The DAB1 has input and output connections for four source components. The
corresponding SOURCE INPUT and SOURCE OUTPUT connectors are arranged
vertically (see
Figure 6
). The SOURCE OUTPUT connections are buffered.
SOURCE INPUT Connections
Connect a stereo RCA audio cable from the left & right line-level audio
outputs of a source component to one set of left & right SOURCE INPUT jacks
on the DAB1. You can connect up to four source components.
Source 1 INT TUNER/EXT IN Switch
The Source 1 INT TUNER/EXT IN Switch assigns either the DAB1’s internal
FM/AM tuner or the component connected to the #1 SOURCE INPUT jacks as
Source 1.
SOURCE OUTPUT Connections
FFoorr RReeccoorrddiinngg::Connect a stereo RCA audio cable from one set of DAB1 L&R
SOURCE OUTPUT jacks to the record inputs on the recording device. This allows
the source component connected to the corresponding SOURCE INPUT jacks to be
recorded.
WWhheenn UUssiinngg MMuullttiippllee DDAABB11 CCoonnttrroolllleerrss::In a system that incorporates multiple DAB1s, you can feed up to four
common sources to any or all of the controllers.
1. Designate one DAB1 as the PRIMARY controller and the others as SECONDARY controllers.
2. Connect the source components to the SOURCE INPUTS on the PRIMARY DAB1 as described above.
3. For each source that you want to feed to the SECONDARY controllers, connect a stereo RCA audio cable from its SOURCE
OUTPUT Jacks on the PRIMARY DAB1 to the corresponding set of SOURCE INPUT jacks on the SECONDARY DAB1 (SOURCE 1
OUT to SOURCE 1 IN, etc.). You can repeat this for up to four DAB1 Controllers (24 zones). This will feed audio from up
to four common sources to all zones in an expanded system.

Use Good Speaker Wire
For the best sound you should never use thin-gauge speaker wire – it will constrict the sound and diminish bass response.
We recommend that you use premium Sonance MediaLinQ speaker cable, which also complies with UL fire rating codes. You
may also experiment with audiophile brands of speaker cable, but be sure to check local codes governing wire that
may be installed within walls or ceilings. Use at least 18 AWG speaker wire for runs up to 50’, at least 16 AWG for runs
up to 100’ and at least 14 AWG for runs up to 250’.
