Frequently Asked Questions - DM1612 Lectrosonics

How do I install the DM1612F in a rack?

Mount the unit in a standard 19-inch rack using four rack screws. Use nylon washers to avoid damaging the front panel finish. Do not block the fan port on the rear. Connect the power cable to a stable AC source (100-240 VAC).

What type of audio cables should I use?

Use professional balanced audio cable (two conductors plus shield). For balanced connections, connect positive (+), negative (−), and ground (shield) to the 5-pin de-pluggable connectors. Do not tin the wires; strip insulation 1/8 to 3/16 inch.

How do I enable phantom power on an input?

Phantom power (+15 VDC) is software-selectable per input via the LecNet2 Control Panel GUI or front panel menus. It is switched via a programmable relay and two 2 kΩ resistors. Do not enable phantom power for unbalanced sources.

Can I control the DM1612F with a Crestron or AMX system?

Yes. Use the RED DB9-to-TRS cable (Part #21710-1) to connect to the RS-232 port of the control system. Do not use the black cable for this purpose. Refer to the wiring diagrams in the manual for pinouts.

How do I set up a Master/Slave configuration with multiple DM units?

Connect the Master unit's TX port to the Slave unit's RX port using the supplied CAT-5e cables. Repeat for second cable (do not cross them). Use the front panel LCD to set one unit as Master and others as Slaves. Only one Master per stack.

What software do I need to configure the DM1612F?

You need LecNet2 Control Panel software, available from the Lectrosonics website. Install it on a Windows XP/Vista/7 PC. Also install the USB driver if using USB connection. The software allows full configuration of inputs, matrix, outputs, and presets.

How do I connect the DM1612F to a computer?

Use either the black DB9-to-TRS cable (Part #21529-1) for RS-232 connection to a COM port, or the supplied USB cable. Only one unit can be connected via RS-232 at a time; multiple units can be connected via a USB hub.

What should I do if the unit does not pass audio?

Check that all connections are secure, inputs and outputs are correctly assigned in the software, and the matrix is routed. Verify that no mute or attenuator settings are active. If using phantom power, ensure the microphone is compatible. Save any changes to a preset.

How do I save and recall presets?

Use the LecNet2 Control Panel: go to the Preset menu and choose 'Store' to save the current configuration. To recall, select the desired preset. Presets take about 4 seconds to load and will mute audio briefly. For faster changes without audio interruption, use macros (except for filter adjustments).

What are the programmable inputs and outputs used for?

Programmable inputs can accept contact closures or 0-5V DC for external control of parameters like gain. Programmable outputs provide a ground closure (40V, 100mA max) to drive relays or LEDs. They are configured via the Control Panel GUI.

Hardware Installation

Installing the DM System into a Rack

The DM1624F and DM1612F occupy two rack spaces. The DM812 occupies a single space. Mount with 4 rack screws using the appropriate mounting holes. It is recommended to use nylon washers to prevent damage to the front panel's finish when tightening the screws.

Do not obstruct the fan port on the 2RU models.

For North American installations, connect the Power Cable supplied with the unit between the DM and a stable power source. DM processors have internal switching power supplies that can tolerate voltages ranging from 100 VAC to 240 VAC. Use an approved power cable for installations outside North America.

Cables

It is recommended to use lacing bars for cable strain relief when mounting in a rack. Use only professional audio cable with proper shielding - typically, two conductor plus ground/shield.

Audio Connections

The analog audio inputs and outputs are connected through 5 pin de-pluggable connectors. Strip the insulation back 1/8 to 3/16" but do not tin (apply solder to) the leads. Insert the wire into a de-pluggable connector, leaving less than 1 mm of bare wire exposed, then tighten the retaining screw.

Note the labeling on the DM Chassis for the positive and negative leads. Ground is shared between two connections (the center pin). For balanced connections, all three leads can be connected.

NOTE: The DM Series does not have a "pin 1 problem."

Audio Inputs

Unbalanced Sources

Unbalanced audio sources (positive and ground) include items such as consumer VCR's, DVD players, etc., and may use both two wire and three wire cables. In either case, the positive output from the source should be connected to the appropriate positive (+) input on the DM. The shield or negative (−) output should be connected the DM's negative (−) input. Two wire cables should have a jumper between the DM negative input and ground. Three wire cables should have the shield connected to the DM's ground input and the shield and negative (−) leads joined together at the unbalanced source end.

WARNING: Do not activate phantom power for unbalanced sources. Refer to online help files after the software is installed.

Balanced Sources

Balanced differential sources from external equipment and microphones should be wired according to Balanced source to DM input (3-Wire). (See illustration.) When connecting balanced sources to the DM, it is important to not connect chassis ground (shield) to either signal conductor.

Phantom Power

The DM supplies +15 VDC phantom power to the audio inputs via a programmable switch and two 2 k resistors. (See illustration below.)

