D D MM 4/2/2
Install the DMM 4/2/2 in your 19" rack using the supplied screws and washers.
If you need more than four microphone channels, you can daisy-chain several DMM 4/2/2.
Using the expansion connectors on the rear panel, up to five units of the same type can be
daisy-chained and operated as a single unit. This gives you up to 20 balanced input channels
and 10 AUX input channels. The master output and the recording output are only available on
the master unit.

Figure 8: daisy-chaining multiple units
All units independently detect whether they are master or slave units, according to the
following principle: if a unit is not connected to any other unit by means of its "TO MASTER"
jack, it is the last link in the chain of units. It therefore recognises that it should act as the
master unit.
The expansion cable must not exceed 20 cm in length. We recommend original AKG
accessories.
ATTENTION
Read through the operating instructions of your microphones and auxiliary equipment before
connecting them.
NOTE
Connect the microphones and auxiliary equipment to the rear panel of the DMM 4/2/2:
1) Connect the microphones and other audio sources (e.g. receivers for wireless
microphones) to the "MIC/LINE" input channels.
2) Connect your auxiliary equipment (CD player etc.) to the "AUX" inputs using the RCA
cables.
3) Connect the output channel "OUT - MASTER" to a mixing console or amplifier.
4) Connect the RCA jacks of the recording output "OUT - REC" to a recording device.
Connect the hardware (that you want to remotely control using the DMM 4/2/2) to the
DMM 4/2/2 via the 26-pin D-sub "CONTROL IN/OUT" high density jack.
