ZONE-MIX 4/8 DIGITAL - INTRODUCTION
ZONE-MIX is based on the well-proven technology of ITEC MULTIMIX. It is a device that is designed specifically for
the easy distribution of up to four input signals to eight output zones. The ZONE-MIX provides the sound engineer
every imaginable possibility of signal processing while offering the operator a very simplistic user interface.
The new ITEC ZONE-MIX 4/8 digital is very reasonably priced, so you can also use it for simple sound provisioning
setups. Simultaneously, it is perfectly suited for large and complex setups due to the ability to cascade multiple
instances, the high audio quality and the remote control and –maintenance features.
Connectivity and configuration are both simple and self-explanatory. The configuration software ITEC SPLITDESIGN
is clearly arranged and for free download on our homepage:

ZONE-MIX 4/8 DIGITAL - CONTROLS
With the ZONE-MIX 4/8 digital, it is very easy to do manual adjustments: just use the potentiometers on the front
panel. The eight volume controls can be allocated to the in- and outputs as desired. Two controls are available to
adjust the inputs. Obviously, you can also group inputs or outputs to a single control. You can allocate 1 input to each
of the outputs using a small button.
The front panel features four LEDs that indicate the input signals, a power indicator and a fault indicator LED.
Serial Interfaces
Two independent RS232 interfaces allow for connectivity to other systems. The 9-pin PC connector is located on the
front panel. The configuration software ITEC SPLITDESIGN turns any PC or Laptop into a fully-featured operational
console with rich status display. The rear panel also features a 9-pin connector to link to media remote controls.
Inputs
4 symmetric inputs on XLR-sockets are located on the rear panel. The maximum input amplification is adjustable
for each channel from -20 to +30 dB in Line-operation and from +10 to +60 dB in Mic-operation. That means that
you are able to adjust any common playback devices and microphones to optimum levels. Phantom power (12 V) is
available and can be activated separately on each channel. Additionally, you can connect a MULTIMIX 8/4 via the
RJ45 connector of the ZONE-MIX (ANALOG LINK IN), using its ANALOG LINK OUT connector.
Outputs
8 symmetrical outputs are available as XLR connectors on the rear panel. The maximum output levels are +20 dB (if
the DSP module is installed: +10dB)
External Control
Volume remote control is possible using the remote control inputs (15-pin connector on the rear panel). There are
8 remote control inputs that can be connected to external potentiometers (direct current 0-10V). You can allocate
any input or output channel to the remote control inputs. Configuration changes can also be performed using these
inputs. An external switch can be used to activate one of up to 10 user-defined configurations.
Ethernet Interface (optional)
If you order the your device with the optional Ethernet interface (RJ45 connector on the rear panel), you can configure
and remote control it via your PC or Laptop network connector.
Fault Indicator
A potential-free switch is available for connectivity to external fault indicator systems.

ZONE-MIX 4/8 DIGITAL - BLOCK DIAGRAM
The base architecture of the ITEC ZONE-MIX is built from high-quality analogue audio technology! However, fully
digital controlled. Two microprocessors control the VCAs, measure the potentiometers and audio levels, switch the
signal paths and communicate with external systems. The analogue base architecture provides for superior quality
in terms of signal-noise ratio, dynamics and harmonic distortion. You can optionally extend your device with two
DSP modules (for four outputs each) if you would like to also perform digital signal processing.

ZONE-MIX 4/8 DIGITAL - DSP MODULE (OPTIONAL)
You can optionally add up to two 4x4 DSP matrix modules to your ITEC ZONE-MIX. ITEC SPLITDESIGN includes
to configure these DSPs. They operate in 24 Bit / 44,1 kHz mode and provide optimal algorithms. Each DSP has 9
filters per input that can be parameterized. Attenuation, quality and frequency can be adjusted. Each output can be
delayed (0.023 – 500 ms) and filtered by setting a high/low-pass filter (1. to 4. order)

ZONE-MIX 4/8 DIGITAL - PC SOFTWARE FOR ITEC ZONE-MIX 4/8 DIGITAL
The software SPLITDESIGN is the tool that the sound engineer can use to perform basic configurations as well as
to test and adjust the ZONE-MIX in productive operation. Any adjustments can be made in real time, they take effect
immediately. Configurations are stored to the flash memory of the ZONE-MIX controller, so they are safe from poweroutages. That includes all settings and parameters and the custom names of the inputs and outputs. The sound
engineer can access all data of the last configuration at any time. You can save up to 10 different configuration sets
in the flash memory of the ZONE-MIX.
You can download ITEC SPLITDESIGN free of charge at
http://www.itec-audio.com/download/splitter/splittersetup.exe
Configuration at a click
All basic settings are performed
on this clearly laid-out screen.
The pre-amplification (Mic/Line),
the volume controls, the allocation from the inputs to the busses
and the parameters for the automixing are all configured on this
screen.
All levels at a glance
The screen “VU DISPLAY” shows
the current levels of inputs and
outputs during operation. It is a
valuable tool to check correct
adjustment of the device.

DSP Inputs (only with DSP option)
This screen allows to configure the 9-band
equalizers and the matrix mixer. You can edit
settings directly in the graph – it’s a breeze!
DSP Outputs (only with DSP option)
On this screen you can configure the band-pass
filters for the 8 outputs. Also, you can comfortably set
delays in milliseconds, meters, or feet.
One tool of many:
Compressor/Limiter
You will find many valuable features in the
corresponding menu “EXTRAS”. One of
them is the compressor/limiter. The display
is real-time to make optimal configuration
easy. The compressor operates in analogue mode on the signal path, but is also
microprocessor controlled.
Visualization of the configuration
The configuration setup is visualized in this diagram.
Signal paths are illustrated as coloured lines, the
diagrams of filters and equalizers explain the architecture very well. You can click on parts of the
diagram to see current signal levels and additional
information.
