WARNING CAUTION! Keep this system away from rain and moisture! FOR YOUR OWN SAFETY, PLEASE READ THIS USER MANUAL CAREFULLY BEFORE YOUR INITIAL START-UP! SAFETY INSTRUCTIONS Every person involved with the installation, operation and maintenance of this system has to: be qualified follow the instructions of this manual CAUTION! Be careful with your operations.
For replacement use fuses of same type and rating only. • Prevent distortion! Make sure that all components connected to the DLM-26 have sufficient power • ratings. Otherwise distortion will be generated because the components are operated at their limits.
Description of the device Features The DLM-26 is a professional Digital Loudspeaker Management System: • Active frequency filter with slopes up to 48 dB/octave split up the audio-signal into different frequency bands • 60 user programs can be memorized • Up to 630 ms signal delay for the inputs and outputs adjustable •...
Backside 12) IEC Connector + Fuse 13) RS232-SOCKET 14) MIDI OUT 15) MIDI THRU 16) MIDI IN 17) 6x XLR Output Socket 18) 2x XLR Input Socket LED Input Barographs The input barographs respond to –30dB input and also indicate digital clipping. These show the input level: -30dB, -20dB, -12dB, -6dB, -3dB, LIMIT, OVER (=CLIP).
Installation Remove all packing materials from the DLM-26. Check that all foam and plastic padding is removed. Screw the equipment into a 19" rack. Connect all cables. Always disconnect from electric mains power supply before cleaning or servicing.
Insert the CD in your computer and install the CD by clicking on the DLM Setup icon. Within 5 seconds this handy piece of software is installed. Be sure to connect the DLM-26 via a RS232-cable to your computer. You can already make a few different choices in the Start-up screen.
Programs Saving programs You can save up to 60 programs in the memory of the DLM-26. Press the SAVE/ENTER-button (7) to store the program in the memory. The display shows you the last used program on the screen. Press the PREV/NEXT-buttons (8+9) for adjusting program 1-60.

Delete programs In Setup-mode, press either the - button (5) or turn the jog-wheel (4) clockwise. You will enter the Delete Program mode. Choose the Program to be deleted using the - buttons (5+6). Press ENTER (7) to delete a program. Pressing the PREV/NEXT buttons (8+9) at any time will exit the Delete Program mode.
Setup-menu Press the PREV/NEXT-buttons (8+9) in order to navigate in the setup-menu. Adjust your setting with the - buttons (5+6) or the jog-wheel (4). Press the Recall-button (10) in order to leave a mode. Stereo-link The stereo-link links two outputs with each other depending on the selected operation mode. In 2-way mode, the outputs 1 and 3, 4 and 6 and 2 and 5 are linked.
Configuration Selection of the operation mode (Config) The DLM-26 can be adjusted in the following operation-modes: Mono 2 Channel 3 Way 3 Channel 2 Way Note: if you change the operation-mode, all routings and links will be changed, too. Always select the operation-mode first.
Operation-mode 3-way • In the operation-mode 3-way, input channel A is routed to outputs 1, 3 and 5. • Input channel B is routed to outputs 2, 4 and 6. • All delay links is switched off. • Stereo Link is switched on. •...
Crossover mode Crossover mode allows you to link the crossover frequencies of the associated bands together for ease of setting. For example, when in 'Both' mode (=linked) changing the frequency of the Hi slope of an output channel set up as say 'low' band will also change the frequency of the Lo slope in the adjacent 'Mid' band output channel.
Save/Enter-button (7). The display shows the following message and then enters the Lock All mode. Note: If you activate the OEM-lock ( ) and save the program (with OEM-lock), the DLM-26 is completely locked. There is no more possibility to unlock the OEM-lock ( ) as described above. In order to...

If the owner lock is activated, either an individual or all parameters of a program can be locked. This lock is used for avoiding unintended/unwanted changes to the DLM-26. When Owner Lock is activated, only the display contrast or the Owner Lock can be adjusted.
Midi Channel Midi can be used to transmit and receive programs or to send the complete memory to another DLM-26 (Sys-Ex Dump). Adjust the Midi-channel with the - buttons (5+6). Both the sending and receiving device needs to be set to the same MIDI channel to communicate correctly.
Input Equalizer Assignable equalizer With the DLM-26, you can assign individual equalizers for every channel (IN A, IN B, OUT 1-6). The number of assignable equalizers depends on the available system memory. If the display shows „No more filters“ you can clear system memory by deleting other programs or equalizers on other channels.
Output-adjustments By pressing the jog-wheel you can jump to Output 1-6. If two outputs are linked, every equalizer change or crossover-frequency change affects both channels. If you press the PREV / NEXT-buttons (8+9), you can choose from: Name Please select the best fitting name from the name list. The Output Name is selectable from a pre-programmed list.

Limiter The DLM-26 has a limiter-function with independent limiters (one per output), which are adjustable between -10 and +20 dB. There are 2 primary reasons for using a limiter: 1. Prevention of amplifier clipping 2. Limit the amount of power transmitted to the speakers The limiter serves as an additional clipping protection to avoid speaker damage.

Delay-Linking Via the delay-link you can link different channels in the delay. In this way, you can keep an already adjusted delay between driver and speaker of a cabinet for a delay between clusters. An offset-link is a relative link between the channels, i.e. if a parameter value is changed; the same parameter of the other channel automatically receives the relative value.
Crossover types and frequencies Low pass filter type For the lower crossover frequency of the outputs, the following filter types are available: • Bessel 12 and 24dB/octave, • Butterworth 6, 12, 18, 24 and 48dB/octave • Linkwitz-Riley 12 and 24 and 48dB/octave The display shows the following different options: •...

Assignable Equalizer Multiple Equalizers can be assigned to individual Input and Output channels. If there is no EQ on the currently selected channel (and there are filters available), the PREV-button will step into an unused Bell EQ with 1 KHz frequency, 0 dB cut/boost and width of 0.3. Further Equalizers can only be assigned to a channel after this EQ is used first by applying some degree of cut or boost, pressing the PREV-button then steps into a new EQ.
Connection Cables Take care of the connector cables, always holding them by the connectors and avoiding knots and twists when coiling them: This gives the advantage of increasing their life and reliability, which is always to your advantage. Periodically check that your cables are in good condition, that they are correctly wired and that all their contacts are perfectly efficient: a great number of problems (faulty contacts, ground hum, discharges, etc.) are caused entirely by using unsuitable or faulty cables.
3. If all of the above appears to be O.K., plug the unit in again. 4. If you are unable to determine the cause of the problem, do not open the DLM-26, as this may damage the unit and the warranty will become void.