However, the true phantom power available at the microphone may be less due to voltage drop across the microphone itself (source resistance). In some cases, the voltage drop may be enough to result in marginal performance. The following formula can be used to determine how much phantom power will be available to a particular microphone.

$$ V _ {p h} = 1 5 \mathrm{V} - (1 k) \left(I _ {\text { mic }}\right) $$

Where:

Programmable Gain Preamplifiers with Software Switchable Phantom Voltage

Equivalent Circuit

V_ph = the actual voltage available at the microphone. (Microphone specifications list this as the minimum recommended phantom voltage value. To minimize problems, the calculated Vph should exceed this value.)

I_mic = the current draw of the microphone. (Refer to individual microphone specifications for this value.)

Examples:

Microphone Number 1;

From Specification Sheet: V_ph(min) = 11 V I_mic(typical) = 4 mA

$$ \begin{array}{l} V _ {n h} = 1 5 \mathrm{V} - (1 \mathrm{k}) (. 0 0 4 \mathrm{A}) \ V _ {p h} ^ {p h} = 1 5 \mathrm{V} - 4 \mathrm{V} = 1 1 \mathrm{V} \ \end{array} $$

Since the calculated Vph is equal to Vph from the microphone specification sheet, this is a marginal situation.

Microphone Number 2:

From Specification Sheet: V_ph() = 9V I_mic(.) = 2mA

$$ \begin{array}{l} \mathrm{V} _ {\mathrm{ph}} = 1 5 \mathrm{V} - (1 \mathrm{k}) (. 0 0 2 \mathrm{A}) \ \mathrm{V} _ {\mathrm{ph}} = 1 5 \mathrm{V} - 2 \mathrm{V} = 1 3 \mathrm{V} \end{array} $$

Since the calculated Vph is greater than the Vph from the microphone specification sheet, this is an acceptable situation.

Audio Outputs

All outputs are a balanced differential configuration. Some outputs include an attenuator to reduce the signal to mic level. Use the outputs marked as MIC/LINE OUTPUTS for mic level applications. Using the other outputs marked LINE OUTPUTS with control panel attenuation can result in up to 40 dB of additional noise.

NOTE: Using a Line Output with digital attenuation applied with the Control Panel to achieve Mic Level will result in added noise.

When the DM output is connected to a balanced input, wire it as indicated in DM Out to Balanced Input (3-Wire). Select Mic or Line (as appropriate) either from the front panel LCD interface or via the software GUI.

When the DM output is conencted to an unbalanced input, wire it as indicated in DM Out to Unbalanced Input (3-Wire), or DM Out to Unbalanced Input (2-Wire).

Programmable Inputs

Programmable inputs are provided to enable external control over a variety of parameters. Each input can respond to either a contact closure or a continuous voltage. The following illustrates common connections to the programmable input pins. (See also Programmable Inputs and Outputs Wiring Diagram.)

Potentiometer Connection for Analog Control of Gain

Contact Closure as Programmable Input

DC Voltage Source as Programmable Input

No external pull-up resistors are necessary because each programmable input is internally pulled up through a 100K resistor to +5V. When using a continuous voltage with one of the programmable inputs, the function of the programmable input must be set to either Analog In Control or Analog Out Control on the Programmable Inputs control tab in the Control Panel GUI. See the Programmable Input tab in the Control Panel software Help for setting all programmable input parameters.

Programmable Inputs and Outputs (DM1612F shown)

Programmable Outputs

Programmable outputs are used to indicate either channel activity or the current state of a programmable output. Each programmable output is the electrical equivalent of a contact closure to ground. When a programmable output is "active", it conducts current to ground. When the programmable output is "inactive", no current flows to ground. The maximum usable voltage for the programmable outputs is 40 V and they will safely conduct up to 100 mA DC continuous. Following are some typical uses for the programmable outputs.

Note: The diagram shows an external DC source powering the relay coil. This is necessary whenever coil voltages exceed 5 V.

Both LEDs and 5V relay coils can be powered by the +5 V DC pins on the programmable input connector, as long as the maximum combined current for all LEDS and relay coils does not exceed 100 mA.

Programmable Input/Outputs Connections

Looking at the male connector on the rear panel of the processor, the pinouts are as follows:

LED is on when the programmable output is active

LED is off when the programmable output is active

Relay is on when the programmable output is active

Expansion I/O ports

The four RJ45 connectors on the rear panel are used to interconnect LecNet2™ units together. These ports are only used to transfer digital audio information via the Digital Audio Network Interface (DANI) between the units.

WARNING: The Expansion I/O connectors are NOT EtherNet, CobraNet or any other network based device interconnects. Connecting them to Ethernet, CobraNet or other network based device may cause damage to either unit.

Programmable Inputs Wiring Diagram Example

PROGRAMMABLE INPUTS/OUTPUTS

In a stacked configuration, one unit must be configured as the Master unit and the others as Slave units. Configuring a unit as a Master or a Slave can be done using the front panel LCD and controls or the Control Panel GUI interface.

