Connecting digital AES3id and S/PDIF signals to the loudspeaker
X
Connect the digital AES3id or S/PDIF output signal of your audio source to the DIGITAL S/
PDIF INPUT socket on the first loudspeaker (see figure below) .
The loudspeaker only supports non-encoded AES3 and S/PDIF signals . Encoded signals
such as MP3, DTS or Dolby Digital are not supported . The cable connection must be
unbalanced with a characteristic impedance of 75 Ω .
Only one cable is needed for uncompressed AES3 and S/PDIF digital signals (single-wire
mode) . They contain two audio channels: “subframe A” and “subframe B .” Usually, the
audio channels are:
Subframe A Subframe B
Left Right
Center LFE
Surround left Surround right
Back left Back right
A clock input is not required because loudspeakers are not audio sources and the con-
verters are clocked to a very stable internally generated clock source .
If the signal source is based on internal digital signal processing, it is recommended
that you choose a digital connection between the signal source and the loudspeaker .
This eliminates the need for additional signal conversion from digital to analog in the
source and from analog to digital in the loudspeaker . This also applies if you are con-
necting to an upstream DSP subwoofer (e .g . KH 750 DSP) . This should be connected to
the loudspeakers via its digital output .
Note that the supplied digital signal often has a maximum signal level, and that the
level in the source is often not adjustable . Therefore, before making the digital connec-
tion, set the OUTPUT LEVEL switch on the loudspeaker to 94 dB SPL and the INPUT GAIN
knob to -15 dB .

Connect the DIGITAL S/PDIF OUTPUT socket on the first loudspeaker to the DIGITAL S/PDIF
INPUT socket on the second loudspeaker .
X
Set the INPUT SELECT switch on the left loudspeaker to S/PDIF L and the INPUT SELECT
switch on the right loudspeaker to S/PDIF R . The CONTROL switch must be in the
Local
position .
