assignment status of an individual channel by the following color cues:
•Amber frame —­ channel is selected
•Blue frame —­ channel is assigned to the currently-active Group
•Flashing ­ — an audio signal is present in the channel

To assign/unassign a channel to Group
1. Press the INPUT CHANNEL/ASSIGN button to enter the GROUP/CHANNEL ASSIGN screen.
2. Choose a Group by pressing one of the GROUPS 1-12 buttons along the lower edge of the DP48 top panel. Channels assigned to the currently selected Group will appear blue.
NOTE: For easy channel identification, soloed audio from the selected AES50 channel will replace the MIX A/B audio.
3. Rotate the SELECT/EDIT push encoder to scroll to the desired channel. When the desired channel is ready for selection, the channel’s box will change color from a gray to an amber frame.
4. Press the SELECT/EDIT push encoder to assign/unassign the selected channel to the current Group. The selected channel’s box will change color to a blue fill with an amber frame to indicate the channel has successfully been assigned to the current Group.
*The incoming AES50 data stream may also include channel name and color-coding information, depending on the AES50 source.

Setting the input channel levels and panorama
The top-level MIX A/MIX B METERS screen only displays level settings for Groups.

Levels and panning for individual channels can only be adjusted and set individually within Groups. Once channel levels and panning are set within a Group, you can then balance levels and panning between entire Groups in the MIX A/MIX B METERS screen.

To edit levels and panning within a Group

1. Before editing channel levels and panning, make sure your overall Mix Volume and Group levels are loud enough that you can hear audio from the input channels.

2. Press the INPUT CHANNEL/EDIT button to enter the INPUT CHANNEL screen.

3. Choose a specific Group by pressing one of the GROUPS 1-12 buttons. The selected Group is automatically soloed
   and will replace the MIX A/MIX B audio.

4. Channels assigned to the currently selected Group will appear as blue boxes. If no blue boxes are visible, then the
   The selected Group is still empty.

5. Use the REVERB(<<) and PAN(>>) buttons to select an input channel within the group. The selected channel will appear as an amber box with a blue fill.

6. Rotate the SELECT/EDIT push encoder to adjust the currently-active Level or Pan parameter. Push the encoder to select between LEVEL and PAN.

7. Repeat steps 5-6 until the mix for Members in this Group is set, then consider moving on by pressing another Group button.

8. When done, pressing the EDIT button again will bring you back to the selected Group processing page, and Group Solo will be switched off automatically.

9. You can then take the following actions:
   • adjust that Group’s mix level in relation to the other Groups by turning the respective GROUP LEVEL control
   • make adjustments to that Group’s processing, i.e., Compressor, Reverb Send, or Equaliser.
   • press that Group’s button again to go back to the metering overview (idle) screen

To set Group levels in your final mix

To begin creating your final mix, you will be directly setting levels for entire Groups of channels by using the GROUP LEVEL knob.

1. Select a Group for level set by pressing one of the GROUPS 1-12 buttons. The system will take you to that Group’s GROUP/LEVEL screen.
2. Rotate the GROUP LEVEL knob to adjust the Group’s overall level by .5 dB increments. The left GROUP LEVEL knob will control LEVEL A going to MIX A, while the right GROUP LEVEL knob controls LEVEL B for MIX B.
3. Select another Group for level adjustment by pressing one of the GROUPS 1-12 buttons.
4. Repeat steps 1-3 until satisfactory levels have been set for all Groups.
5. To exit, de-select the currently active Group by pressing that Group’s GROUPS 1-12 button.

NOTE: At any time, you may adjust a Group’s level by selecting that Group’s GROUPS 1-12 button and then rotating the GROUP LEVEL knob for the currently active mix.

To set Group panning in your final mix
If necessary, entire Groups can be shifted together in the stereo field. Most of the time you will be setting up stereo panning when you first configure your AES50 channels into Groups, but when needed you can shift the entire Group’s overall panning at once.

1. Select a Group for panning adjustment by pressing the GROUPS 1-12 button.
2. Press the SELECT/EDIT push encoder to toggle between PAN A and PAN B (sent to MIX A and MIX B).
3. Rotate the SELECT/EDIT push encoder until the Group’s overall left-to-right panning is in the desired spot.
4. Repeat steps 1-3 until panning for all Groups has been set.
5. To exit, de-select the currently active Group by pressing that Group’s GROUPS 1-12 button.

Assigning one of the 12 Groups to the MY GROUP knob
Use the MY GROUP knob to make quick adjustments to your personal Group level versus the rest of the mix. The MY GROUP knob is available at all times for your personal level adjustments, no matter what operation menu is active in the display.

Your personal Group assigned to the MY GROUP knob may contain a single channel (e.g., vocals or guitar only) or several channels (e.g., vocals and guitar together, with levels balanced internally within the Group).

NOTE: Each MY GROUP knob can only be assigned ONE Group at any given time.

