to play "Left (A)", "Right (B)" or
"Left+Right (A+B)" channel.
Adjust the desired maximum SPL at
1m for a full scale digital signal using
the "DIGITAL LEVEL" switches. This
compensates for differing amounts
of headroom on the digital signal and
enables the speaker to work at its
maximum SPL if required. The "DIG-
ITAL LEVEL" can be set to 112, 100 or
88 dB SPL at 1m with a full scale sine
wave digital signal.
The "LEVEL CONTROL" trimmer ad-
justs the level of both the digital and
analog signals. Use this trimmer to
give the digital level an extra 0 to -12
dB attenuation in addition to the "DIG-
ITAL LEVEL" switches. Combining
these makes it possible to adjust the
maximum SPL at 1m for a full scale
sinusoidal digital signal anywhere be-
tween 112 dB and 76 dB.
Switch on the mains power and feed
an AES/EBU digital signal to the sys-

age, and place the loudspeakers at
their listening position, taking note of
the reference axis (see figure 1). The
reference axis should be aimed di-
rectly at the listening position. En-
sure that the mains switches are off
and connect the mains cables.

Connect a digital audio interface ca-
ble to your digital audio source. You
can identify the right connector on
your audio source by looking for the
words “Digital Output” or “AES/EBU
OUT”. Make absolutely sure that the
connectors are carrying the AES/EBU
formatted digital audio signal. NEV-

Connect the digital signal cable to
the "DIGITAL INPUT" female XLR con-
nector on a S30D (see figure 2). Next
connect a second signal cable from
speaker's "DIGITAL THRU" male XLR
connector to the "DIGITAL INPUT"
connector of another S30D as shown
in Figure 3 below. You can daisy-chain
practically any number of S30D's in
this manner. Figure 4 overleaf shows
an example of a cabling scheme for
a digital 5.1 channel console.
Use the "CHANNEL SELECT" switch-
es to select loudspeaker mode. Any
