11 DISTRIBUTION UNIT DA-240
INPUT SIGNAL MONO/STEREO SWITCH
When this Mono/Stereo switch placed in the front panel, is placed in the MONO
position of each one of the stereo input (A and B), the DA-240 unit take the L input signal
and send it to the two DA-410 L and R inputs.
With this switch in the Stereo position, each DA-410 stereo input, take the input
signal from the correspondent input, L or R.
OUTPUT SIGNAL ATTENUATOR SWITCH
The distribution unit incorporates an output signal attenuator, by each one of the 40
outputs, this allows adapt the signal output level to the final device. In the 0 position, the
signal is not attenuates, in the position —10 the signal is attenuated 10 dB and in the position —20, the
signal is attenuated 20 dB.
5. OPTIONS
In this section will explain the different available options for the distribution unit DA-240.
OUTPUT TRANSFORMER (OT-DA)
In order to get a galvanic isolation with the next part of the audio system, it is available an
output transformer.
Each two XLR-3-32 outputs there are an insert point for the output transformer; therefore, you
could mount twenty output transformers in the unit.
The provided transformers fulfil the isolation rule of 2 kV.
SET OF PHOENIX TO XLR CABLE LINKS (MC-240)
Input and output cables to connect the distribution unit DA-240 to the active distribution unit
DA-410.
FLIGHT CASE (FC-240)
Flight case and two vented panels to the distribution unit DA-240 and the active distribution
unit DA-410.
6. SPECIAL OPERATIONS
In order to set-up some of the distribution unit possibilities, the unit must be opened, clearing the
fourteen lateral screws, as well as all the XLR male and female screws of the front panel.
NOTE: This type of operations takes place with the unit open, for what it should be carried out by a
qualified technician.
DANGER:
Before opening the unit, disconnect it from all the other units.
CAUTION:
Protect the distribution unit from the rain and moisture, mainly if it is open. If liquid is spilled
into the unit, consult a qualified service technician.