To assign a Group to the MY GROUP knob

1. Press and hold the MIX A or MIX B button.

2. Press the GROUPS 1-12 button of the Group you wish to assign to the MY GROUP knob. The screen will show the active MIX (A or B) in the big blue field, while the lower corner of the blue field will show the Group number assigned to the MY GROUP knob.

3. Rotate the MY GROUP knob to adjust the Group’s LEVEL indicated by the LED ring around the MY GROUP knob.

4. To see the LEVEL change expressed in dB values, press the assigned Group’s GROUPS 1-12 button. Then, when you turn the assigned MY GROUP knob, you will see the dB value changing for LEVEL A (MIX A) / LEVEL B (MIX B).
   NOTE: If a Group is not assigned to MIX A/B, the LEVEL A/B will not change by turning one of the MY GROUP knobs.

5. Press the Group’s illuminated GROUPS 1-12 button or the illuminated MIX A/B button (from Step 1 above), to exit back to the top-level MIX A/MIX B METERS screen.

6. You may now use the MY GROUP knob to make immediate adjustments to your personal Group’s mix level without having to access any additional screens.

7. To assign a different Group to MIX A or MIX B, repeat steps 1-2 and press a different GROUPS 1-12 button. To un-assign, the currently assigned Group from an MY GROUP knob, repeat steps 1-2 and press the GROUPS 1-12 button for the currently assigned Group. Now, the white field showing the Group number in the bottom corner will disappear from the big blue MIX A (or MIX B) field.
   NOTE: The first time you rotate the un-assigned MY GROUP knob, the system will launch a prompt window telling you how to assign a Group to the knob. Once you have assigned a Group to the MY GROUP knob, the automated prompt will no longer appear unless you later un-assign the Group without assigning another Group.

Adding EQ and reverb to your final mix
To add EQ and reverb to your final mix, follow these steps:

1. Press the MIX A/MIX B button to enter the MIX screen.

2. Press the LOW/MID/HIGH buttons to access the equalizer settings. Control buttons for LOW, MID, HIGH, COMP and
   REVERB will illuminate.

3. Rotate the SELECT/EDIT push encoder to raise or lower the level of the selected frequency band.

4. Press and rotate the SELECT/EDIT push encoder to adjust the selected frequency band’s cutoff (shelving) or center
   point (parametric). The composite equalization curve created by your adjustments will appear at the top of the screen.

5. Press the REVERB button to access the REVERB level settings.

6. Rotate the SELECT/EDIT push encoder to raise the REVERB level to your desired setting.

7. When you are done, press the MIX A/MIX B button to exit.
   NOTE: To change the reverb type, press SETUP and go to page 4/8 of the SETUP menu to choose between AMBIENCE, CLUB, HALL, or CATHEDRAL reverb programs.

Protect your hearing (setting Volume and Limiter)
The Limiter comes AFTER the final VOLUME control in the signal chain, so the specific Limiter threshold you choose will depend on how loud you set the final mix Volume.

For best results, we recommend you set your final MIX A/MIX B Volume first and then bring down the Limiter threshold to place a hard cap over the output that can contain any volume spikes and surges.

To prevent hearing fatigue or damage, consider setting the Limiter threshold as low as possible. With the right threshold setting, you will have a safe upper limit you cannot exceed no matter what happens in the heat of the performance.

To set the final VOLUME and LIMITER parameters, play some audio through your headset and follow these steps:

1. Press the MIX A/MIX B button to enter the MIX screen. Control buttons for LOW, MID, HIGH, COMP, and REVERB will illuminate.
2. Slowly turn up the VOLUME to the maximum level you will need for your headset.
3. Press the COMP button to access the LIMITER threshold for adjustment.
4. Rotate the SELECT/EDIT push encoder to lower the LIMITER threshold downward to your desired setting. We recommend you lower the threshold until the “L” indicator on the screen begins to light, which shows that the LIMITER is beginning to react to volume peaks in the signal.
5. When you are done, press the MIX A/MIX B button to exit.

SOLO mode
To help with identification, DP48 will automatically solo the audio for specific functions and under specific conditions, such as the following:

• ASSIGN— While assigning input channels to a Group, the selected input channel will be soloed for easy identification. When you exit ASSIGN, the channel solo will be deactivated automatically.
• EDIT— While editing the Group mix of the assigned input channels, the selected Group will be soloed automatically. When you exit EDIT, the Group solo will be deactivated automatically.
• Group Processing— If you wish to listen to a Group solo, e.g., to adjust that Group’s processing, just press and hold the respective GROUPS 1-12, MIC, or AUX IN buttons. That button’s LED will begin flashing, and the Group display will show a yellow “S” above the group number.

Solo Mode will also behave in the following ways:

• When you switch to a different Group or select the MIC or AUX IN buttons while in Solo Mode, the solo will follow your selection to the newly-selected Group or input.
• When you de-select the soloed Group or press any other button, such as MIX A/MIX B or SETUP, the solo is switched off automatically.
• You can also press and hold the soloed Group button again to switch off the solo.