Note: In order to use the convenient Control Panel GUI, LecNet2™ must be installed on the attached computer system. (See Installing LecNet2™ Software and USB Driver.)

To connect the Master/Slave units, plug one end of a 12 inch Cat5e cable (two are supplied with each with unit) to the transmit (TX) port on the Master unit, and connect the other end to the corresponding receiver (RX) port on the Slave unit immediately below the Master. Repeat this procedure with the second Cat5e cable. (See Expansion Port Digital Audio Network Interface Interconnection Diagram.)

CAUTION: Do not connect these ports to each other on a single unit, and to not cross the cables between the units.

Master/Slave Configuration

When stacking multiple units, one unit is always set as the Master and all subsequent units are set as Slaves. The LCD interface is used to do this.

Initial Setup

The initial setup of a DM system is a relatively simple three step process: connect the unit to the computer, turn on the computer and select the appropriate control panel, preset the input, matrix and output. This process assumes that LecNet2™ and, if necessary, the USB driver have been previously installed. If they have not been installed, please refer to Installing LecNet2™ Software and USB Driver.

1) Connect the computer system to the DM unit using either the BLACK DB9 to stereo mini (TRS 1/8") cable for RS-232 communications or the USB cable for USB control. (Both cables are included with the unit.)

Note" Only one DM unit at a time can be connected to the computer system using the RS-232 cable. Multiple units may be connected to the computer system using a USB hub.

2) Turn the computer system on. After the boot sequence is complete, click Start, then All Programs.
3) Select LecNet2, then select the control panel from the list for the DM unit being set up.

4) If the "Just a Reminder" dialog appears, click OK to continue.
5) Click Connection on the Main Menu bar, then select the type of connection between the computer system or external control system and the DM unit. The choices are:

USB - used when the computer is connected to the DM unit via the front or rear panel USB port.

Network - One or more DM devices may be made available for network connections by connecting them to a gateway server acting as a middleman, receiving commands for a DM over a network connection, and forwarding them to the DM device connected via USB.

Extron IPL T S - One or more DM devices may be made available for network connections by connecting them to an Extron IPL T S ethernet control interface. The IPL T S interface acts as a middleman, receiving commands for a DM device over a network connection, and forwarding them to the device via an RS232 port. To work as a gateway server the IPL T S interface must be a member of some local area network (LAN) or the Internet, by means of an Ethernet connection.

Serial->COM1 - An RS-232 port for RS-232 communications between the DM and the computer sytsem, or for connecting the DM to an external control system such as those made by Crestron® or AMX®.

Serial->COM2 - Same as above.

Go Offline - No Connection Made, this mode can be used for off line configuration and is the default mode.

The DM can be configured in the installation or a configuration file can be created off line in advance. The minimum required setup to pass audio includes: Inputs, Matrix and Outputs. Input and output filters, compressors and delays are used to tailor the system for specific audio situations. While these parameters can be set up through the front panel LCD and controls, the Control Panel GUI offers a much more robust and intuitive interface.

Initial Setup Hints

1) The GUI interface is quite intuitive. As a recommended first step, we suggest you select Labels from the Menu Bar and type in all the input and output labels. This will simplify further setup steps because you will be able to easily keep track of which input or output you are adjusting.
2) The right click is powerful in this interface. You can activate quick access to a number of setup functions (for example - right click in any input box in the INPUTS tab). It also allows some powerful cut and paste capabilities - especially in the matrix setup and the filter (both input and output).
3) Store startup settings in a startup default preset. (See Storing and Recalling Presets in the online HELP application.)
4) Presets will take about 4 seconds to switch due to the many parameters in the unit - audio will switch off temporarily during a preset switch to avoid feedback. If you need quicker response with no interruption to the audio, use macros instead - try using the macro recorder for making any changes. The only changes that cannot be made in a macro are filter adjustments, such as EQ.

5) Store presets after changes are made and not before they are made.

6) Help is always available by clicking Help on the Main Menu Bar. This Help is a comprehensive resource and includes the latest revisions to the software and firmware.

IMPORTANT: ANY CHANGES MADE DURING SETUP MUST BE SAVED IN THE UNIT VIA THE PRESET MENU.

Service and Repair

If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting cables and then go through the TROUBLESHOOTING section in this manual.

We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection, send the unit to the factory for repair and service. Don't attempt to adjust any controls inside the units. Once set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment.

There are no adjustments inside that will make a malfunctioning unit start working.

LECTROSONICS' Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone for out-of-warranty repairs.

Returning Units for Repair

For timely service, please follow the steps below:

A. DO NOT return equipment to the factory for repair without first contacting us by letter or by phone. We need to know the nature of the problem, the model number and the serial number of the equipment. We also need a phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed your repair through our receiving and repair departments. The return authorization number must be clearly shown on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the proper packing materials. UPS is usually the best way to ship the units. Heavy units should be "double-boxed" for safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or damage to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
