Product operation
Connecting to mains power
The 8c accepts AC mains voltages between 110 and
230 V and net frequencies between 50 and 60 Hz.
There is no dierence in amplier output power
between 120 V and 230 V mains voltages. An IEC
power cord, suited to your regional power outlets,
is supplied with the 8c. Plug it into the IEC receptacle
(13), then plug the other end into your wall socket.
Status LED
The logo on the 8c’s front (3) doubles as a status
indicator.
··O: the loudspeaker is switched o entirely
··Dimmed pulse: the loudspeaker is in standby
mode
··Bright pulse: the loudspeaker is muted
··Quick pulse: there is an error. Open the Dutch
& Dutch app to see what is wrong. Alternatively,
try performing a software reset (see “Settings
pushbutton”). If the fault can not be remedied,
contact your Dutch & Dutch representative.
··On: the loudspeaker is switched on.
In case the illumination of the logo is undesirable,
it can be dimmed or switched o from the
Dutch & Dutch app. Please keep in mind that the
loudspeaker’s status can only be monitored through
the app in this case.
Connecting to a local area network
The 8c has an RJ45 receptacle (9), which can be
used to connect it to your local area network
(LAN), allowing the Dutch & Dutch app to nd your
speakers.
The 8c will work perfectly without a LAN connection:
it is only required in case you wish to access
equalizer settings.
Audio input
The 8c can be connnected to either digital (AES3)
or (balanced) analog sources. There is one female
XLR connector (6) that can be used to present these
signals to the 8c. Make sure the correct preset is
selected (see “Settings pushbutton”).
Although it may be possible to connect unbalanced
sources with adapter cables, proper functioning
with regard to hum and noise is not guaranteed.
Dutch & Dutch strongly recommends that balanced
sources be used in order to obtain optimal gain and
sound quality.
Outputs
There is a male XLR loopthrough (7) connector
that can be used to loop the signal through the 8c.
Make sure that both loudspeakers are set to the
correct AES3 channel in case you are looping an
AES3 signal from one 8c to the other. (See “Settings
pushbutton”).
The second male XLR connector (8) is a balanced
analog output, intended primarily for use with an
external active subwoofer. Various ltering and
equalization options such as high– and low pass
lters, peak lters, delays and phase inversion can
be applied to this output.
Since there is no pre-set low-pass lter on this
output, it can also be used as a fullrange ltered
output.
Settings pushbutton
Basic settings can be adjusted with the "Set input"
pushbutton (10) on the rear panel. Pushing the
button briey will toggle the input setting between
the analog high level (+4 dBu), analog low level (-10
dBV), AES3 left channel, AES3 right channel and
AES3 mono input settings. The four LEDs indicate
the selected setting.
