Frequently Asked Questions - DL252 Midas

How to power on the DL252?

Plug both power cords into separate wall outlets, then toggle the power switches on the rear one by one (not simultaneously). The LEDs on the power section should light up.

What to do if the red AES50 error LED lights up?

This indicates an AES50 connection problem. Check the EtherCon® cable, connectors, and ensure the master device is powered on. If the problem persists, contact a qualified technician.

How to configure the sample rate?

On the front panel, in the sample rate section, use the push button to toggle between 48 kHz and 96 kHz. The corresponding LED lights up to indicate the active setting.

Can I use the DL252 with a non-Midas console?

The DL252 is designed to work with Midas digital consoles via AES50. Use with other brands is not guaranteed; the control mode must be set accordingly (mode 2 for use as a multipair snake).

How to mute all outputs quickly?

Press and hold the MUTE button on the rear panel for at least one second. The built-in LED lights up, and all outputs are muted. Release it to restore sound.

Midas offers a limited 3-year warranty for hardware and manufacturing defects. Keep your proof of purchase. Online registration at www.midasconsoles.com is recommended.

Can I repair the device myself?

No, the interior contains no user-serviceable parts. Any unauthorized opening voids the warranty. Contact an authorized dealer or qualified technician.

How to identify my device on the network?

Use the ID select section on the front panel. Press the push button to choose a unique identifier (1 to 4) – the corresponding LED lights up. This ID must match the one configured in the console.

¡Bienvenido!

DL251/DL252 Getting Started

EN 2. Getting Started

This section shows you how to unpack, install, connect up, switch on and configure the DL251/DL252 unit.

This equipment is supplied by a mains voltage that can cause electric shock injury.

Before installing, setting up or operating this equipment, make sure that you have read and fully understand all of this section and the “Important safety instructions” at the front of this manual.

Refer to additional safety information on the top cover of the unit.

Unpacking

Carefully unpack your DL251/DL252 equipment package.

Then, inspect the DL251/DL252 unit carefully for any signs of damage that may have occurred during transit and notify the courier immediately if you discover any.

Check the contents of your DL251/DL252 equipment package. If there are any parts missing, incorrect or faulty, please contact your local distributor or Midas at the address at the front of this manual.

Please retain the original packing in case you should need to return the equipment to the manufacturer or supplier, or transport or ship the unit later.

Installation

Before installing and operating this equipment, make sure it is correctly connected to the protective earth conductor of the mains voltage supply socket outlet through each mains lead.

Ideally a cool area is preferred, away from power distribution equipment or other potential sources of interference.

Do not install the equipment in places of poor ventilation.

Do not install this equipment in a location subjected to excessive heat, dust or mechanical vibration. Allow for adequate ventilation around the equipment, making sure that its fans and vents are not obstructed. Whenever possible, keep the equipment out of direct sunlight.

Mount in rack only.

Power

Both supply cords must be unplugged to ensure complete de-energisation of the unit.

The internal power supplies are of the switch mode type that automatically senses the incoming mains voltage and will work where the nominal voltage is in the range 100VAC to 240VAC.

Two mains inlets are provided on the rear panel. The correct leads for connection in the area to which the unit was shipped are supplied with the unit. The equipment should only be plugged into the mains outlets using the supplied leads.

Each mains inlet must be sourced from its own separate wall-mounted mains outlet socket. Otherwise, their mains sources must be suitably distributed so as to meet local safety regulations.

Make sure the Volex locking type plugs, fitted on each supplied mains cable, are securely fitted to the mains IEC connectors on the unit. When fitted properly the Volex plug locks into place, preventing it from working loose, or being inadvertently knocked loose or pulled out. When fitting or removing a Volex plug, always hold the plug itself and never use the cable, as this may damage it. Never insert or remove an electric plug with wet hands.

When switching the unit on/off, switch the mains power switches on/off one at a time. Do not switch them on/off simultaneously.

Handling the equipment

When lifting or moving the equipment, always take its size and weight into consideration.

Completely isolate the equipment electrically and disconnect all cables from the equipment before moving it.

Do not insert your fingers or hands in any gaps or openings on the equipment, for example, vents.

Electric fields

In accordance with Part 15 of the FCC Rules & Regulations, “... changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.”

Should this product be used in an electromagnetic field that is amplitude modulated by an audio frequency signal (20Hz to 20kHz), the signal to noise ratio may be degraded.

Degradation of up to 60dB at a frequency corresponding to the modulation signal may be experienced under extreme conditions (3V/m, 90% modulation).

Connecting up

Connect up the rear panel of your unit as follows (see Chapter 5. Connections on page 34):

• Inputs — connect your XLR mic/line inputs (up to 48 on DL251 and 16 on DL252).
• Outputs — connect your XLR line outputs (up to 16 on DL251 and 48 on DL252).
• AES50 audio — connect the AES50 audio sockets to the console/snake.
• Ethernet — connect the Ethernet control socket to an external computer for remote control when used in a snake configuration if required.
• MIDI — connect the three MIDI 5-pin DIN connectors to the MIDI equipment if required. (For use with Midas consoles only.)
• Mains power — connect the dual redundant IEC connectors of the mains cables into the rear of the unit and then plug them into separate mains power outlets (see

"DL251 and digital console (96kHz operation)" on page 34).

Switching on/off

When switching the unit on/off, press the two mains on/off switches one after the other. Do not press them simultaneously.

After you have connected up your DL251/DL252 it is ready to be switched on.

Switch off the mains on/off switches on the rear of the unit, one after the other.

