DL16
1. Introduction
The DL16 is an audio interface designed to provide analog and digital I/O for a variety of live and studio applications. DL16 has the flexibility to work as a stage
box/digital snake. This line is compatible with Midas M-series, Behringer X and WING series, and P16 personal monitoring system.

1. PHANTOM POWER – Individual LED indicators light when the phantom
power is activated in the corresponding channel.
2. IN 1-16 – These 16 Midas PRO mic preamps are remote-controllable from
Midas M-series, Behringer X and WING series consoles. Alternatively, each
channel's gain and phantom power can be configured directly on the
front panel.
3. GAIN – Hold down the GAIN button and turn the SELECT/ADJUST knob (9) to
set the gain applied by the preamp on the selected channel. The gain ranges
from -2.5 dB to +45 dB.
4. DISPLAY – This screen shows the selected channel number, its gain setting,
the splitter configuration, or the sample rate when the DL16 is configured as
clock master.
5. NETWORK LINK – The LEDs light green to indicate the devices on the
A or B AES50 ports are connected and their word clocks are synchronized.
If a device is connected but not synchronized, the LED will blink red.
6. 48 V – The 48 V button activates phantom power on the currently selected
mic input.
7. STATUS – These LEDs show the operation mode of the DL16. See section
5: Operation Modes for details on the signal flow in each setting. The HA
LOCKED LED indicates that preamp gain adjustment has been blocked by the
remote-controlling console.
8. CONFIG – Holding down the CONFIG button in combination with other
buttons allows access to multiple settings. Details are explained throughout
this guide.
9. SELECT/ADJUST – This knob scrolls through the channels, adjusts the gain
of the currently selected input and changes the operation mode.

10. METER – This LED strip shows the signal level on the currently
selected channel.
11. MONITORING LEVEL – Use this knob adjusts the volume of the ¼" TRS
headphone jack. Individual analog and digital inputs as well as digital stereo
pairs can be monitored through the headphone jack.
12. OUT 1-8 – These 8 balanced XLR balanced outputs can be used to feed the
PA system or for monitoring mixes for the musicians on stage.
13. POWER – Turns the unit on and off.
14. USB – This USB type-B connector is used for firmware updates.
15. AES50 A/B – These two AES50 ports allow transmission of audio and
MIDI data to and from compatible Midas and Behringer consoles. Up to
48 inputs and 48 outputs at 44.1/48 kHz and 24 bits can be transmitted
using a single Ethernet cable. A second port allows up to three DL16 to be
cascaded (see section 6 for details). Use shielded CAT5e Ethernet cables with
terminated ends.
16. ULTRANET – This port connects the stage box to Behringer P16-M personal
mixers or P16-D distribution hubs. 16 tracks are sent using a shielded
CAT5 cable.
17. ADAT – These two Toslink connectors provide 16 additional digital output
channels. The signals sent via these connections are programmable.
See section 5: Operation Modes for details.
18. MIDI IN/OUT – Standard 5-pin MIDI cables can be connected to the MIDI
IN/OUT jacks for MIDI communication to and from the console, and for
remote control of the preamp gain and phantom power.
3. Firmware update
Follow these steps to update the stage box firmware:
1. Download the file from midasconsoles.com.
2. Connect the powered-off DL16 to the computer.
3. Hold down the CONFIG button and turn on the DL16.
4. Run the firmware application on your computer. Wait for the firmware to be
updated and unplug the USB connection.
5. The stage box's DISPLAY will show the installed firmware version upon
powering on the DL16.
4. Headphone monitoring
Individual input channels or stereo pairs can be selected for monitoring
over headphones.
Mono channel monitoring
To select an individual input channel for mono monitoring, follow these steps:
1. Press the SELECT/ADJUST button once to toggle between three different
input groups: 16 analog inputs (DISPLAY shows "In"), 48 digital inputs via
the AES50 A port (DISPLAY shows "A"), and 48 digital inputs via the AES50 B
port (DISPLAY shows "b").
2. Turn the SELECT/ADJUST knob to select the desired channel.
3. The selected mono channel will be monitored through the headphone jack.

Quick Start Guide
Stereo monitoring
To select a stereo pair of inputs for monitoring, follow this procedure:
1. Hold down the CONFIG button and press the SELECT/ADJUST knob to activate
the stereo monitoring of the AES50 digital inputs.
2. Hold down GAIN and turn the SELECT/ADJUST knob to select the
stereo pair from the AES50 A port that will be monitored through the
headphone connector.
3. Hold down the CONFIG button and press the SELECT/ADJUST knob again to
exit the stereo monitoring mode.
5. Operation modes
By holding the CONFIG button and turning SELECT/ADJUST knob, the DL16 can
be configured to suit many different applications. The STATUS LEDs indicate the
current settings.
5.1 Standard
1-8
The DL16 is in Standard (default) mode when all the configuration STATUS LEDs
on the DISPLAY are off. The 16 XLR inputs are routed to the first 16 AES50 A
output channels. The AES50 B out is a copy of the AES50 A in.
