Pull the handles out to the front. To also remove the rack ears (E), remove the remaining two screws and then remove the rack ear.

About this product

The DLA26 is a 2-in/6-Out stereo signal splitter, aka distribution amplifier. It can feed up to 6 individual output from 2 inputs, and thus allows to build large multi-zone systems. For extended flexibility, all outputs can be switched to mono and have their own switchable 100Hz high pass filter, making it easy to integrate auxiliary mono zones which utilize smaller speakers. Apart from signal distribution, the DLA26 can also integrate basic emergency and evacuation functionality into a sound system.

Configuration

The DLA26 can be configured to meet certain operational requirements by setting internal jumpers. As a factory default, all jumpers are set to the ON position.

WARNING! Any action which requires opening the product shall only ~ be expedited by qualified service technicians. Remove the AC cord before opening the product. Be aware that the warranty may be void unless you are an appointed panasonic installer, contractor or technical service provider.

To change the jumper settings, unscrew the top lid from the product and remove it. The jumpers are located on the rear PCB assembly as per following illustration and functional description:

A Emergency Mute. Jumpers JP102 (for Signal-A output) and JP104 (for Signal-B Output) decide whether the loop-through outputs of the feeding signals A and B carry forward the muting of the signal when a signal become present at emergency input (12). This setting can be useful if the input signal is supposed to be forwarded to a different subsystem, but that subsystem has its own emergency features.
Mostly this jumper will be set in conjunction with the emergency signal jumpers (see following point B).

B Emergency Signal. Jumpers JP103 (for Signal-A output) and JP105 (for Signal-B Output) decide whether the loop-through outputs of the feeding signals A and B will carry forward the emergency signal when such signal becomes present at emergency input (12). This setting can be useful if the input signal is supposed to be forwarded to a different subsystem, but that subsystem has its own emergency features. Mostly this jumper will be set in conjunction with the emergency mute jumpers (see previous point A).

Note that theses jumper do only influence the feedthrough outputs of the input signals A and B. They have no influence on the outputs 1-6 whatsoever.

Controls and Connections

1. AC inlet and fuse holder. Use the supplied AC cord to connect the unit to AC mains. Make sure voltage and frequency stated and set on the unit comply with your local AC supply. The fuse can be accessed by the small drawer at the AC inlet. To change the fuse, unplug the AC cord first, pull out the fuse drawer and replace the fuse ONLY with a fuse of SAME voltage and rating. If the fuse blows again after replacement, hand over the unit to qualified service personnel.

2. Stereo Signal “A” input (FOH). This is a pair of 1/4″ balanced TRS jacks. The signal fed into this input will be replicated at the stereo signal “A” output (3). The signal is available in the outputs 1-6 as the “source A” signal, but will be replaced by the signal inserted in the front-panel 3-5mm TRS socket once a jack is inserted into this socket (16).

3. Stereo Signal “A” output (FOH). This is a pair of 1/4″ balanced TRS jacks. For the purpose of forwarding the input signal to more DLA26 units or other subsystems, the signal fed into the stereo signal “A” input (2) is replicated here. It can be decided by internal jumper settings whether emergency features are carried forward on this output (see chapter “configuration” for details).

4. Stereo Signal “B” input (Main). This is a pair of 1/4″ balanced TRS jacks. The signal fed into this input will be replicated at the stereo signal “B” output (5). The signal is available in the outputs 1-6 as the “source B” signal.

5. Stereo Signal “B” output (FOH). This is a pair of 1/4″ balanced TRS jacks. For the purpose of forwarding the input signal to more DLA26 units or other subsystems, the signal fed into the stereo signal “B” input (4) is replicated here. It can be decided by internal jumper settings whether emergency features are carried forward on this output (see chapter “configuration” for details).

6. Stereo signal output (outputs 1-6, visualized at output 4). This is a pair of 1/4″ balanced TRS jacks. This output will carry the signal selected with the input selector switch (23) in the relative outputs control section on the front panel. It will be influenced by the other controls in the relative outputs control section on the front panel and the settings made on the relative outputs section on the rear panel.

7. Stereo signal output (outputs 1-6, visualized at output 4). This is a terminal block output carrying the same signal as the balanced TRS output (6).

8. Maximum level setting (outputs 1-6, visualized at output 4). This control allows to limit the maximum level at relative stereo signal outputs (6)/(7) in order to match the connected sound system. Adjustments made on this control will not be displayed by the output peak indicator (24). Adjustments shall be made with a small screwdriver. Note that the total angle is 300 degrees; do not apply excessive force with the screwdriver. audible instead.

9. Output mono switch. This switch sets the relative outputs (6)/(7)to mono operation if the connected sound system(s) requires to do so. The mono signal will be available on both the left and right channel of outputs (6)/(7).

10. Output high pass filter (HPF). This switch activates a 1 00Hz HPF at the relative output (6)/(7). If the output feeds smaller speaker or ceiling speakers with open back, this may be a recommendable setting.

11. Music Mute input. This is a terminal block input which allows to remotely mute all stereo outputs (6)/(7) by simply shortening the contacts. Note this will affect ALL outputs.

12. Emergency input. This is an auto-sensing, balanced terminal block input which allows the connection to an emergency evacuation system. Once a signal is present on this input, the stereo output signals (6)/(7) will all be muted and the emergency message/signal from this input will become audible instead, at the volume set by the emergency level control (13).

13. Emergency volume control. This control allows to set the level with which the signal fed into the emergency input (12) will be replayed at the stereo outputs (6)/(7).
    

14. Input volume adjustment for Input “A”. This control allows to adjust the input “A” level to the source level. Make sure that the input level overload indicator (17) only flashes occasionally, to avoid excessive input levels.

15. Input mute switch for Input “A”. Press this switch to mute the input “A”. The indicator LED in the switch cap will be lit when the input is muted.

16. AUX signal input connector for input “A”. This is a 3.5mm Mini TRS unbalanced stereo socket which allows the connection of sources like MP3 players etc. without removing the unit from its mounting position. Once a plug is inserted, the rear-side connected input signal “A” is disabled and the source connected to this 3.5mm Mini-TRS is the active signal for input “A”.

17. Level Overload Indicator for Input “A”. This LED indicates that the safe input level to Input “A” is exceeded. Reduce the setting of the input volume control (14).

18. Input volume adjustment for Input “B”. This control allows to adjust the input “B” level to the source level. Make sure that the input level overload indicator (20) only flashes occasionally, to avoid excessive input levels.

19. Input mute switch for Input “B”. Press this switch to mute the input “B”. The indicator LED in the switch cap will be lit when the input is muted.

20. Level Overload Indicator for Input “B”. This LED indicates that the safe input level to Input “B” is exceeded. Reduce the setting of the input volume control (18).

21. Output volume control for outputs 1/2/3/4/5/6. Allows the adjustment of the volume of the relative output. Note the final level is also influenced by the rear-side maximum level control (8).

22. Equalizer for outputs 1/2/3/4/5/6. Allows the adjustment of the tonal balance for the respective output in two frequency bands with an adjustment range of ±12dB.

23. Source selector switch for outputs 1/2/3/4/5/6. Allows the selection of Input “A” or “B” as the source for the relative output. The pressed position selects input “B”, and the indicator LED in the switch cap will be lit.

24. Output peak Indicator for outputs 1/2/3/4/5/6. This LED indicates that the output level exceeds +4dBu. Reduce the level with the output volume control (21 ).

25. Power switch. Switches the unit on and off. Make sure to switch the unit off when not in use. The ON position is indicated by a backlight.