To fit/remove a Volex locking type mains plug

A Volex locking type plug is fitted on each supplied mains cable, which plugs into a mains IEC connector on the unit. When fitted properly the Volex plug locks into place, preventing it from working loose, or being inadvertently knocked loose or pulled out.

To fit a Volex plug, insert it into the mains IEC connector and push it in until it locks in place. Then, check to make sure it is securely locked in place.

To remove a Volex plug, release its locking device and then pull it out. Don't hold the cable, as this may damage it.

Configuration

After you have switched on the DL251/DL252, you can configure the following as required.

- ID number.

- Control mode.

- Clock source.

• Sample rate of clock source.

To configure an option

In the desired section, press the round button repeatedly to cycle through the options until the LED of the one you want is illuminated.

DL251/DL252 Front Panel

EN 3. Front Panel

1 The psu panel monitors the two voltage supplies. There are five yellow LEDs per voltage supply, and each LED represents a voltage rail. An LED will illuminate when its respective voltage rail is active.
2 The ID select panel lets you select the ID number of the unit. This is a unique number that is recognised by the system and distinguishes it from any other similar unit(s) in the network. One of the four green LEDs will be illuminated to indicate the currently selected ID.
3 This control mode panel lets you select the control mode of the unit. Use this panel's pushbutton to select mode 1 if the unit is connected to a console or mode 2 if the unit is used in a snake configuration. Either of the two green LEDs will illuminate to show which control mode is selected.
4 The clock panel lets you select the synchronisation source of the unit. Use this panel's pushbutton to select the internal clock of the unit (int) or an external AES50 source (ext). The external source is the clock of the connected device (usually a Midas digital console) whose signal is transmitted via the AES50 audio connector. Either of the two green LEDs will illuminate to show which clock source is selected.
5 The sample rate panel has a two green LEDs, which indicate the currently selected sample rate (96kHz or 48kHz).
6 The Ethernet control panel has a single green LED, which has three states of illumination: flashing = active; on = connected; and off = not connected.

7 The AES50 audio panel shows the health status of the communications of the AES50 connections. If the green ok LED is illuminated, communication is good. However, if the red error LED is illuminated, there is a problem on that connection.
8 There are four air intakes for fan cooling. Do not obstruct.
9 There are four cut-outs for rack mounting fixings.

DL251/DL252 Rear Panel

EN 4. Rear Panel

1 Unit serial number label.
2 Ventilation grills, which provide an air outtake for fan cooling of the inside of the unit.
3 Male XLR chassis connectors, which provide outputs for line equipment. Each socket has a red LED that illuminates when mute is on for that output.
4 Female XLR chassis connectors, which provide inputs for mic/line equipment. Each socket has a red LED that illuminates when +48V phantom power is on for that input.

5 The diagnostics connector is a 9-way D-type connector for connecting a laptop/PC by service personnel for diagnostics purposes. This is not an operator function and is only to be used by service personnel.

6 The MUTE button mutes all the outputs simultaneously when held down for longer than one second. It has an integral LED that illuminates when mute is active.
7 The boot mode switch selects between normal operation and a service personnel-only configuration boot mode. It has an adjacent red LED, which illuminates to show when the unit is in service only configuration mode.
8 There are three MIDI (musical instrument digital interface) sockets — MIDI in, MIDI out and MIDI thru — for connection of a MIDI device, such as a synthesiser. The MIDI in socket receives MIDI data, and the MIDI thru socket gives out the same MIDI data that is received by the MIDI in socket. The MIDI out socket gives out MIDI data generated by the attached Midas Digital Console.

9 Three AES50 audio EtherCon® sockets provide connection to the console/snake and pass audio and control data in both directions. Each socket has a pair of red and green LEDs, which indicate the following:

• Green pulsating and red extinguished = valid audio and valid control data; active link.
• Green constantly illuminated and red extinguished = valid audio and valid control data; standby link.
• Green extinguished and red illuminated = no audio; link has failed.

10 The Ethernet control EtherCon® socket provides connection to an external computer for remote control when used in a snake configuration. This socket has a pair of red and green LEDs that indicates the following:

• Green LED illuminated = cable connected at both ends.
• Green LED extinguished = cable not connected at both ends.

Mains power

! Each mains inlet should be sourced from its own separate wall-mounted mains outlet socket. Otherwise, both mains sources must be suitably distributed so as to meet local safety regulations.

The mains is supplied to the DL251/DL252 via dual redundant mains inlets.

11 Dual redundant power supplies.
12 Mains on/off isolator switch.
13 Mains IEC socket.

Important:

The unit has Volex locking type plugs fitted on their supplied mains cables, which plug into the mains IEC connectors. When fitted properly the Volex plug locks into place, preventing it working loose, or being inadvertently knocked loose or pulled out.

DL251/DL252 Using The Unit

EN 6. Using The DL251/DL252

Although the DL251/DL252 has only limited user functionality, this section shows how to mute all outputs simultaneously and how to use the boot mode.

To avoid electrical shock, never operate the equipment with the covers removed. Do not operate the equipment or any of its parts if safety guards are ineffective or their effectiveness has been reduced.

Muting all outputs simultaneously

The mute feature mutes all outputs simultaneously and also disconnects all the mic amps from the AES50 interface. This will have the effect of muting any other outputs that are sourced from these inputs.

The MUTE button will activate after being pressed for one second and will de-activate after it has been released for half a second. The button's integral red LED will illuminate to show when mute is active.

Using the boot mode

This service personnel only function is used to select between normal operation and configuration mode.
