EN Dateq ManualTRI-O Introduction 3
Dateq TRI-O
The DATEQ is a s channel 19-inch mixer. It is highly suitable for use in pubs, dancing-TRI-O ix 3-zone
schools, conference centres etc. The is equipped with three microphone inputs andTRI-O 8
stereo-line inputs. The inputs can be routed to the 3 master outputs.
Channel 1 has a talk-over circuit to improve the speech intelligibility. This circuit, which is triggered
by the microphone signal from channel 1 (i.e. it is voice-activated), ensures that this signal
overrides all others. The talk-over function can be disabled with the TalkOver switch on the front.
By default output zones are available (master A and ). These zones have a dualthree , B C
equaliser, balance and gain-control. In addition a maximum of four output modules (output zones)
may be added. The volume of these additional zones is externally adjustable with a potentiometer
CREWXOUT-W / CREWXOUT-B (not included) or an external regulation voltage.
The master s areoutput electronically balanced on XLR and unbalanced on cinch connectors. The
balanced output makes it possible to use long signal-cables so that the amplifiers can be placed
near to the speakers. he optional output zones are equipped with unbalanced cinchT conne tors.c

an opening of 445 x 132 x 110 mm (W x H x D). See also the dimensioned drawings below.
The 19-inch mounting bracket is 2mm thick. When installing the mixer, remember to allow sufficient
room for the connectors and plugs on the Crew’s rear!

MASTER L/ R
Electronically balanced master outputs on XLR connectors for the left and
right channels of master A. This type of output guarantees perfect signal
transmission even if long audio cables are being used. These outputs are
equipped with relays to prevent connected equipment from ‘plopping’ when
the unit is being switched on and off.
MASTER
Unbalanced outputs on cinch connectors. These can be used to connect
the Crew to an amplifier or recorder. These outputs are equipped with relays
to prevent connected equipment from ‘plopping’ when the unit is being
switched on and off.
ZONE 1...4 Audio out With these outputs additional zones with separate external volume control
can be created. These outputs can be used to connect external amplifiers.
ZONE 1...4 Volume This input controls the volume of the additional zone. Between the tip and
the shield a potentiometer or an external control voltage can be supplied.
See page 7 for a more detailed explanation.
CHANNEL 7...3 Cinch connectors for the stereo line inputs. Each channel has two identical
inputs (line 1 and line 2) for CD-players, keyboards, MD-players etc. With
the input-selector on the front on of the two inputs can be activated. Each
input has it’s own gain-trimmer at the rear.
CHANNEL 2 Combined mono mic/ stereo line channel with a balanced (or local input)
microphone input on a XLR-connector and a stereo line input on a cinch
connector. When using an unbalanced microphone pin 1 and pin 3 must be
connected to the shielding of the cable. To use a local zone input connect
CHANNEL 1 This channel has two electronically balanced microphone inputs on XLR-
connectors (Mic Front and Mic Rear). When using an unbalanced

Zone volume control
By means of this input the volume of an external zone can be adjusted. The volume control can be
connected in two different ways:
Supplying an external voltage
When a voltage is supplied between the tip and the shielding of one of the cinch-connectors the
volume will be attenuated (for both the left and the right channel). When a negative voltage is
supplied the signal will be amplified. The amplification ranges from +14...-80dB. The graph below
shows the amplification as function of the applied voltage:
Connecting a potentiometer
It is also possible to connect a potentiometer between the tip and the shielding to one of the cinch
connectors. The attenuation ranges from 0...-80dB. A 10kOhm logarithmically potentiometer gives
the best results. The next graph shows the attenuation as function of the angle of rotation:
As a maximum four
additional output zones can be connected.
When an adjustable attenuation is not necessary a cinch connector with a short-circuit between the
tip and shield must be connected. When the input is left open the volume will be fully attenuated.
