Dateq ONYX Manual Introduction

Dateq Onyx
The Onyx is a 6-channel mixer with a clear and uncluttered appearance. It is highly suitable for
use in -among other situations- conference centres, catering establishments, small discotheques
and hotels. A total of three microphones and nine line signals can be connected. Channels 1 and 2
both have gain and dual tone controls to improve speech intelligibility. There is an XLR connection
on the front panel to allow quick connection of an additional microphone. Channel 6 has a ‘jukebox
input’ which can be used to suppress the signal of channels 2-5.
The zone system makes it possible to retrieve two different signals from the unit. This means, for
example, that people in the front room of a complex can listen to a CD player while, in the back
room, a meeting is taking place via the same sound system. It is also possible to route a signal to
both outputs, so that, for example, a general announcement will always be heard. Each channel
has an A/B switch which can be used to route the channel concerned to output A or B (or to both).
Thanks to the built-in talkover circuit, announcements and/or paging calls always come over
clearly. This circuit, which is triggered by an incoming signal on channel 1 (i.e. it is voiceactivated), ensures that this signal overrides all others. The talkover’s actuation point is adjustable,
and the talkover function can be switched on and off using a switch on the front panel.
The Onyx has two stereo outputs which are completely independent of one another. Each is fitted
with a triple tone control to allow precise acoustic correction. Master A has both balanced and
unbalanced outputs. This makes it possible to use long signal cables and to locate the (output)
amplifier for this group close to the loudspeakers. Master B has unbalanced outputs. The mixer
also has easy-to-read LED VU meters which show which CUE signal has been selected.

Dateq ONYX Manual Installation
EN
Installing the Onyx
The Onyx has been designed to be installed in a standard 19" rack mounting. This is why all the
connectors have been located on the rear. The cabinet fits into an opening of 445 x 217 x 105 mm
(W x H x D). See also the drawings below.
The front panel is 3 mm thick. When installing the mixer, remember to allow sufficient room for the
projection of the buttons on the front and for the connectors and plugs on the Onyx’s rear!

Dateq ONYX Manual Connecions

Onyx connector board
On the underside of the Onyx you will find the connectors for all the audio inputs and outputs. Also
located here are the Euro mains socket with built-in mains fuse and the jukebox input. These
connectors were deliberately placed on the underside because, in many cases, the Onyx will be
installed in a standard 19" rack mounting. This arrangement ensures that the connectors do not
take up unnecessary space in the rack.

Connections
BALANCED
MASTER L/ R (A)
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 A/ B Unbalanced outputs on cinch connectors. These can be used to connect the
Onyx to an amplifier or recorder.
CHANNEL 6..3 Cinch connectors for the stereo channels. Each channel has two identical
inputs at line level (Line 1 and Line 2) for connecting equipment such as CD
players, keyboards and recorders. The input selector on the front panel can
be used to select which input is to be active. Channel 6 is fitted with a
jukebox input which can be used to interrupt channels 2-5.
CHANNEL 2 Combined mono Mic/Stereo Line channel with an electronically balanced
microphone input on an XLR connector and a stereo cinch input at line level
(-14 dB sensitive). If the microphone is being used in unbalanced mode, pins
1 and 3 should be connected to the shield of the microphone cable.
CHANNEL 1 This channel has two electronically balanced microphone inputs on XLR
connectors (Mic Front and Mic Rear). If the microphone is being used in
unbalanced mode, pins 1 and 3 should be connected to the shield of the
microphone cable.
FUSE Mains fuse. Dimensions 5 x 20mm (small), 315mA slow.
MAINS Euro mains socket. The Onyx operates at a mains voltage of 230V.
For all cinch connectors:
White = Left, Red = Right
Jukebox input
This input can be used to interrupt the signal of channels 2-5 of output A and/or B. In this case only
the signal of channel 1 (microphone) and channel 6 (stereo line) will still be passed on.
The jukebox input is only active if channel 6 is routed to output A and/or B. If channel 6 is routed to
output A only, then the signals of channels 2-5 which are routed to output A will be interrupted when
the jukebox input becomes active. The same applies to output B.
The jukebox input can be used in 3 ways:
n.o. Connect a switch with a make-contact (normally open) between Tip and Ring. Jukebox
becomes active as soon as the contact is made.
n.c. Connect a switch with a break-contact (normally closed) between Sleeve and Tip/Ring
(i.e. interconnect Tip and Ring). Jukebox becomes active as soon as the contact is
broken.
voltage Connect a DC voltage of 5-24V between Sleeve (-) and Tip (+). Jukebox becomes active
as soon as the voltage is applied.

active. The channel has A/B output selection, input selection (Line 1 and Line 2) and a pre-listening
function.
A/ B Output selection. When button A is pressed the signal of this
channel is directed to output A. When talkover is active on
output A the signal of this channel is attenuated. When the
jukebox input is active the signal of any of the channels 2-5
on which button A has also been pressed is suppressed.
When button B is pressed the signal of this channel is
directed to output B. When talkover is active on output B the
signal of this channel is attenuated. When the jukebox input

Cue-function
When the Cue button on any of the channels 1-6 is pressed it is possible to monitor the incoming
signal on that channel on the headphones (pre-fader listening). With the meter, it is also possible to
read off the signal level at the selected input. The Cue buttons of output A and B can be used to
monitor the signal at this output on the headphones (after-fader listening) and to read it off on the
LED meter (what you see is what you hear).
If no Cue buttons have been pressed there will be no signal at all on the headphones.
