10 LED indicators
ON
= Power indicator
SIGNAL = Signal indicator
LIMIT
= Limiter indicator: Lights up
when the signal level is too
high; the limiter will reduce the
signal level to protect the
speaker.
11 Input MIC IN (combined 6.3 mm jack / XLR,
bal.) to connect a microphone
12 Stereo input LINE IN (combined 6.3 mm
jacks/ XLR, bal.) to connect a signal source
with line output level (e. g. mixer, CD / MP3
player)
13 Output LINE OUT (XLR, unbal.)
At this output, the signal of the input LINE
IN (12) is available; either as a mono sig-
nal or only the signal of the right channel,
can be selected by means of the selection
switch (14).
14 Switch to select the operating mode
MONO =
The speaker column repro-
duces the signal of the input
LINE IN (12) monophonically;
the monophonic input signal is
available at the output LINE
OUT (13).
RIGHT =
The speaker column repro-
duces the left channel of the
input LINE IN; the input signal of
the right channel is available at
the output LINE OUT.
15 Mono input COMBI IN (combined 6.3 mm
jack/ XLR, bal.) to connect a microphone
16 Stereo input AUX IN (RCA jacks and 3.5
mm jack, unbal.) to connect a signal
source with line output level
17 Output MIX OUT (XLR, unbal.) to send the
mixed mono signal to an additional ampli-
fier, for example
18 Output REC OUT (RCA) to connect a re -
corder
At this output, the mixed stereo signal is
available.
19 Support for the mains fuse
Always replace a blown fuse by one of the
same type.

Safety Notes
The unit corresponds to all relevant directives
of the EU and is therefore marked with
.
G
The unit is suitable for indoor use only. Pro-
tect it against dripping water and splash
water, high air humidity and heat (admissi-
ble ambient temperature range: 0 – 40 °C).
G
Do not place any vessel with liquid on the
unit, e. g. a drinking glass.
G
Do not operate the unit and immediately
disconnect the mains plug from the socket
1. if the unit or the mains cable is visibly
damaged,
2. if a defect might have occurred after the
unit was dropped or suffered a similar
accident,
3. if malfunctions occur.
In any case the unit must be repaired by
skilled personnel.
G
Never pull the mains cable to disconnect
the mains plug from the socket, always
seize the plug.
G
For cleaning only use a dry, soft cloth; never
use water or chemicals.
G
No guarantee claims for the unit and no lia-
bility for any resulting personal damage or
material damage will be accepted if the unit
is used for other purposes than originally
intended, if it is not correctly connected or
operated, or if it is not repaired in an expert
way.
3 Applications
The active 3-way column speaker system
C-RAY/ 8 can be used for various PA applica-
tions. The individual components of the
C- RAY/8 (1 subwoofer module, 2 column
modules) can be connected so that the
C- RAY/
8 is also ideally suited for mobile
applications. Two class D amplifiers, each
with a power of 200 W
RMS
, are available for
the low-frequency and the mid-high frequency
ranges.
Two audio units and two microphones can
be connected to the 4-channel mixer unit. For
sound adjustment and frequency splitting, the
audio signals pass a digital signal processor
(DSP) that also includes a signal limiter.
4 Installation
1) Place the subwoofer module on an even,
horizontal surface (floor).
2) Start with the column module where a
6.3 mm jack is located on the upper side.
Place the column module – turned by
approx. 20° to the left – onto the connector
of the subwoofer module and then turn it to
the right stop so that it is firmly engaged.
3) Proceed in the same way to connect the
second column module to the first one.
4) If the tweeters located in the centre of the
connected columns do not have the opti-
mal height (earʼs height), use the adapter
piece C-
RAY/
8EXT (available as an
option) to increase the height of the col-
umn modules.
5 Connecting the Units
To avoid interfering noise, switch off the
speaker system or turn the controls LINE,
MIC, COMBI and AUX (1 – 4) to the position
MIN prior to connecting/disconnecting.
5.1 Microphones and audio units
1) To connect microphones to the balanced
jacks MIC IN (11) and COMBI IN (15), use
an XLR plug or a 6.3 mm plug.
2) Various input jacks are available for the
connection of audio units (e.g. mixer,
receiver of wireless microphone systems,
CD/MP3 player):
Stereo input LINE IN (12):
The jacks (combined 6.3 mm/XLR) are
balanced. However, it is also possible
to use 2-pole plugs to connect units
with unbalanced output.
Stereo input AUX IN (16):
The RCA jacks or the 3.5 mm jack can
be used.
3) For audio recordings, connect the input of
a recorder to the RCA jacks REC OUT
(18). At these jacks, the mixed signal
adjusted by means of the controls LINE,
MIC, COMBI and AUX (1 – 4) is available.
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harm-
ful to the environment.
WARNING The unit is supplied with danger-
ous mains voltage. Leave servic-
ing to skilled personnel only!
Inexpert handling may result in
electric shock.
