5. Connecting audio signals
Please keep loudspeakers switched off while
connecting cables.
The 6040R accepts both analogue line level
audio and digital audio (see figure 2). Figures
3 and 4 illustrate the audio cable routing. We
recommend that you use an AES/EBU digital
audio signal, but you can also use SPDIF
digital audio when the signal cable is less than
3 metres, providing you use a digital audio
impedance converter between the SPDIF output
and the AES/EBU input.
Digital audio signals typically carry two audio
channels. The digital audio ‘Thru’ output may be
used to connect to the next 6040R loudspeaker.
Each loudspeaker is designated to a specific
channel when digital audio is used. This can
be done via the GLM software during the
system setup phase or with the “DIGITAL A”
and “DIGITAL B” switches on the base panel of
the 6040R. In larger systems, pairs of channels
are carried in each cable and sent to two
loudspeakers, for example in a 5.1 multichannel
system where cable 1 could carry Front L + R,
cable 2 Front C + LFE and cable 3 Rear L + R.
If your system also uses a subwoofer, the digital
audio signal can also be run to it.
Figure 5 shows the GLM control network
cabling and components. For this you’ll need
both the GLM Kit and GLM software. The GLM
Kit contains an interface for computer USB
