Introduction Co n t rol el e m e nts Block Diagram Applications Spec if ications

1.INTRODUCTION

The MX-880 is designed to meet highest requirements:
professional recording, broadcast and television studios,
CD and digital production facilities, etc. Much like an all­in-one tool, it provides virtually unlimited configurations.
Be it the distribution of a stereo signal to several outputs
(splitter); the combination of separate signals to one
stereo output (mixer), or the specific level adaption of
individual signals.

Basically, the unit consists of six mono channels, which can
be used either as a splitter or as a mixer. For instance, a
stereo program source can be inserted via the main input to
be subsequently routed to any of the mono channels that are
set to SPLIT mode. Using the individual BALANCE/PAN
control, you can - for each channel - determine the ratio
between the left and right main input signals that are routed
to the corresponding output of the channels. Thus, the
stereo input signal coming from the main input section can
be distributed selectively among the six mono output
channels.

In MIX mode, the input signals from the respective
channel(s) can be mixed at the stereo main output, with the
individual BALANCE/PAN control determining the signal ratio
between the left and right main outputs (pan function). It is of
particular advantage that, in MIX mode, the stereo input
signal from the main input section is alternatively routed to
the main outputs. By using this feature a total of up to 8
single signals can be combined.

In MIX mode, the mono input signals are simultaneously
applied to the respective mono outputs, which permits each
channel to be used as an individual matching amplifier. The
LEVEL controls in the corresponding channels enable the
user to adapt the levels at will, with a maximum gain of +15
dB. Levels used in home-

converted into studio levels (+4 dBu), and vice versa.

recording can therefore be

high operating levels. Externally induced mains hum etc. will
be effectively suppressed. The automatic servo-function
recognizes the presence of unbalanced connectors and
adjusts the nominal level internally to avoid level differences
between the input and output signals (correction 6 dB).

1.3 Rack mounting

The Unika MX-880 fits into one standard 19" rack unit of
space (1 3/4"). Please allow at least an additional 4" depth
for the connectors on the back panel. Be sure that there is
enough air space around the unit for cooling and please do
not place the MX-880 on high temperature devices such as
power amplifiers etc. to avoid overheating.

1.4 Mains voltage

The Unika MX-880 is equipped with Universal Mains
Voltage Switch Mode Power Supply.

1.5 Audio connections

The audio inputs and outputs on the Unika MX-880 are fully
balanced. If possible, connect the unit to other devices in a
balanced configuration to allow for maximum interference
immunity.

1.1 Typical applications

The MX-880 is one of the most flexible systems of its type.
The following applications can be realized:

2 IN/8 OUT splitter, 8 IN/2 OUT mixer, 6 IN/6 OUT matching
amplifier or any other combination.

 Keyboard submixer

 Distribution amplifier for P.A. systems, discotheques,

theatres, churches, hotels, communication systems, etc.

 Add-on module for mixer channels

 Add-on module for effect and monitor paths

 Level translator from -10 dBV to +4 dBu etc.

1.2 Balanced inputs and outputs

As standard, the Unika MX-880 is installed with electronically
servo-balanced inputs and outputs. The new circuit design
features automatic hum and noise reduction for balanced
signals and thus allows for trouble-free operation, even at
